Hydraulic engineering cast-in-place pile based on air-lift reverse circulation hole cleaning

Abstract

The invention provides a hydraulic engineering cast-in-place pile based on air-lift reverse circulation hole cleaning. The cast-in-place pile comprises a working table, supporting tables, a steel protection tube, a guide pipe, a pile hole inner wall, a sand outlet dust fall cover structure, a guide wheel protection sleeve structure, a measuring ruler reel structure, a spiral sand blowing pipe structure, a slag receiving basket, moving wheels, a fixing table, supporting legs, an air compressor, air pipe, a rheid measuring ruler, a diving switch and a wind power switch, wherein the supporting tables are connected to the left and right sides of the lower end of the working table through bolts respectively. The cooperative arrangement of a dust fall plate, a sand inlet pipe, a rubber ring andthe guide pipe is beneficial to preventing the surrounding working environment from being polluted in sand blowing; the arrangement of an air distribution pipe, a connecting plate, a rotating motor and a conical head is beneficial to reducing the blocking of sand and preventing sand from blocking the air pipe when the air pipe is conveyed downwards; the arrangement of the rheid measuring ruler, aconnecting rod, a winding wheel and a connecting block is beneficial to measuring the depth of a pile hole and preventing the work from being affected by a too small or too large pile hole depth.

Description

technical field [0001] The invention belongs to the technical field of cast-in-place piles, and in particular relates to a water conservancy engineering cast-in-place pile based on gas lift reverse circulation cleaning. Background technique [0002] The hole is directly opened on the designed pile position, and its cross section is circular. After the hole is formed, a steel cage is added in the hole, and concrete is poured into it. Due to the advantages of being used in dense urban areas, cast-in-place piles have been widely used in construction. According to the different hole-forming techniques, cast-in-place piles can be divided into dry-worked cast-in-place piles, mud walled cast-in-place piles and artificial excavation. Cast-in-place piles with holes, etc. According to their different hole-forming methods, cast-in-place piles can be divided into bored cast-in-place piles, immersed pipe cast-in-place piles, artificially dug bored cast-in-place piles, blast-expanded cast...
