In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying positive importance.
The utility model will be further described with reference to the accompanying drawings.
In the existing underground structure construction, real-time monitoring of the underground water level condition is difficult, if the underground water level is too high, the underground structure floats upwards, and the safety and quality of the structure are affected. Although the dewatering wells are arranged in the earlier stage, most of the dewatering wells are closed after the construction of the underground bottom plate. The common practice is to reserve a plurality of dewatering wells which are not closed when the underground bottom plate is constructed so as to drain underground water. In the period of abundant groundwater, groundwater can flow out through the dewatering well, and water pumping from the dewatering well cannot be met. The water accumulation is formed in the basement due to the basement gushing, so that the subsequent construction is not facilitated, and the impermeability of the structure is also affected.
As shown in fig. 1, a simple dewatering device for preventing an underground structure from floating up comprises a dewatering pipe well 1 and a rubber hose 4, wherein a steel pipe 9 containing a water filtering hole is inserted in the dewatering pipe well 1, a sealing ring cover 3 is arranged at the upper port of the steel pipe 9 containing the water filtering hole, one end of the rubber hose 4 penetrates through the sealing ring cover 3 to the inside of the dewatering pipe well 1, and the end part of one end of the rubber hose 4 inserted into the dewatering pipe well 1 is 1 meter below a basement bottom plate 2. The other end of the rubber hose 4 is arranged in a water collecting well 5, and a submersible pump 6 is arranged in the water collecting well 5; the outer side of the steel pipe 9 containing the water filtering holes is provided with a sand filling layer 10, a clay filling layer 8 is arranged on the sand filling layer 10, a basement bottom plate 2 is arranged above the clay filling layer 8, and a water stopping steel sheet 11 is arranged in the basement bottom plate 2.
Specifically, a through hole is formed in the sealing ring cover 3, the rubber hose 4 penetrates through the through hole, and a sealing rubber ring is arranged at the joint of the rubber hose 4 and the sealing ring cover 3. Rubber hose 4 specification adoptsA 25mm hole is reserved in the center of the sealing ring cover 3 and is used for inserting the rubber hose 4; the insertion is tight, and the water leakage is avoided in the precipitation process.
Specifically, sealing washer lid 3 and contain drainage hole steel pipe 9 looks adaptation. The sealing ring cover 3 is made of steel plates, and a rubber sealing ring is arranged in the sealing ring cover 3 so as to ensure that the sealing purpose can be achieved.
Specifically, the output port of the submersible pump 6 is connected to the three-stage sedimentation tank 7 through a pipe. The submersible pump 6 pumps water into the three-stage sedimentation tank 7 for treatment and then is used for sprinkling water and dust fall. The other section of the rubber hose 4 is connected to the nearest water collection well 5, and the groundwater uses its own water pressure to drain water into the water collection well 5 through the rubber hose 4. The immersible pump 6 is placed to the sump pit 5 the inside, and immersible pump 6 sets up the warning water level in advance, and when sump pit 5 water level reached the warning water level, immersible pump 6 will open and draw water. The submersible pump 6 pumps water to the water collecting well 5, and the sedimentation tank enters the field for secondary use. Drainage and drainage pressure release can effectively prevent the ground warehouse from floating up, and through organized drainage, the basement can be ensured to be dry simultaneously, and the phenomenon that ground is water everywhere caused by overflow of underground water is prevented.
The above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
