Collecting and discharging system for crack water burst of eugeogenous rock slope

Abstract

The invention discloses a collecting and discharging system for crack water burst of an eugeogenous rock slope. The collecting and discharging system for crack water burst of the eugeogenous rock slope is formed by combining a water collecting system, a water collecting pit anti-blocking system and a water discharging system, wherein the water collecting system comprises left and right water guidewalls (3) and a water blocking wall (11); the left and right water guide walls (3) are respectively distributed and arranged at the outer edges of the two sides of a crack water burst position of theeugeogenous rock slope (9); the water blocking wall (11) is arranged at the downstream of the water burst position of the eugeogenous rock slope (9); the water collecting pit anti-blocking system comprises a slope protection net (1), an in-pit protection net (5) and a wall top protection net (2); the water discharging system comprises a water discharging pipe (7); an upper opening of the water discharging pipe (7) is connected and communicates with the water collecting pit (6); and a lower opening of the water discharging pipe (7) communicates with a downstream intercepting water dischargingditch or a mining pit water discharging pool (10). The collecting and discharging system has the advantages that the structure is compact; the service life is long; stability and firmness are realized; the implementation is convenient; the concentrated discharging of water burst from rock cracks can be effectively realized; the slope flushing is prevented; the persistent stability of the slope isimproved; and the collecting and discharging system can be applied to slope water burst governance engineering in industries of surface mines, building, water conservancy, traffics and the like.

Description

technical field [0001] The present invention relates to a rock slope fissure water removal technology, in particular to an easily weathered rock slope fissure water collection and drainage system and its construction method, which is suitable for all types of slope fissure water gushing (groundwater), especially for easily weathered rock slope fissures The treatment of water gushing from many fissures on the weathered rock slope surface can be popularized and applied in slope water gushing control projects in open-pit mines, construction, water conservancy, transportation and other industries. Background technique [0002] Rock mass fissure water can reduce the shear strength of rock mass, which is one of the main factors for slope failure. This phenomenon is more prominent in rocky slopes that are prone to weathering, and draining groundwater from slopes is an important means to increase slope stability. . In the process of open-pit mining, as the mining pit moves down, wa...

Problems solved by technology

Patent ZL201820898669.0 involves groundwater collection and drainage technology on side (landslide) slopes, but the system is complicated, the engineering quantity is large, and the cost is high. It is mainly suitable for landslide control, not suitable for fissure water collection and drainage of weathered rock slopes
