As preferably, on the above-mentioned second shutoff unit relief pipeline and pipeline control valve door are set.
As preferably, expansive concrete has been watered at the top in the hole of above-mentioned precipitation well, and builds completion at twice.
Compared with prior art, one of beneficial effect of the utility model is:
In the technical scheme of the utility model,, can the submersible of carrying out be arranged in the precipitation well and need not pre-buried reinforcement feature in the precipitation well, shorten engineering time and curing time greatly through standardization shutoff modular design;
In addition, plugging effect is good, difficult situation such as leak, and when needs second use precipitation well, can simple realization.
Description of drawings
For clearer explanation present specification embodiment or technical scheme of the prior art; To do simple the introduction to the accompanying drawing of required use in the description of embodiment or prior art below; Obviously, the accompanying drawing in describing below only is the reference to some embodiment in the present specification, to those skilled in the art; Under the situation of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the precipitation well plugging device of the utility model;
Fig. 2 is the structural representation of the shutoff unit of the utility model.
Wherein, the pairing name of the Reference numeral in the accompanying drawing is called:
The 1-first shutoff unit, the 2-second shutoff unit, 3-expansive concrete, 4-helicla flute, 5-relief pipeline, 6-pipeline control valve door.
The specific embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the embodiment of the utility model is not limited thereto.
Fig. 1 shows the structural representation according to the precipitation well plugging device of an embodiment of the utility model.An embodiment with reference to precipitation well plugging device shown in Figure 1; Comprise the shutoff unit; Said shutoff unit is a standardization shutoff module; The shutoff unit of a standard is arranged on one with it in the hole of the corresponding precipitation well of standard, is arranged on a shutoff unit in the precipitation wellhole and is used for shutoff water after through tight contact of hole wall of expanding with a said precipitation well, is provided with a shutoff unit in the hole of a said precipitation well at least., when implementing,, force in its hole that is fixed on the precipitation well with prefabricated shutoff unit by using deadweight or by means of other external force then according to precipitation well plugging device embodiment illustrated in fig. 1 according to the prefabricated shutoff of respective standard unit; The shutoff unit expands owing to contacting with water; Thereby the formation water barrier reaches the purpose of shutoff, when the water yield surpasses the expection amount of calculation; Can water in the pipeline be carried out pump drainage (shown in Fig. 2) through relief pipeline 5, to reduce shutoff unit buoyancy pressure.Through the standardization shutoff modular design of above description, can in the precipitation well, wear the water operation, because of adopting modularized design, no matter be that engineering time or curing time all shorten greatly.
With reference to another embodiment of precipitation well plugging device shown in Figure 1, said shutoff unit is a sea-tangle sealing plug.
Fig. 2 shows the structural representation of the shutoff unit of an embodiment of the utility model.
With reference to an embodiment of precipitation well plugging device shown in Figure 2, said shutoff is provided with helicla flute 4 on the unit, is provided with the expansion sealing rod in the said helicla flute 4.Said shutoff unit also is provided with relief pipeline 5 and pipeline control valve door 6.The body of the shutoff unit in the present embodiment is a concrete precast block, pre-buried relief pipeline 5 when prefabricated section is built, and on concrete precast block, carve helicla flute 4, again the expansion sealing rod is put into helicla flute 4;
Another embodiment with reference to precipitation well plugging device shown in Figure 1; The shutoff unit that is provided with in the hole of a said precipitation well is two; Comprise the first shutoff unit 1 and the second shutoff unit 2 that connect successively from bottom to top; The said first shutoff unit 1 is a sea-tangle sealing plug, and helicla flute 4 and relief pipeline 5 are set on the said second shutoff unit 2, is provided with in the said helicla flute 4 in expansion sealing rod and the said relief pipeline 5 and leaves pipeline control valve door 6.In the present embodiment; At first sea-tangle is bundled into 30 centimeter length, the first shutoff unit 1 by the precipitation aperture; The first shutoff unit 1 is filled in the precipitation well, and utilized deadweight with the prefabricated second shutoff unit 2 immediately or rely on other external force to force the first shutoff unit 1 and the second shutoff unit 2 to sink to the precalculated position and fix.Its principle is to utilize sea-tangle sealing plug water-swellable principle, makes and forms a sealing water barrier between sealing plug and the hole wall.If still have low amounts of water to see through sea-tangle sealing plug, the water-swellable sealing rod rainwater that twine on 2 surfaces, the second shutoff unit expands and increases and can form the sealing water barrier with hole wall once more, thereby forms sealing defence line, second road.Estimate calculated value if the water yield surpasses, but opening conduits by-pass valve control 6 carries out the pump drainage pressure release through relief pipeline 5.Stable or the first shutoff unit 1 forms enough frictional force with the second shutoff unit 2 and hole wall when the water yield, when operating mode is stablized, closes pipeline by-pass valve control 6.
With reference to another embodiment of precipitation well plugging device shown in Figure 1, expansive concrete 3 has been watered at the top in the hole of said precipitation well.
Each embodiment adopts the mode of going forward one by one to describe in this manual, and what each embodiment stressed all is and the difference of other embodiment that identical similar part cross-references gets final product between each embodiment.
" embodiment " who is spoken of in this manual, " another embodiment ", " embodiment ", etc., refer to the concrete characteristic, structure or the characteristics that combine this embodiment to describe and be included among at least one embodiment that the application's generality describes.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in manual.Further, when describing a concrete characteristic, structure or characteristics in conjunction with arbitrary embodiment, what institute will advocate is that other embodiment of combination realize that this characteristic, structure or characteristics also drop in the scope of the utility model.
