Description

Technical Field

[0001] The invention relates to the field of anti-seepage wall construction, in particular to a concrete anti-seepage wall joint pipe construction method and hoisting equipment thereof. Background Art

[0002] In the construction of concrete anti-seepage walls, the construction process of joint pipes plays a vital role in ensuring the continuity and anti-seepage performance of the wall. The existing process requires that before pouring the concrete of the first-phase slot section, a professional lifting device is required to vertically and accurately lift the joint pipe into the predetermined position of the slot hole to ensure that the pipe body is stable and has good sealing. When the concrete enters a reasonable period from initial setting to final setting, the lifting equipment is used to grade and slowly lift the joint pipe according to the established procedures. The lifting force must be uniform and stable to separate the joint pipe from the concrete and form a regular semicircular joint hole. During the construction of the second-phase slot section, the newly poured concrete can be closely connected to the joint hole to achieve the continuity and anti-seepage effect of the anti-seepage wall.

[0003] However, the current joint pipe technology has significant defects. When traditional rigid joint pipes are constructed in large and deep holes, a large number of pipe segments are required, and the connection and installation of the pipe segments are extremely complicated and difficult to splice, which seriously affects the sealing and stability. After the joint pipe is set down, it is easy to tilt due to various factors, and it may even be unable to reach the bottom of the slot. In the pipe pulling link, the control of the pulling time becomes a key problem. If the pulling is too early, the concrete will not reach the self-supporting strength, and the wall of the joint hole will easily shrink and collapse, resulting in construction failure; if the pulling is too late, the concrete will harden and adhere to the joint pipe, and the friction will increase dramatically, far exceeding the traction force of the pulling equipment. In extreme cases, the joint pipe will be "cast" in the concrete, causing serious construction accidents, delays in construction period, economic losses, and endangering the overall safety of the project.

[0004] At present, Chinese patent CN218843169U discloses a rubber inflatable anti-seepage wall joint pipe, which uses an inflatable rubber bladder to replace the joint pipe, making it easy to set up and pull out, and it can be reused. At the same time, it is not easy to cause quality accidents due to poor grasp of the pulling out time. Then, during use, its pressure stability is difficult to guarantee, and the construction needs to continuously and accurately monitor and adjust the inflation pressure in time, which is cumbersome. Moreover, due to its large buoyancy, the construction operation is more difficult, and higher requirements are put forward for the construction process and process, which limits its wide application in actual engineering. Therefore, a concrete anti-seepage wall joint pipe construction method and its hoisting equipment are proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0018] Example 1 like Figure 1-5 As shown, it includes a high-pressure flat hose 1, and a pipe opening 2 is provided at the top of the high-pressure flat hose 1; The method includes: S1. A counterweight 6 is sealed at the bottom of the high-pressure flat hose 1. The counterweight 6 is a high-density fine-grained solid material, such as sand, and is sealed at the bottom of the high-pressure flat hose 1 through a sealing method, such as resin infusion sealing. The counterweight 6 is used to offset the buoyancy of the hose during the lowering and water filling process to ensure that the hose sinks smoothly to a predetermined depth. Then, a net bag 4 is set on the outside of the bottom of the high-pressure flat hose 1. The net bag 4 is a wire net bag. The net bag is woven with high-strength corrosion-resistant steel wire. The mesh is fine and dense, which holds and protects the hose to prevent the hose from being damaged by tension. A plurality of pull ropes 5 are fixed on the net bag. The pull ropes 5 are four steel wire ropes. One end of the pull ropes is connected to the steel wire net bag at multiple points through a fastening clamp, and the other end extends along the hose wall to the ground operation end.

[0019] S2. Place the high-pressure flat hose 1 vertically into the anti-seepage wall slot 100 through the lifting equipment 7. Pay close attention to the stress state of the pull rope 5 and the verticality of the high-pressure flat hose 1 during the process. It should be noted that before the high-pressure flat hose 1 is lowered, a release agent needs to be applied on its outer surface, the wire rope and the net bag 4. After it is lowered into place, lift it up so that the bottom is suspended in the air, with a specific height of no more than 100 cm. Let it stand for a while to make it vertical and then sink to the bottom to ensure its vertical state.

[0020] S3. Pour water into the high-pressure flat hose 1 through the pipe mouth 2 until it is full, then close the pipe mouth 2, and set a pressurizing device at the pipe mouth 2. Through the pressure supplementation of the pressurizing device, the pressure is balanced with the confining pressure generated by the concrete and mud outside the pipe. It should be noted that the spacing relationship between the pull ropes 5 can meet the requirement that it is tightly attached to the outside of the high-pressure flat hose 1 after water injection and expansion, so as to avoid excessive extension and burial in the concrete of the anti-seepage wall.

[0021] Through the above steps, a joint pipe is formed in the cut-off wall slot 100 .

[0022] S4. After the concrete outside the pipe is poured to the top and exceeds the final setting time of the concrete, the pipe mouth 2 is opened, the water in the high-pressure flat hose 1 is drained, and then the pipe mouth 2 is closed.

[0023] S5. Then, the high-pressure flat hose 1 is evacuated by an exhaust device to make the inside of the hose reach a vacuum state, thereby utilizing the negative pressure principle to facilitate the hose to be smoothly separated from the concrete.

[0024] S6. Finally, the high-pressure flat hose 1 is lifted out of the anti-seepage wall slot 100 by the hoisting equipment 7.

[0025] With this design, the problem of the inability to maintain pressure stability and large buoyancy of the rubber inflatable anti-seepage wall joint pipe can be effectively solved by injecting water into the high-pressure flat hose 1 to seal it instead of expanding it with air pressure. At the same time, compared with the traditional extra-large diameter joint pipe, the structure is simplified and easy to plug and unplug. When not expanded, it can shrink softly, fold and curl at will. After expansion, it has sufficient strength to withstand the pressure of concrete.

[0026] Compared with the inflatable joint pipe, the incompressibility of water makes it relatively easier to control the pressure of the joint pipe after water injection, and water will not easily produce large volume fluctuations due to pressure changes like gas within a certain range. There is no need to monitor and adjust the pressure as frequently as inflation, which reduces the complexity and difficulty of operation, can more stably play the role of the joint pipe, and reduce construction problems caused by unstable pressure. At the same time, since the density of water is greater than that of air, the overall weight of the joint pipe increases relatively after water injection, which can effectively reduce the construction inconvenience caused by large buoyancy, and make the position of the joint pipe in the slot more stable, which is conducive to ensuring construction quality and reducing the position deviation of the joint pipe or difficulty in accurately lowering it to the bottom due to buoyancy problems.

[0027] In this embodiment, the high-pressure flat hose 1 is based on woven fibers such as polyester and aramid as the main structure, and the composite thermoplastic elastomer is tightly compounded on the inner and outer sides of the woven fibers to serve as the inner lining and outer lining respectively. During the manufacturing process, fibers such as polyester and aramid are first interwoven into the skeleton structure of the hose. The structure, by virtue of the high strength and high toughness of the woven fibers themselves, gives the hose basic compression and tensile properties. Subsequently, the composite thermoplastic elastomer is evenly and firmly attached to the inner and outer surfaces of the woven fibers. The composite thermoplastic elastomer has excellent flexibility, sealing and certain wear resistance, and cooperates with the woven fibers, so that the high-pressure flat hose 1 has multiple advantages of being soft and bendable, wear-resistant and resistant to high pressure, so that the high-pressure flat hose 1 can operate stably in a complex and harsh working environment, and the diameter of the high-pressure flat hose 1 is the same as the thickness of the anti-seepage wall, the wall thickness is 3mm-5mm, and the tube length is slightly greater than the depth of the anti-seepage wall slot 100.

[0028] In the preferred embodiment, a closable valve hole 3 is provided above the high-pressure flat hose 1, so as to facilitate the connection of a pressurizing device or a vacuum device when the pipe mouth 2 is sealed, thereby avoiding the direct connection of a pressurizing device or a vacuum device to the pipe mouth 2, which would cause the pipe mouth 2 to be unable to be completely sealed.

[0029] In the preferred embodiment, a sealing component 8 for sealing the pipe mouth 2 is also included, which includes a sealing rubber plate 801 that can be placed in the pipe mouth 2, and two clamps 802 that support the pipe mouth 2 from the outside. The length of the sealing rubber plate 801 is adapted to the length of the pipe mouth 2 in a flat state, so that the sealing rubber plate 801 can be placed in the pipe mouth 2. The sealing rubber plate 801 and the tops of the two clamps 802 are provided with corresponding multiple connecting seats 804, and top bolts and nuts 805 are provided between the corresponding connecting seats 804. The two clamps 802 and the sealing rubber plate 801 are connected by the top bolts and nuts 805, and the two clamps 802 clamp the sealing rubber plate 801 by tightening the nuts to achieve the effect of closing the pipe mouth 2. End bolts and nuts 806 located at both ends of the two clamps 802 are also provided between the two clamps 802 to further improve the locking force. Holes for bolts to pass through are provided on the ends of the clamps 802 and the connecting seats 804.

[0030] The opposite sides of the two clamping plates 802 are provided with clamping sealing strips 803 , and the sealing performance is improved by the extrusion deformation when the clamping sealing strips 803 and the sealing rubber plate 801 are locked.

[0031] Both sides of the sealing rubber plate 801 are provided with embedded grooves 807 corresponding to the clamping sealing strip 803, so that the clamping sealing strip 803 can be embedded in the embedded grooves 807, thereby further improving the sealing performance.

[0032] Example 2 Further illustrate with reference to Example 1, Figure 6-13In order to facilitate the implementation of the above construction method, in this embodiment, a lifting device is also proposed for lifting the flat hose 1, including a walking trolley 71 that can travel on both sides of the anti-seepage wall slot 100. The walking trolley 71 can be moved in a track-type or tire-type manner to move to the installation position of the joint pipe. A frame-type transverse moving vehicle 72 is movably installed on the walking trolley 71 through a transverse track. The frame-type transverse moving vehicle 72 can be transversely moved on the walking trolley 71, so as to facilitate transverse movement to the top of the anti-seepage wall slot 100. The frame-type transverse moving vehicle 72 is provided with a device for retracting and releasing the flat hose. The winding mechanism 73 of the hose 1 is provided with a connecting rope 9 on the top of the flattened hose 1 for winding and releasing. The connecting rope 9 is a steel wire rope, one end of which is fixed on the top of the flattened hose 1, and the other end is fixed on the winding mechanism 73, so that after the flattened hose 1 is completely lowered, it can still maintain connection with the winding mechanism 73. A support platform 74 is also provided on the top of the frame-type transverse shift vehicle 72, and a rope winding and releasing mechanism 75 for winding and releasing the rope 5 is provided on the support platform 74. Through the cooperation of the winding mechanism 73 and the rope winding and releasing mechanism 75, the flattened hose 1 can be stably wound and released, and a lifting effect with multi-point force can be achieved at the same time.

[0033] In the preferred embodiment, the winding mechanism 73 includes two bearing seats 730 symmetrically arranged on the frame-type transverse shift vehicle 72, and a rotating shaft 731 is rotatably arranged between the two bearing seats 730 through an internally arranged bearing. A winding drum 732 is arranged on the outside of the rotating shaft 731, and the end of the connecting rope 9 is fixed on the winding drum 732. The retraction and release of the compressed flat hose 1 is achieved by the forward or reverse rotation of the winding drum 732.

[0034] In the preferred embodiment, the pull rope retracting and releasing mechanism 75 includes an extension platform 757 arranged on the side of the support platform 74, and a retracting and releasing assembly is arranged on the top of the extension platform 757. The openings 750 on the top plate of the support platform 74, and the number and positions of the openings 750 correspond to the pull rope 5, specifically four, and a guide wheel 751 is arranged above the opening 750. The pull rope 5 passes through the opening 750 and the guide wheel 751 and is connected to the retracting and releasing assembly, and then the pull rope 5 is retracted and released by the forward or reverse rotation of the retracting and releasing assembly.

[0035] Among them, the retracting and releasing assembly includes two columns 752 symmetrically arranged on the top of the extension platform 757, two rotating rods 753 are rotatably arranged between the two columns 752, and a total of retracting and releasing cylinders 754, the same number as the pull rope 5, are arranged on the two rotating rods 753, specifically four, two in a group, and the two groups of retracting and releasing cylinders 754 are respectively arranged on the two rotating rods 753, and the pull rope 5 is connected to the corresponding retracting and releasing cylinders 754. One end of the two rotating rods 753 passes through the column 752 and is connected to a linkage gear 755. The side of the column 752 is rotatably provided with an idle gear 756 that is simultaneously meshed with the two linkage gears 755, so that the two rotating rods 753 can rotate in the same direction through the transmission of the idle gear 756, thereby realizing the synchronous retraction and release of the four pull ropes 5.

[0036] In the preferred embodiment, a driving mechanism 76 is also included for simultaneously driving the reeling mechanism 73 and the pull-cord retracting and releasing mechanism 75, thereby ensuring that the reeling mechanism 73 and the pull-cord retracting and releasing mechanism 75 are retracted and released synchronously. It should be noted that the reserved length of the pull-cord 5 is adapted to the retracting and releasing length of the flattened hose 1 to avoid a one-in-one-back situation, which causes the flattened hose 1 to be unable to be lowered vertically or reeled smoothly.

[0037] The driving mechanism 76 includes a first driving device 760 arranged on the top of the support platform 74, and a transmission sprocket 761 is arranged at the output end of the first driving device 760. The end of the rotating shaft 731 passes through the bearing seat 730 and is provided with two synchronous sprockets 762. A driven sprocket 764 is arranged at the end of one of the rotating rods 753. A transmission chain 763 is installed between the driving sprocket 761 and one of the synchronous sprockets 762, and between the driven sprocket 764 and the other synchronous sprocket 762, thereby achieving the effect of simultaneously driving the winding mechanism 73 and the rope retracting mechanism 75.

[0038] Such a design can avoid uneven force on the pull rope 5 and the flattened hose 1 due to uneven speeds during the lowering or recovery process.

[0039] In the preferred embodiment, a cleaning device 77 is also included for cleaning the high-pressure flat hose 1 during the recycling process.

[0040] The cleaning device 77 includes two water spray assemblies 771 and a rotating cleaning mechanism 772 symmetrically arranged on both sides of the high-pressure flat hose 1, and a pushing telescopic cylinder 773 for controlling the distance between the two rotating cleaning mechanisms 772. One end of the pushing telescopic cylinder 773 is hinged on the frame-type transverse shift vehicle 72, and the other end is hinged to one of the rotating cleaning mechanisms 772. The two rotating cleaning mechanisms 772 are transmission connected, so that the water spray assembly 771 is used to spray water to clean the two sides of the flat state of the high-pressure flat hose 1, and the rotating cleaning mechanism 772 performs rotational cleaning on both sides.

[0041] It should be noted that the rotating cleaning mechanism 772 is specifically arranged between the high-pressure flat hose 1 in a flat state and the pull rope 5.

[0042] The water spray assembly 771 includes two suspension rods 7710 arranged at the bottom of the top plate of the support platform 74, a water supply pipe 7711 is arranged between the two suspension rods 7710, a plurality of high-pressure nozzles 7712 are arranged on the side of the water supply pipe 7711 close to the high-pressure flat hose 1, and the water inlet end of the water supply pipe 7711 is connected to a water supply device.

[0043] The rotary cleaning mechanism 772 includes a rotating seat 7721 symmetrically arranged on both sides of the frame-type transverse moving vehicle 72, the rotating seat 7721 is rotatably arranged on the side of the frame-type transverse moving vehicle 72 through a rotating shaft 7720, and the rotating shaft 7720 is rotatably arranged on the side of the frame-type transverse moving vehicle 72 through a bearing, and a rotating rod 7723 is rotatably arranged between the two rotating seats 7721, and a rotating brush 7724 is arranged on the outside of the rotating rod 7723, and a support plate 7725 is arranged on the outside of one of the rotating seats 7721, and a The second driving device 7726, the output shaft of the second driving device 7726 is connected to the rotating rod 7723, so that the rotating rod 7723 and the rotating brush 7724 are driven to rotate by the power of the second driving device 7726, and then the cleaning effect is achieved through the contact between the rotating brush 7724 and the surface of the high-pressure flat hose 1. At the same time, the rotating cleaning mechanism 772 can adjust its contact distance with the high-pressure flat hose 1 by rotating through the rotating shaft 7720, which can ensure close cleaning and also achieve separation to prevent affecting the lowering of the high-pressure flat hose 1.

[0044] A transmission gear 7722 is also provided on the outside of the rotating rod 7723, and the transmission gears 7722 of the two rotating cleaning mechanisms 772 are meshed with each other. Therefore, when the telescopic cylinder 773 is telescopically pushed to adjust the positional relationship between one of the rotating cleaning mechanisms 772 and the high-pressure flat hose 1, the other rotating cleaning mechanism 772 can be adjusted synchronously.
