A construction technique of hoisting and hoisting in pipe jacking construction in confined space

Abstract

The invention discloses a lifting and hoisting construction technology in a pipe jacking construction process under a limited space. The lifting and hoisting construction technology comprises the following steps that 01), a cantilever crane is selected for replacing conventional equipment to carry out pipeline hoisting; 02), slag discharging in a pipe jacking machine is carried out by adopting anelectric vehicle and a slag bucket to cooperate with manual work for performance, a main cantilever crane is arranged at the position close to a working well wall, and meanwhile, one cantilever craneis arranged in a working well to cooperate with a soil discharging slag bucket for circulation; 03), the cantilever crane is arranged on a perpendicular line of the direction of a pipeline closest toa pipeline installation point, a foundation of the cantilever crane is made of reinforced concrete, and the foundation is arranged close to the side edge of the working well; and 04), hoisting is carried out, wherein pipes are stably stacked and placed in the hoisting range of the cantilever crane, moreover, wooden cushion blocks are used for firm cushioning, the cantilever crane firstly hoists the pipes by 20-50 cm, and after hoisting is stable, lifting and rotating can be carried out. According to the provided lifting and hoisting construction technology in the pipe jacking construction process under the limited space, hoisting can be achieved without ground buildings modified and moved, the working efficiency is improved, and the overall progress of the pipe jacking construction is accelerated.

Description

technical field [0001] The invention relates to the field of pipe jacking construction and hoisting, in particular to a construction technology for hoisting and hoisting in pipe jacking construction in a confined space. Background technique [0002] With the continuous improvement of urban construction, the use of pipe jacking construction in urban construction is becoming more and more extensive. The lifting and hoisting operations in pipe jacking construction are frequent, but limited by the ground buildings, the lifting and hoisting operations are sometimes Extremely inconvenient. In the pipe jacking construction and hoisting operation of existing projects, the ground buildings are usually relocated to meet the operating conditions of conventional hoisting machinery such as truck cranes, but the relocation of the ground buildings not only increases the construction period and construction costs, but also increases the impact on the ground The original buildings will have...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages of increasing the construction cost and affecting the original buildings on the ground caused by the relocation of the ground buildings in the existing pipe jacking construction and hoisting operations, and provide a method that can meet the requirements of hoisting without changing the ground buildings. Lifting and hoisting construction technology in pipe jacking construction in confined space, which improves work efficiency and speeds up the overall progress of pipe jacking construction
