Embodiment Construction
[0019] The features of the present invention and other related features will be further described in detail below in conjunction with the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the art:
[0020] Such as Figure 1-3 As shown, the marks 1-16 in the figure are: steel pipe section 1, socket end 2, socket end 3, socket end flange 4, socket end flange 5, opening 6, connection hole 7, cylinder base 8. Hydraulic cylinder 9, wooden gasket 10, wooden gasket 11, wedge-shaped rubber sealing ring 12, rib plate 13, steel pipe section 14, main position oil cylinder 15, auxiliary position oil cylinder 16.
[0021] see figure 1 , the construction method involved in this embodiment is mainly realized through a steel pipe section structure.
[0022] The steel pipe section structure is composed of a steel pipe section 1 and a steel pipe section 14 connected end to end. One end of the steel pipe sections 1 and 14 is a socket end 2 and...

The invention relates to the technical field of pipe jacking pushing in the underground construction, in particular to a construction method for curve steel pipe jacking, which is characterized in that a plurality of hydraulic oil cylinders are annularly arranged in a steel pipe joint, in addition, a flange is installed to be used as a stress surface between the pipe joints and between the hydraulic oil cylinders and the pipe joints, and the steel pipe jacking curve jacking and pushing is realized through the nonuniform jacking and extending of the oil cylinders. The construction method has the advantages that the curve jacking and pushing can be realized during the steel pipe jacking construction, the steering angle is convenient to change, the construction of the pipe joint structure issimple, the arrangement is compact, the cost is very low, and the construction is convenient.
Description
technical field [0001] The invention relates to the technical field of pipe jacking in underground construction, in particular to a construction method for curved steel pipe jacking. Background technique [0002] Pipe jacking construction technology is a non-excavation technology for laying underground pipelines that better protects the environment. Under the condition of not disturbing or slightly disturbing the soil structure outside the pipe, with the help of the thrust of the jacking equipment such as the main jacking pump, the tool pipe or roadheader is passed from the working well through the soil layer along the line and enters the receiving well; at the same time, A construction method for laying underground pipelines in which the following pipelines are sequentially connected and buried in the pipeline soil layer connecting the two wells. The pipes suitable for pipe jacking generally include concrete pipes (including ordinary concrete pipes, reinforced concrete pip...
