Open-excavation underground pipe gallery bed

Abstract

The invention discloses an open-excavation underground pipe gallery bed, and belongs to the field of underground construction engineering. The open-excavation underground pipe gallery bed specificallycomprises a gallery bed upper arc surface, a gallery bed upper plane, a gallery bed outer upper vertical surface, a gallery bed upper inclined surface, a gallery bed lower inclined surface, a gallerybed lower vertical surface and a gallery bed lower plane which jointly form the open-excavation underground pipe gallery bed, and the gallery bed adopts a high-performance basalt fiber composite ribnovel material for reinforcement and a high-performance concrete for main body underground pipe gallery foundation, so that a natural material is promoted to smoothly and quickly enter an open-excavation underground pipe gallery main body, the pipe gallery installation construction problem that the natural material is difficult to enter the open-excavation underground pipe gallery main body is solved, the pressure average degree of the underground pipe gallery main body is greatly improved, and the long-term service life of the underground pipe gallery main body is greatly prolonged.

Description

technical field [0001] The invention belongs to the field of underground construction engineering, in particular to an open-cut underground pipe gallery gallery bed. Background technique [0002] The underground pipe corridor is a comprehensive corridor for the comprehensive management and operation of various underground pipelines in the city. It integrates all pipeline facilities such as water supply, drainage, heating, gas, electricity, and communication, and sets up special inspection and maintenance channels, which can effectively reduce urban traffic. Comprehensive operation and management costs. At present, the main body of the underground pipe gallery is generally made of reinforced concrete. Due to the corrosion of steel bars, the service life of the main body of the concrete pipe gallery is short, resulting in a design service life of 100 years for the main body of the pipe gallery.

AI Technical Summary

Problems solved by technology

At present, the main body of the underground pipe gallery is generally made of reinforced concrete. Due to the corrosion of steel bars, the service life of the main body of the concrete pipe gallery is short, resulting in a design service life of 100 years for the main body of the pipe gallery.

If it is scrapped and replaced when it is due, the cost of dismantling and rebuilding the pipe gallery is close to double the reinvestment. During the period of demolition and reconstruction, the city will not be able to operate normally, and the people will not be able to produce and live normally. Choose a site to build another underground pipe gallery, and the second is to dismantle and rebuild the underground pipe gallery at the original site. No matter what method is used, it will inevitably form a huge pressure on funds, manpower, material resources, and environmental costs, which will bring great pressure to the society. Economic losses

Excessive use will have catastrophic consequences, which will inevitably lead to the paralysis of urban water, electricity, gas, heating, and communication, and the period of demolition and reconstruction will be longer and the loss will be greater

Regardless of whether the existing pipe gallery is rebuilt in advance or demolished and rebuilt, it is a hidden danger that is difficult to solve for future generations.

The more serious problem is that this hidden danger reincarnates every hundred years, and the huge investment with endless troubles will greatly reduce the quality of life of future generations

The only solution is to use natural materials for the main body of the pipe gallery. Due to the high construction cost of the underground pipe gallery construction using the shield machine, most of the underground pipe gallery segments currently use open-cut assembly construction, and the open-cut assembly construction has the disadvantages of pipe gallery construction. The problem that the force on the bottom is difficult to be uniform, especially in areas with complex geology, is more obvious. The problem to be solved by the present invention is to overcome the shortcomings of the existing technology and completely solve the long-term operation safety problem of the main body of the natural material underground pipe gallery
