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
The invention belongs to sinkhole protection field, particularly relate to the protective device structure of karst depression sinkhole.
Background technology
Karst refers to that water (surface water and groundwater) is to the corrosion of solublerock, and karst depression is a kind of closed negative land form produced due to rock corrosion.Depression is often rounded or oval, and surrounding is low mountains and hills and peak forest; Bottom is general comparatively smooth, covers rickle.Often having sinkhole bottom depression, is the cave vertically developed, width number centimetre to more than 10 rice not etc., be the central core of circulation that surface water flows into subterranean stream.Generally, the drainability of depression sinkhole can adapt to local amount of precipitation and precipitation intensity.Special in rainy season, depression sinkhole is most important drainage channel especially.
But when carrying out geotechnical engineering excavation in karst depression, due to the closure in depression, the cubic metre of earth and stone excavated out can only first to depression internal discharge.Adding the various harmful engineering ground bodies etc. such as the rock abrupt slope of avalanche block stone accumulation body slope, off-load fracture development in depression and small-sized karst cavity very to grow, also can further increase a cubic meter waste when processing these unfavorable geologic body.Therefore; during geotechnical engineering excavation and when not yet completing at other drainages, if do not protected depression sinkhole, all kinds of wastes rolled to center, depression certainly will cause the blocking of depression sinkhole; have a strong impact on the outlet capacity that disappears of sinkhole, the waterlogging problem during even causing excavation.Therefore, how to provide a kind of simple, effective and durable sinkhole protective device, to protect depression sinkhole not blocked, the problem must considered when being karst depression engineering excavation.
Summary of the invention
The technical problem to be solved in the present invention: a kind of karst depression sinkhole protective device is provided, during to solve karst depression engineering excavation due to a large amount of cubic metre of earth and stone waste tumble to depression central authorities, the blocking of depression sinkhole certainly will be caused and impeded drainage time the engineering problem that faces.
Technical scheme of the present invention is: a kind of karst depression sinkhole protective device, comprises the maintenance body being arranged on sinkhole periphery, and safeguard below body to be gutter, gutter is connected with sinkhole, is top blind flange above gutter.
Describedly safeguard that body is the rotary body that is axle with the central axis of sinkhole.
Describedly safeguard that the transverse shape of body is the isosceles trapezoid of the narrow lower bottom width of upper base.
Describedly safeguard that body itself is built by laying bricks or stones by rubble mortar and form.
Described gutter is mortar flag stone or concrete structure.
Upper end, described gutter is provided with bearing, and top blind flange placed by bearing, top blind flange two side ends and Jian You shrinkage joint, gutter.
Ditch top blind flange structure is reinforced concrete structure.
Primary structure of the present invention comprises the top blind flange safeguarded above body, gutter and gutter.
Gutter is mortar flag stone or concrete structure, and its cross dimension is determined according to the discharge collected bottom heavy rain depression in season, and size can meet arranges requirement into sinkhole in time by collecting current.
Gutter top blind flange is reinforced concrete structure, and intensity meets the requirement that body is safeguarded on carrying top.Because top blind flange can ensure that inside, ditch does not fall into foreign material, thus ensure that the smoothness of draining.
Safeguard that body is a rotary body, its face shaping is similar one circular, the center of circle is the center of sinkhole, only the cross section of annulus is changed from circle and has been done other cross sectional shapes, such as safeguard that the section configuration of body is the isosceles trapezoid of the narrow lower bottom width of a upper base, inner space is a handstand shape round platform wide at the top and narrow at the bottom.Safeguard that body itself adds masonry of cement mortar by rubble and forms.
The present invention safeguards body by arranging around sinkhole, and designing and arranging ditch is connected with sinkhole, thus when solving karst depression engineering excavation due to a large amount of cubic metre of earth and stone waste tumble to depression central authorities, the blocking of depression sinkhole certainly will be caused and impeded drainage time the engineering problem that faces.
Accompanying drawing explanation
Fig. 1 is floor map of the present invention;
Fig. 2, Fig. 3 are sectional schematic diagram of the present invention.
Detailed description of the invention
A kind of karst depression sinkhole protective device (see accompanying drawing 1), it comprises safeguards body 1, gutter 2 and gutter top blind flange 3.Safeguard that body 1 is arranged on sinkhole 4 peripheral, safeguard below body 1 to be gutter 2, gutter 2, from safeguarding that the outside of body 1 extends to inside, is finally connected with sinkhole 4, is top blind flange 3 above gutter 2.
During construction, first excavate groove, carry out gutter 2 at depression lowest part and be connected with sinkhole 4.Gutter 2 is mortar flag stone structure, and its top need reserve the position of top blind flange 3, and bottom of trench keeps the longitudinal gradient gradient of 1% ~ 3% along sinkhole direction, enter in sinkhole for the water collected by karst depression 7.Gutter 2 transverse shape is shown in accompanying drawing 3.
After having constructed in gutter, then arrange top blind flange 3 at top, gutter 2, top blind flange 3 is reinforced concrete structure.Bearing 5 and the shrinkage joint 6 of 20 millimeters thick are set between draining structure 2 and top blind flange 3.Gutter top blind flange 3 is shown in accompanying drawing 3 with the connected mode of draining structure 2.
Top blind flange 3 is constructed complete, then carries out safeguarding building by laying bricks or stones of body 1.To build by laying bricks or stones for the center of circle (axis of rotary body) with the center of sinkhole 4 and safeguard body 1, inner edges base diameter is 10 meters.The shape of cross section safeguarding body 1 is isosceles trapezoid, bottom width 1 meter on it, and lower bottom width 8.5 meters is high 3 meters.Safeguard that body 1 adopts rubble mortar to build by laying bricks or stones, rubble particle diameter is not less than 500 millimeters, and the label of masonry mortar is M7.5.Maintenance body 1 inner space of finally having built by laying bricks or stones is a handstand shape round platform wide at the top and narrow at the bottom, sees accompanying drawing 2.
