Description

Technical Field

[0001] The utility model relates to a waterproof structure, in particular to a pile head sealing waterproof structure. Background Art

[0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation, is referred to as a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations. In high-rise buildings, pile foundations are widely used. The pile head is generally composed of concrete or reinforced concrete, which is the part that is in closest contact with groundwater. When carrying out construction, the bottom of the building usually uses a pile foundation as the deep foundation structure of the entire building. The pile foundation has the characteristics of high bearing capacity and a wide range of applications. It is widely used in high-rise buildings, ports, bridges and other projects. In the pile foundation, multiple piles driven into the ground are used as the main load-bearing components to carry the subsequent structure cast on the pile foundation, and the pile head refers to the upper part of the pile, usually the top of the pile. Pile heads play an important role in construction, especially in pile foundation construction. If the pile heads are not waterproofed, they will face the risk of erosion and leakage by groundwater, which will cause corrosion and deformation of the pile heads and even affect the stability of the entire civil engineering structure. For this reason, the pile heads need to be waterproofed.

[0003] At present, in the prior art, cement-based penetrating crystalline waterproof coatings and waterproof mortars are mostly used to construct the waterproofing of the pile heads. However, the waterproof mortar may be damaged during use due to the lack of a protective structure. Therefore, the present application proposes a pile head sealing waterproof structure to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a pile head sealing waterproof structure to solve the problem that in the prior art proposed in the above background technology, the waterproofing of the pile head is mostly constructed by using cement-based penetrating crystalline waterproof coating and waterproof mortar, but the waterproof mortar may be damaged during use due to the lack of a protective structure.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pile head sealing waterproof structure comprises a ground, wherein a pile foundation body is fixedly installed inside the ground, one end of the pile foundation body passes through the ground, a waterproof mortar is arranged at the connection between the ground and the pile foundation body, a waterproof coating layer is arranged on the outside of the waterproof mortar, and a protective plate is arranged between the ground and the pile foundation body and on the outside of the waterproof coating layer.

[0007] As a further solution of the utility model: first bolts are symmetrically arranged on both sides of the protective plate, and the protective plate is fixed to the ground through the first bolts.

[0008] As a further solution of the utility model: second bolts are symmetrically arranged on both sides of the protective plate and above the first bolts, and the protective plate is fixed to the pile foundation body through the second bolts.

[0009] As a further solution of the utility model: a first baffle is fixedly installed on the outer side of the protective plate and above the first bolt.

[0010] As a further solution of the utility model: a second baffle is fixedly installed on the outer side of the protective plate and above the second bolt.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides a good waterproof effect by arranging waterproof mortar at the connection between the pile head and the ground, and arranging a waterproof coating on the outside of the waterproof mortar. At the same time, in order to protect the waterproof mortar and the waterproof coating layer, a protective plate is also provided on the outside of the waterproof mortar and the waterproof coating layer. The protective plate provides protection for the waterproof mortar and the waterproof coating layer, thereby effectively improving the service life of the waterproof mortar and the waterproof coating layer.
