Problems solved by technology

[0002] In the construction of traditional elevated roads or viaducts, a large number of pile holes need to be drilled. During the hole forming process, a large amount of waste residue needs to be transported, and the waste residue in the pile holes is often difficult to remove, resulting in problems with the quality of the pile foundation.

Abstract

The invention discloses a compound type pile foundation construction site structure. The compound type pile foundation construction site structure comprises a first pile hole, a slurry settling pond, a slurry standby pond and a second pile hole, wherein the first pile hole is conducted with the slurry settling pond via an oblique groove; the slurry settling pond is communicated with the slurry standby pond via a first external pipeline; the first external pipeline is provided with a pump and a filter screen; the slurry standby pond is connected with a second external pipeline; the second external pipeline is provided with a pump and an outlet facing to the second pile hole; a third external pipeline is arranged between the second pile hole and the slurry settling pond and is provided with a pump. The invention also provides a construction process implemented by application of the compound type pile foundation construction site structure. Through the scheme, the external transportation amount of waste residues formed by drilling can be reduced; the pile hole cleaning speed is accelerated; the holes are cleaned by normal circulation of impact drilling of the slurry; the wall protection effect is excellent; the sediment residues at the bottoms of the holes can be effectively controlled; and the cost can be greatly reduced.

Description

technical field [0001] The invention relates to a composite pile foundation construction site structure. The invention also relates to a construction technique implemented by using the composite pile foundation construction site structure. Background technique [0002] In the construction of traditional elevated roads or viaducts, a large number of pile holes need to be drilled. During the hole forming process, a large amount of waste residue needs to be transported, and the waste residue in the pile holes is often difficult to remove, resulting in problems with the quality of the pile foundation. Contents of the invention [0003] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a composite pile foundation construction site structure that can reduce waste residue and speed up construction. The invention also provides a construction technique implemented by using the composite pile foundation construct...
