Description
Technical Field
The utility model belongs to the technical field of the combined material pipeline, specifically speaking relates to a corrosion-resistant high pressure glass steel push pipe.
Background
The pipe jacking technology is a trenchless tunneling type pipeline laying construction technology used for municipal construction. The method has the advantages of no influence on the surrounding environment or less influence, small construction site and low noise. But also can be deeply operated underground, which is incomparable with the advantages of digging and burying pipes.
The trenchless engineering technology thoroughly solves the problems of damage to urban buildings, road traffic blockage and the like in pipeline embedding construction, and has obvious advantages in soil stabilization and environmental protection. This is very important for cities with heavy traffic, dense population, numerous ground buildings and complex underground pipelines, which will create a clean, comfortable and beautiful environment for the cities.
Trenchless technology, which is a term frequently used in recent years, relates to laying or replacing underground pipelines by using trenchless, i.e., working wells and receiving wells, and trenchless, i.e., pipe trenchless, technology, with a jacking pipe diameter DN 800-4500. The pipe to be buried is pushed into the ground through the working well, and the pipe in the working well can pass through the ground for more than 2000 meters and can also pass through a curve to bypass some underground pipelines or barriers.
The technical point of the method is to correct the deviation of the underground extension of the pipe. Is particularly suitable for trenchless laying of large and medium pipe diameters. Has the comprehensive functions of economy, high efficiency and environmental protection. The technology has the advantages of no excavation of the ground, no removal, no damage to ground buildings, no influence on traffic, no damage to the environment, no influence on construction by weather and environment, no influence on section difference deformation of pipelines, time saving, high efficiency, safety and low comprehensive cost.
The technology is widely applied to trenchless laying of various pipelines such as urban underground water supply and drainage pipelines, natural gas and petroleum pipelines, communication cables and the like in coastal economically developed areas of China. It can cross roads, railways, bridges, mountains, rivers, straits and any buildings on the ground. By adopting the technology for construction, a large amount of expropriated land removal cost can be saved, the environmental pollution and the road blockage can be reduced, and the economic benefit and the social benefit are remarkable.
The pipe-jacking construction is a construction method of underground pipelines developed after shield construction, does not need to excavate a surface layer, and can pass through highways, railways, rivers, ground buildings, underground structures, various underground pipelines and the like. In the pipe jacking construction, by means of the thrust of a main jacking oil cylinder, an inter-pipeline relay and the like, a tool pipe or a heading machine is pushed from a working well through a soil layer until the tool pipe or the heading machine is hoisted in a receiving well. Meanwhile, the pipeline following the tool pipe or the heading machine is buried between the two wells, so that the construction method for laying the underground pipeline without excavating is realized.
In the existing pipe jacking technology, various connecting parts are mostly adopted for connecting the pipe jacking and the pipe jacking, and the connecting parts are additionally arranged parts, so that on one hand, the processing cost is increased, and the processing precision and complexity are increased; on the other hand, the cooperation between parts has also increased the construction degree of difficulty, has reduced the efficiency of construction, and the structure is more complicated, and the overall stability and firm crushing resistance of push pipe also can reduce, and this is unfavorable for underground push pipe construction again.
