Description
Technical field
The utility model relates to technical field of building construction, especially a kind of work of shutting off at round sump foundation pit bottom
Tool.
Background technique
In high-building construction, when ground water pressure is larger, need on sole plate indwelling sump, and in being set in well
Downcomer is set, water pump suction pipe is put into downcomer and is drawn water, is drawn water by water pump concentration and realizes lowering of watertable
Purpose.
When needing to remove precipitation apparatus after foundation construction, the well of sump should be restored to handling at sump
Mouth sole plate.General recovery way is: after stopping precipitation, extracting downcomer out, rubble is filled in sump and pours bottom
Plate.However, since ground water pressure is larger, underground water Yi Congyuan downcomer position and its periphery well it is a large amount of on gush, cause to construct
Difficulty influences poured concrete strength, generates leakage phenomenon, has seriously affected the Quality of recovery of bottom plate.
Summary of the invention
The utility model provides a kind of tool that shuts off at round sump foundation pit bottom, there is construction to solve the prior art
Time is long, waterproof effect is poor, material cost is high, troublesome problem is implemented in operation.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of tool that shuts off at round sump foundation pit bottom, including the steel bushing being vertically centrally placed in sump well
Pipe, steel bushing tube wall outside are welded with two L shape steel plate for sealing water rings, and mouth is welded with round plate under steel sleeve.The steel sleeve is adopted
It is made of hot rolled seamless steel tube, outer diameter is 25mm to 35mm smaller than the internal diameter of round sump.The L shape steel plate for sealing water ring
Thickness is not less than 6 mm, Bian Yikuan 145mm to 155 mm, high 25mm to 35 mm, and one of L shape steel plate for sealing water ring position is in coagulation
On soil padding, two L shape steel plate for sealing water ring positions one of L shape steel plate for sealing water ring top 490mm at 510 mm.
The utility model has the following beneficial effects: construction method is easy, operator does not need to carry out professional training, applies
Work speed is fast, will not influence the construction speed of Other Engineering, and the material used is building site common used material, at low cost, low cost
It is honest and clean, good water-proof effect.To have biggish economic benefit and social benefit.
Detailed description of the invention
Fig. 1 is the vertical section schematic diagram of the utility model.
Specific embodiment
The structure of the utility model and embodiment are described further with reference to the accompanying drawing.
As shown in Figure 1, a kind of tool that shuts off at round sump foundation pit bottom of the utility model, by steel sleeve 1, together
L shape steel plate for sealing water ring 2, two L shape steel plate for sealing water rings 3 and round plate 4 form.Steel sleeve 1 is made of hot rolled seamless steel tube, outside
Diameter is 25mm to 35mm smaller than the internal diameter of round sump.One of L shape steel plate for sealing water ring 2 and two L shape steel plate for sealing water ring 3 are thick
Degree is not less than 6 mm, Bian Yikuan 145mm to 155 mm, high 25mm to 35 mm, and one of 2 position of L shape steel plate for sealing water ring is in concrete
On bed course 10, two L shape steel plate for sealing water rings, 3 position one of L shape steel plate for sealing water ring 2 top 490mm at 510 mm.Steel bushing
Lower mouth is managed to be shut by the welding of round plate 4.
The construction method of this tool that shuts off at round sump foundation pit bottom, steps are as follows:
Step 1: foundation pit is dug to bottom, by the steel bushing with one of L shape steel plate for sealing water ring 2, two L shape steel plate for sealing water rings 3
Pipe 1 is inserted into round sump, and steel sleeve 1 is suitable for reading to be higher by 50 mm of substrate absolute altitude；
Step 2: after concrete cushion 10 is constructed, waterproof layer 5 is affixed into one of 2 tube wall of L shape steel plate for sealing water ring
On, and separately do additional waterproofing layer 6 and rubber fastening band 7, construct base plate waterproofing 5 when, turn to one of L shape sealing on waterproof layer 5
2 bottom of steel plate ring, carries out waterproof shell nosing treatment using lute in, finally carries out underplate concrete 8 and pours；
Step 3: it is poured, is vibrated using micro expansive concrete 11 more impervious than the p6 that underplate concrete 8 is higher by a strength grade
It is closely knit, until pouring overflow lip；
Step 4: it is suitable for reading in steel sleeve 1 using 12 cap sleeve of round plate and interface welding shut, in 1 surrounding of steel sleeve
Js water-repellent paint is brushed, then again pours the use concrete 9 suitable for reading of steel sleeve 1.
