Abstract
The utility model discloses a basement soleplate precipitation well mouth blocking sleeve which comprises a vertical steel pipe. A stabilizing ring is welded to the outer periphery of the bottom of the steep pipe. A water stopping ring is welded to the outer periphery of the upper portion of the steel pipe. A flange plate is welded to the outer periphery of the upper opening of the steel pipe. The flange plate is provided with a cover plate. A rubber gasket is disposed between the flange plate and the cover plate. The basement soleplate precipitation well mouth blocking sleeve has the advantages double insurances are used, and the common problems that a water pump cannot be taken out and blocking fails due to the fact that the water stopping rings are disposed in traditional blocking sleeves are solved.
Description
Technical field
The utility model relates to pipe well blocking technology, is specifically related to basement bottom board dewatering well well head shutoff sleeve pipe.
Background technology
In Yangtze River Delta Area, soil layer is in the majority with silt, the suitable tube well dewatering of using.
In the basement construction stage, for dewatering, it is by designing requirement, groundwater table to be down to below design elevation that precipitation requires, prevent base plate floating, before pipe well completes before not sealing to basement backfill, ater-casting after basement bottom board has been constructed, need continue to draw water, also need to retain a part of pipe well, thereby occur the problem of pipe well shutoff.
Traditional pipe well method for blocking is, stops after precipitation, first at the sub-position of the pipe well mouth of pipe, hangs a keg, prevents that concrete from entering in hole, mixes, in input pipe well pipe with shutoff spirit, rapid setting cement, leak stopping king etc. with concrete.This way rises soon because stopping after precipitation water level, and before hardening of cement, water level may rise, and extrudes concrete and oozes out, and causes concrete surface to form pore or crack, leaks and causes shutoff to lose efficacy.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of basement bottom board dewatering well well head shutoff sleeve pipe, improves pipe well plugging effect.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: basement bottom board dewatering well well head shutoff sleeve pipe, the steel pipe that comprises vertical setting, described steel pipe bottom excircle is welded with stabilizing ring, described steel pipe top excircle is welded with seal ring, described steel pipe excircle suitable for reading is welded with flange, and described flange is provided with cover plate, between described flange and cover plate, is provided with rubber washer.
Preferably, described casing inner diameter is 273mm, and thickness is 5mm, and length is 500mm.
Preferably, described flange external diameter is 373mm, and thickness is 10mm, and described seal ring width is 100mm, and thickness is 5mm,
Preferably, described stabilizing ring width is 30mm, and thickness is 5mm, and described cover plate diameter is 473mm, and thickness is 5mm.
Preferably, between described cover plate and flange, be bolted, be evenly equipped with 10 bolts hole on flange, the diameter of described bolt is 10mm, and length is 60mm.
The steel sleeve structure that the utility model adopts is different from traditional structure, and it has adopted dual fail-safe measure, and what overcome traditional shutoff establishes seal ring in sleeve pipe, and water pump be cannot take out and the common fault of shutoff inefficacy.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is deep-well plan view;
Fig. 2 is 1-1 sectional view in Fig. 1;
Fig. 3 is for installing the sleeve structure schematic diagram of cover plate;
Fig. 4 is sleeve pipe scheme of installation;
Fig. 5 is well head reinforcing rib structure schematic diagram.
The specific embodiment
Below in conjunction with Fig. 1 to Fig. 3, the concrete structure of basement bottom board dewatering well well head shutoff sleeve pipe is explained, it comprises the steel pipe 1 of vertical setting, described steel pipe bottom excircle is welded with stabilizing ring 10, described steel pipe top excircle is welded with seal ring 11, described steel pipe excircle suitable for reading is welded with flange 12, described flange is provided with cover plate 13, between described flange and cover plate, is provided with rubber washer.When groundwater table is higher, with shutting water route with the cover plate of rubber pad packing ring, in dry place, build underplate concrete like this, construction quality can be guaranteed, the maximum of hydraulic pressure can be controlled in 5kg/cm2, in the concrete slow hardening stage, guarantee that underground water can not penetrate concrete, can not form crackle or hole.Sleeve pipe size is determined by well head inner corrugated pipe size, insertion depth, optionally can adopt the flanged (FLGD) common steel tube of welded steel pipe or finished product to make.Specific to the present embodiment, described casing inner diameter is 273mm, and thickness is 5mm, and length is 500mm.Described flange external diameter is 373mm, and thickness is 10mm, and described seal ring width is 100mm, and thickness is 5mm.Described stabilizing ring width is 30mm, and thickness is 5mm, and described cover plate diameter is 473mm, and thickness is 5mm.
Below in conjunction with Fig. 4 and Fig. 5, basement bottom board dewatering well well head plugging construction method is made and being illustrated, it comprises the steps:
(1) described sleeve pipe is inserted in dewatering well bellows 2, bellows is filled yellow ground 20 before pipe well shutoff, and sleeve pipe is suitable for reading equal with sole plate 3 end openings;
(2) build bed course 30, for guaranteeing the concrete thickness of sole plate, build bed course anterior cannula and use Steel bar rack temporary fixed, built after bed course, sleeve pipe is just fixed on bed course;
(3), before building sole plate concrete, with wooden model, separating inside and outside flange 12, at sleeve pipe periphery, sole plate reinforcing bar is strengthened processing by strengthening structure;
(4) build sole plate concrete, the concrete of outside of sleeve is built together with sole plate, and now outside of sleeve seal ring plays the effect of first sealing;
(5) concrete in wooden model, after waiting and having drawn water, first cleans out flange surface, places the thick sealing gasket of 3mm, builds cover plate, screws bolt;
(6) build the concrete on cover plate top.
Wherein, the reinforced steel bar ring 40 that described reinforcement structure comprises the additional bar 4 on four limits and is located at additional bar inner side.Described cover plate top strength grade of concrete should improve one-level than sole plate strength grade of concrete, and mixes the expansion agent of 8% ratio (weight), guarantees that concrete does not occur crack at hardening phase.
Adopt above-mentioned construction method to shunt in a well to pipe well, can complete to backfill at basement construction and complete, before ater-casting completes, continue to extract underground water out from basement, after shutoff, the effective height of base plate should be guaranteed.
