Radical anchorage and construction method thereof

Abstract

A root type guy anchor and a construction method thereof are in characterized in that a tabular bearing table is provided, the bottom of the tabular bearing table is provided with a T-shaped bearing anchor pipe, the lateral wall of the anchor pipe is provided with a root key raised out of the external wall of the anchor pipe and installed along the radial direction of the anchor pipe, and the bottom of the anchor pipe is a back cover formed by concrete. The invention greatly optimizes the base and guy anchor and greatly strengthens the friction force by adopting the root type structure. The gripping force of soil body to the root key improves the structure stability providing possibility of reducing structure gravity, thereby having better economical efficiency, simple technique, quick construction, as well as reliability and safety.

Description

Root anchorage and its construction method This application is a divisional application of the invention patent application with the application number: 200610038147.5, the application date: January 26, 2006, and the invention name: root foundation, anchorage and construction method. technical field The invention relates to an anchor in civil engineering, bridge building and hydraulic structure, and a construction method for the anchor. Background technique Traditional anchorages mainly include large-scale caissons, underground diaphragm walls, freezing method construction foundations, row pile support construction method foundations and other structural forms. A large caisson relies on its own gravity and the reaction force of the surrounding soil to balance the pulling force of the cable. The disadvantages are that the foundation size is large, the sinking is deep, there are many separations, the construction is difficult, and the caisson is easy to shift during const...

AI Technical Summary

Problems solved by technology

The disadvantage of this scheme is that the requirements for geological conditions are relatively high, the phenomenon of backsliding hole collapse and the verticality of piles must be strictly controlled during drilling construction, and there is a risk of water leakage during foundation pit open excavation construction
