Embodiment 1

[0034] Such as figure 1 and figure 2 As shown, a compound enclosure pile for building a basement includes a composite pile 1 and an enclosure pile 2. The composite pile 1 is arranged along the circumference of the basement 100 and is connected to each other to form a closed ring structure. The enclosure piles 2 surround the basement 100 and are fixedly connected with the composite pile 1. figure 1 The basement 100 shown in is a partial structure, and in actual application, the basement 100 occupies the entire area surrounded by the retaining piles 2 .

[0035] The enclosure pile 2 includes several T-shaped piles 3 with a T-shaped cross section and interconnected ones. The T-shaped piles 3 are inserted into the composite pile 1 to form a fixed connection with the composite pile 1. The composite pile 1 is cement Soil mixing piles or bored piles. The cement-soil mixing pile is a method for reinforcing the low foundation of saturated soft clay. It uses cement as the curing age...

Embodiment 2

[0045] The structure and working principle of this embodiment are basically the same as that of Embodiment 1, the difference is that the concave-convex connection mechanism 6 includes connecting blocks 63 respectively arranged on both sides of the transverse plate 31, and the two connecting blocks 63 are along the axis of the transverse plate 31 The line is symmetrical about the center. The connection block 63 has a recessed hole 64 and a protrusion 65, and the protrusion 65 is matched with the recessed hole 64, and the protrusion 65 on one connection block 63 can be inserted into the recess 64 on the other connection block 63 Thus, two adjacent T-shaped piles 3 can be clamped and fitted. Figure 8 The connecting block 53 in the middle is a hook type, which is convenient and firm to connect.

Abstract

A composite retaining pile for use in constructing a basement, comprising composite piles (1) and retaining piles (2). The composite piles (1) are arranged in the circumferential direction of a basement (100) and connected with each other to form one closed ring structure. The retaining piles (2) surround the basement (100) and are fixedly connected with the composite piles (1).

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a composite enclosure pile used for building a basement. Background technique [0002] The cement-soil mixing pile is a method for reinforcing the low foundation of saturated soft clay. It uses cement as the curing agent, and through a special mixing machine, the soft soil and the curing agent are forced to mix deep in the foundation. A series of physical and chemical reactions between them make the soft soil harden into a high-quality foundation with integrity, water stability and certain strength. Bored piles refer to the piles made by forming pile holes in the foundation soil by means of mechanical drilling, steel pipe extrusion or manual excavation on the project site, and placing steel cages in them and pouring concrete. [0003] Due to the low cost and fast production speed of cement-soil mixing piles or bored piles, they are widely used in the foundation of...
