Novel construction concrete pipe pile based on anti-penetration technology and its preparation method

Abstract

The invention discloses a new type of construction concrete pipe pile based on anti-penetration technology, belonging to the field of concrete pipe piles. The new type of construction concrete pipe pile based on the anti-penetration technology comprises a hollow steel reinforced pipe column. A laterally expanding body, which is clad and poured layer by layer through the hollow steel pipe column, the concrete body and the anti-seepage body, is beneficial to improve the overall mechanical strength of the concrete pipe pile. The anti-seepage body can play a good role in preventing seepage and waterproofing. The pipe pile is not easily damaged by groundwater and rainwater infiltration, and a plurality of lateral expansion bodies that expand outward under the action of pressure are set on the outside of the hollow steel pipe column. After the seepage body is poured, the concrete body is poured into the anti-seepage body through the pouring hole. Under the action of high-strength pouring pressure, a plurality of elastic steel bars are forced to expand to the outside of the anti-seepage body, which is beneficial to improve the mechanical connection with the pouring earthwork layer laterally. strength.

Description

technical field [0001] The invention relates to the field of concrete pipe piles, more specifically, relates to a new construction concrete pipe pile based on anti-penetration technology. Background technique [0002] In the modern construction industry, foundations and piles are one of the most important parts of construction. Concrete pipe piles are piles made of concrete (including ordinary reinforced concrete and prestressed concrete), which have the advantages of saving wood and steel, durable and low cost. , has been widely used in the foundation engineering of hydraulic construction, industrial construction, civil construction and bridges, and is also commonly used in anti-skid or water isolation of slope and foundation pit support. When the foundation of the building is laid and the concrete pile is built, the pile hole is usually drilled first, and then the prefabricated steel cage or steel pipe is put into the pile hole, and the concrete is poured, and the concrete...

AI Technical Summary

Problems solved by technology

[0003] The existing ordinary concrete pipe piles have poor anti-seepage performance. After a certain period of use, gaps will be formed on the end walls due to external natural factors, and groundwater and rainwater will often penetrate into the interior of the concrete pipe piles along the gaps. Concrete pipe piles are seriously affected by immersion in their mechanical strength, so that they cannot achieve a good load-bearing effect. In addition, the lateral connection between the pipe piles and the poured soil is not stable enough, so after long-term use, it will affect the strength of the poured earthwork. Reduced bearing strength
