Abstract
The utility model discloses a side slope drainage system, including setting up in the inside drainage hole of side slope, be provided with the wash port on the drainage hole, the sliding surface fed through at the bottom of ear hole and side slope were passed through to the drainage hole, still was provided with the first guide hole that is used for surveying drainage hole rimrock stone thickness on the drainage hole. A side slope drainage system, is through the setting in first guide hole and ear hole, has guaranteed the country rock geological conditions of the feasibility and the drainage hole cavitation of wash port, can accurate definite drainage hole axis position, the drainage hole can be done simultaneously in the ear hole, and groundwater in the discharge slip mass improves the stability of slip mass, the monitoring hole still can be done simultaneously in the ear hole, through the installation monitoring instrument, lasts ground deep deformation monitoring, in addition, the simple structure of this system, it is with low costs, easily promote.
Description
Technical field
The utility model belongs to slope project technical field, relates to a kind of slope drainage system.
Background technology
Stability of slope is the Focal point and difficult point problem often faced in engineering construction, is the key factor whether engineering constraint project is set up, and in the Large Infrastructure Projects such as water conservancy and hydropower, Rail Highway building project, is all the engineering problems needing primary study.In stability of slope, important link is the design of drainage system, and the impact of water Slope Stability is very large.If drainage measure is unsound, side slope is possibility unstability just, therefore must take rationally effective drainage system.
Existing slope drainage system is typically employed in the measure that drainage tunnel and drain hole are arranged in below side slope deep implication face, reduce the groundwater table of more than slide plane, reach the water pressure reduced on sliding surface, improve the object of sliding mass and slide plane mechanics parameter, and then improve whole slope stability.In order to ensure effective realization of drainage measure, higher requirement is proposed to the distance of drainage tunnel distance slide plane, distance is too near, and then drainage tunnel wall rock geology condition is poor, and cavitation condition is poor, stable problem is comparatively outstanding, also can bring the increase of cavern support engineering quantity simultaneously; Apart from too far away, drain hole is difficult to penetrate slide plane and enters sliding mass, does not have the object of discharging underground water in sliding mass, also can cause the waste of drain hole engineering quantity simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of slope drainage system, by the setting in pilot hole and ear hole, reaches the object of discharging underground water in sliding mass.
The technical scheme that the utility model adopts is: a kind of slope drainage system, comprise the drainage tunnel being arranged on side slope inside, drainage tunnel is provided with drain hole, and drainage tunnel is communicated with sliding surface at the bottom of side slope by ear hole, drainage tunnel is also provided with the pilot hole for detecting drainage tunnel hole rimrock stone thickness.
Feature of the present utility model is also:
Drain hole axially arranges one group at interval of 2.5-3.5m along drainage tunnel, often organizes drain hole and is evenly provided with 3 along drainage tunnel circumference.
Ear hole length is 8-12m, arranges one at interval of 90-110m.
Pilot hole length is 3-10m, arranges one at interval of 9-11m.
The beneficial effects of the utility model are: a kind of slope drainage system, by the setting in pilot hole and ear hole, ensure that the feasibility of drain hole and the wall rock geology condition of drainage tunnel cavitation, can determine drainage tunnel axis direction more accurately; Drainage tunnel doublely can be done in ear hole, discharges underground water in sliding mass, improves the stability of sliding mass; Monitoring hole also doublely can be done in ear hole simultaneously, by installing monitoring instrument, carries out deep deformation monitoring constantly; In addition, this system architecture is simple, and cost is low, is easy to promote.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of a kind of slope drainage system of the utility model, as shown in Figures 1 and 2, comprise the drainage tunnel 1 being arranged on side slope inside, drainage tunnel 1 is provided with drain hole 4, drainage tunnel 1 is also provided with the pilot hole 3 for detecting drainage tunnel hole rimrock stone thickness, drain hole 4 interval 2.5-3.5m is arranged, ear hole 2 length is 8-12m, arrange one at interval of 90-110m, pilot hole 3 length is 3-10m, arranges one at interval of 9-11m; As shown in Figure 3, drain hole 4 axially arranges one group at interval of 2.5-3.5m along drainage tunnel 1, often organizes drain hole 4 and is evenly provided with 3 along drainage tunnel 1 circumference; As shown in Figure 4, drainage tunnel 1 is communicated with sliding surface at the bottom of side slope by ear hole 2.
During use, judge the distance of sliding surface at the bottom of the thickness of drainage tunnel hole rimrock stone and drainage tunnel and side slope respectively by pilot hole 3 and ear hole 2, and then determine the position of drainage tunnel 1, the underground water in the body of slope is got rid of by drain hole 4; In addition, drainage tunnel doublely can be done in ear hole 2, discharges underground water in sliding mass.
A kind of slope drainage system of the utility model, by the setting in pilot hole and ear hole, ensure that the feasibility of drain hole and the wall rock geology condition of drainage tunnel cavitation, can determine drainage tunnel axis direction more accurately; Drainage tunnel doublely can be done in ear hole, discharges underground water in sliding mass, improves the stability of sliding mass; Monitoring hole also doublely can be done in ear hole simultaneously, by installing monitoring instrument, carries out deep deformation monitoring constantly; In addition, this system architecture is simple, and cost is low, is easy to promote.
