Embodiment Construction

[0028] The present invention will be further described below in conjunction with the drawings.

[0029] Reference Figure 1 ~ Figure 4 , An umbrella-shaped stepped multi-point displacement gauge anchor head for soft soil composite formations, comprising a main anchoring head 1, an upper connecting sleeve 2, a lower connecting sleeve 3, an umbrella anchoring system 4, a special-shaped multi-layer combined type Spring system 5, main indium wire 6, auxiliary indium wire 7, protective gate 8, drill hole 9.

[0030] The bottom of the main anchoring head 1 is designed as an inverted convex surface contact type. In the drill hole 9, the upper end of the main anchoring head 1 is connected to the upper connecting sleeve 2 through the first fastening lock 16A and the first fastening lock 16B, and the lower end is connected to the upper connecting sleeve 2 through the second fastening lock 17A and the second fastening lock 17A. The fixed locking card 17B is connected with the lower connecti...

Abstract

The invention relates to an umbrella-shaped step type multipoint displacement meter anchor head for soft soil compound stratums. The anchor head comprises a main anchoring head, an upper connecting sleeve, a lower connecting sleeve, an umbrella-shaped anchoring system, a special-shaped multilayer combined spring system, a main indium steel wire and a drill hole, wherein in the drill hole, the upper end of the main anchoring head is connected with the upper connecting sleeve through a first fastening lock clamp, the lower end of the main anchoring head is connected with the lower connecting sleeve through a second fastening lock clamp, and the main indium steel wire is connected with the umbrella-shaped anchoring system through the special-shaped multilayer combined spring system. According to the multipoint displacement meter anchor head, movable anchoring arm step telescopic anchor claws are respectively and synchronously driven by the special-shaped multilayer combined spring system, and the instantaneously released elastic energy is utilized, so that the movable anchoring arm step telescopic anchor claws are drilled into the soil body stage by stage for completing the anchoring. The umbrella-shaped step type multipoint displacement meter anchor head has the advantages that the anchoring effect is good, the anti-slip capability is high, the soil layer adaptability is wide, the cost is low, the measurement result is stable and reliable, and the like.

Description

Technical field [0001] The invention relates to a multi-point displacement meter anchor head, and more particularly to an umbrella-shaped stepped multi-point displacement meter anchor head for soft soil composite ground. Background technique [0002] In recent years, with the rapid economic development, many megacities have appeared in coastal soft land areas in my country, such as Shanghai, Guangzhou, Shenzhen, Tianjin, etc. During the development process of these cities, they will focus on the redevelopment of cities and will vigorously promote them. The construction of transportation infrastructure projects and new urbanization projects will usher in the "golden season" of engineering construction in my country's megacities. However, these megacities in coastal soft soil areas face many engineering problems that are different from those of inland megacities, such as large soil water content, high compressibility, and low bearing capacity. During the construction of the project...
