Water-rich stratum underground tunnel floating control project renovation system

Abstract

The invention provides a water-rich stratum underground tunnel floating control project renovation system and belongs to the field of building structures. The water-rich stratum underground tunnel floating control project renovation system comprises an underground tunnel main body structure, a tunnel concrete structure bottom plate, an anti-sliding fixing trough plate, a a water stopping curtain stopping wall, a plain concrete cushion, a nonweaven geotextile layer, a sand-gravel reverse filter cushion, graded broken stone, a PVC perforated drainage pipeline, an overflow precipitation recoveryand permeation port, a backfill layer, a waterproof colour striped roll tarpaulin additional layer, a waterproof mortar adhesive base layer and a water collection well; fender piles are arranged on the two sides of the underground tunnel main body structure and on the two sides of the tunnel concrete structure bottom plate; and enclosure structure anti-floating coping crown beams horizontally extending above the underground tunnel main body structure are fixedly arranged at the upper ends of the fender piles. The water-rich stratum underground tunnel floating control project renovation systemhas the beneficial effects that the service life of the underground tunnel structure is indirectly prolonged, collected water resources can be utilized for the second time, the utilization rate of underground water and ground precipitation is increased, the road appearance integrity and beauty are kept, and multi-rebuilding cost of a pavement is reduced.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a control system for an underground tunnel in a water-rich formation to control the floating project. Background technique [0002] With the full development of underground space development and utilization, the application of underground buildings has been very extensive. In areas with a high groundwater level, the buoyancy force generated by groundwater is relatively large, and the anti-floating problem of underground buildings has become a key issue that needs to be controlled during the design and construction of underground structures and buildings. The anti-floating design usually adopts the method of resisting the buoyancy of groundwater by the weight of the structure itself, the upper load of the building and certain anti-floating measures. The risk factor will increase, and the general buoyancy measures will be severely tested. Therefore, it is necessary t...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned existing technical problems, the present invention provides a water-rich strata underground tunnel control and floating engineering renovation system, which can effectively dredge the groundwater around the underground tunnel structure and collect and discharge the water contained under the main structure of the underground tunnel. Avoid damage to the main body of the tunnel caused by water storage outside the underground tunnel, effectively limit the risk of floating up of the underground tunnel structure caused by sudden heavy rain or terrain-affected underground local impermeable layers, help the underground structure resist floating and limit the buoyancy of groundwater while reducing Sudden increase of groundwater occurs occasionally, which can change the hidden dangers of underground tunnels in some areas that cannot meet the design requirements of anti-floating and falling drainage, and prevent water from damaging the underground tunnel structure. It can effectively resist floating and waterproof when encountering geological conditions of enriched water It can prevent the accumulation of flowing water and reduce the corrosion of the underground tunnel structure by flowing water. At the same time, it can prevent the accumulation of groundwater around the underground tunnel structure and cause the accumulated water to freeze or freeze. It can be used as a secondary barrier to protect the main structure of the underground tunnel.
