Abstract
The utility model relates to a seepage-proofing facility for an underground project and particularly relates to an outer blind ditch for waterproof facilities of an underground project. The outer blind ditch is suitable for an underground project structure which has a high water level when being arranged at the outer part of a basement and is located in a moist and humid environment for a long time. The outer blind ditch comprises a horizontal cushion layer, wherein an outer wall, a macadam water-permeable layer, a brick wall and a coarse sand water-filtering layer are respectively above the cushion layer; a water collection pit is arranged under the cushion layer, and a water pump is arranged in the water collection pit and is connected with one end of a drain pipe. According to the outer blind ditch, the blind ditch can be arranged on the outer side of a base plate of the underground project to lower the water level of the outer side of the underground project so as to reduce the water pressure on a concrete structure, and the water can be drained through the drain pipeline by virtue of the terrain trend. Furthermore, the water can be drained into a municipal drainage pipe net by utilizing a draining pump through cooperation of the blind ditch with a water-collecting well.
Description
Technical field
The utility model relates to a kind of facility for the underground construction antiseepage, relates in particular to a kind of outer french drain for the underground project waterproof facility, is applicable to the basement external water level high, is in for a long time the underground engineering structure in moistening, wet environment.
Background technology
The traditional handicraft way: after basement agent structure completion, after concrete structure reached design strength and requires, waterproofing course was done at outside shear wall position, then does topping, finally carried out the earthwork or layering even compacting in sand side's is backfilled to the ground design absolute altitude.This traditional handicraft is processed; higher if be in for a long time groundwater table; or in moist and moist environment; the underground water of surrounding can produce huge horizontal pressure force to underground engineering shear wall; waterproofing course and topping are very easily damaged, and concrete structure is in for a long time the decorative cover to underground chamber interior in moist and moist environment and easily causes damage.If in construction, the basement shear wall structural concrete is built uncompacted position, the structure porosity is large, easily cause inner corrosion of steel bar and seepy question, will affect the safety of underground engineering structure and use function, therefore later period maintenance and cost of upkeep will be very high, will produce quality accidents for a long time in the past.
Summary of the invention
In order to overcome above-mentioned defect, the utility model purpose is to provide a kind of technique simple and convenient, a kind of outer french drain for the underground project waterproof facility of good seepage-proof property.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of outer french drain for the underground project waterproof facility, it comprises the bed course of level, above bed course, is respectively arranged with exterior wall, rubble pervious layer, brick wall, coarse sand drainage layer, is arranged with sump at described bed course, in sump, be provided with water pump, water pump connects an end of gutter.
The other end of described gutter is connected to the municipal drainage pipe network.
On described coarse sand drainage layer, be coated with geotextiles.
The beneficial effects of the utility model:
It is high that the utility model is applicable to the basement external water level, is in for a long time the underground engineering structure in moistening, wet environment;
The utility model, in order to reduce the water level in the underground construction outside, to reduce the water pressure to concrete structure, can be established french drain in the outside of underground construction base plate, and utilize the trend of physical features and drainage pipe that water is discharged.Also can adopt the method for french drain in conjunction with collecting well, utilize drainage pump that water is expelled in the municipal drainage pipe network.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be elaborated:
A kind of outer french drain for the underground project waterproof facility, it comprises the bed course 1 of level, above bed course 1, be respectively arranged with exterior wall 2, rubble pervious layer 3, brick wall 4, coarse sand drainage layer 5, it is characterized in that: be arranged with sump 6 at described bed course 1, in sump 6, be provided with water pump 7, water pump 7 connects an end of gutter 8.
The other end of described gutter 8 is connected to the municipal drainage pipe network.
On described coarse sand drainage layer 5, be coated with geotextiles 9.
The utility model, in order to reduce the water level in the underground construction outside, to reduce the water pressure to concrete structure, can be established french drain in the outside of underground construction base plate, and utilize the trend of physical features and drainage pipe that water is discharged.Also can adopt the method for french drain in conjunction with collecting well, utilize drainage pump that water is expelled in the municipal drainage pipe network.
