Abstract
The present invention belongs to foundation stratum technology, in particular it is an avalanche prevention and leakage blocking process for cutoff wall construction. Said process can be closely combined with construction of cutoff wall, its hole interior adopts large-diameter wall-protecting pipe to make wall protection, so that it possesses the advantages of quick construction, high-efficiency, short construction period and low construction cost, etc.
Description
The invention belongs to foundation treatment technology, be specifically related to a kind of impervious wall construction and soilslip-resisting and leakage-blocking process.
At present, at some reservoirs of China more serious seepage phenomenon is arranged, there is certain unsafe factor, especially in flood season, dangerous situation is bigger, therefore these reservoirs suddenly must be built impervious wall, we know that the reservoir dam ground seldom is single soil property, often by clay, sandy loam, husky, gravel, compositions such as cobble, that have even for no sand-pebble, the basement rock shallow-layer also has solution cavity, the crack, therefore can cause mud to run off in a large number, so that its liquid level is difficult to remain on predetermined height, thereby may cause that dam body caves in, the measure of taking when running into serious thief zone in the impervious wall construction process mainly contains two kinds of measures: (one) dwindles the groove segment length in conjunction with impervious wall construction, first making hole construction main aperture and leak stopping before the grooving, bore again to split and pay the hole grooving, reduce the whole groove section risk of caving in, improve concentration of hydraulic mixture in the groove during leak stopping, wash in a pan slurry when creeping into less and add in the hole, to load when clay is met serious spillage various materials etc. and in time mend slurry, though the method is convenient and easy, to the often thoroughly leak stopping of severe leakage layer, very easily cause spillage repeatedly, thus cause collapse the hole or on a large scale dam body cave in.(2) prospecting finds out that serious thief zone implements grouting treatment then before the impervious wall construction, and this kind method is not only invested greatly, and the long in time limit and restriction that is subjected to equipment is to strong seepage floor DeGrain, accident-proneness.
The object of the present invention is to provide a kind of not only quick, efficient, easy to operate but also the serious spillage stratum that runs in the impervious wall construction, strong percolation zone and solution cavity grown the tangible anti-collapse leak stopping new technology of stratum treatment effect.
The object of the present invention is achieved like this: impervious wall construction and soilslip-resisting and leakage-blocking process comprises the following steps:
A, pore-forming utilize the pore-creating of impervious wall construction machinery, and hole depth is to more than the lost-circulation zone, and aperture and impervious wall thickness are equal to;
Impervious wall construction order Drilling main aperture is pressed in b, cloth hole, splits the arrangement in secondary hole;
C, following pipe only are lowered to heavy caliber retaining wall pipe in the impervious wall main aperture, simultaneously that heavy caliber retaining wall pipe is suitable for reading temporary fixed, manage outer slit clay refilling;
Creep in d, the pipe, utilize the drilling tool that matches with heavy caliber retaining wall pipe to continue to creep into to the leakage stratum;
E, hole flushing, after being drilled into the leakage stratum, mud runs off rapidly in the pipe, continues slip casting or water filling in pipe, and boring mud is washed away, and makes leakage passage unimpeded;
F, fill out filling,, select one or more to fill out the filling material, till material feeding no longer according to the leakage degree;
G, whole hole, after filler reaches time of setting, in pipe during slip casting not spillage get final product;
H, tube drawing are extracted heavy caliber retaining wall pipe with the hydraulic pipe drawing machine.
Hole depth apart from the leakage stratum more than 2 meters.Heavy caliber retaining wall pipe is the nodular compound tube, and caliber is 273-800mm.
In filling out the filling step, serious thief zone, strong percolation zone, especially severe leakage stratum are filled out filling and can be taked following measures: (1) is pumping mud or water while back-up sand in managing in pipe, stops when water level rises in waiting to manage; (2) in pipe, fill out one or more prebagged materials; (3) impact in pipe with special drilling tool, prebagged material is stopped up leakage passage to extruding all around, filler impacts once more once more, and 2-3 time repeatedly, until no longer material feeding.
In filling out the filling step, can directly in pipe, fill out packed pea gravel concreten to connecting solution cavity, then in pipe, impact with special drilling tool, 2-3 time repeatedly, no longer till the material feeding.
Serious thief zone, strong percolation zone institute underfill material can be flocculation, quick-setting mortar, and the major ingredient component and the ratio of weight and number of described mortar are:
Water 0.7-0.8 cement 1 sand 1.5-3.0
It is auxilliary more in addition that to join by mass of cement percentage be the flocculant of 2-3% and the accelerating admixture of 1.5-4%.
The perforation solution cavity is filled out the filling material be flocculation, rapid hardening pea gravel concreten, the component of described pea gravel concreten and ratio of weight and number are:
Water 256-267 cement 366 sands 659
Stone 805 flocculants 11 accelerating admixture 8-11
The filling material is filled out on especially severe leakage stratum be flocculation soft aggregate expansive concrete, the component and the ratio of weight and number of described soft aggregate expansive concrete major ingredient are:
Water 0.65 cement 1 sand 1 soya bean 0.5-1.5
The auxilliary more in addition flocculant of by mass of cement 2-3% and the accelerating admixture of 1-3% of joining.
This technology impervious wall construction of combining closely, utilize the impervious wall construction mechanical hole building, speed of fulfiling hole is fast, and hole depth is to missing more than the stratum, spillage in having avoided creeping into, adopt the heavy caliber retaining wall to manage and protect wall in the hole and make when spillage occurring in the drilling process, be difficult for caving in, under the situation of not replenishing mud, can in pipe, take leaking-stopping measure.Simultaneously can choose the different filling materials of filling out according to different leakage degree, and realize quick filler, so this technology have quick construction, efficient, the duration is short, easy to operate, fill out advantages such as the optional scope of filling material is wide, construction cost is low, and it is serious more to have seepage, the tangible more characteristics of its superiority can solve effectively that conventional art can not solve or masty problem.This technology also is adapted to the processing of serious thief zone in the Other Engineering project.
Describe in detail below in conjunction with embodiment.
A kind of impervious wall construction and soilslip-resisting and leakage-blocking process, this technology can be undertaken by the processing step in the technique scheme, wherein the aperture is 800mm, the leakage depth of stratum is 56-58m, hole depth is to missing 2 meters more than the stratum, and heavy caliber retaining wall pipe is the nodular compound tube, and caliber is 550mm, if being serious thief zone or strong percolation zone, lost-circulation zone fills out the optional mortar of stating proportioning that takes off of filling the material, (kg/m of unit
