[0016] The following will be combined with specific embodiments and appendix Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the present utility model.
[0017] A device for auxiliary construction of anti-seepage at the root of a pipe, including a template for forming a floor slab, the template is used to assist in pouring concrete to form a floor slab separating floors, and also includes an open mold 1, the open mold 1 is shaped like a bowl, and its side is a tapered surface, which is larger at the top and smaller at the bottom. The height of the open mold 1 is greater than or equal to the thickness of the floor slab, so that after the open mold 1 is set, a truncated cone-shaped hole with a larger top and a smaller bottom can be formed on the surface where the concrete is located when pouring concrete, so as to be used for the placement of a sewer pipe 2. The opening of the open mold 1 is upward, and it has a bottom and an open top. Two through holes are provided on the bottom end surface of the open mold 1, and connecting rods 11 are provided in both through holes. The connecting rods 11 are L-shaped. The lower end of the connecting rod 11 is fixed to the template, and the upper end of the connecting rod 11 is arranged in the vertical direction. A thread is provided at the upper end of the connecting rod 11, and each connecting rod 11 is threadedly connected to a limiting bolt 12. The limiting bolt 12 is detachable. The two connecting rods 11 are arranged corresponding to the two through holes on the bottom end surface of the open mold 1. The open mold 1 can be passed through the connecting rod 11, and then the open mold 1 can be firmly fixed to the connecting rod 11 by tightening the limiting bolt 12, so that the open mold 1 is fixedly connected to the template. When pouring concrete, the open mold 1 can discharge the concrete, forming a truncated cone-shaped hole with a larger top and a smaller bottom here for placing the pipe 2.
[0018] Several protrusions 13 are provided on the outer surface of the open mold 1. The protrusions 13 are made of rubber and are fixed by plugging into holes opened on the side of the open mold 1. The protrusions 13 can undergo elastic deformation. The elastic deformation makes it easier to demold the open mold 1, and it will not be blocked by the protrusions 13. The several holes and grooves formed by the protrusions 13 can ensure the bonding strength between the secondary pouring mortar and the already formed concrete. A protective cover 14 is assembled and connected to the top of the open mold 1. The protective cover 14 is fixedly connected to the handle. The assembly and use of the protective cover 14 can prevent concrete from flowing into the open mold 1 during the pouring of the floor concrete and affecting the mold opening.
[0019] The open mold 1 needs to be removed after the first concrete pouring and solidification, and then the pipe 2 can be installed. After the pipe 2 is installed, the space between the pipe 2 and the concrete floor slab 21 needs to be filled and sealed to perform sufficient waterproofing. This process requires the assistance of a filling device 3 for filling. The filling device 3 includes a wooden formwork 31, a formwork fixing card 32, a connecting line 33 and a fixing bracket 34. The wooden formwork 31 is sleeved and connected to the pipe 2, and the wooden formwork 31 needs to be sleeved and connected to the pipe 2 below the floor slab. The wooden formwork 31 is fixedly connected with a connecting line 33, which passes through the channel formed by the open mold 1 and is connected to the formwork fixing card 32. The formwork fixing card 32 is annular and is sleeved on the pipe 2 above the floor slab. The upper part of the formwork fixing card 32 is assembled and connected to the fixing bracket 34, and the fixing bracket 34 provides an upward support force, so that the formwork fixing card 32 can lift and support the wooden formwork 31, so that the wooden formwork 31 can be in the second Maintain firm support performance during the pouring of concrete, and then pour waterproof mortar in the channel formed in the open mold 1 twice. Pour two-fifths for the first time, store water after final setting to check for leakage, then wrap the expansion water stop strip around the pipe 2, and bond the joints with special glue to ensure the fit between the expansion water stop strip and the pipe 2. Complete the remaining cement mortar pouring, and then you can cut the connecting line 33 into sections, disassemble the wooden formwork 31, formwork fixing card 32 and fixing bracket 34 for reuse. A formwork fixing card 32 is also provided under the wooden formwork 31. It is located under the wooden formwork 31 and plays a supporting role to enhance the support stability of the wooden formwork 31.
[0020] The cam 342 is provided with a plurality of fixed grooves 343 at equal intervals on the cam 342, and each of the plurality of fixed grooves 343 is slidably connected to a support block 344. The support block 344 can be slidably adjusted to any one of the fixed grooves 343, and the fixed grooves 343 can play a strong supporting and fixing role for the support block 344. A support rod 345 is rotatably connected to the support block 344, and a U-shaped card is provided on the top of the support rod 345, which can be fixedly clamped on the template fixing card 32. The U-shaped card is a prior art. The support rod 345 supports the template fixing card 32 upward with the fixed base 341 as support. The template fixing card 32 tightly pulls the wooden template 31, and the blocking template does not need to be supported from the full length, saving support materials, convenient construction, and material saving, and is firmly fixed and has a good molding effect. By combining the filling device 3 with the secondary pouring process, strict waterproofing construction can be carried out around the pipeline 2, thereby effectively preventing leakage problems at the root of the pipeline 2 during use.
