Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but the present embodiments do not constitute any limitation to the present invention.
[0022] see figure 1 , figure 2 , a construction technique of using the nylon wheel transporting steel pipe device in the pipe jacking project to carry out the construction process of wearing the steel pipe inside the outer protective pipe, which is carried out according to the following steps:
[0023] (1) Customize the nylon wheel 1 according to the size of the concrete outer protective pipe 4 and the inner steel pipe 5; according to the distance between the nylon wheel 1 and the inner wall of the concrete outer protective pipe 4 h=1 / 2×(the inner diameter of the concrete outer protective pipe 4 D-the outer diameter of the steel pipe 5 Diameter d), the error control is between -2mm-0mm, and the nylon wheel steel bracket 2 is made; the length of the nylon wheel ste...

The invention relates to a device for transporting steel pipes by a nylon wheel in a pipe jacking project and a construction process. Including: custom-made nylon wheels; making nylon wheel steel brackets; installing three sets of nylon wheels at intervals of 4.5 meters on the inner wall of the concrete outer protective tube, one nylon wheel is at the bottom middle of the inner wall of the concrete outer protective tube, and the other two nylon wheels are on the concrete outer protective tube. The left and right sides of the inner wall of the outer protective pipe; place one end of the steel pipe at the entrance of the concrete outer protective pipe, pull it with a hoist, and roll it through with the aid of nylon wheels; stop passing when the other end of the steel pipe is exposed at the nozzle of the concrete outer protective pipe; connect the subsequent steel pipe with the exposed Weld the end of the steel pipe, and then continue to wear the pipe until the steel pipe is completely penetrated; the anchor shotcrete machine and the air compressor form the sand blowing equipment, and blow medium and coarse sand into the gap between the concrete outer protective pipe and the steel pipe until the density is reached. Meet the requirements. The invention can ensure the central axis and elevation of the steel pipe, is convenient for construction, solves the resistance problem and reduces the cost.
Description
technical field [0001] The invention relates to a construction process of an outer protection pipe and an inner steel pipe in pipe jacking construction, in particular to a device and a construction process for conveying steel pipes by nylon wheels in a pipe jacking project. Background technique [0002] In the pipe jacking construction, the steel pipe passes through the concrete outer protection pipe. The traditional technology adopts the bamboo skin protection pipe method and the steel pulley bracket method. The bamboo skin protection pipe method has large resistance and the position of the steel pipe is difficult to control; It can reduce pipe penetration resistance, but steel pulleys are expensive and uneconomical. Contents of the invention [0003] The object of the present invention is to provide a nylon wheel instead of a steel pulley, which not only solves the problem of resistance, but also reduces the cost of the device and construction process for transporting st...
