Force-given effect flexible stake composite presser for groundsill and its uses

Abstract

The invention relates to a flexible pile composite foundation compress machine, formed by chassis, stabilize leg, walking device, compress tube, pile support, angle control flexible drawing rod, hydraulic system formed by hydraulic device and oil tube, control system formed by motor, hydraulic electric linkage and lighting device, and weight, wherein the chassis is arranged with pile support, support pile support and angle control flexible drawing rod, which are connected via pins or bolts; another end of flexible drawing rod is connected to the pile support via pin or bolt; the compress support and relative fixing pile support form compress part; and the hydraulic system is formed by compress tube jack, oil pump and oil tube; the hydraulic output of hydraulic system is fixed on the pile support and connected to the compress tube, to extend and contract the compress tube, to form hole in soil and compress pile.

Description

technical field [0001] The invention belongs to the category of construction machines for strengthening and treating weak ground. This pile driver is especially suitable for statically pressing flexible piles of loose granular materials on weak or poor foundations such as saturated soft clay, loose powdery sand, plain fill, miscellaneous fill, and collapsible loess to form a pre-stressed composite foundation to change the soil. body load-carrying properties. Background technique [0002] There are hundreds or even thousands of ground treatment methods at home and abroad. For the reinforcement of the above-mentioned weak and bad foundations, the traditional treatment method is a single treatment method. According to its reinforcement treatment mechanism, it generally includes replacement and filling method (also known as replacement method), densification method, drainage method, reinforcement method and underpinning method (only used for the found...

Problems solved by technology

[0003] Although the specific construction methods of the above various methods can be selected according to different soil conditions, the treatment efficiency is often low, which shows that the technical and economic benefits are not high; the important thing is that these single construction methods are difficult to meet the requirements of fast and efficient reinforcement treatment, or because Due to the vibration or noise of construction machinery, etc., it has too much impact on the adjacent facilities on the ground and underground of the building and is subject to more restrictions.
