City utility tunnel

Abstract

The invention discloses a city utility tunnel. The city utility tunnel comprises tunnel unit bodies. T-shaped installation grooves are formed in both the two sides of the interior of each tunnel unitbody. A placement opening groove is formed in the upper surface of each T-shaped installation groove. A positioning hole is formed in the front end of the inner side surface of each T-shaped installation groove. A T-shaped installation block is in sliding connection with the inner side surface of each T-shaped installation groove. Both the two sides of the surface of the front end of each T-shapedinstallation block are connected with the inner side surface of the corresponding positioning hole through positioning rods in a sliding manner. The surface of the front end of each T-shaped installation block is connected to an opening in the front end of the interior of the corresponding T-shaped installation groove through a connecting block in a sliding manner. An installation screw is arranged on the surface of the front end of each connecting block. An installation nut is in thread connection with the outer surface of each installation screw. The rear side surface of each installation nut is connected to the front end of the inner side surface of each tunnel unit body through a top block in a sliding manner. With the city utility tunnel, convenience and stability of usage can be greatly improved, and safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of urban construction, in particular to an urban comprehensive pipe gallery. Background technique [0002] The comprehensive pipe corridor is the comprehensive corridor of underground urban pipelines, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports and detection systems. Implement unified planning, unified design and management, due to urban management and operation. [0003] Most of the existing integrated pipe galleries are made of pipe gallery units suitable for concrete pouring, and there are still some shortcomings in actual use. For example, in order to ensure the stability of the pipeline, it is generally necessary to install pipe brackets inside the integrated pipe gallery , but the existing structural form is to splice the pipe gallery first,...

Problems solved by technology

[0003] Most of the existing integrated pipe galleries are made of pipe gallery units suitable for concrete pouring, and there are still some shortcomings in actual use. For example, in order to ensure the stability of the pipeline, it is generally necessary to install pipe brackets inside the integrated pipe gallery , but the existing structural form is to splice the pipe gallery first, and then rotate and install it again. Not only is the operation complicated, it is inconvenient to manage, but it is also easy to damage the structural strength of the pipe gallery unit, the use effect is not ideal, and the safety is poor , it is not convenient to fix and support the pipes, and because the comprehensive pipe gallery is located under the ground, it needs to ventilate the interior, and the existing structure does not have ventilation pipes for ventilation, which not only has poor heat dissipation, but also easily causes internal air pollution. Turbidity affects the health of maintenance personnel, and the separate ventilation pipes are likely to cause rainwater to flow back, affecting internal safety and stability, and the use effect is not ideal
