A cement-soil retaining wall pouring row pile and its construction method

Abstract

The invention discloses a cemented soil retaining dado cast-in-place row pile and a construction method thereof. The casting row pile comprises a plurality of mixing piles which are distributed along an extension direction of a cemented soil retaining dado cast-in-place pile supporting structure, wherein part of any one mixing pile is embedded into another adjacent mixing pile; and cast-in-place piles are respectively arranged in the mixing piles. In the hole digging and grouting process of the cast-in-place pile structure construction, the grouting materials of the mixing piles can be saved; moreover, all the cylindrical piles are intersected with one another after reinforcement cages are descended to complete the casting, the water-resistant capability of the integral row of cast-in-place piles can be improved; and the cast-in-place row pile can be used in the construction field.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a cement-soil retaining wall pouring pile row and a construction method thereof. Background technique [0002] With the development of engineering construction, many breakthroughs have been made in pile foundation construction technology, and new pile types, construction techniques and matching machines and tools are constantly emerging. As we all know, the commonly used bored and punched cast-in-situ piles adopt the mud wall protection method. During the hole forming process, stress relaxation will occur, and the wall protection mud formed after the hole is formed will weaken the frictional resistance of the pile side, and the sediment at the pile end will Weaken the bearing capacity of the pile ends, a large amount of mud generated during hole forming will pollute the environment and cause secondary pollution, and it is difficult to achieve tangency between the piles, and t...

As we all know, the commonly used bored and punched cast-in-situ piles adopt the mud wall protection method. During the hole forming process, stress relaxation will occur, and the wall protection mud formed after the hole is formed will weaken the frictional resistance of the pile side, and the sediment at the pile end will Weaken the bearing capacity of the pile ends, a large amount of mud generated during hole forming will pollute the environment and cause secondary pollution, and it is difficult to achieve tangency between the piles, and there is a certain gap between the piles, so another water-stop curtain needs to be made, which increases the project cost. input cost
