Embodiment 1

[0019] like figure 1 and figure 2 As shown, a device that uses solar energy to reduce the water content of the slope body includes a heat-insulating steel pipe 8 that is inserted into the slope body drainage ditch 7 and has a water vapor overflow port 6 at the top. The lower section of 8 is evenly distributed with a plurality of preset holes 9, and the 8 sections of heat-insulating steel pipes with a plurality of preset holes 9 are wrapped with a geotextile layer 10. A water-stop rubber ring 12, a heating device 17 is installed in the heat transfer conical tube 13, and a moisture content monitoring probe 15 is installed outside the heat transfer conical tube 13;

[0020] The solar panel 3 , the master switch 2 , the control module 1 and the moisture content monitoring probe 15 are connected in series through the wire 5 to form a closed loop, and the heating device 17 is electrically connected to the control module 1 .

[0021] The solar panel 3 is installed on the heat insu...

Embodiment 2

[0030] like image 3 As shown, a method for reducing the water content of the slope by using the device, the master control switch 2 is turned on, the water content monitoring probe 15 works, and the monitoring signal is transmitted to the control module 1. If the water content of the rock and soil at the monitoring position is higher than the threshold value, control The module 1 is connected to the working branch of the heating device 17, the heating device 17 works and heats, the water evaporates, overflows through the water vapor overflow port 6 on the top of the heat insulating steel pipe 8, and the water vapor solidifies and gathers and drips in the drainage ditch 7, and is discharged outside the slope, thereby achieving For the purpose of reducing the moisture content of the rock and soil mass of the slope, continue to heat the rock and soil mass until the moisture content of the monitored rock and soil mass is lower than or equal to the threshold value, and the control ...

Abstract

The invention discloses a device for reducing a slope water content by solar energy. The device comprises a thermal insulation steel pipe inserted in a slope drainage ditch and provided with a water vapor overflow port in the upper part; a solar panel is mounted at the upper end of the thermal insulation steel pipe; multiple preset holes are uniformly distributed in the lower section of the thermal insulation steel pipe; the thermal insulation steel pipe section provided with the multiple preset holes is wrapped with a geotechnical cloth layer; the lower end of the thermal insulation steel pipe is in threaded connection with a heat transfer conical pipe; a heating device is mounted in the heat transfer conical pipe; a water content monitoring probe is mounted out of the heat transfer conical pipe; the solar panel, a main control switch, a control module and the water content monitoring probe are serially connected to form a closed loop; and the heating device is electrically connected with the control module. The device for reducing the slope water content by the solar energy and a method thereof can solve the problems of high construction difficulty, long period and high cost in traditional slope drainage projects, and is convenient and fast in implementation, low in cost, low in influence on the slope stability in the construction process and simple in later maintenance.

Description

technical field [0001] The invention relates to the field of reducing the water content of a slope body, in particular to a device and a method for reducing the water content of a slope body by using solar energy. Background technique [0002] Water is one of the main causes of slope instability. The existing slope reinforcement drainage system includes: surface drainage works and underground drainage works. Surface drainage projects often use intercepting ditches and drainage ditches. According to the location of the slope, engineering geology and hydrogeological conditions, etc., underground drainage can choose blind ditch, drainage hole, drainage well, drainage hole, large-diameter tube well, water collection well, horizontal drainage pipe or drainage cut-off groove and other schemes. [0003] The purpose of surface drainage is to maximize the drainage of rainwater from the surface and prevent it from seeping into the slope; the purpose of underground drainage is to min...
