Description
FIELD OF THE INVENTION
[0001] The present invention relates to a grooving device for
underground structures and its construction method, which belongs
to the field of civil engineering foundation construction.
BACKGROUND OF THE INVENTION
[0002] The current tunnel construction method includes: open-cut
construction and tunneling construction with pipe jacking or
shield; open-cut construction features a large amount of earthwork,
a long construction period and a high cost; the cost of existing
tunneling construction methods is relatively high.
SUMMARY OF THE INVENTION
[0003] The present invention provides a grooving device for
underground structures and its construction method. Its object is
to overcome the shortcomings of existing technologies. Its main
advantages are as follows: Build working platforms in four working
shafts. The grooving device can excavate rock and soil, while
grouting at the back, which forms a closed cavity for further
construction. It has less influence on the surrounding environment,
which is of simple construction, good quality, a short construction
period, and a low cost.
[0004] The Technical Scheme of the Invention:
[0005] Grooving device construction method includes the steps
below:
1) Build a working platform in working shafts on both ends. 2)
Install the grooving device, so that two ends of the grooving
device are built in two working shafts; there are mainly two
methods: (a) Drill holes to thread the grooving device; (b) Groove
directly from the external side (e.g. above or on one lateral side
of the mountain); 3) The grooving device cuts grooves along the
contour line of the section of the underground structure by two
methods: (1) Carry out grooving and grouting at the same time; (2)
Carry out grooving without grouting concrete; 4) Excavate the rock
and soil in the contour line.
[0006] The grooving device consists of the excavating device and
the translation device; the excavating device mainly consists of
frame, chain blade and transmission device; chain blade consists of
chains and blades on the chain; frame consists of an in-groove
frame and both-end frame outside the groove. The in-groove frame
consists of the front frame and rear frame. The front frame is
equipped with a track for chain blade operation on the front, and
the both-end frames are separately connected to the translation
device in two working shafts and mounted with a transmission
device. The translation devices in working shafts on both ends
consist of a transmission device and chain wheels and equipped with
translation devices in working shafts on both ends. During
construction, the translation device in working shafts on both ends
drives corresponding both-end frame simultaneously to move
according to the specified structure contour track, with the
both-end frame driving the chain blades on the front-end track of
the in-groove frame along the same track and the driving device
driving the chain blade. The blades on the front track of the front
frame excavate rock and soil to groove, while the chain blade
brings the excavated rock and soil to the working shaft. In-groove
frame is in two structures:
[0007] 1) Chain blade track is mounted at the back of the front
track of the front frame, which is adopted to form a closed loop as
the chain returns. The front frame is connected to the rear frame
in the groove by two methods: [0008] (A) The total width of the
blade on the excavated face is equivalent to that of the
non-excavated face. The multi-row chain blade is in a staggered
arrangement on the non-excavated face. The front frame integrates
to the rear frame through the staggered space; [0009] (B) The
center line of the chain blade is a spatial curve. The blades
returning to the chain blade adjacent to the non-excavated face are
engaged in a staggered or overlapped way along the longitudinal
direction of the chain, i.e. the total width of the blade on the
non-excavated face is less than the total width of the blade on the
excavated face. The front and rear frames are integrated according
to this width difference;
[0010] 2) Two sets of excavating devices share one set of chain
blades, i.e. the chain of two chain blades are connected in series
to form a closed loop.
[0011] The advantages of the present invention: structure working
platforms in four working shafts enables the grooving device to
excavate rock and soil, while grouting into the rear side to form a
closed cavity for further construction, which has less influence on
the surrounding environment and is of simple construction, good
quality, a short construction period and a low cost.

DETAILED DESCRIPTION OF IMPLEMENTATION
[0037] A construction method for grooving device adopted in
underground structures mainly includes the steps below:
[0038] 1) Build a working platform in working shafts on both
ends.
[0039] 2) Install the grooving device, so that two ends of the
grooving device are built in two working shafts; there are mainly
two methods: [0040] (a) Drill holes to thread grooving devices;
[0041] (b) Groove directly from the external side (e.g. above or on
one lateral side of the mountain);
[0042] 3) The grooving device cuts grooves along the contour line
of the section of the underground structure by two methods: [0043]
(1) Carry out grooving and grouting at the same time; [0044] (2)
Groove without grouting concrete;
[0045] 4) Excavate the rock and soil in the contour line.
[0046] The said grooving device consists of the excavating device
and the translation device; the excavating device mainly consists
of frame, chain blade and transmission device; chain blade consists
of chains and blades on the chain; frame consists of an in-groove
frame and both-end frame outside the groove. The in-groove frame
consists of the front frame and rear frame. The front frame is
equipped with a track for chain blade operation on the front, and
the both-end frames are separately connected to the translation
device in two working shafts and mounted with a transmission
device. The translation devices in working shafts on both ends
consist of a transmission device and chain wheels and equipped with
translation devices in working shafts on both ends. During
construction, the translation device in working shafts on both ends
drives corresponding both-end frame simultaneously to move
according to the specified structure contour track, with the
both-end frame driving the chain blades on the front-end track of
the in-groove frame along the same track and the driving device
driving the chain blade. The blades on the front track of the front
frame excavate rock and soil to groove, while the chain blade
brings the excavated rock and soil to the working shaft. In-groove
frame is in two structures:
[0047] 1) Chain blade track is mounted at the back of the front
track of the front frame, which is adopted to form a closed loop as
the chain returns. The front frame is connected to the rear frame
in the groove by two methods: [0048] (A) The total width of the
blade on the excavated face is equivalent to that of the
non-excavated face. The multi-row chain blade is in a staggered
arrangement on the non-excavated face. The front frame integrates
to the rear frame through the staggered space; [0049] (B) The
center line of the chain blade is a spatial curve. The blades
returning to the chain blade adjacent to the non-excavated face are
engaged in a staggered or overlapped way along the longitudinal
direction of the chain, i.e. the total width of the blade on the
non-excavated face is less than the total width of the blade on the
excavated face. The front and rear frames are integrated according
to this width difference;
[0050] 2) Two sets of excavating devices share one set of chain
blades, i.e. the chain of two chain blades are connected in series
to form a closed loop.
[0051] The chain blade is a multi-row chain blade, and the blade is
a self-grinding structure.
[0052] The center line of the chain of the chain blade is a spatial
curve.
[0053] The chain blade replaces chains and blades in the working
shaft, to meet different geological conditions and thickness
requirements.
[0054] The chain blade is a multi-row chain blade, and the
multi-row chain blade can excavate simultaneously or separately as
necessary.
[0055] The multi-row chain blade is arranged in a cone shape on the
excavated face.
[0056] The construction methods could be divided into method A and
method B.
[0057] The method A includes both grooving and grouting at the same
time, and concrete nozzles are equipped at the tail end of the rear
frame.
[0058] The method B is to groove only without grouting.
[0059] For the method A, a reinforcement arrangement device is
equipped at the back of the rear frame, so that the concrete after
grouting contains a reinforcement.
[0060] The working shafts are existing structures.
[0061] The present invention is further described below in
conjunction with the drawings attached.
[0062] As shown in FIGS. 1-7, the grooving device consists of the
excavating device 1 and the translation device 2; the excavating
device 1 mainly consists of frame 1-1, transmission device 1-2 and
chain blade 3; chain blade 3 consists of chains 3-1 and blades 3-2
on the chain; frame 1-1 consists of in-groove frame 1-1-1 and
both-end frame outside the groove 1-1-2. The in-groove frame 1-1-1
consists of front frame 1-1-1-1 and rear frame 1-1-1-2. The front
frame 1-1-1-1 is equipped with a track for chain blade operation on
the front, and the both-end frame 1-1-2 are separately connected to
the translation device 2 in two working shafts and mounted with a
transmission device. The translation device 1-2 consists of a
transmission device 1-2-1, tensioning device 1-2-2 and chain wheels
1-2-3 and equipped with translation devices 2 in working shafts on
both ends. During construction, the translation device 2 in working
shafts on both ends drive corresponding both-end frame 1-1-2
simultaneously to move according to the specified structure contour
track, with the both-end frame 1-1-2 driving the chain blades 3 on
the front-end track of the in-groove frame. The driving device
1-2-1 drives the chain blade 3-1, which drives the blade 3-2 to
operate. The blades 3-2 on the front track of the front frame
1-1-1-1 excavate rock and soil to groove, with the concrete nozzles
on the tail end of the rear frame 1-1-1-2 grouting concrete and the
reinforcement arrangement device 5 on the tail end of rear frame
1-1-1-2 arranging reinforcement, i.e. construction method A.
[0063] As shown in FIGS. 8-9, the excavating device 1 of the
grooving device grooves only without grouting, and the two sets of
excavating devices share one chain blade 3, i.e. construction
method B.
[0064] As shown in FIGS. 2, 4 and 5, blade 3-2 returning to chain
blade 3 adjacent to the non-excavated face of the excavating device
1 are engaged in a staggered arrangement or overlapped along the
longitudinal direction of the chain, i.e. the total width of the
blade on the non-excavated face is less than that of the blade on
the excavated face, and the front frame 1-1-1-1 and the rear frame
1-1-1-2 are integrated by this width difference.
[0065] As shown in FIG. 6, the total width of the chain blade 3 of
the excavated face of the excavating device 1 equals that of the
chain blade 3 of the non-excavated face of the excavating device 1,
and the multi-row chain blades are in a staggered arrangement on
the non-excavated face. The front frame 1-1-1-1 is integrated to
the rear frame 1-1-1-2 through the staggered space.
[0066] As shown in FIGS. 10-13, a working platform and a
translation device 2 are built in the two ends of the working shaft
with the steel wire rope 6 adopted to thread the chain blade 3
through holes drilled, and then through the excavating device 1.
The translation device 2 drives the excavating device 1 to move
along the contour line of the structure from the bottom, while the
excavating device 1 rotates along the contour line.
[0067] As shown in FIGS. 14-17, the construction method A of the
grooving device: while the excavating device 1 of grooving device
grooves along the contour line of underground structure
cross-section, carry out grouting and finally clear the rock and
soil within the contour line of concrete.
[0068] As shown in FIGS. 18-21, the construction method B of
grooving device: while the excavating device 1 of grooving device
grooves along the contour line of underground structure cross
section, carry out grouting and finally clear the rock and soil
within the contour line.
