Embodiment Construction

[0019] A protection device for sinkholes in karst depressions (see attached figure 1 ), which includes a maintenance body 1, a drainage ditch 2 and a top cover plate 3 of the drainage ditch. The maintenance body 1 is arranged on the periphery of the sinkhole 4, the drainage ditch 2 is located below the maintenance body 1, and the drainage ditch 2 extends from the outside of the maintenance body 1 to the inside, and finally connects with the sinkhole 4, and the top cover plate 3 is above the drainage ditch 2.

[0020] During construction, at first the trench is excavated, and the drainage ditch 2 is connected with the sinkhole 4 at the lowest point of the depression. Drainage ditch 2 is a masonry rubble structure, the top of which needs to reserve the position of top cover plate 3, and the bottom of the ditch maintains a longitudinal slope of 1% to 3% along the direction of the sinkhole, which is used to drain the water collected in karst depression 7 into In the sinkhole. Th...

Abstract

The invention discloses a protective device for a karst depression sinkhole. The protective device comprises a fence (1) surrounding the sinkhole (4), wherein a drainage ditch (2) is arranged below the fence (1) and connected with the sinkhole (4); a top cover plate (3) is arranged above the drainage ditch (2); the fence (1) is a rotor, the central axis of the fence (1) is the center of the sinkhole (4), and the cross section of the fence (1) is shaped like an isosceles trapezoid with the narrow upper bottom and wide lower bottom. The engineering problems that as a lot of waste earthwork slags roll to the center of a depression during excavation of a karst depression project, a depression sinkhole is blocked undoubtedly and drainage is not smooth are solved effectively.

Description

technical field [0001] The invention belongs to the field of sinkhole protection, in particular to a protection device structure for sinkholes in karst depressions. Background technique [0002] Karst refers to the dissolution of water (surface water and groundwater) on soluble rocks, and karst depressions are a closed negative topography produced by rock dissolution. Depressions are often round or oval, surrounded by low mountains, hills and peak forests; the bottom is generally flat and covered with loose deposits. There are often sinkholes at the bottom of the depression, which are vertically developed caves with a width ranging from a few centimeters to more than 10 meters, and are the main channels for surface water to flow into underground rivers. In general, the drainage capacity of depression sinkholes can adapt to the local precipitation and precipitation intensity. Especially in the rainy season, the depression sinkhole is the most important drainage channel. ...
