Embodiment 1

[0033] Such as figure 1 As shown, a compound enclosure pile structure includes a T-shaped pile 1 with a T-shaped cross section, and a composite pile 2 whose axis line is parallel to the T-shaped pile 1. The T-shaped pile 1 is provided with A number of anchor rods 3, and one end of the anchor rod 3 is fixedly connected to the T-shaped pile 1, and the other end is inserted into the composite pile 2 to form a fixed connection with the composite pile 2, such as figure 2 As shown, the T-shaped pile 1 includes a transverse plate 11 and a longitudinal plate 12 connected to each other. Such as image 3 As shown, there are several anchor rods 3 located on both sides of the longitudinal plate 12 , preferably, the anchor rods 3 located on both sides of the longitudinal plate 12 are evenly distributed. In order to strengthen the fixing effect of the anchor rod 3 , a connecting rod 31 parallel to the axis of the transverse plate 11 is fixed inside the transverse plate 11 , and the conne...

Embodiment 2

[0040] The structure and working principle of this embodiment are basically the same as that of Embodiment 1, the difference is that, as Figure 7 and Figure 11As shown, the concave-convex connection mechanism 5 includes connecting blocks 53 respectively arranged on both sides of the transverse plate 11 , and the two connecting blocks 53 are centrally symmetrical along the axis of the transverse plate 11 . The connection block 53 has a concave hole 54 and a protrusion 55, and the protrusion 55 is matched with the concave hole 54, and the protrusion 55 on one connection block 53 can be inserted into the concave hole 54 on the other connection block 53 Therefore, two adjacent T-shaped piles 1 can be clamped and fitted. Figure 7 The connecting block 53 in the middle is a hook type, which is convenient and firm to connect.

Abstract

A composite retaining pile structure comprising a T-shaped pile (1) having a T-shaped cross-section, also comprising a composite pile (2) having the axis line thereof parallel to the T-shaped pile (1). Several anchor rods (3) are arranged on the T-shaped pile (1). The anchor rods (3) are fixedly connected at one extremity thereof to the T-shaped pile (1) and inserted at the other extremity into the composite pile (2) and form fixed connections with the composite pile (2).

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a compound enclosure pile structure. 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] The above-mentioned two kinds of piles have the advantages of low cost and high manufacturing speed, but their stability and strength are not as good a...
