Embodiment Construction

[0010] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0011] Please refer to figure 1 , the pipe jacking construction structure includes a working well 1 and a closing well 2, and two opposite sides of the working well 1 are provided with a back 3, a hydraulic cylinder 4, a jack 5 and a top iron 6 in sequence, and the top iron 6 is close to the preset On the side of the excavation channel, the back 3 is attached to the opposite side of the side of the pre-excavation channel. The hydraulic cylinder 4 is provided with a reading meter, which can detect the pressure at any time. When excavating the channel a between the working well 1 and the closing well 2, every time a part of the channel a is excavated, the prefabricated pipeline is pushed into the excavated channel a with the top iron 6, and then the excavation is continued, and the top iron 6 is retracted. Install the pre...

Abstract

The invention discloses a pipe-jacking construction structure which comprises a working well and a closing well. A back, hydraulic oil cylinders, jacks and jacking iron are sequentially arranged on the two opposite sides of the working well. The jacking iron is attached to a pre-excavated channel side, and the back is attached to the opposite side of the pre-excavated channel side. The pipe-jacking construction structure is convenient to excavate and convenient to use and operate, and collapse of an excavated channel can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a pipe jacking construction structure. Background technique [0002] The traditional excavation technology is to manually install prefabricated pipes into the excavated channel, which is labor-intensive, inefficient and dangerous. Contents of the invention [0003] The purpose of the present invention is to provide a pipe jacking construction structure, which is convenient for excavation, convenient to use and operate, can effectively avoid the collapse of the excavated channel, and reduces labor intensity and danger. [0004] In order to achieve the above object, the present invention provides a pipe jacking construction structure, which includes a working well and a shut-off well. Two opposite sides of the working well are provided with a back, a hydraulic cylinder, a jack and a top iron in sequence. The top iron is close to the pre-opening On the side of the exc...
