Description

Technical Field

[0001] This invention relates to the field of shielding wall technology, specifically to a precast concrete shielding wall and its installation method. Background Technology

[0002] Radiation intensity decreases as it penetrates matter. Shielding materials of a certain thickness can reduce the intensity of radiation. By placing a sufficiently thick shield between the radiation source and the human body, the radiation level can be reduced, ensuring that the dose received by people at work is below the maximum permissible dose, thus guaranteeing personal safety and achieving the purpose of protection. The key to precast concrete shielding walls is to place a shielding material that can effectively absorb radiation between the radiation source and the human body, reducing the diffusion of radiation and the amount of radiation.

[0003] For example, Chinese Patent Publication No. CN111524625A describes a shielding wall, which aims to provide a shielding wall with adjustable protection strength. The key technical points of the solution are: it includes a shell, a sliding device at the bottom of the shell, and a shielding device on the shell.

[0011] A further improvement of the technical solution of the present invention is that: a snap-fit ​​groove is provided on the inner bottom of the L-shaped overlapping plate and at the left edge position; a mating hole is provided on the inner outer surface of the snap-fit ​​groove; one left end of the L-shaped unfolded overlapping plate is tightly fitted with the inner surface of the snap-fit ​​groove; and a threaded hole is provided on the inner top outer surface of the L-shaped overlapping plate.

[0012] A further improvement of the technical solution of the present invention is that: a C-shaped elastic strip is fixedly connected to the right outer surface of the bonding and fixing plate and located in the middle position; an upper and lower squeezing swing soft plate is fixedly connected to the right outer surface of the bonding and fixing plate and located at the upper and lower edges; and an anti-slip and wear-resistant texture is provided on one outer surface of the upper and lower squeezing swing soft plate.

[0013] A further improvement of the technical solution of the present invention is that: a pressure-resistant cement wall is fixedly connected to the inner and outer surfaces of the sealing cement protective layer on the left side; a wear-resistant and waterproof layer is provided on the inner and outer surfaces of the pressure-resistant cement wall; a pressure-resistant and wear-resistant layer is fixedly connected to the inner and outer surfaces of the wear-resistant and waterproof layer; a heat-resistant layer is fixedly connected to one outer surface of the pressure-resistant and wear-resistant layer; and one outer surface of the heat-resistant layer is tightly attached to the inner surface of the sealing cement protective layer on the right side.

[0014] A further improvement of the technical solution of the present invention is that: a compression deformation soft block is fixedly connected to the right outer surface of the wall panel overlap sealing mechanism, an overlap pushing plate is fixedly connected to one outer surface of the compression deformation soft block, the compression deformation soft block is evenly distributed on one outer surface of the L-shaped overlap platform and the overlap pushing plate, a sealing waterproof strip is fixedly connected to the inner side and near the top outer surface of the overlap pushing plate, and one outer surface of the sealing waterproof strip is fixedly connected to the right outer surface of the L-shaped overlap platform.

[0015] A further improvement of the technical solution of the present invention is that: a butt-joint aluminum alloy snap-fit ​​plate is movably overlapped on the outer surface of the front and rear sides of the concrete wall panel and on the outer surface of one side of the butt-joint groove; a threaded joint is provided on one side of the outer surface of the butt-joint aluminum alloy snap-fit ​​plate, and one end of the threaded joint passes through the surface of the butt-joint aluminum alloy snap-fit ​​plate and connects to one side of the outer surface of the concrete wall panel; the concrete is composed of cement, barite, sand, boron particles, crushed stone, admixture and water; the concrete formula, firstly, is arranged in the following order of weight components: cement 10%-15%, boron magnesium ore sand 10%-15%, sand 15%-20%, crushed stone 30%-45%, water 5%-7.5%, and water-reducing agent 0.25%-0.5%.

[0016] Secondly, a method for installing a precast concrete shielding wall, the method comprising the following steps:

[0017] Step 1: Install the L-shaped overlapping plate on the ground in a suitable position using the threaded holes. The L-shaped overlapping plate can be disassembled through the threaded holes later for easy replacement. Use the deformable flexible strip to swing the L-shaped unfolding overlapping plate and mate it with the inner surface of the locking groove. At the same time, use the mating recess to fix the L-shaped unfolding overlapping plate, reducing the possibility of loosening later and making it easy to disassemble the threaded holes for replacement of the L-shaped overlapping plate.

[0018] Step 2: When attaching the concrete wall panel to the inner surface of the L-shaped overlap plate, use the compression deformation soft block to push the overlap push plate, increasing the tightness between the overlap push plate and the surface of the concrete wall panel, increasing friction and sealing, reducing water from sliding off the surface of the concrete wall panel, and preventing water from seeping into the gap between the overlap push plate and the concrete wall panel. Finally, use a sealing waterproof strip to seal the top of the overlap push plate.

[0019] Step 3: When multiple concrete wall panels are joined together, the mating and fixing plates inside the mating grooves will fit together. When the surface of the mating and fixing plates is compressed, the up-and-down squeezing and swinging soft plate will be squeezed and deformed first to increase the compression area. The anti-slip and wear-resistant texture is used to increase the anti-slip properties, and the C-shaped elastic strip is used to increase the sealing between the two.

[0020] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0021] 1. This invention provides a precast concrete shielding wall and its installation method. The L-shaped overlapping plate is fixed in a suitable position by threading through the threaded hole. The L-shaped unfolding overlapping plate is swung with the help of the deformable soft strip. The L-shaped unfolding overlapping plate is mated with the inner surface of the snap-fit ​​groove. At the same time, the L-shaped unfolding overlapping plate is mated and fixed with the mating hole. This reduces the possibility of loosening later and also makes it easy to disassemble the threaded hole to replace the L-shaped overlapping plate.

[0022] 2. This invention provides a precast concrete shielding wall and its installation method. When the L-shaped unfolded lap plate is joined, the sealing plate on one side of the outer surface of the lap plate is attached to the surface of the threaded hole to seal the entrance of the hole, reducing the corrosion of the inside of the threaded hole by water source in the later stage, and facilitating the replacement in the later stage.

[0023] 3. This invention provides a precast concrete shielding wall and its installation method. When the concrete wall panel is snapped onto the inner surface of the L-shaped overlapping platform, the overlapping pushing plate is pushed by the extrusion deformation soft block to increase the tight fit between the overlapping pushing plate and the surface of the concrete wall panel, increase the friction and sealing, reduce the water from sliding off the surface of the concrete wall panel, and at the same time, prevent water from seeping into the gap between the overlapping pushing plate and the concrete wall panel. Finally, the top of the overlapping pushing plate is overlapped and sealed by a sealing waterproof strip.

[0024] 4. This invention provides a precast concrete shielding wall and its installation method. When the concrete wall panels are joined together, the mating and fixing plates inside the mating groove will be mated together. When the surface of the mating and fixing plates is squeezed, the up-and-down squeezing and swinging soft plate will be squeezed and deformed first to increase the squeezing area. The anti-slip and wear-resistant texture is used to increase the anti-slip property, and the C-shaped elastic strip is used to increase the sealing property between the two.

[0037] The present invention will be further described in detail below with reference to embodiments:

[0038] Example 1

[0039] Firstly, such as Figure 1-6As shown, this invention provides a precast concrete shielding wall and its installation method, including a precast concrete shielding wall 1, which includes a concrete wall panel 2. The concrete wall panel 2 includes a sealing cement protective layer 21. A butt joint groove 3 is formed on the outer surfaces of the front and rear sides of the concrete wall panel 2 at the edges. A sealing and wear-resistant fitting mechanism 4 is fixedly connected to the inner outer surface of the butt joint groove 3. The sealing and wear-resistant fitting mechanism 4 includes a fitting and fixing plate 41. A wall panel overlap sealing mechanism 7 is provided on the bottom outer surface of the concrete wall panel 2 at the edge. The overlapping sealing mechanism 7 includes an L-shaped overlapping platform 71. A mating aluminum alloy snap-fit ​​plate 5 is movably overlapped on the outer surfaces of the front and rear sides of the concrete wall panel 2, specifically on one side of the mating groove 3. A threaded connector 6 is provided on one side of the outer surface of the mating aluminum alloy snap-fit ​​plate 5, with one end of the threaded connector 6 passing through the surface of the mating aluminum alloy snap-fit ​​plate 5 and connecting to one side of the outer surface of the concrete wall panel 2. A deformable flexible strip 72 is fixedly connected to the inner side of the L-shaped overlapping platform 71, specifically on the top outer surface. An L-shaped unfolding overlapping plate 73 is fixedly connected to one side of the outer surface of the deformable flexible strip 72. A butt joint rod is provided on the inner side of plate 73 near the left inner surface. A rectangular hollow elastic strip 74 is fixedly connected to the lower surface of the L-shaped unfolded overlapping plate 73. An overlapping plate 75 is fixedly connected to one outer surface of the rectangular hollow elastic strip 74. A sealing plate 76 is fixedly connected to the bottom outer surface of the overlapping plate 75. A snap-fit ​​groove 78 is provided on the inner bottom of the L-shaped overlapping plate 71 near the left edge. A butt joint recess 79 is provided on the inner outer surface of the snap-fit ​​groove 78. The left end of the L-shaped unfolded overlapping plate 73 is tightly fitted to the inner surface of the snap-fit ​​groove 78. A threaded hole 77 is provided on the inner top outer surface of the L-shaped overlapping platform 71. A compression deformation soft block 710 is fixedly connected to the right outer surface of the wall panel overlapping sealing mechanism 7. An overlapping push plate 711 is fixedly connected to one outer surface of the compression deformation soft block 710. The compression deformation soft blocks 710 are evenly distributed on one outer surface of the L-shaped overlapping platform 71 and the overlapping push plate 711. A sealing waterproof strip 712 is fixedly connected to the inner side and near the top outer surface of the overlapping push plate 711. One outer surface of the sealing waterproof strip 712 is fixedly connected to the right outer surface of the L-shaped overlapping platform 71.

[0040] Furthermore, the L-shaped overlapping plate 71 is threaded into a suitable position through the threaded hole 77. The L-shaped unfolding overlapping plate 73 is oscillated using the deformable flexible strip 72. When the L-shaped unfolding overlapping plate 73 is mated, the sealing plate 76 on one outer surface of the overlapping plate 75 adheres to the surface of the threaded hole 77, sealing the entrance to the hole and reducing the risk of water erosion of the threaded hole 77, thus facilitating future replacement. The L-shaped unfolding overlapping plate 73 also mates with the inner surface of the snap-fit ​​groove 78, and is simultaneously fixed in place by the mating recess 79, reducing... The less likely it is to loosen later, it is also convenient to disassemble the threaded hole 77 to replace the L-shaped overlapping plate 71. When the concrete wall panel 2 is snapped onto the inner surface of the L-shaped overlapping plate 71, the overlapping pushing plate 711 is pushed with the extrusion deformation soft block 710 to increase the tight fit between the overlapping pushing plate 711 and the surface of the concrete wall panel 2, increase the friction and sealing, reduce the water from sliding on the surface of the concrete wall panel 2, and at the same time, it helps to prevent water from seeping into the gap between the overlapping pushing plate 711 and the concrete wall panel 2. Then, the top of the overlapping pushing plate 711 is overlapped and sealed with the sealing waterproof strip 712.

[0041] Example 2

[0042] like Figure 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a C-shaped elastic strip 42 is fixedly connected to the right outer surface of the fitting and fixing plate 41 and located in the middle position, and an upper and lower squeezing swing soft plate 43 is fixedly connected to the right outer surface of the fitting and fixing plate 41 and located at the upper and lower edges. An anti-slip and wear-resistant texture 44 is provided on one outer surface of the upper and lower squeezing swing soft plate 43. When the concrete wall panel 2 is joined, the fitting and fixing plate 41 inside the mating groove 3 will be joined and mated. When the surface of the fitting and fixing plate 41 is squeezed again, the upper and lower squeezing swing soft plate 43 will be squeezed and deformed first to increase the squeezing area. The anti-slip property is increased by the anti-slip and wear-resistant texture 44, and the sealing property between the two is increased by the C-shaped elastic strip 42.

[0043] Example 3

[0044] like Figure 1-6As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a pressure-resistant cement wall 22 is fixedly connected to the inner outer surface of the left sealing cement protective layer 21, a wear-resistant and waterproof layer 23 is provided on the inner outer surface of the pressure-resistant cement wall 22, a pressure-resistant and wear-resistant layer 24 is fixedly connected to the inner outer surface of the wear-resistant and waterproof layer 23, a heat-resistant layer 25 is fixedly connected to one outer surface of the pressure-resistant and wear-resistant layer 24, and one outer surface of the heat-resistant layer 25 is tightly attached to the inner surface of the right sealing cement protective layer 21. This works in conjunction with the sealing cement protective layer 21 to protect against external forces, and with the pressure-resistant cement wall 22 and the pressure-resistant and wear-resistant layer 24 to resist external pressure. Simultaneously, the heat-resistant layer 25 and the wear-resistant and waterproof layer 23 provide insulation and protection against external high temperatures and water sources.

[0045] Example 4

[0046] Secondly, such as Figure 1-6 As shown, the present invention provides a method for installing a precast concrete shielding wall, which includes the following steps:

[0047] Step 1: Install the L-shaped overlapping plate 71 on the ground in a suitable position using the threaded hole 77. The L-shaped overlapping plate 71 can be disassembled through the threaded hole 77 later for easy replacement. Use the deformable flexible strip 72 to swing the L-shaped unfolding overlapping plate 73, and mate the L-shaped unfolding overlapping plate 73 with the inner surface of the snap-fit ​​groove 78. At the same time, use the mating recess 79 to mate and fix the L-shaped unfolding overlapping plate 73, reducing the possibility of loosening later and making it easy to disassemble the threaded hole 77 to replace the L-shaped overlapping plate 71.

[0048] Step 2: When attaching the concrete wall panel 2 to the inner surface of the L-shaped overlapping platform 71, the overlapping pushing plate 711 is pushed by the extrusion deformation soft block 710 to increase the tight fit between the overlapping pushing plate 711 and the surface of the concrete wall panel 2, increase friction and sealing, and reduce water from sliding off the surface of the concrete wall panel 2. At the same time, it helps to prevent water from seeping into the gap between the overlapping pushing plate 711 and the concrete wall panel 2. Finally, the top of the overlapping pushing plate 711 is overlapped and sealed by the sealing waterproof strip 712.

[0049] Step 3: When multiple concrete wall panels 2 are joined together, the mating and fixing plates 41 inside the mating groove 3 will be mated together. When the surface of the mating and fixing plate 41 is squeezed, the up-and-down squeezing and swinging soft plate 43 will be squeezed and deformed first to increase the squeezing area. The anti-slip and wear-resistant texture 44 is used to increase the anti-slip property, and the C-shaped elastic strip 42 is used to increase the sealing property between the two.

[0050] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
