Maintainable tunnel intelligent waterproof and drainage system and method

Abstract

The invention discloses a maintainable tunnel intelligent waterproof and drainage system and method. The maintainable tunnel intelligent waterproof and drainage system comprises a longitudinal drainage blind pipe, an annular drainage blind pipe, a vertical inspection well, a side drainage pipe, a drainage side ditch, a central drainage ditch, an electronic valve and a computer terminal, wherein the computer terminal is used for receiving and analyzing urban tunnel water pressure load data transmitted by the electronic valve, and an instruction is sent to the electronic valve to control the opening and closing of the electronic valve so as to achieve the balance between the water pressure and the displacement of tunnel engineering. Compared with the prior art, the maintainable tunnel intelligent waterproof and drainage system can complete the switching of three urban tunnel waterproof and drainage modes according to actual requirements of tunnel waterproof and drainage, and the electronic and informatization management of tunnel waterproof and drainage is achieved; the waterproof and drainage requirements during the operation period of a tunnel structure can be met, and the maintenance function is achieved; when the drainage function is impaired, operation maintenance can be conducted by entering the vertical inspection well on the premise that urban tunnel traffic is not affected.

Description

technical field [0001] The invention relates to the field of tunnel waterproofing and drainage, in particular to a maintainable intelligent tunnel waterproofing and drainage system and method. Background technique [0002] Urban tunnels can effectively improve urban traffic efficiency and reduce environmental pollution, which is also in line with the current advocacy of low-carbon life. Due to the particularity of urban tunnels, the existing buildings and vegetation on the ground make urban tunnels face many challenges during operation and maintenance. Water hazards (groundwater, rainfall, etc.) have the most common impact on tunnel engineering safety, and safety problems caused by groundwater account for 58% of the total number of tunnels. When water damage occurs in urban tunnels, it usually leads to a drop in the groundwater level, depletion of surface water sources, soil erosion, vegetation destruction, and ground subsidence. Solving tunnel water problems can effective...

AI Technical Summary

Problems solved by technology

[0003] In order to reduce the probability of water disasters, three types of waterproof and drainage systems are mainly adopted for urban tunnels in my country: (1) The drainage type or drainage and self-drainage system mainly based on drainage and drainage is adopted, that is, the urban tunnel support structure is reduced through drainage; This method can effectively reduce the groundwater level, but the resulting damage to the ground vegetation is difficult to recover; (2) The all-inclusive waterproof system isolates the seepage of the ground from the supporting structure of the urban tunnel, through Improve the waterproof capacity of the support structure to realize the waterproof function of urban tunnels, but under the long-term action of water pressure load, the support structure is prone to cracks and cause water leakage; The waterproof method allows part of the groundwater to be discharged, which can not only ensure the safety of the structure, but also reduce the water pressure behind the lining, but this method is difficult to achieve a dynamic balance between the relationship between water pressure and displacement, so it is difficult to achieve the ideal state

The above three urban tunnel waterproofing and drainage modes all have certain disadvantages, and the amount of waterproofing and drainage is difficult to control. Therefore, an intelligent urban tunnel waterproofing and drainage system is needed

[0004] In the existing urban tunnel waterproof and drainage system, it is not yet possible to switch between the 3 waterproof and drainage modes on demand

In addition, during the operation and maintenance of urban tunnels in the later stage, the inspection shaft of the drainage system is usually located in the town center of the urban tunnel pavement. During the maintenance process, the personal safety of the maintenance personnel is difficult to guarantee, and the passage of vehicles in the tunnel will also be affected.
