Embodiment Construction
[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0046] This embodiment discloses an immersed tube inspection well, such as figure 1 As shown, it includes a cylindrical wellbore 1, and the wellbore 1 is composed of a lower well body 13, a middle well body 12 and an upper well body 11 arranged in sequence from bottom to top. The upper end of the upper well body 11 is poured with an inspection port 111, and the side wall of the middle well body 12 is formed with two connection ports 121 matching with the target pipelines on both sides, and the bottom of the lower well body 13 is formed with a blade foot 131, and Add steel plates for reinforcement. The tops of the lower well body 13 and the middle well body 12 are formed with an upper gap 14 extending obliquely downward, while the bottoms of the middle well body 12 and the upper well body 11 are formed with a lower gap 15 that matches the upper gap 14. The u...

The invention relates to an inspection well, and aims to provide an immersed tube type inspection well and a construction method thereof. The immersed tube type inspection well comprises a cylinder-shaped shaft, wherein blade feet are arranged at the bottom of the shaft; a guide hole penetrating vertically downwards is formed in the shaft, and a positioning column capable of vertically downwards entering a soil layer is slidably connected in the guide hole; and the shaft is provided with flushing holes penetrating downwards from the inner wall to the blade foot positions, and high-pressure flushing devices are arranged at the opening positions of the upper ends of the flushing holes. When the shaft is in a balanced state, the positioning column is vertically inserted downwards into the soil layer for positioning, and then soil at the bottom of the shaft is continuously excavated to enable the shaft to sink, while the relative sliding between the positioning column and the guide hole has a guiding effect, so that the shaft can keep to be in vertical direction not inclined under the action of the positioning column; and the stability of the shaft is improved, and the construction deviation is reduced.
Description
technical field [0001] The invention relates to an inspection well, in particular to an immersed tube type inspection well and a construction method thereof. Background technique [0002] The inspection well is set up for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage discharge, communication, cable TV, gas pipes, and street lamp lines, and is convenient for installation. It is generally installed at the intersection of pipelines, turning places, pipe diameter or slope changes, and at certain distances on straight pipe sections, which is convenient for regular inspection of ancillary structures. [0003] At present, the Chinese patent document with the authorized notification number CN203701145U in the prior art discloses a concrete component of an underground pipe network inspection well, including a well cover, a concrete upper neck, a concrete middle section, and a concrete base component. The mouth of the concret...
