Hydraulic hammering type concrete cast-in-place pile equipment

Abstract

The invention relates to hydraulic hammering type concrete cast-in-place pile equipment. The equipment comprises a flying ring, a steel pipe, and a steel pipe and a grouting steel pipe, which are arranged at the upper end; the grouting steel pipe is arranged in the steel pipe, wherein the lower end of the steel pipe is connected with the upper end of a hydraulic hammer housing; a hammer body is arranged in the housing; a drive hydraulic cylinder is arranged below the hammer body; a cone is arranged at the lower end of the hydraulic hammer; the grouting steel pipe is also arranged in the middle of the hydraulic hammer; and a grout holdback system is arranged at the lower end of the grouting steel pipe. The hydraulic hammer is arranged in the soil in operation, so that no noise pollution is generated; and arranged at the lower end of a piling pipe, the hydraulic hammer has a low center of gravity, so that a special pile frame is not required, and the construction is carried out by a common crane, which brings convenience.

Description

1. Technical field [0001] The invention relates to concrete pouring pile equipment, in particular to hydraulic hammering concrete pouring pile equipment for building foundations. 2. Background technology: [0002] Hammered concrete cast-in-situ pile is a pile hammer that is hung by a special pile frame, and a pile pipe is set at the lower end of the pile hammer. The pile hammer drives the pile pipe into the ground, and then pours concrete in the process of pulling out the pile pipe to form concrete For cast-in-situ piles, since the pile hammer hammers or vibrates the pile pipe above the ground, it produces huge noise, and because the center of gravity is relatively high when the pile hammer hammers the pile pipe, a special pile frame is required to lift, which brings great inconvenience. 3. Contents of the invention: [0003] The present invention overcomes the above disadvantages and provides a hydraulic hammering type concrete pouring pile equipment. [0004] The presen...
