Rapid green construction removal device for urban waste foundation

Abstract

The invention discloses a rapid green construction cleaning device for urban waste foundations. The rapid green construction cleaning device comprises hoisting equipment, a vibrating hammer, a positioning steel plate, an installation frame, a sleeve assembly, at least two traction devices, a first steel wire rope and at least two second steel wire ropes, wherein the sleeve assembly comprises an inner barrel body and an outer barrel body, the inner barrel body is arranged in the outer barrel body in a sleeved manner, the upper end of the outer barrel body is detachably fixed to the vibrating hammer, a twist drill is arranged inside the sleeve assembly, and each traction device comprises a rack which is vertically arranged on the outer barrel body, a gear which is installed on a supporting leg and meshed with the rack, a guide pulley which is installed on the supporting leg and is in belt transmission with the gear and a winch which is fixed to the positioning steel plate and is in belt transmission with the guide pulley. According to the rapid green construction cleaning device for the urban waste foundations, old piles are drilled through the twist drill, the sleeve assembly supports the old piles, a soil compaction effect is formed, the gears and the racks are meshed to assist in lifting steel wire ropes, pile heads are firm in clasp and good in guiding performance, disturbance to surrounding underground soil and adjacent structures does not exist, and the rapid green construction cleaning device for the urban waste foundations has the advantages of being flexible and convenient to construct, high in pile pulling efficiency, green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of urban construction. More specifically, the invention relates to a rapid green construction removal device for urban waste and old foundations. Background technique [0002] With the rapid advancement of China's urbanization process, the old pile foundations of original buildings affect the foundation and foundation pit construction of various new construction, reconstruction and expansion projects, which has attracted the attention of owners, design and construction circles. For the removal of prefabricated piles, sinking piles, and cast-in-situ piles, the existing technology often smashes the old piles by impact drilling, and then digs them out bit by bit. The process is complicated and takes a long time, and it is not energy-saving and environmentally friendly. The water-jet method injects a large amount of water around the old pile, and the water jet follows the casing wall. The construction process h...

Problems solved by technology

For the removal of prefabricated piles, sinking piles, and cast-in-place piles, the existing technology often smashes the old piles by impact drilling, and then digs them out bit by bit. The process is complicated and takes a long time, and it is not energy-saving and environmentally friendly.

A large amount of water is injected around the old piles for pile extraction by water jetting, and the water jets follow up the casing wall. During the construction process, the soil is greatly disturbed, the work efficiency is low, and the risk of subsequent construction is increased.

However, the vibration method is used directly to pull out piles. The vibration will cause the old piles to resonate with the soil, and the locks will be tightened to pull out the piles. There are problems such as insufficient pile pulling force, heavy equipment, low pile pulling efficiency, and not being environmentally friendly.
