Embodiment Construction

[0023] The following description illustrates specific embodiments of the invention sufficiently to enable those skilled in the art to practice and reproduce it.

[0024] Such as figure 1 Shown is the construction schematic diagram of rammer pipe in the present invention.

[0025] Pipe rammer construction equipment, including: pipe rammer 1, guide rail 3, height adjustment device 4.

[0026] The pipe rammer 1 is used to advance the steel casing 2. Its structure includes: a pipe rammer 11, a connecting rod 12 and power equipment. The rear end of the connecting rod 12 is connected to the power equipment, and the front end transmits the impact force to the pipe rammer 11. The pipe rammer 11 pushes the steel sleeve 2 to advance, so that the steel sleeve 2 cuts the soil layer. After a plurality of steel sleeves 2 are welded and pass through the soil layer in turn, they pass through the pipeline in the steel sleeve 2 to complete the pipeline crossing construction.

[0027] In order...

Abstract

The invention discloses pipe ramming construction equipment, which comprises a pipe ramming machine, a guide rail and a height adjusting device; the pipe ramming machine is provided with a pipe ramming hammer and a connecting rod which are connected with each other; the guide rail is arranged on the lower portion of the pipe ramming hammer and used for supporting the pipe ramming hammer; and the height adjusting device is arranged between the pipe ramming hammer and the guide rail and used for supporting the pipe ramming hammer, so that the pipe ramming hammer and a steel sleeve are located on the same axis, and deviation of the pipe ramming hammer is prevented. The invention further discloses a pipe ramming construction method. The pipe ramming construction equipment provided by the invention can ensure that the steel sleeve is orderly and accurately tamped into a soil layer in the pipe tamping construction process, is beneficial to improving the working efficiency, and ensures the construction quality.

Description

technical field [0001] The invention belongs to the technical field of pipeline construction, and in particular relates to a pipe ramming construction method and equipment thereof. Background technique [0002] The rammed pipe construction method is a technology in which the steel pipe to be laid is directly rammed into the ground along the set route with a pipe ramming hammer to realize trenchless pipe laying. Its working principle is that the impact force generated by the ramming hammer under the drive of compressed air directly acts on the rear end of the steel pipe, cuts into the soil through the front end of the steel pipe, and overcomes the friction between the soil layer and the pipe body. , high-pressure water flow, manual soil removal or auger drill pipe and other methods to discharge the soil core in the pipe. The rammed pipe method has strong adaptability to the ground and can be used in any soil layer. The pipe laying diameter range is large and the construction...
