Description
Technical field
The present invention relates to a kind of deep water discharge technology of side slope, relate in particular to a kind of side slope punishment method that is applicable to that sloping body deformability destruction is influenced by groundwater effect.
Background technology
The landslide disaster that slope deformation destruction forms causes great loss usually for engineering construction and lives and properties.Most landslides are subjected to precipitation affects obvious, are the stability that has reduced side slope because rainfall causes the groundwater table rising.Particularly contain rubble cohesive soil side slope, its stability and WATER LEVEL CHANGES relation is very close.It is the cumulative process of a rainfall that slope body groundwater table rises, one time the heavy showers process generally can not cause sloping body groundwater table significantly to rise, but when the rainfall in early stage accumulates, the slope ground saturation ratio is high and higher groundwater table arranged, with this understanding, the groundwater table of the further lifting of heavy showers process slope body will cause that slope failure produces the landslide.If drainage measure can in time be discharged underground water in sloping body groundwater table uphill process, just can effectively prevent the landslide, reduce the generation of geological disaster.
The arterial drainage measure of current side slope has: underdrainage hole, horizontal drainage channel, collecting well draw water, surface drainage ditch and weeper drain etc., the subject matter that these drainage measures exist has: (1) drainage measure is higher to the draining environmental requirement of sloping body, many side slopes often lack favourable geomorphologic conditions, cause the validity of drainage measure to be difficult to guarantee; (2) top drainage and superficial part draining are to improving the weak effect of slope stability; (3) underdrainage hole expense is higher, the construction technology complexity; (4) collecting well draws water needs power and regular administration.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of side slope inclined drill self-balancing siphon drainage method is provided.
The objective of the invention is to be achieved through the following technical solutions: a kind of side slope inclined drill self-balancing siphon drainage method, this method is: siphon drainage pipe enters the deep of side slope by the inclined hole that has a down dip, relative relief is less than 9m at the bottom of the aperture of maintenance inclined hole and the hole, from drawing siphon drainage pipe at the bottom of the hole of inclined hole to domatic certain position, make the water inlet of siphon drainage pipe identical with the delivery port elevation, when slope body water level rises, draining in real time.
The invention has the beneficial effects as follows: use side slope inclined drill self-balancing siphon drainage method of the present invention, can realize the draining of side slope deep, solve the draining governing problem of major landslip, the construction costs of guaranteeing to keep stability of slope is low, governance process does not relate to earthwork evacuation, and operation is simple to administer project implementing process, the good reliability of drainage measure, compliance is strong, and drainage procedure need not power and regular management maintenance.
Description of drawings
Fig. 1 is the implementation schematic diagram of side slope inclined drill self-balancing siphon drainage method of the present invention;
Among the figure: standpipe 5, control groundwater table 6 at the bottom of equalization of discharge pipe 1, gutter 2, inclined drill 3, potential slide plane 4, the hole.
The specific embodiment
Principle of the present invention is the deep that siphon drainage pipe is entered side slope by the inclined hole that has a down dip, relative relief is less than 9m at the bottom of the aperture of maintenance inclined hole and the hole, from drawing siphon drainage pipe at the bottom of the hole of inclined hole to domatic certain position, make the water inlet of siphon drainage pipe identical with the delivery port elevation, when slope body water level rises, draining in real time.
The technical scheme that adopts of dealing with problems comprises the combination of two aspects: (1) utilizes downward-sloping boring to enter sloping body deep, guarantee aperture and hole by the inclination angle of regulating inclined drill at the bottom of relative relief less than 9m; (2) utilize the standpipe of gutter water inlet and delivery port to make up a kind of self-balancing siphonic system, groundwater table rising whenever sloping body, discharge sloping body underground water in real time by siphonage is long-term, realize dynamic all the time the water level of water level in the hole of sloping body near delivery port.
Side slope inclined drill self-balancing siphon drainage method of the present invention, concrete enforcement may further comprise the steps:
(1) investigation and analysis slope project geological conditions, grasp the stability features and the Rock-soil Mass Structure feature of side slope, understand supply, runoff and the discharge regime of slope underground water, the relation of analysis of slope stability and groundwater effect is confirmed the influence of WATER LEVEL CHANGES to Landslide Stability.Carry out the slope project geological prospecting, analyze the position of definite potential slide plane 4 that may come down.
(2) carry out the layout design of inclined drill 3.According to the scale on potential landslide, arrange 1 ~ 3 row's inclined drill self-balancing siphon drainage pipe along the side slope vertical section, the spacing of wells can be determined according to concrete hydrogeological conditions on the cross section, about the general desirable 10m of the cross section spacing of wells.In the drilling process, the actual sloping body geologic structure that discloses of foundation is suitably adjusted the degree of depth of boring, making boring enter potential slide plane below 4 as far as possible.
(3), determine the position of standpipe 5 at the bottom of the installing hole according to the position of potential slide plane 4.Generally speaking, should make that the mouth of pipe of standpipe 5 is lower than potential slide plane at the bottom of the hole.The mouth of pipe elevation of standpipe 5, the delivery port elevation of definite equalization of discharge pipe 1 in view of the above at the bottom of the mensuration hole.Connect equalization of discharge pipes 1 with gutter 2, and the other end of gutter 2 is inserted at the bottom of the hole of inclined drill 3 in the standpipe 5.
(4) realize initial siphonic process.Equalization of discharge pipe 1 external vacuum pump, bleeding makes gutter 2 be in temporary vacuum, realizes initial siphonic process.When groundwater table is higher, also can in boring, water filling realize initial siphonic process.
(5) slope underground water position control procedure.When the groundwater table of inclined drill 3 is higher than the delivery port of equalization of discharge pipe 1, siphonic process takes place, utilize siphonage to discharge the underground water of boring 3, realize the groundwater table decreasing of inclined drill 3, groundwater table up to boring 3 is identical with the delivery port water level of equalization of discharge pipe 1, reach the control groundwater table 6 of goal-setting, siphonic process temporarily stops.All keep fixed level in the pipe of standpipe 5 at the bottom of equalization of discharge pipe 1 and the hole at this moment.After rainfall was next time risen sloping body groundwater table, the groundwater table of inclined drill 3 can be higher than the delivery port water level of equalization of discharge pipe 1 again, and siphonic process repeats once more, makes sloping body be in lower groundwater table state all the time.
