Problems solved by technology

[0006] However, there are still some problems in the implementation of the above method: 1. The adhesion between the waterproof membrane and the contact object is relatively poor, and the waterproof performance is average; 2. The waterproof membrane used is relatively high, and the labor cost is relatively high. High, and the construction cost is relatively high; 3. During construction, the requirements for the base layer are high, which increases the construction period and greatly affects the construction progress

Embodiment 1

[0028] In this embodiment, the construction method of pre-laying anti-adhesive composite polymer waterproof membrane on pile raft foundation, the construction method includes the following steps:

[0029] (1) Cushion construction: according to the design requirements, the concrete pouring construction of the cushion is carried out, and a 145-155mm thick C20 concrete cushion is poured;

[0030] (2) Cleaning of the base layer and positioning of the wires: remove dust and oil on the surface of the base layer to ensure that the base layer is solid, flat and free of debris; then, the control line for laying the coiled material is released on the base layer to avoid misalignment, skew, etc.

[0031] (3) Treatment of the details of deformation joints and yin and yang corners: set up an additional layer of coiled material at the junction of plane and vertical surfaces, deformation joints, construction joints, and pipe roots, and cut them on site according to requirements. The addition...

Embodiment 2

[0039] The Chengxing complex project consists of Chengxing Garden, Chengxing Plaza and Chengxing Building, with a total construction area of ​​435,000㎡, of which the floor area of ​​the basement is about 23,000㎡ for Chengxing Garden, and about 13,000㎡ for Chengxing Plaza. 10,000 ㎡, Chengxing Building: about 14,000 ㎡, a total of about 50,000 ㎡; the design requirements for the original waterproof layer of the basement floor are:

[0040] 150mm thick C20 concrete cushion

[0041] 3mm thick polyester tire SBS modified bitumen waterproof membrane two layers

[0042] 50 thick C20 fine stone concrete leveling layer

[0043] Cast-in-place reinforced concrete floor

[0044] In this embodiment, according to the construction method of pre-laying anti-adhesive composite polymer waterproof coiled material on the pile raft foundation of the present invention, the design requirements for the waterproof layer of the basement floor are changed to:

[0045] 150mm thick C20 concrete cushion ...

Embodiment 3

[0053] This embodiment is illustrated by engineering examples. This construction method has been successfully applied in three engineering projects, Chengxing Garden, Chengxing Plaza, and Chengxing Building, Jiangyin Chengxing Complex in Wuxi City. This project is located on the east side of Huashan Road in Jiangyin City. On the south side of Qianlu Road, the total construction area is about 435,000 square meters, of which Chengxing Garden has a construction area of ​​about 200,000 square meters. A total of 6 buildings are residential projects. It is 33-34 floors; Chengxing Plaza has a construction area of ​​about 85,000 square meters, with three floors underground and seven floors above ground; Chengxing Building has a construction area of ​​about 200,000 square meters, three floors underground, 50 floors above ground, and four floors in the podium. At present, Chengxing Garden has entered the decoration construction stage, Chengxing Plaza has been constructed to the fourth fl...

Abstract

The invention relates to a construction method for pre-paving and inverted bonding of a composite macromolecule waterproof roll on a piled raft foundation. The construction method comprises the first step of cushion layer construction, the second step of base layer cleaning and paying-off positioning, the third step of deformation joint and female and male corner fine part treatment, the fourth step of large-area waterproof roll paving and attaching, the fifth step of protection film removing, the sixth step of waterproof protection layer construction and the seventh step of reinforced concrete construction. The construction method for pre-paving and inverted bonding of the composite macromolecule waterproof roll on the piled raft foundation has the beneficial effects that according to the composite macromolecule waterproof roll pre-paving and inverted bonding construction technology, a non-bonding face is emptily laid on a foundation cushion layer, a bonding face is upwards combined with a cast-in-place concrete face into a whole, and water moving hidden danger is avoided in the middle; even part of the roll is damaged, water is limited in a very small range due to the reliable bonding performance between the waterproof roll and a bottom plate, and the reliability of a waterproof layer is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of building engineering waterproofing, and in particular relates to a construction method for pre-laying anti-adhesive composite polymer waterproofing coiled materials on pile raft foundations. Background technique [0002] The water seepage problem of the basement floor has been a headache for construction companies over the years, and the traditional waterproof construction method of the basement floor is often to paste or lay the waterproof membrane on the base, which will lead to the formation of gaps between the waterproof layer and the floor Causes the separation of the waterproof layer and the structure; once the waterproof layer is damaged, the groundwater will flow around between the waterproof layer and the bottom plate, and under the action of groundwater pressure, it will penetrate from the weak point of the bottom concrete to the surface of the bottom plate, and it is not easy to find leakage At...
