Embodiment Construction

[0032] In order to better describe the present invention, a method for controlling water gushing disasters in fissures of easily weathered rock slopes according to the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Depend on figure 1 Shown in the present invention a kind of easy weathering rock slope fissure water gushing disaster control method adopts the collection, guiding and drainage, anti-blocking system plane top view and combined figure 2 , image 3It can be seen that the water gushing collection system adopted in the present invention includes the left and right water guide walls 3 respectively arranged on the outer edges of both sides of the water gushing part of the 9 fissures of the easily weathered rock slope and the downstream wall of the 9 water gushing parts of the easy weathering rock slope. The water retaining wall 11; the anti-silting system of the sump pit adopted in the present inventio...

Abstract

The invention discloses an easily weathered rock slope crack water burst disaster treatment method. Left and right water guide walls (3) and a water retaining wall (11) form an opening trapezoid; a water collecting pit (6) is excavated near the inner side of the water retaining wall (11); a section of drainage pipe (7) is embedded in the water collecting pit (6); the upper part of a fixed anchor rod (4) is vertical ribs of reinforced concrete of a water guide wall (3), the water retaining wall (11) and the water collecting pit (6); a pit internal protective net (5) is arranged at the top of the water collecting pit (6); a wall top protective net (2) is arranged at the tops of the left and right water guide walls (3) and the water retaining wall (11); and the pit internal protective net (5)is arranged at the top of the water collecting pit (6). Water bursting from slope rock cracks can be effectively collected to solve the problem of failure caused by small change of water burst outletpositions of the rock cracks; through triple protective nets, the problem of blocking the water collecting pit due to rock weathering can be prevented; and the drainage pipe can effectively drain thewater bursting from slopes to solve the problem of reduced strength due to infiltration of upper rock crack water into lower rocks of the slopes.

Description

technical field [0001] The invention relates to a rock slope fissure water gushing disaster control technology, which is suitable for various types of slope fissure water gushing (ground water), especially for the treatment of water gushing from fissures in easily weathered rock slopes. Background technique [0002] The joints and fissures in the broken rock slope are intricate and poor in stability. Groundwater, rainfall and other water flows into the slope body to scour the weak structural surface, and the slope maintenance work is facing a severe test. For high water-rich slopes, it is necessary to take effective water prevention and control engineering to control the water inflow of the slope, [0003] With the continuous development of mineral resources and the continuous expansion of the scale of geological and mining engineering, the problem of water gushing from rocky slope fissures as a disaster factor has become increasingly prominent, and the stability of many ro...
