Problems solved by technology

First of all, the mechanical connection method requires that the upper and lower pile bodies correspond to each other so that the embedded parts can be connected accordingly. Therefore, it is often necessary to adjust the position of the pile body during construction, which takes a lot of time; secondly, the mechanical connection structure is easy to loose during pile sinking. Thus affecting the overall tensile and compressive physical properties of the pile

Embodiment Construction

[0026] combined with figure 1 to attach Figure 8 Describe the structure and principle of the present invention.

[0027] Such as figure 1 As shown, when the structure is used to connect prefabricated piles, a reinforced connection structure is provided between the upper section 1 of the prefabricated piles and the lower section 2 of the prefabricated piles to improve the physical properties of the prefabricated piles, especially the tensile, compressive and shear properties. Reduce breakage and damage during construction due to silt layers, isolated stones or foundation excavations. It can be seen from this figure that the ends of adjacent prefabricated piles are provided with pile end plates 5 and pile collars 4 . The pile collar and the pile end plate are welded and fixed, specifically as figure 2 As shown, the pile collar and the pile end plate are welded by submerged arc welding. The connecting plate 3 for reinforcement is welded on the pile hoop 4 along the circumf...

Abstract

The invention discloses a precast pile reinforcement structure and a durable pile foundation. The precast pile reinforcement structure comprises pile end plates, pile hoops and a plurality of connecting plates. The pile end plates are arranged at the ends of precast piles. The pile hoops are fixedly connected with the corresponding pile end plates. The connecting plates are welded to the pile hoops at the ends of the adjacent precast piles. By adopting the precast pile reinforcement structure, the technical problems existing in the prior art can be solved; the tensile strength and compressive strength of the precast piles are greatly improved through reinforcing plates, and damage in the construction process is reduced. Meanwhile, the precast pile reinforcement structure is more convenient and faster than mechanical connection modes.

Description

technical field [0001] The invention relates to pile foundation technology, especially prefabricated pile technology. Background technique [0002] In some thick silt areas, such as coastal areas or lakeside areas, prefabricated piles (including pipe piles, square piles, or polygonal piles, etc., the same below) are easy to be damaged during excavation or under horizontal force, increasing The construction cost affects the construction progress. [0003] In order to solve the above problems, technicians have proposed a new design, that is, adopting a mechanical connection structure. For example, in patent 201210411014.3, a quick-connect joint is provided at the end of the pipe pile. The joint includes a flange plate and a hoop plate. The hoop plate is provided with a fitting groove, and the flange plate is correspondingly provided with a flange. The two are fitted together. form a connection structure. There are many similar mechanical connection methods, but in actual co...
