Description
Technical field
The utility model relates to building implements, particularly a kind of deep foundation pit precipitation well-sealing device.
Background technology
Along with the development of highrise building, in Construction of Deep Foundation, often can run into underground water problem, particularly in location along the river; the location that underground water enriches especially; when groundwater table is high, the degree of depth is large, have open fire to construct in foundation ditch, this just needs to take well-points dewatering when constructing.After major project has been constructed, need to carry out shutoff to dewatering well, in well-points dewatering well, discharge is enriched sometimes, and hydraulic pressure is large, therefore selects economy, is suitable for, reasonably shut-in well construction equipment is particularly important.Therefore, the improvement of deep foundation pit precipitation well-sealing device is the technical problem needing solution at present badly.
Summary of the invention
For above-mentioned situation, be solve the defect of prior art, the object of the utility model is just to provide a kind of deep foundation pit precipitation well-sealing device, and can effectively solve after prior art well-points dewatering completes, the bad shutoff of dewatering well, easily causes the problem of secondary seepage.
The technical scheme that the utility model solves is, comprise steel plate base, steel sleeve and steel plate for sealing water, steel sleeve upper portion inner tube wall is equipped with interior steel plate for sealing water, corresponding outer tube wall is equipped with outer steel plate for sealing water, steel sleeve tube wall end opening periphery is equipped with steel plate base, outer tube wall between steel plate base and outer steel plate for sealing water is equidistantly provided with stiffener, interior steel plate for sealing water is equipped with flange and flange plate.
The utility model economy, to be suitable for, rationally, good processing, technique are simple, and applicability is strong, install and use easy, construction effect is good, has saved a large amount of engineering cost, save man power and material, can effectively solve after well-points dewatering completes, the bad shutoff of dewatering well, easily causes the problems such as secondary seepage, can effectively save shut-in well expense, effectively ensure that workmanship, for subsequent construction has laid solid foundation, is the innovation on deep foundation pit precipitation well-sealing device.
Accompanying drawing explanation
Fig. 1 is structural profile front view of the present utility model.
Fig. 2 is structural profile top view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Provided by Fig. 1-2, the utility model comprises steel plate base, steel sleeve and steel plate for sealing water, steel sleeve 2 upper portion inner tube wall is equipped with interior steel plate for sealing water 4, corresponding outer tube wall is equipped with outer steel plate for sealing water 3, steel sleeve 2 tube wall end opening periphery is equipped with steel plate base 1, outer tube wall between steel plate base 1 and outer steel plate for sealing water 3 is equidistantly provided with stiffener 9, interior steel plate for sealing water 4 is equipped with flange 7 and flange plate 6.
In order to ensure result of use, described interior steel plate for sealing water 4 is welded on steel sleeve 2 upper portion inner tube wall, and outer steel plate for sealing water 3 is welded on corresponding outer tube wall, and steel plate base 1 is welded on steel sleeve 2 tube wall end opening periphery.
The cylindrical hollow configuration of the both ends open that described steel sleeve 2 is made for hot rolled seamless steel tube.
Described interior steel plate for sealing water 4 lower plane is welded with flange 7, upper plane is placed with flange plate 6, rubber washer 5 is provided with between flange plate 6 and interior steel plate for sealing water 4, the equal one_to_one corresponding of bolt hole on flange 7, interior steel plate for sealing water 4, rubber washer 5 and flange plate 6, is connected and fixed through connecting bolt 8.
Described interior steel plate for sealing water 4, outer steel plate for sealing water 3 and steel plate base 1 are annular.
Described stiffener 9 has 3 at least.
Service condition of the present utility model is, adopt hot rolled seamless steel tube to make steel sleeve 2, steel sleeve 2 is highly not less than concrete floor and cushion thickness sum, and steel plate for sealing water 4 and outer steel plate for sealing water 3 in tube wall weldering suitable for reading, along periphery of spigot full weld; Tube wall end opening weldering steel plate base 1, along periphery of spigot full weld.After completing, the steel plate base 1 of tube wall end opening is placed under foundation pad, then concreting bed course, when reinforcement foundation colligation, stiffener 9 is set on seamless steel sleeve pipe top and welds together with reinforcement foundation.After precipitation completes, by flange 7 full weld on interior steel plate for sealing water 4, in tube wall is suitable for reading, steel plate for sealing water 4 is placed rubber washer 5 then corresponding spiro keyhole position put flange plate 6; Connecting bolt 8 after setting completed, is penetrated bolt hole and tightens by flange 7 and flange plate 6, finally by flange plate and seamless steel sleeve pipe 2 full weld complete and build expansive concrete.
The utility model, by comparing with traditional handicraft, had both decreased material usage and had additionally reduced artificial construction's amount, thus improve construction efficiency, improve economic benefit.Both ensured that the underground water in precipitation can not leak into ground, guarantee quality of shunting in a well, material can be saved again with artificial, efficiently solve well-points dewatering complete after dewatering well be difficult to the technical barrier of shutoff, and accelerate construction speed, save lot of materials, effective reduction of erection time, ensure that workmanship, be the innovation on deep foundation pit precipitation well-sealing device, economic and social benefit is remarkable.
