Anti-slip cement soil pile soil blocking structure and construction method thereof

Abstract

The invention relates to the technology of reinforcing, supporting and protecting soft rock soil in the rock engineering. An anti-slip cement soil pile soil blocking structure is formed through the addition of a cement soil anti-slip pile body in the soft soil body and the combination. The anti-slip cement soil pile soil blocking structure overcomes various defects of the common soil blocking structure, and belongs to a novel structure with the advantages of safety, environment protection, economy and fast construction. The anti-slip cement soil pile soil blocking structure and a construction method thereof are characterized in that vertical cement soil piles, vertical hole drilling filled piles, steel plate piles, underground continuous walls and the like as well as cement soil anti-slip piles (with different lengths and inclination angle) tension, pull and lock the added rib bodies arranged in an anti-slip pile body through horizontal walings for being combined into the soil blocking structure, wherein tensioning bodies (such as steel stranded wires, steel pipes, cable wires, formed steel, non-metal materials and the like) are inserted inside the vertical cement soil piles, the vertical hole drilling filled piles, the steel plate piles, the underground continuous walls and the like. Through the pre-reinforcing on the soft soil body and the pre-tensioning pulling on the added rib bodies in the anti-slip pile by the soil block structure, the stability of the reinforced, supported and protected soil body is greatly improved, and the horizontal and vertical displacement amount is greatly reduced.

Description

1. Technical field [0001] The invention relates to the reinforcement and support technology for weak rock and soil in geotechnical engineering. By adding cement-soil anti-slide piles into the weak soil and combining them to form a retaining wall, the reinforcement and support will be greatly improved. capacity and reduce project cost. 2. Technical Background [0002] In the engineering construction in my country's coastal and riverside areas, there are generally characteristics of weak foundation soil, poor stability, and low bearing capacity. Especially in economically developed areas, the cost used for foundation treatment and foundation pit enclosure is There will be more than 100 billion yuan. At present, in the foundation treatment and foundation pit enclosure engineering in my country, the retaining structures mainly include underground diaphragm wall, bored pile, soil nail wall, SMW construction method and pile-anchor structure. There are often many construction techn...

AI Technical Summary

Problems solved by technology

In order to achieve the purpose of retaining soil, it is necessary to combine H-shaped steel in the deep mixing pile with internal support or anchor rod together with the underground diaphragm wall and bored pile to form a retaining structure, which often causes great difficulties in design and construction and makes construction The cost has increased significantly

[0003] In view of the shortcomings of the above-mentioned retaining structures, such as construction difficulty and high cost, after years of experimental research, we have invented a new retaining structure - anti-sliding cement-soil pile retaining wall, which not only overcomes the It overcomes the shortcomings of the commonly used retaining structures, and is a new type of structure that is safe, environmentally friendly, economical, and fast in construction.
