Problems solved by technology
[0003] However, there are some problems and deficiencies in the non-excavation directional drilling construction: (1) The strength of the soil body decreases due to the excavation of holes, resulting in surface subsidence; (2) The grouting reinforcement process is cumbersome and the grouting is not uniform enough

Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] like figure 1 As shown, the present invention includes an integrated pipeline for transportation and grouting, which includes a pipeline main body 1 , a grouting nozzle 2 and a slide rail 3 . The grouting nozzle 2 has three vertical rows, and every row of the grouting nozzle 2 is connected to the upper discharge grout hole 3-2 of the slide rail 3. The slide rail is arranged on the surface of the pipeline, and the grouting nozzle 2 is integrated with the upper half 3-1 of the slide rail, and can move along the lower half 3-3 of the slide rail.
[0028] like figure 2 As shown, the pipeline main body 1 is composed of a metal pipeline entity 1-1, a transport hole 1-2 and a grouting hole 1-3.
[0029] like image 3 As shown, the grouting nozzle 2 is made up of a telescopic pipe body 2-1 and a spring 2-2. The telescopic pipe body 2-1 can increase the length of t...

The invention discloses a conveying and grouting integrated pipeline and an operation method thereof. A pipeline body is included. A sliding rail is arranged on the upper surface of the pipeline bodyand provided with a grouting spraying pipe. The pipeline body is composed of a pipeline solid body, a conveying hole and a grouting hole. The conveying hole is formed in the hollow part in the pipeline solid body. The grouting hole is formed in the inner wall of the pipeline solid body. The sliding rail is composed of a sliding rail upper half part and a sliding rail lower half part. An upper slurry discharging hole is formed in the sliding rail upper half part and connected with the grouting spraying pipe. A lower slurry discharging hole is formed in the sliding rail lower half part and connected with a grouting hole outlet. The conveying and grouting integrated pipeline is divided into a conveying part and a grouting part, a conveying pipe and a grouting pipe are combined, the construction difficulty is lowered, and construction steps are simplified; and meanwhile, the grouting position is changed, grouting and solidifying start from the hole wall, the problem of ground surface collapsing in the construction process is solved, manpower is saved, and accordingly the purposes of efficiency improving, safety and stability are achieved.
Description
technical field [0001] The invention belongs to the field of underground pipeline engineering, in particular to an integrated pipeline for transportation and grouting and an operation method thereof. Background technique [0002] In recent years, trenchless technology has developed rapidly and has become an extremely important construction method for laying pipelines in cities. Trenchless technology uses technical means such as geotechnical drilling and directional measurement and control, and can cross roads, railways, rivers, and even pass under buildings without excavating the ground to achieve water supply, gas, natural gas, etc. Function is a construction method that can safely and effectively protect the environment, and it occupies a unique advantage in urbanization construction because of its timely, powerful and irreplaceable characteristics. [0003] However, there are some problems and deficiencies in the construction of trenchless directional drilling: (1) due t...
