Problems solved by technology
However, there are many ways for pipes to pass through the outer wall of the basement, and the requirements for waterproofing are not as high as those for rafts.
With the development of large-scale buildings and the development of energy-saving technology, ground source heat pump air-conditioning requires various practices, and buried pipes passing through rafts will be an economical and applicable choice, but the waterproof requirements of rafts are high, and there is a lack of reliable methods.

Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention is further described:
[0022] refer to Figure 1~2 As shown, the present invention provides a kind of waterproof method that buried pipes penetrate building foundation rafts, comprising the following steps:
[0023] (1) Lay the buried pipe 2 under the raft 1 of the building foundation to be poured, and fix the buried pipe perpendicular to the ground according to the pipe outlet position and spacing of the buried pipe 2, and then pour the raft cushion 3 of the building foundation. A high-density polystyrene board 5 is arranged at the corresponding position under the tube 4;
[0024] (2) The waterproof layer 6 is laid on the raft cushion layer 3 of the building foundation and the high-density polystyrene board 5, and the waterproof layer near the buried pipe 3 is turned up, and the upper side of the turned-up waterproof layer is set to expand when it encounters water. Waterstop 7;

The invention relates to a waterproofing method for penetration of a buried pipe set into a building foundation raft. According to the structure, a waterproof steel plate is connected with a waterproof sleeve of the buried pipe set, upstream face and downstream face waterproof layers are formed on the upper and lower portions of the waterproof steel plate, waterproofing of the basement foundationraft can be complete, and the foundation raft structure and the foundation raft overall waterproof performance are not weakened; the flexible waterproof method in the waterproof sleeve is improved, and the waterproof performance is strengthened; and antiseptic and anti-corrosion measures are taken to the flexible waterproof top end, and maintenance of the waterproof device is facilitated.
Description
technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a waterproof method for piercing building foundation rafts with buried pipes. Background technique [0002] With the promotion of buried pipe ground source heat pump renewable energy energy-saving projects, there are more and more projects under the construction foundation of buried pipes. Due to the large size of the basement, it is impossible to enter from the outside of the building, and it is not suitable to set up a small pipeline subsidence in the basement floor; buried pipes enter the basement and the indoor heat pump room through the raft, which is the most economical solution for saving materials and energy; [0003] Under normal circumstances, there are many buried pipes passing through the raft, and multiple buried pipes form a group, and enter the sub-catchment in the basement according to the group. However, there are many ways for pipes...
