Abstract
The utility model relates to a kind of high water level dewatering construction structures, it include the excavation top curve for position restriction, the basialveolar line limited is excavated for foundation trench inside top curve with being located to excavate, basialveolar line institute's rail portion is that foundation trench excavates position, it was equally spaced in gap between excavation top curve and the basialveolar line around basialveolar line one week and is provided with pipe well, and the pipe well by protrude into the suction channel in pipe well summarize be connected to suction total pipeline on, suction pump is provided on suction total pipeline, the foundation trench excavates the observation well being provided on position for groundwater depth observation, light well point is additionally provided between the basialveolar line and pipe well, the light well point is placed equidistant with one week around basialveolar line.
Description
Technical field
The utility model relates to high water level construction area precipitation processing technology field, in particular to a kind of Yellow River basin high water level
Construction area light well point precipitation technology in conjunction with pipe well.
Background technique
As urban ecology water system builds lasting promotion, water delivery pump station engineering gradually increases.In water delivery pumping plant engineering construction
In, since pumping plant generally build river side in, how precipitation just becomes the keys of construction of pumping station success or failure.General Dewatering uses
Tube well dewatering, since pumping plant basis is deeper, in Yellow River basin high water level construction area, after these single dewatering measure constructions easily
There is side slope occluded water infiltration phenomenon, causes the partial collapse of excavation slope.Since pumping plant foundation excavation is deeper, excavation slope
Partial collapse is easy to induce safety accident.Since Yellow River basin is sandy silt layer or fine sand layer, bottom, which is formed, is detained water layer,
The easy to carry fine particle of occluded water seepage flow into foundation pit, often results in the partial collapse of excavation slope.
Summary of the invention
The technical solution of the utility model is: a kind of high water level dewatering construction structure includes opening for position restriction
Top curve is dug, and positioned at the basialveolar line for excavating limit for foundation trench excavated inside top curve, the enclosing portion, basialveolar line institute
It is divided into foundation trench and excavates position, around the setting that is equally spaced in basialveolar line one week in the gap between excavation top curve and the basialveolar line
There is a pipe well, and the pipe well summarizes by protruding into the suction channel in pipe well and is connected on suction total pipeline, aspirates total pipeline
On be provided with suction pump, the foundation trench excavates the observation well being provided on position for groundwater depth observation, the base
Light well point is additionally provided between the line of rabbet joint and pipe well.
The light well point is placed equidistant with one week around basialveolar line.
Beneficial effect caused by the utility model is: since Yellow River basin is sandy silt layer or fine sand layer, bottom
It is formed and is detained water layer, single tube well dewatering, the easy to carry fine particle of occluded water seepage flow into foundation pit often results in foundation pit side
The partial collapse on slope, light well point and tube well dewatering combined structure efficiently solve occluded water exudation problem；Pipe well with it is light-duty
The combination precipitation of well point substantially increases dewatering effect, first use tube well dewatering, quick lowering of watertable, by observe well,
Earth excavation is carried out in time, and occluded water in soil layer is discharged in well-points dewatering, solves occluded water Seepage problems, both pit slot water level, meets
Execution conditions, while guaranteeing side slope safety.
Detailed description of the invention
Fig. 1 is the structure structure chart of the utility model.
In figure: 1, excavating top curve 2, basialveolar line 3, pipe well 4, observation well 5, light well point.
Specific embodiment
The technical solution of the utility model is described further combined with specific embodiments below.
Embodiment 1
A kind of high water level dewatering construction structure as shown in Figure 1: includes for the excavation top curve 1 of position restriction and position
In excavating the basialveolar line 2 for excavating limit for foundation trench inside top curve 1, described 2 rail portions of basialveolar line are opened for foundation trench
Position is dug, was equally spaced in the gap between excavation top curve 1 and the basialveolar line 2 around basialveolar line one week and is provided with pipe well 3,
And the pipe well 3 by protrude into the suction channel in pipe well summarize be connected to suction total pipeline on, aspirate total pipeline on be arranged
There is suction pump, the foundation trench excavates the observation well 4 being provided on position for groundwater depth observation, the basialveolar line 2
Light well point 5 is additionally provided between pipe well 3.
The light well point 5 is placed equidistant with one week around basialveolar line 2.
The utility model is when in use: firstly, first use tube well dewatering, quick lowering of watertable, and by observing well, and
Shi Jinhang earth excavation；Water level is close to pit slot basis, and then, Application of light well point precipitation can vacuum cavitations be deep in drainage foundation trench rapidly
Spend or more water-bearing layer underground water, and reduce underground flood peak, and can relatively efficiently solve occluded water Seepage problems, prevent from being detained
Water carries fine particle seepage flow into foundation pit, to cause the partial collapse of excavation slope.
Claims (2)
