Utility model content
For overcoming the defect existing for prior art, now providing a kind of dewatering well to shunt in a well structure, to solve the problems such as such as concrete is excessive existing for existing flange shut-in well, and improving quality and the efficiency of the construction of dewatering well shut-in well further.
For achieving the above object, a kind of dewatering well shut-in well structure is provided, comprise pre-buried base plate, pre-buried base plate is arranged at the pithead position of dewatering well and has the through hole with well head conducting, pre-buried base plate is installed with the first tube sealing, first tube sealing and through hole conducting, on the first tube sealing, conducting connects one second tube sealing, the top closure of the second tube sealing.
The beneficial effect of the utility model dewatering well shut-in well structure is,
1) tube sealing of syllogic can realize flexible and efficient dismounting in the well head of dewatering well;
2) under the condition of identical shut-in well effect (stopping concrete excessive), mode more save trouble and labor, the saving cost that the utility model is shunt in a well than existing flange, the mode of existing flange shut-in well then needs higher construction cost.
Preferably, on the first tube sealing, conducting connects a tube connector, and the second tube sealing conducting is connected on tube connector.
Preferably, the internal diameter of tube connector is greater than the external diameter of the first tube sealing and the second tube sealing, and the inwall of tube connector has thread segment, the outer wall of the first tube sealing and the second tube sealing has thread segment, and then tube connector is screwed together in outside the first tube sealing, and the second tube sealing is screwed together in tube connector.
Preferably, the top closure of the second tube sealing is provided with a cover plate.
Preferably, the first tube sealing and the second tube sealing are hot-galvanized steel pipe, and the first tube sealing is welded to connect on pre-buried base plate, and bridge welding is connected to the top of the second tube sealing in succession.
Preferably, pre-buried base plate has built layer of concrete, the first tube sealing stretches out layer of concrete.

Detailed description of the invention
For the benefit of to the understanding of structure of the present utility model, be described below in conjunction with drawings and Examples.
With reference to Fig. 1, it is the overall structure schematic diagram for the utility model dewatering well shut-in well structure.With reference to Fig. 2, for corresponding to the decomposing state schematic diagram of Fig. 1.
Shown in composition graphs 1 and Fig. 2, the utility model provides a kind of dewatering well shut-in well structure, comprise one piece of pre-buried base plate 1, this pre-buried base plate 1 is arranged at the pithead position of dewatering well and has the through hole 10 with well head conducting, pre-buried base plate 1 is installed with the first tube sealing 2, first tube sealing 2 and through hole 10 conducting, on the first tube sealing 2, conducting connects a tube connector 4, second tube sealing 3 conducting is connected on tube connector 4, the top closure of the second tube sealing 3.Pre-buried base plate 1 has built layer of concrete, and the first tube sealing 2 stretches out layer of concrete.
Particularly, the internal diameter of tube connector 4 is greater than the external diameter of the first tube sealing 2 and the second tube sealing 3, and the inwall of tube connector 4 has thread segment, the outer wall of the first tube sealing 2 and the second tube sealing 3 has thread segment, and then tube connector 4 is screwed together in outside the first tube sealing 2, and the second tube sealing 3 is screwed together in tube connector 4.
Comparatively preferably, the top closure of the second tube sealing 3 is welded with a steel deck-plate 30.First tube sealing 2 and the second tube sealing 3 are galvanizing round steel pipe, and the first tube sealing 2 is welded to connect on pre-buried base plate 1.
After having said structure feature, shown in composition graphs 1 to Fig. 6, the utility model can by following implementation Process:
A. as Fig. 1, select general steel plate as pre-buried base plate 1, and a through hole 10 identical with the first tube sealing 2 external diameter is offered in the center of this pre-buried base plate 1, first tube sealing 2 be welded to connect in this through hole 10 place and then be fixed on pre-buried base plate 1, again this pre-buried base plate 1 is welded in the pithead position of dewatering well, with this, the first tube sealing 2 directly and well head conducting;
B. as Fig. 2, tube connector 4 is screwed togather the top outer wall being anchored on the first tube sealing 2;
C. with reference to Fig. 3, for first of the utility model dewatering well shut-in well structure implements view, as shown in Figure 3, the pump hose 5 of powerful for 3KW self priming pump is inserted the first tube sealing 2 until this pump hose 5 is deeply to underground water level, afterwards, about half an hour of drawing water.Enforcement like this, mainly in order to protect weld seam, guarantees that weld seam can naturally cool thus reach environment temperature smoothly, avoids tube sealing meet cold because directly meeting water and then cause commissure to produce embrittlement cracking;
D. with reference to Fig. 4, for second of corresponding diagram 3 implements view.As shown in Figure 4, pump hose 5 is extracted out in the first tube sealing 2.
E. with reference to Fig. 5, for the 3rd of corresponding diagram 4 implements view.As shown in Figure 5, the second tube sealing 3 is screwed togather and is tightened against on tube connector 4, by steel deck-plate 30 water level lowering well sealing on the second tube sealing 3 top;
F. with reference to Fig. 6, for the 4th of corresponding diagram 5 implements view.As shown in Figure 6, smear leak stopping spirit in each commissure, and on pre-buried base plate 1, build formation layer of concrete 6, to realize pre-buried object, and then complete construction.
After completing above-mentioned implementation process, following characteristics of the present utility model should be able to be embodied:
1) tube sealing of syllogic can realize flexible and efficient dismounting in the well head of dewatering well;
2) under the condition of identical shut-in well effect (stopping concrete excessive), mode more save trouble and labor, the saving cost that the utility model is shunt in a well than existing flange, the mode of existing flange shut-in well then needs higher construction cost.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thus, some details in embodiment should not formed restriction of the present utility model, the utility model by the scope that defines using appended claims as protection domain.
