Improved column pulling equipment for hydraulic engineering

Abstract

The invention relates to improved column pulling equipment for hydraulic engineering. The improved column pulling equipment comprises a fixed supporting frame and a column body, the fixed supporting frame is movably arranged on a foundation, the column body is fixedly inserted into the foundation, a fixed clamping mechanism is arranged outside the column body in a clamping and sleeving mode, and the fixed clamping mechanism is arranged in a fixed supporting frame. The equipment can be suitable for clamping and pulling of column piles made of different materials, the problem that in the columnpile pulling process, clamping jaws and the column piles slide mutually is avoided, therefore construction efficiency is improved, meanwhile, the equipment is reasonable in structural design, in the column pile pulling process, the column piles are subjected to vertical upward pulling force, furthermore, the column piles can rotate, so that the pulling effect is improved, in the design process, amud scraping mechanism is further arranged outside the column piles, mud on the column piles can be synchronously scraped away through mud scraping equipment along with pulling of the column piles, the subsequent cleaning procedure is omitted, and the effect of efficient work is achieved.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to an improved column pulling device for hydraulic engineering. Background technique [0002] Projects built to eliminate water hazards and develop and utilize water resources. According to its service objects, it is divided into flood control engineering, farmland water conservancy engineering, hydroelectric power generation engineering, waterway and port engineering, water supply and drainage engineering, environmental water conservancy engineering, sea flat reclamation engineering, etc. A water conservancy project that can serve various goals such as flood control, water supply, irrigation, and power generation at the same time is called a comprehensive utilization water conservancy project. Water conservancy projects require the construction of different types of hydraulic structures such as dams, embankments, spillways, sluice gates, water inlets, channels, ferri...

AI Technical Summary

Problems solved by technology

②Water conservancy projects are generally large in scale, require large investment, complex technology and long construction period

[0004] However, due to the different materials of the column piles, when the same jaw is used to extract the column piles, there is a problem that the column cannot be clamped. Due to the residual muddy water on the surface of the steel column during the extraction process of the steel column, the surface of the steel column It is slippery, so when using the jaws to clamp the steel column, there is a problem that it cannot be clamped. At the same time, the existing column piles have the problem of time-consuming and laborious during the extraction process. Moreover, the existing column piles are in the After extraction, the surface needs to be manually cleaned for subsequent use. Due to manual cleaning, not only is there a problem of time-consuming and labor-intensive, but also there is a problem of low efficiency
