Description
Technical Field
The utility model relates to an on-the-spot foundation ditch construction field specifically is an inside collection drainage system of foundation ditch.
Background
In the construction process of construction engineering, all buildings and structures need to be subjected to foundation pit excavation operation construction, most foundation pits are subjected to precipitation firstly and then subjected to foundation pit excavation work, but during foundation pit excavation construction in coastal areas, due to the complexity of underground water systems, a large amount of underground water still flows into the foundation pits, and great trouble is brought to construction; during field construction, people usually weld a box with an upper opening on a steel plate and bury the box in a foundation pit for water collection and pumping operation, and the steel plate box has the defects of water impermeability, easy floating, potential safety hazard and increased cost due to the fact that the box is completely welded by the steel plate; in order to save cost, people usually directly excavate a sump pit in the foundation pit, and then carry out precipitation construction, and its shortcoming is that the sump pit is unstable, takes place to collapse easily, and the inside silt of foundation pit blocks up the water pump easily.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide a collection drainage device convenient to use and effectual difficult jam catchments.
In order to achieve the above object, the present invention is realized as follows:
a water collecting and draining system in a foundation pit comprises a water permeable water collecting well, a water pump and a water pipe; the water-permeable water collecting well is of a box-shaped structure, the peripheral side wall and the bottom of the water-permeable water collecting well are provided with water-permeable holes, and meanwhile, the top edge of the water-permeable water collecting well is provided with a lifting lug; the water pump is placed in the water-permeable water collecting well, the specification and model of the water pump are selected according to actual construction requirements, and a water outlet of the water pump is fixedly connected with a water pipe and used for draining accumulated water in the water-permeable water collecting well; the water pipe is a strip-shaped hollow drainage structure, is fixedly connected with the water pump drainage port and can drain water transmitted by the water pump to the outside of the foundation pit.
The water collecting and draining system in the foundation pit is characterized in that a water permeable water collecting well of a box-shaped structure comprises a bottom plate and a side wall, and the water permeable water collecting well is a whole formed by simultaneously pouring concrete; the thickness is 50mm-100 mm;
the inside collection drainage system of foundation ditch, the lateral wall consolidation of the water-collecting well that permeates water of lug is connected, the lug is preferred to select the reinforcing bar clout preparation for use.
This inside collection drainage system of foundation ditch can gather the inside ponding of foundation ditch fast through the inside collection drainage system of foundation ditch, keeps integrality, the stability of ponding structure, stops to lead to catchment structure to produce the come-up to move, the position phenomenon because of water pressure, can effectively completely cut off debris such as outside silt simultaneously, and collection, drainage operation construction are accomplished to swift efficient, guarantee that the foundation ditch is inside not to have ponding.
Drawings
Fig. 1 is a schematic structural diagram I of the water collecting well.
Fig. 2 is a schematic structural diagram II of the water collecting well.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1 and 2, a water collecting and draining system in a foundation pit is composed of a water permeable water collecting well 1, a water pump 2 and a water pipe 3; the water-permeable water collecting pit 1 consists of a water-permeable bottom plate 11, a water-permeable side wall 12 and a lifting lug 13.
The water-permeable water collecting well 1 is a key part of a water collecting and draining system in a foundation pit, is of a box body structure with an upper opening and formed by enclosing a water-permeable bottom plate 11 and a water-permeable side wall 12 together, and particularly the water-permeable bottom plate 11 and the water-permeable side wall 12 are integrally formed by simultaneously pouring concrete.
The water-permeable bottom plate 11 is a bottom structure of the water-permeable water collecting well 1, four corners are fixedly connected with the four water-permeable side walls 12 to form a box structure with an unclosed upper part, and the special water-permeable bottom plate 11 is water-permeable concrete made of excess materials during concrete pouring, and the thickness of the water-permeable bottom plate is 50mm-100 mm.
The side wall 12 that permeates water is the side structure of the sump pit 1 that permeates water, and the lateral wall 12 that permeates water is connected with the bottom plate 11 that permeates water in a concretion manner, and four lateral walls 12 that permeate water enclose with the bottom plate 11 that permeates water and become a box body structure that upper portion is not closed, and the lateral wall 12 that permeates water of especial is the pervious concrete that is made by the clout when concrete placement, and thickness is 50mm-100 mm.
