The traditional pile head waterproofing structure is not easy to construct, and it is easy to disturb the sealing of the pile head waterproofing sealant during the reinforcement binding and concrete pouring of the basement floor slab, forming a leaking point, causing leakage, and becoming a weak point in the waterproofing system. In addition, the basement polymer self-adhesive pre-laid waterproof membrane is constructed by the empty laying method, which further increases the construction difficulty of the waterproofing structure at the pile head.

[0003] To solve the above problems, we made a series of improvements. Utility Model Content

[0012] The following is a further description of the present invention in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0013] Example 1

[0014] Figure 1 It is a structural schematic diagram of the utility model.

[0015] like Figure 1 As shown, a pile head waterproof structure includes: a self-adhesive pre-laid waterproof coiled material 100, a waterproof additional layer 200, a waterproof coating 300, a waterproof coiled material sealing paste 400, a stainless steel hoop 500, a cement mortar waterproof layer 600 and a pile main reinforcement sealing paste 700, the self-adhesive pre-laid waterproof coiled material 100 is arranged on a concrete cushion layer 800, the self-adhesive pre-laid waterproof coiled material 100 and the waterproof additional layer 200 are fixed to the pile head 900 through the stainless steel hoop 500, and the waterproof additional layer 200 is arranged on the self-adhesive pre-laid waterproof Within the range of 250mm of the roll material 100, the waterproof roll sealing paste 400 is arranged at the connection between the self-adhesive pre-laid waterproof roll material 100 and the waterproof additional layer 200 and the pile head 900, the waterproof coating 300 is arranged on the top and side of the pile head 900, the waterproof coating 300 is arranged on the concrete cushion layer 800 within the range of 250mm of the pile head 900, the cement mortar waterproof layer 600 is arranged above the waterproof coating 300, and the pile main reinforcement sealing paste 700 is arranged at the connection between the pile head 900 and the concrete pile main reinforcement 1000.

[0016] The implementation method of the utility model is that after the concrete pouring of the basement floor cushion layer is completed, the pile head 900 is 50mm higher than the cushion layer. Then, according to the structure designed by the utility model, a self-adhesive pre-laid waterproofing membrane 100 is laid on the concrete cushion layer 800, and then a waterproof coating 300 and a waterproof additional layer 200 are added within a range of 250mm around the pile head 900. The waterproof additional layer 200 is at the lower part of the self-adhesive pre-laid waterproofing membrane 100 and is bonded to the self-adhesive pre-laid waterproofing membrane 100. Next, a waterproofing membrane closing sealant 400 is pre-coated on the inner side of the bonding place between the pile head 900 and the waterproof additional layer 200 and the self-adhesive pre-laid waterproofing membrane 100, and the waterproof additional layer 200 and the self-adhesive pre-laid waterproofing membrane 100 are fixed around the pile head 900 with a stainless steel hoop 500, and the waterproofing membrane closing sealant 400 is used to seal the closing, and finally the pile main reinforcement sealing paste 700 is laid at the joint where the concrete pile main reinforcement 1000 is inserted into the pile head 900, and then the potting is completed.

[0017] The traditional waterproof structure adopts SBS waterproofing coil material, and the construction process adopts hot-melt construction. However, there are many defects. On the one hand, the construction is difficult, and the waterproof structure is easily damaged by hot-melt; on the other hand, it is difficult to handle the waterproof joint structure. Therefore, we want to use a flat waterproof coil, but if a flat waterproof coil is used, the problem will be as mentioned in the background technology, and its structural strength is seriously insufficient. Therefore, if you want to achieve this structure, the utility model has enhanced the structural strength. The waterproof coil at the pile head is fixed with a stainless steel hoop and sealed with a sealing paste, and an additional waterproof layer is added around the pile, and a penetrating crystallization waterproof coating waterproof layer is constructed within 250mm of the pile top and around the pile. A polymer waterproof cement mortar is added on the upper part of the coating waterproof layer to serve as a waterproof and protective layer to enhance the waterproof effect.

[0018] Compared with the traditional technology, the utility model adds a stainless steel hoop at the connection between the pile head and the waterproof coiled material to prevent the coiled material at the pile head from falling off during the process of binding the steel bars of the basement floor and pouring the concrete.

[0019] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
