For open water, a water pit is dug, a brick bed is built, and the open water is collected in the pit and pumped by a water pump. This approach has the following disadvantages: 1. the method is limited by soil types, when the soil is a sand layer, the soil layer is easy to flow, the building difficulty of the brick moulding bed is higher, and the brick moulding bed is easy to collapse due to the pressure of the side wall after being built; 2. the water pump directly contacts the pit bottom, the silt content in the discharged water is large, the load on the machine is large, the service life is shortened, silt is deposited in the sedimentation tank, and the cleaning cost is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple and easy sump pit for drainage precipitation of being convenient for among sand layer drops, drops into once, application scope is wide, preparation and operation are brief, recycle for solve the problem that the marginal soil layer of precipitation well collapses, reduce unnecessary clearance foundation ditch work, improve the precipitation effect, improve drainage efficiency.

The technical scheme of the utility model is that: the simple water collecting well used in a sandy soil layer and convenient for pumping drainage and precipitation comprises a square steel reinforcement cage 1, wherein a galvanized steel wire mesh 2 is surrounded on the outer side of the square steel reinforcement cage 1, and the galvanized steel wire mesh 2 is bound on the square steel reinforcement cage 1 through binding wires; a layer of filter screen 3 is wrapped outside the galvanized steel wire mesh 2, and the filter screen 3 is bound on the square reinforcement cage 1 through binding wires; and two steel bar hanging rings 4 are welded at the opening of the square steel bar cage 1.

Further, 1 size of square steel reinforcement cage is 800mm x 2000mm, and the reinforcing bar diameter is 18mm, and horizontal reinforcing bar interval is 400mm, and vertical reinforcing bar interval is 400mm, and bottom reinforcing bar interval is 400mm, adopts the welding mode to connect between the reinforcing bar.

Furthermore, the mesh size of the galvanized steel wire mesh 2 is 12mm multiplied by 12mm, the diameter of the steel wire is 0.7mm, and the galvanized steel wire mesh 2 is formed by binding a plurality of galvanized steel wire single meshes through binding wires.

Further, the filter screen 3 is a safety net.

Further, rings 4 are formed by bending steel bars with the diameter of 8 mm.

The utility model discloses following profitable effect has:

the utility model has the advantages that the frame support avoids the influence of the collapse of the side groove of the precipitation pit, reduces the manpower and material resources for cleaning the sediment at the bottom of the pit, blocks the sediment through the filter screen, reduces the sediment entering the sedimentation tank through the water pump, and avoids increasing the work for cleaning the sediment; the raw material of the steel bar for manufacturing the steel bar cage uses steel bar waste, thereby meeting the concept of energy conservation and environmental protection; local materials are used, and the used materials are from a construction site, so that the method is convenient and quick; the manufacturing is simple, and workers can get hands without professional training; the flexibility is stronger, can confirm size specification by oneself according to project actual need, does benefit to and uses widely.
