Abstract
The utility model relates to a closed well cover for an underground water pump house using at floodway districts, flood detention districts and shoaly districts. The utility model comprises a well cover body which is provided with a central through hole, a well cover tube which is arranged in the central through hole, a well cover seat which is matched with the well cover body is arranged below the well cover body, and the inner diameter of the well cover seat is larger than the external diameter of a well pipe with is matched with the well cover seat; an outward extended waterstop ring is arranged at the external edge point of the lower port of the well cover seat. Because the utility model adopts the structure characteristics, the phenomenon that cracks appear on a base at a pumping well mouth, which is caused by the sinking of the well pipe, can be avoided, and the normal operation of the underground water pump house can be ensured.
Description
The utility model relates to a kind of pump chamber sealed well lid, relates to a kind of sealed well lid that is applicable to capable detention basin, beach district underground water pump chamber specifically.
At present, (river) beach district, seabeach district or low-lying shoaly land district construction have many underground pump chambers in the great river, its objective is for the motor-pumped well groundwater abstraction by setting within it.Because underground pump chamber is positioned at the beach district, for preventing when groundwater table raises, underground water slave well head in the well pipe overflows and floods pump chamber, cause the damage of indoor electric appliance equipment and stop water supply, knownly put the model measure above the basis at motor-pumped well mouth place for a well lid body that has a central through hole is installed, and place the interior well lid pipe of this central through hole, and the well lid body directly is connected with the well pipe by flange, and the well head pipe box is loaded within the well pipe.Can play the underground water effect that the slave well head overflows in the well pipe when groundwater table raises though adopt the model measure of putting of this structure, but after date when motor-pumped well moves a section, or enter rainy season, or enter flood season, the well pipe will sink owing to the effect of gravity, cause the basis at motor-pumped well mouth place the crack to occur and cause underground water to overflow from the crack entering underground pump chamber.
The purpose of this utility model provides a kind of sealed well lid that is applicable to capable detention basin, beach district underground water pump chamber with regard to being to overcome above-mentioned existing in prior technology deficiency.
The purpose of this utility model can realize by following measure:
The utility model comprises the well lid body that has central through hole, and places the well lid pipe in this central through hole, is provided with a manhole cover base that is complementary with it below the well lid body; Described manhole cover base internal diameter is greater than the well external diameter of pipe that matches with it; Be provided with outward extending seal ring at this place, manhole cover base lower port outer.
Be central through hole on the further raising well lid body and the sealing effectiveness between the well lid pipe, described well lid body and well lid Guan Weiyi overall structure; Described well lid body and manhole cover base lump together by the connector sealed junction.On described well lid body, offer three through holes around central through hole is uniform, this through hole longitudinal section be shaped as T shape, its objective is power cable and fluviograph cable, and the stack of adjusting wellhole internal gas pressure is drawn outside the motor-pumped well for the ease of being positioned at the motor-pumped well inner pump.
Advantage of the present utility model just is to adopt and is provided with a manhole cover base that is complementary with it below the well lid body, described manhole cover base internal diameter is greater than the well external diameter of pipe that matches with it, and be provided with outward extending seal ring at place, this manhole cover base lower port outer, thereby avoided causing the basis at motor-pumped well mouth place the generation of crack phenomenon to occur, guaranteed the normal operation of underground pump chamber because of the sinking of well pipe.
The drawing of accompanying drawing is described as follows:
Fig. 1 cuts open figure for master of the present utility model.
The utility model is done one below in conjunction with specific embodiment (accompanying drawing) and is described in detail:
As shown in the figure, the utility model comprises the well lid body 1 that has central through hole, and places the well lid pipe 2 in this central through hole, and described well lid body 1 is an overall structure with well lid pipe 2; On well lid body 1, offer three through holes 6 around central through hole is uniform, this through hole longitudinal section be shaped as T shape; Be provided with a manhole cover base that is complementary with it 3 below well lid body 1, well lid body 1 lumps together by the connector sealed junction with manhole cover base 3; Described manhole cover base 3 internal diameters are greater than well pipe 4 external diameters that match with it; Be provided with outward extending seal ring 5 at this place, manhole cover base 3 lower port outers.
