Abstract
The utility model discloses a vibrate joint vacuum pumping system, its characterized in that pumping system includes a plurality of movable's vibration exciter and precipitation well point. The utility model has the advantages that, simple structure, with low costs, effect are showing, and negative pressure that the malleation that can utilize the vibration exciter to form combines vacuum precipitation well point to form produces bigger pressure differential, and the ability of improvement drainage can further reduce soil body moisture content 2%~5%.
Description
Technical field
The utility model relates to dewatering of foundation device, is specifically related to a kind of vibrating vacuum and draws water system.
Background technology
At present, pollution soil recovery project and foundation treatment engineering generally adopt heavy-tamping method and consolidation.
Handling subgrade by intensity tamping is freely fallen to ground with surging force and vibration from eminence by very heavy hammer, thus improve the intensity of foundation soil and reduce its compressibility. It is applicable to reinforce powder soil and cohesive soil, plain fill and the miscellaneous fill of soft gravelly soil, sand, low saturation.
Consolidation, by arranging water exhaust system, increases load (or the barometric point reduced in ground), it is to increase foundation soil additional stress on ground, along with soil body pore water is discharged, soil body effective stress increases, and reaches raising soil strength, eliminates the foundation treatment method of sedimentation. But for the soil layer that perviousness is poor, along with the consolidation gradually of the soil body, the water in soil is often more and more difficult is discharged further, causes construction period to extend, and expense improves.
Above-mentioned two various methodologies respectively have advantage, also have limitation. The ground of the saturated clayey soil such as the very soft sill clay not thick for soil layer, bearing capacity of foundation soil is less demanding, soil body undrained shear strength is less than 20kPa and powder soil, clay, heavy-tamping method limited efficiency, quick and economic advantage is difficult to play, and adopt the consolidation cycle longer, reinforce costly. How making full use of both advantages, that develops a kind of this type of ground applicable adds solid method, is technical barrier urgently to be resolved hurrily.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, it is provided that a kind of vibrating vacuum is drawn water system, this system of drawing water by vibrator is combinationally used with precipitation well point, to produce bigger pressure difference, it is to increase draining ability.
The utility model object realizes completing by following technical scheme:
A kind of vibrating vacuum is drawn water system, it is characterised in that described in the system of drawing water comprise vibrator and the precipitation well point of some packaged types.
Described precipitation well point be arranged in arrays in ground, be at least furnished with a described vibrator between described precipitation well point adjacent column.
Described precipitation well point comprises well pipe and coupled vacuum extractor.
The utility model has the advantages that, structure is simple, cost is low, effect is remarkable, it is possible to use the negative pressure that the malleation that vibrator is formed is formed in conjunction with vacuum drop well point, produces bigger pressure difference, it is to increase the ability of draining, can reduce soil moisture content 2%��5% further.
Accompanying drawing explanation
Fig. 1 be in the utility model vibrating vacuum draw water System planes arrange schematic diagram;
Fig. 2 is that in the utility model, vibrating vacuum is drawn water system diagrammatic cross-section.
Embodiment
Feature of the present utility model and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
It is respectively as Fig. 1-2, figure mark 1-4: precipitation well point 1, vibrator 2, well pipe 3, vacuum extractor 4.
Embodiment: as shown in Figure 1, 2, the present embodiment is specifically related to a kind of vibrating vacuum and draws water system, and this system of drawing water is made up of the precipitation well point 1 being arranged in foundation soil body and the vibrator 2 that rest on the ground; Wherein, precipitation well point 1 comprises the well pipe 3 implanted in the soil body and the vacuum extractor 4 being connected with well pipe 3; Vibrator 2 is a kind of vibration machinery (power 1-3KW that can produce certain vibratory magnitude, radius of influence 2-3m, influence depth 3-6m), and can transversely or longitudinally move around, by forced vibration so that in ground the soil body form super pore water pressure, in conjunction with the negative pressure that vacuum-dewatering is formed, by the gravity water in soil body hole, even weak binding water is discharged.
As shown in Figure 1, 2, within the scope of pending ground, each precipitation well point 1, in arranged in arrays, the ground vacant lot between each adjacent column arranges the vibrator 2 of a packaged type, and vibrator 2 carries out moving around using the vacant lot between adjacent column as track vibrating.
As shown in Figure 1, 2, in the present embodiment, the draw water method of work of system of vibrating vacuum comprises the steps:
(1) in each precipitation well point 1 of arranged in arrays within the scope of pending ground, implant in ground predetermined depth by well pipe 3, and the vacuum extractor 4 being located on ground by well pipe 3 is connected;
(2) vibrator 2 is arranged in vacant lot between each road precipitation well point 1 adjacent column respectively;
(3) utilize each precipitation well point 1 to carry out vacuum to draw water, along with the consolidation vacuum-dewatering efficiency of the soil body obviously reduces, now, starting vibrator 2 makes its vacant lot between precipitation well point 1 move around, and makes the soil body form super pore water pressure by being vibrated by foundation soil body, and in conjunction with the negative pressure that vacuum-dewatering is formed, to produce bigger pressure difference, improve draining ability, soil moisture content 2%-5% can be reduced further, effectively shorten construction period and reduce expense.
Claims (3)
1. a vibrating vacuum is drawn water system, it is characterised in that described in the system of drawing water comprise vibrator and the precipitation well point of some packaged types.
2. a kind of vibrating vacuum according to claim 1 is drawn water system, it is characterised in that described precipitation well point be arranged in arrays in ground, be at least furnished with a described vibrator between described precipitation well point adjacent column.
