Embodiment Construction

[0029] The construction steps of this embodiment include:

[0030] (1) Measurement and setting-out

[0031] Arrange temporary benchmarking points and pipeline axis control piles, and set up central piles at intervals of 20m during construction setting-out, and set central piles at inspection wells.

[0032] (2) Construction of working well

[0033] Install reinforced concrete prefabricated slabs in the slots reserved at the top of the working well, and the slots must be filled with grout. Build a brick wall at the reserved opening of the prefabricated slab. All bricks should be soaked in water. During the masonry, they should be fully paved and crowded, and built up and down. The thickness of the horizontal mortar joints and the width of the vertical mortar joints should be uniform, and there should be no vertical joints . When building inspection wells, steps should be installed synchronously, and the positions should be accurate. After the steps are installed, the steps s...

Abstract

The invention discloses a drain pipe jacking construction method. The method is characterized by comprising the following steps of: (1) surveying and setting out; (2) constructing in a working shaft; (3) installing an assembly thrust wall; (4) installing guide rails; (5) installing a main jack; (6) installing an oil pump; (7) installing jacking iron; (8) constructing and sealing inside and outside the tunnel; (9) jacking pipelines: immediately starting jacking the machine head after dismantling a sealed door, and starting a slurry adding system to inject slurry after jacking the machine head by 300mm; and (10) removing oil. The method has the advantages of fast construction progress and obvious social benefits.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a drainage pipe jacking construction method. Background technique [0002] During the construction of drainage pipe jacking, the soil around the pipe body is greatly disturbed, it is difficult to maintain the stability of the excavation surface, and the ground subsidence caused during the construction process is also relatively large, which is likely to affect various underground pipelines, road traffic and ground buildings. Safety. If the drainage pipe properly handles the lateral soil pressure and groundwater pressure of the excavation surface during the jacking construction process, it can effectively control the stability of the soil and ensure the safety of various ground environments. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a drainage pipe jacking construction method. [00...
