Problems solved by technology

Due to the construction method and construction machinery of hammering the filling material in the pile hole with a heavy hammer, it produces a lot of noise and vibration force, destroys the soil structure around the pile body, and affects the safety of adjacent buildings and the surrounding ecological environment. In addition, the expanded head of the pile end formed by the filling material is not dense, especially when the casing is lifted up directly after the pile is completed, it is easy to cause pile breakage or neck shrinkage, which will affect the construction; and there is no display of pile pressure at the pile position, which also makes each pile Different bearing capacities directly affect the pile quality
Limited by its structure, the construction of the pile driver is unstable, and counterweight is usually added, which also causes inconvenience to use.

Embodiment 1

[0025] i. Install the static pile driver: After the static pile driver of the static pressure sinking pipe bottom expansion concrete pile is put in place at the set position, first anchor the anchor rod of the anchor mechanism into the soil layer to open the anchor thorn, and put the static pressure The pile driver is positioned and fixed; ii. Lower casing: Operate the hydraulic clamping swing lifting mechanism of the static pile driver to press the casing into the ground to the design elevation, and the static hydraulic hammer in the casing follows up to the design elevation synchronously ; iii, stuffing: operate the winch of the static pile driver to lift the static hydraulic hammer, fill the filler into the casing; lift the static hydraulic hammer, fill the filler into the casing; iv, press the bottom of the pile to expand Body: insert the static hydraulic hammer into the casing, make the hydraulic cylinder connection seat of the static hydraulic hammer lock and connect with...

Embodiment 2

[0027] According to embodiment 1, in v, pile making process, be to adopt after laying reinforcement cage in the pile hole, pour concrete into pile; Other operations are identical with embodiment 1.

[0028] See attached figure 2 , image 3 , the composition of the static pile driver of the present invention is provided with a body, a main rod 1, a winch, a casing 10, a hydraulic cylinder 2, a static hydraulic hammer 7, a hydraulically tightened swing lifting mechanism, an anchoring mechanism and an intelligent digital display. An intelligent digital display is installed on the console of the static pile driver body. The main rod connected to the body frame of the static pile driver is the main rod 1 with a slide frame at the bottom. The inner sides are equipped with a hydraulically tightened swing lifting mechanism connected to the casing, and the outer two slides are equipped with anchoring mechanisms. The mouth is connected to the hydraulic cylinder 2, and the hydraulic cy...

Abstract

A static pressure sinking pipe bottom-expanded concrete pile construction method and a static force pile driver thereof are disclosed, the method is used for solving the problems in the current construction, the technical proposal comprising the steps of: installing the static force pile driver; sinking a guard sleeve; filling the filling materials into the guard sleeve; casting a pile bottom-expanded body; placing a pre-cast concrete pile into the pile hole; lifting the guard sleeve; completing the construction. The invention also provides a structure of the used static force pile driver. The invention efficiently settles the issues in the construction method for the current concrete pile and the construction thereof, like large vibration force and mechanical noise, incompact pile end expansion head formed by the filling materials, and the invention is stable in quality of pile and convenient in usage, which is applicable for the constructions of construction piles such as the staticpressure sinking pipe bottom-expanded carrier pile, perfusion pile and pre-cast pile.

Description

technical field [0001] The invention relates to a concrete pile construction method and a construction machine in building foundation engineering technology. Background technique [0002] With the increasing development of the construction industry, the technical requirements for construction foundation engineering, especially foundation pile foundation, are also constantly improving. In the known technology, the existing concrete pile construction method usually adopts heavy hammer hammering, and the steel wire rope connected by the hoist is used to pull down the casing through the pulley, and the pile hole is filled with bricks and stones with the heavy hammer hammering to make it in the pile hole. The expansion head is formed at the bottom, and then the reinforcement cage is placed, the concrete is poured, and the casing is lifted out to complete the construction of the concrete pile. Due to the construction method and construction machinery of hammering the filling mate...
