Embodiment Construction

[0011] The composite pile shown in Figure 1 includes a pile core 1 and an outer layer pile 2 wrapped outside the pile core 1, the outer layer pile 2 is a cement-soil pile, and the pile core 1 is a prestressed pile with a circular cross section. Concrete piles.

[0012] Above-mentioned composite pile can adopt following method to make:

[0013] The method comprises the following steps: a. adopting a high-pressure jet mixing method to manufacture cement-soil piles; b. hoisting the prestressed concrete pipe piles, aligning them with the center of the cement-soil piles and vertically inserting, driving or pressing them to the design pile top elevation to form piles. When the length of a single pipe pile is not enough, piles can be connected.

[0014] The composite pile can be made with reference to the parameters in the table below:

Abstract

The present invention discloses one kind of composite pile comprising one pile core of high strength pre-stressed concrete pipe and one outer layer pile of soil cement coating the pile core and its construction process. The construction process includes the following steps: 1. high pressure spraying and stirring to form the outer layer pile; and 2. hoisting the pre-stressed concrete pipe pile and inserting or pressurizing into the center of the outer layer pile until reaching the designed depth. The composite pile has the advantages of both soil cement pile and reinforced concrete pile, vertical load borne by the pre-stressed concrete pipe pile and the side friction force transferred by the soil cement pile with relatively great cross section. It has clear stress mechanism, great bearing capacity and reliable quality.

Description

(1) Technical field [0001] The invention relates to a composite pile, in particular to a composite pile whose outer layer is a cement-soil pile. The invention also provides a construction method of the composite pile. (2) Background technology [0002] The outer layer disclosed and used in the market is a composite pile of cement-soil pile, which consists of a reinforced concrete pile core with a small cross-section inserted into a larger cement-soil pile as a force-bearing body. The diameter of the cement-soil pile formed by the traditional deep mixing method or the single-pipe high-pressure injection method is relatively small, generally 500mm to 600mm. The pile core generally adopts a reinforced concrete prefabricated square pile with a side length of 200mm. This kind of reinforced concrete prefabricated square pile needs to be fabricated on site, and the construction period is long. Due to the small cross-section of pile core and cement-soil pile, its single pile bearin...
