Description
FAST TUNNEL LEAKAGE STOPPAGE CONSTRUCTION DEVICE
The present invention relates to the technical field of tun- nel leakage stoppage, and in particular, to a fast tunnel leakage stoppage construction device.
Since surrounding rock may be disturbed during tunnel excava- tion, surrounding rock deformation and fracture extension and con- duction will be caused, thereby causing seepage of underground wa- ter in rock into the tunnels, changing groundwater flow fields, and causing groundwater recession. The groundwater recession re- sults in flow reduction or even cut-off of original groundwater discharge points such as spring water, thus causing new ecological problems and disputes. Therefore, tunnel seepage control and leak- age stoppage is required for not only tunnels, but also ecological protection and water resource protection. The tunnel leakage stop- page is to perform water resistance and leakage repair construc- tion for the water outlet section or water inrush of soft rock in the tunnels.
At present, a manual material supplement method is often used in the construction of tunnel leakage stoppage. However, since the tunnels have a certain height, constructors need to hold material supplement tools up to perform material supplement for the tun- nels, thus increasing the labor intensity of the constructors, making it inconvenient for the constructors to perform the materi- al supplement for crack leakage stoppage, and causing the problem of poor leakage stoppage effect.
In order to solve the above-mentioned problems, the present invention adopts the following technical solution. A fast tunnel leakage stoppage construction device includes a support plate, a suction fixing rod and a gluing mechanism. The support plate is provided with an adjusting through-slot arranged in a matrix, and the suction fixing rod is mounted in the adjusting through-slot.
An upper end face of the support plate is provided with a T-shaped sliding slot, and an electric sliding block is mounted in the T- shaped sliding slot. An upper end of the electric sliding block is provided with an arc-shaped groove, and a supporting spring rod is hinged in the arc-shaped groove through a ball joint. The gluing mechanism is mounted on the supporting spring rod, and an adjust- ing mechanism is mounted at a lower end of the electric sliding block.
The adjusting mechanism includes a connecting hole, an ad- justing groove, a compression spring, a clamping slot, an L-shaped clamping strip, a hollow boss column, ropes, lifting rings, a pull rod, and an adjusting rod. A lower end of the electric sliding block is provided with the connecting hole communicated with the arc-shaped groove, and a side wall of the connecting hole is uni- formly provided with the adjusting groove along a circumferential direction thereof. The lower end of the electric sliding block is provided with an L-shaped slot arranged along the circumferential direction of the connecting hole. A side wall of the ball joint is provided with the clamping slot uniformly arranged along the cir- cumferential direction of the connecting hole. The L-shaped clamp- ing strip is mounted in the L-shaped slot through the compression spring, a horizontal section of the L-shaped clamping strip is lo- cated in the clamping slot, and a lower end of the L-shaped clamp- ing strip penetrates through the T-shaped sliding slot. The lower end of the electric sliding block is provided with an annular groove, the annular groove is located between the adjusting groove and the L-shaped slot, and a connecting ring is slidably connected in the annular groove. The hollow boss column is mounted at a low- er end of the connecting ring. A ball is rollingly connected to the lower end of the L-shaped clamping strip, and the ball rollingly abuts against an outer wall of the hollow boss column.
The lifting rings arranged in bilateral symmetry are mounted at the lower end of the electric sliding block. Supporting plates ar- ranged in bilateral symmetry are mounted on a side wall of the hollow boss column, and the ropes are mounted on the supporting plates. The two ropes respectively pass through the corresponding lifting rings, and lower ends of the two ropes are connected through the pull rod. The adjusting rod is mounted at a lower end of the ball joint. A lower end of the adjusting rod passes through the connecting hole and the hollow boss column. The adjusting mechanism is convenient for the gluing mechanism to inject glue into branch cracks of a crack, so as to avoid the problem that gluing leakage stoppage for the branch cracks at the edge of the crack cannot be achieved simultaneously, and prevent the occur- rence of manual secondary gluing leakage stoppage.
As a preferred technical solution of the present invention, the gluing mechanism includes an arc-shaped seat, a glue injection pipe, a supporting seat, a [-shaped frame, a preliminary shaping hot-pressing roller, a T-shaped hot-pressing plate, and fixed hot- pressing rollers. The arc-shaped seat is mounted at an upper end of the supporting spring rod, the arc-shaped seat is of an arc- shaped cavity structure, and the glue injection pipe is mounted in the arc-shaped seat. The supporting seat is mounted in the arc- shaped seat, the supporting seat is located on a left side of the glue injection pipe, and the [-shaped frame with an upward opening is mounted on the supporting seat. The preliminary shaping hot- pressing roller is rotatably connected between front and rear end faces of the [-shaped frame. The T-shaped hot-pressing plate is mounted on the supporting seat, an upper end face of the T-shaped hot-pressing plate is provided with a mounting groove, and the fixed hot-pressing rollers arranged equidistantly from left to right are rotatably connected in the mounting groove. The T-shaped hot-pressing plate, the [-shaped frame and the glue injection pipe are arranged successively from left to right. The glue may be fast solidified and shaped under the effect of double hot-rolling, thereby achieving the effect of fast leakage stoppage, and pre- venting the glue from being washed away by water leaking due to the slow solidification of the glue after gluing.
As a preferred technical solution of the present invention, left end faces of front and rear vertical sections of the [-shaped frame are separately provided with a connecting plate, upper end faces of the connecting plates are jointly provided with a scrap-
er, a right end face of the scraper inclines to the lower right, and a right end of the scraper is tightly attached to an outer wall of the preliminary shaping hot-pressing roller. The scraper scrapes off the glue adhered on the outer wall of the preliminary shaping hot-pressing roller while the preliminary shaping hot- pressing roller rotates, so as to avoid the problem that the glue is adhered and accumulated on the cuter wall of the preliminary shaping hot-pressing roller, thus making the preliminary shaping hot-pressing roller difficult to roll the glue flat.
As a preferred technical solution of the present invention, a bracket is mounted on a right side wall of the glue injection pipe, and a flow guide plate is mounted on the bracket through an abutting rod. A horizontal section of the flow guide plate is hinged to an inclined section, the abutting rod is connected to the inclined section of the flow guide plate, and an abutting spring is mounted between the inclined section and the horizontal section of the flow guide plate. A left end of the flow guide plate is close to the glue injection pipe, and the flow guide plate is provided with flow guide slots arranged equidistantly from front to rear.
As a preferred technical solution of the present invention, a steering wheel is mounted at the lower end of the adjusting rod, direction rods uniformly arranged along a circumferential direc- tion of the steering wheel is mounted on an outer wall of the steering wheel, and the direction rods are in one-to-one position- al correspondence with the adjusting grooves.
As a preferred technical solution of the present invention, an adjusting sleeve is rotatably connected between front and rear inner walls of the adjusting through-slot, the suction fixing rod penetrates into the adjusting sleeve, and the suction fixing rod and the adjusting sleeve are connected by means of threaded fit.
The suction fixing rod is formed by hinging a hollow circular rod with a suction cup.
As a preferred technical solution of the present invention, a rotating handle is mounted at a lower end of the suction fixing rod, and the rotating handle is made of rubber to achieve the ef- fect of anti-slipping protection.
As a preferred technical solution of the present invention, a square column is mounted on an upper end face of the front direc- tion rod. The square column facilitates determination of a moving direction of the glue injection pipe and prevents inversion of a 5 working sequence of the glue injection pipe and the preliminary shaping hot-pressing roller.
As a preferred technical solution of the present invention, supporting rods arranged equidistantly from left to right are mounted in the mounting groove. The supporting rod is located on the right side of the fixed hot-pressing roller, a material remov- ing plate is mounted on the supporting rod through connecting rods arranged in front-rear symmetry, and the material removing plate is tightly attached to an outer wall of the left fixed hot- pressing roller.
The present invention has the following beneficial effects. 1. The gluing mechanism designed in the present invention may be fixed to an edge of a tunnel crack through the suction fixing rod and the support plate. An injection head of the glue injection pipe on the gluing mechanism is aligned with the crack, and then a glue mechanism may inject glue along the crack without manually holding the gluing mechanism up to perform a gluing operation, thus reducing the labor intensity of workers and improving the ef- fect of crack leakage stoppage. In the presence of a branch crack, an injection direction of the glue injection pipe may be adjusted through the adjusting mechanism. While the glue injection pipe in- clines, the supporting spring rod pushes the glue injection pipe to be tightly attached to the branch crack and to inject the glue into the branch crack, thereby avoiding the problem of tedious procedures caused by manually gluing the branch crack after gluing the crack. 2. The square column in the present invention facilitates de- termination of a moving direction of the glue injection pipe and prevents inversion of a working sequence of the glue injection pipe and the preliminary shaping hot-pressing roller. 3. The suction cup on the suction fixing rod in the present invention tightly sucks together with a side wall of a tunnel, thus fixedly supporting the support plate, whereby both hands of an operator are released, and the problem that the operator holds the gluing mechanism up for a long time to glue the crack is avoided.

The embodiments of the present invention will be described below in detail with reference to the drawings, but the present invention may be embodied in many different forms as defined and covered by the claims.
Referring to FIGS. 1 and 2, a fast tunnel leakage stoppage construction device includes a support plate 1, a suction fixing rod 2 and a gluing mechanism 3. The support plate 1 is provided with an adjusting through-slot arranged in a matrix, and the suc- tion fixing rod 2 is mounted in the adjusting through-slot. An up- per end face of the support plate 1 is provided with a T-shaped sliding slot 4, and an electric sliding block 5 is mounted in the
T-shaped sliding slot 4. An upper end of the electric sliding block 5 is provided with an arc-shaped groove, and a supporting spring rod 7 is hinged in the arc-shaped groove through a ball joint 6. The gluing mechanism 3 is mounted on the supporting spring rod 7, and an adjusting mechanism 8 is mounted at a lower end of the electric sliding block 5.
Referring to FIG. 1, an adjusting sleeve 20 is rotatably con- nected between front and rear inner walls of the adjusting through-slot, the suction fixing rod 2 penetrates into the adjust- ing sleeve 20, and the suction fixing rod 2 and the adjusting sleeve 20 are connected by means of threaded fit. The suction fix- ing rod 2 is formed by hinging a hollow circular rod with a suc- tion cup.
In operation, the lower end of the hollow circular rod is provided with a circular hole in which a rubber stoppage block is mounted, and the support plate 1 is fixed at an edge of a crack of a tunnel through the suction fixing rod 2. At this moment, the suction cup on the suction fixing rod 2 tightly sucks together with a side wall of the tunnel, thus fixedly supporting the sup- port plate 1, whereby both hands of an operator are released, and the problem that the operator holds the gluing mechanism 3 up for a long time to glue the crack is avoided. The suction fixing rod 2 may rotate and move in a cylinder of the adjusting sleeve 20 so as to adjust the position of the support plate 1. After leakage stop- page for the tunnel is completed, the rubber stoppage block is pulled out of the circular hole to facilitate fast removal of the suction fixing rod 2 from the wall of the tunnel.
Referring to FIG. 1, a rotating handle 21 is mounted at a lower end of the suction fixing rod 2, and the rotating handle 21 is made of rubber to achieve the effect of anti-slipping protec- tion.
Referring to FIGS. 3, 4, 5, 8, and 9, the adjusting mechanism 8 includes a connecting hole 80, an adjusting groove 81, a com- pression spring 82, a clamping slot 83, an L-shaped clamping strip 84, a hollow boss column 85, ropes 86, lifting rings 87, a pull rod 88, and an adjusting rod 89. A lower end of the electric slid- ing block 5 is provided with the connecting hole 80 communicated with the arc-shaped groove, and a side wall of the connecting hole 80 is uniformly provided with the adjusting groove 81 along a cir- cumferential direction thereof. The lower end of the electric sliding block 5 is provided with an L-shaped slot arranged along the circumferential direction of the connecting hole 80. A side wall of the ball joint 6 is provided with the clamping slot 83 uniformly arranged along the circumferential direction of the con- necting hole 80. The L-shaped clamping strip 84 is mounted in the
L-shaped slot through the compression spring 82, a horizontal sec- tion of the L-shaped clamping strip 84 is located in the clamping slot 83, and a lower end of the L-shaped clamping strip 84 pene- trates through the T-shaped sliding slot 4. The lower end of the electric sliding block 5 is provided with an annular groove, the annular groove is located between the adjusting groove 81 and the
L-shaped slot, and a connecting ring is slidably connected in the annular groove. The hollow boss column 85 is mounted at a lower end of the connecting ring. A ball is rollingly connected to the lower end of the L-shaped clamping strip 84, and the ball rolling- ly abuts against an outer wall of the hollow boss column 85. The lifting rings 87 arranged in bilateral symmetry are mounted at the lower end of the electric sliding block 5. Supporting plates ar- ranged in bilateral symmetry are mounted on a side wall of the hollow boss column 85, and the ropes 86 are mounted on the sup- porting plates. The two ropes 86 respectively pass through the corresponding lifting rings 87, and lower ends of the two ropes 8¢ are connected through the pull rod 88. The adjusting rod 89 is mounted at a lower end of the ball joint €. A lower end of the ad-
Justing rod 89 passes through the connecting hole 80 and the hol- low boss column 85.
In operation, the support plate 1 is fixed at the edge of the crack of the tunnel through the suction fixing rod 2, whereby the gluing mechanism 3 is aligned with the crack of the tunnel. Then the electric sliding block 5 and the gluing mechanism 3 are simul- taneously started, whereby the electric sliding block 5 drives the gluing mechanism 3 to move along the crack, and glue is injected at the crack for leakage stoppage. When a branch crack is formed at the edge of the crack, the electric sliding block 5 stops mov- ing, the hollow boss column 85 is then driven to move up through the pull rod 88 and the rope 86, and the L-shaped clamping rod 84 is pushed to move towards the compression spring 82 while the hol- low boss column 85 moves up, whereby the compression spring 82 is contracted. At this moment, the L-shaped clamping rod 84 is moved out of the clamping slot 83, and then the adjusting rod 89 drives the gluing mechanism 3 above the ball joint 6 to rotate in the di- rection of the branch crack by means of the rotation of the ad-
Justing rod 89, whereby the glue injection pipe 31 on the gluing mechanism 3 and the preliminary shaping hot-pressing roller 34 ro- tate simultaneously, thereby preventing inversion of the working sequence thereof. When the gluing mechanism 3 is in parallel alignment with the branch crack, the ball joint 6 drives the glu- ing mechanism 3 to incline in the direction of the branch crack by means of the inclination of the adjusting rod 89. At this moment, the upper end of the inclined adjusting rod 89 inclines into the corresponding adjusting groove 81. The gluing mechanism 3 is al- ways in parallel alignment with the branch crack under the pushing of the supporting spring rod 7, and the glue is injected into the branch crack during the inclination of the gluing mechanism 3, thus also achieving the effect of gluing the branch crack for leakage stoppage. The adjusting mechanism 8 is convenient for the gluing mechanism 3 to inject the glue into the branch crack of the crack, so as to avoid the problem that gluing leakage stoppage for the branch crack at the edge of the crack cannot be achieved sim- ultaneously, without manual secondary gluing leakage stoppage.
Referring to FIGS. 6 and 7, a steering wheel is mounted at the lower end of the adjusting rod 89, direction rods 890 uniform- ly arranged along a circumferential direction of the steering wheel is mounted on an outer wall of the steering wheel, and the direction rods 890 are in one-to-one positional correspondence with the adjusting grooves 81.
In operation, the steering wheel and the direction rod 890 are convenient for the return and rotation of the adjusting rod 89 after driving the gluing mechanism 3 to glue the branch crack, whereby the clamping slot 83 on the ball joint 6 is aligned with the L-shaped slot when the direction rod 890 on the steering wheel is aligned with the adjusting groove 81 one by one. At this mo- ment, the L-shaped clamping rod 84 is easily clamped from the L- shaped slot into the clamping slot 83 to fix and limit the ball
Joint 6, thereby preventing the ball joint 6 from rotating freely.
Referring to FIG. 3, a square column 801 is mounted on an up- per end face of the front direction rod 890. The square column 801 facilitates determination of a moving direction of the glue injec- tion pipe 31 and prevents inversion of a working sequence of the glue injection pipe 31 and the preliminary shaping hot-pressing roller 34.
Referring to FIG. 2, the gluing mechanism 3 includes an arc- shaped seat 30, a glue injection pipe 31, a supporting seat 32, a [-shaped frame 33, a preliminary shaping hot-pressing roller 34, a
T-shaped hot-pressing plate 35, and fixed hot-pressing rollers 36.
The arc-shaped seat 30 is mounted at an upper end of the support- ing spring rod 7, the arc-shaped seat 30 is of an arc-shaped cavi- ty structure, and the glue injection pipe 31 is mounted in the arc-shaped seat 30. The supporting seat 32 is mounted in the arc- shaped seat 30, the supporting seat 32 is located on a left side of the glue injection pipe 31, and the [-shaped frame 33 with an upward opening is mounted on the supporting seat 32. The prelimi- nary shaping hot-pressing roller 34 is rotatably connected between front and rear end faces of the [-shaped frame 33. The T-shaped hot-pressing plate 35 is mounted on the supporting seat 32, an up- per end face of the T-shaped hot-pressing plate 35 is provided with a mounting groove, and the fixed hot-pressing rollers 36 ar- ranged equidistantly from left to right are rotatably connected in the mounting groove. The T-shaped hot-pressing plate 35, the [- shaped frame 33 and the glue injection pipe 31 are arranged suc- cessively from left to right.
Referring to FIG. 10, supporting rods arranged equidistantly from left to right are mounted in the mounting groove. The sup- porting rod is located on the right side of the fixed hot-pressing roller 36, a material removing plate 361 is mounted on the sup- porting rod through connecting rods arranged in front-rear sym- metry, and the material removing plate 361 is tightly attached to an outer wall of the left fixed hot-pressing roller 36.
In operation, the glue injection pipe 31 is connected to an external device to inject glue. While the electric sliding block 5 is started, the glue injection pipe 31 injects the glue, whereby the glue is injected into the crack. While the electric sliding block 5 moves, the preliminary shaping hot-pressing roller 34 on the left side of the glue injection pipe 31 flattens the injected glue. During the rolling, heat in the preliminary shaping hot- pressing roller 34 hydraulically shapes the glue, whereby the in- jected glue for leakage stoppage may be fast solidified prelimi- narily. After the preliminary shaping hot-pressing roller 34 rolls, the fixed hot-pressing roller 36 on the T-shaped hot- pressing plate 35 hot-rolls and fixes the glue, whereby the glue may be fast solidified and shaped under the effect of double hot- rolling, thereby achieving the effect of fast leakage stoppage, and preventing the glue from being washed away by water leaking due to the slow solidification of the glue after gluing. The mate- rial removing plate 361 scrapes the glue adhered on the outer wall of the fixed hot-pressing roller 36 while the fixed hot-pressing roller 36 rotates, and guides the scraped glue to the crack, thereby avoiding the problem of glue accumulation.
Referring to FIG. 2, left end faces of front and rear verti- cal sections of the [-shaped frame 33 are separately provided with a connecting plate, upper end faces of the connecting plates are
Jointly provided with a scraper 330, a right end face of the scraper 330 inclines to the lower right, and a right end of the scraper 330 is tightly attached to an outer wall of the prelimi- nary shaping hot-pressing roller 34.
In operation, the scraper 330 scrapes off the glue adhered on the outer wall of the preliminary shaping hot-pressing roller 34 while the preliminary shaping hot-pressing roller 34 rotates, so as to avoid the problem that the glue is adhered and accumulated on the outer wall of the preliminary shaping hot-pressing roller 34, thus making the preliminary shaping hot-pressing roller 34 difficult to roll the glue flat.
Referring to FIG. 2, a bracket is mounted on a right side wall of the glue injection pipe 31, and a flow guide plate 310 is mounted on the bracket through an abutting rod 312. A horizontal section of the flow guide plate 310 is hinged to an inclined sec- tion, the abutting rod 312 is connected to the inclined section of the flow guide plate 310, and an abutting spring is mounted be- tween the inclined section and the horizontal section of the flow guide plate 310. A left end of the flow guide plate 310 is close to the glue injection pipe 31, and the flow guide plate 310 is provided with flow guide slots 311 arranged equidistantly from front to rear.
In operation, before the glue injection pipe 31 glues the crack, the flow guide plate 310 guides the water leaking out of the crack, whereby the leaking water flows down with the flow guide slot 311 on the flow guide plate 310, so that the glue in- jection pipe 31 injects the glue into the crack.
In specific operation, the support plate 1 is first fixed at the edge of the crack of the tunnel through the suction fixing rod 2. At this moment, the suction cup on the suction fixing rod 2 tightly sucks together with the side wall of the tunnel so as to fixedly support the support plate 1. Next, the electric sliding block 5 and the external device are simultaneously started. The external device drives the glue injection pipe 31 to inject glue, whereby the glue is injected into the crack. While the electric sliding block 5 moves, the preliminary shaping hot-pressing roller
34 on the left side of the glue injection pipe 31 flattens the in- jected glue. During the rolling, the glue is hydraulically shaped by heat in the preliminary shaping hot-pressing roller 34. After the preliminary shaping hot-pressing roller 34 rolls, the fixed hot-pressing roller 36 on the T-shaped hot-pressing plate 35 hot- rolls and fixes the glue. When a branch crack is formed at the edge of the crack, the electric sliding block 5 stops moving, the hollow boss column 85 is driven to move up through the pull rod 88 and the rope 86, and then the adjusting rod 89 inclines, whereby the ball joint 6 drives the glue injection pipe 31 to incline in the direction of the branch crack. At this moment, the upper end of the inclined adjusting rod 89 inclines into the corresponding adjusting groove 81. The glue injection pipe 31 is always in par- allel alignment with the branch crack under the pushing of the supporting spring rod 7, and the glue is injected into the branch crack during the inclination of the glue injection pipe 31, thus also achieving the effect of gluing the branch crack for leakage stoppage.
In addition, it should be understood that while the specifi- cation has been described in terms of implementations, not every implementation includes an independent technical solution, such recitation of the specification is for purposes of clarity only, and those ordinarily skilled in the art will recognize that the specification serves as a whole and the technical solutions in various embodiments may be appropriately combined to form other implementations appreciated by those skilled in the art.
