Directional accelerated crystallization device for tunnel drainage system and use method

Abstract

The invention relates to the technical field of tunnel drainage, and particularly discloses a directional accelerated crystallization device for a tunnel drainage system and a use method.The directional accelerated crystallization device comprises a crystallization pond assembly, a felt layer and a medicine box assembly, the crystallization pond assembly comprises a crystallization pond, and a pond cover is arranged at the top of the crystallization pond; the crystallizing pond comprises a front wall, a rear wall, an outer wall and an inner wall; the medicine box assembly comprises a medicine storage box, a horizontal net-shaped medicine clamping box is arranged at the box bottom of the medicine storage box and is of a double-layer hollow net-shaped structure, the bottom of the medicine storage box is communicated with the net-shaped medicine clamping box, and reaction medicine is placed in the net-shaped medicine clamping box. Influences of temperature, flow velocity, chemicals, shape and surface morphology of the crystallizing pond on tunnel water body crystallization are considered, the assumption of directional crystallization of the tunnel drainage system can be realized, and the tunnel drainage system has the advantages of simple structure and easiness in chemical supplement, cleaning, maintenance and maintenance, can be applied to tunnels put into operation, and also can be applied to tunnel drainage systems. And the method can also be applied to tunnels in a design period.

Description

technical field [0001] The invention relates to the technical field of tunnel drainage, in particular to a directional accelerated crystallization device and a usage method for tunnel drainage systems. Background technique [0002] With the continuous development of the social economy and the continuous advancement of the road construction process, my country's tunnel engineering has achieved considerable development and construction. At present, the number and mileage of construction have ranked first in the world. However, limited by factors such as design level, construction quality, material quality, geological conditions, and operating environment, a large number of tunnels have various degrees of disease after they are put into operation, and tunnel water damage is often the cause of other diseases. [0003] According to statistics, at present, 70% of the tunnels in our country have water leakage, and 30% of them have serious leakage. The decrease in drainage performan...

Problems solved by technology

[0005] Generally speaking, these methods are often limited by the objective conditions such as the tunnel drainage pipe being closed and buried inside the lining, and it is difficult to achieve the expected effect. Some methods will also cause certain damage to the drainage pipe and the surrounding environment of the tunnel.
