Description
Technical field
The utility model relates to a kind of Yield rainfall relation device, and under especially a kind of post, local Yield rainfall relation device under cushion cap, elevator pit, belongs to technical field of building construction.
Background technology
Along with the development of urban construction, adjacent building spacing is more and more less, basement in high rise building construction period, take deep foundation ditch large area well point to have influence on adjacent building foundation settlement, easily cause out-wall crack even building member fracture, therefore gutter can only be set on foundation ditch top, hole end surrounding arranges open drain, keep at a certain distance away and collecting well is set, adopt the submersible pump of more than lift 15m to draw water to gutter, top, hole, after sedimentation basin precipitation, enter municipal Storm Sewer Network.
Problem is, the bottom surface absolute altitudes such as the cushion cap in building, elevator pit are than base plate of foundation pit also dark 2.0 ~ 5.0m, the infiltration capacity of this type of local ground watering is large, directly have influence on construction quality and the safety of dark cushion cap, elevator pit etc., during construction, also need the underground water in these regions to be down to below work plane 300mm.But large-area precipitation is large to the ambient influnence of periphery, entail dangers to, to the safety of slope retaining and adjacent structure, is therefore necessary to further investigate it.
Traditional Yield rainfall relation such as dark cushion cap, elevator pit is all by arranging the interim sump of 300mm × 300mm × 300mm at foundation pit base angles such as dark cushion caps, constantly draw water in the construction technological process such as foundation pad, side, hole brick fetal membrane, reinforcing bar binding, but submersible pump must be taken out before concreting, in result concreting process, the continuous infiltration of underground water still can have a strong impact on the concrete qualities such as dark cushion cap, elevator pit, becomes the hidden leakage defect of basement and elevator cab safe handling.
Summary of the invention
The purpose of this utility model is: for prior art Problems existing, propose a kind ofly effectively to eliminate local Yield rainfall relation device under cushion cap under the post of influence on groundwater underground structure construction quality, elevator pit, thus avoid tradition to build underground water cannot being caused to break through upstream face waterproofing course, infiltrate in underplate concrete thus affect concrete crushing strength and the generation of anti-permeability strength phenomenon by precipitation.
In order to achieve the above object, Yield rainfall relation device of the present utility model comprises sump body, described sump body has bottom cushion, the middle part of described bottom cushion is for filtering material and border is water proof material, the border of described bottom cushion constructs hole wall upward, described hole wall covers the cover plate with draining poling and wire through pipe, the lower end of described draining poling is communicated with the submersible pump delivery port be placed on bottom cushion, and the cable in described wire through pipe is connected with the power end of described submersible pump.
For large quantities of building operations such as communities, Yield rainfall relation device of the present utility model after factory's serial pre-fabrication, can transport job site to.For individual building, also can field fabrication.
During use, under sump body entirety of the present utility model is placed in post, the foundation pit such as cushion cap, elevator shaft base angle falls, draining poling upper end external connection row water pipe, and the cable in wire through pipe connects power supply, submersible pump draining can be started, keep underground water all the time lower than 300mm below work plane.Carry out the concrete pouring construction at the places such as pillar cushion cap, elevator pit afterwards.After construction, sump is permanent stays the end such as cushion cap, elevator pit.
The utility model is adopted to breach in fact the construction method of tradition " bright row's publicly price-reduction ", achieve a kind of brand-new " bright row's secretly price-reduction " construction method by hole in hole, stop to occur swelling phenomenon in concrete initial set process, effectively base plate impact in room under Groundwater is reduced to zero, thus ensure that follow-up Construction Quality.
Further, described draining poling and wire through pipe stage casing tube wall respectively radial direction extend seal ring.
Further, the diameter of described seal ring is 2.5 to 3.5 times of poling outside diameter.
Further again, described draining poling upper end is by the external discharge hose of pipeline connecting parts.

Detailed description of the invention
embodiment one
The present embodiment is lower local, cushion cap hole Yield rainfall relation device under a kind of post, and as shown in Figure 2, the middle part of bottom cushion 5 is gravelly filtering material 8, and border is water proof material.The border of bottom cushion 5 constructs brick hole wall 6 upward, forms sump body thus.Hole wall 6 covers the cover plate 4 that steel plate is made, cover plate 4 is welded with draining poling 9 and wire through pipe 3 by full weld weld seam 7.Lower end and the submersible pump 2(self-priming vacuum pump be placed on bottom cushion 5 of draining poling 9) delivery port is communicated with, and the cable in wire through pipe 3 is connected with the power end of submersible pump 2.
Draining poling 9 and wire through pipe 3 stage casing tube wall weld the radial seal ring extended respectively, and the diameter of seal ring is about three times of poling outside diameter.Seal ring can prevent underground water from gushing on poling, by percolation path by axially changing into radial direction, makes it around to seal ring outer ring, and seal ring outer ring build after and concrete closely build, therefore effectively can suppress seepage.
During use, as shown in Figure 1, the base angle that the device of the present embodiment entirety is placed in cushion cap hole 1 under post is fallen, draining poling 9 upper end is by external discharge hoses 18 of pipeline connecting parts such as straight-through, short tube, bend pipes, wire through pipe 3 draws by straight tube, short tube the cable 17 connecing power supply, submersible pump draining can be started, keep underground water all the time lower than work plane less than 10 300mm.
During construction, reserved construction hole 13, can be drawn water by auto-control submersible pump by water-level probe, thus reaches the object of secretly price-reduction underground water.After submersible pump draining, the colligation of cushion cap gluten can be carried out, the colligation of side base plate double steel bar, water-tight concrete are built, concrete curing, stop pumping afterwards, pipeline connecting parts in reserved construction hole 13 and cable are removed, to screw on plug wire 19, fill out again and water expansive concrete 20, until building base plate 11 all completes (see Fig. 1, Fig. 4).
Facts have proved, " cheating bright row's secretly price-reduction in hole " of the present embodiment, can overcome tradition " bright row's publicly price-reduction " the safe mass hidden danger that underground water brings dark cushion cap and peripheral floor water-tight concrete in concreting, maintenance processes, and equipment and pipeline are installed, constructing operation is convenient, fast, safety.Pipeline connecting parts after dismounting, cable etc. can repeat turnover and use, and in order to carry out in the bottom such as dark cushion cap, local falls the device of therefore the present embodiment, draining, and create more effective, economic, reasonable, safe construction method and lay a good foundation.
Embodiment two
The present embodiment is local Yield rainfall relation device under a kind of elevator pit, and as shown in Figure 5, in figure, 23 is elevator shaft shear wall.The concrete pouring construction at the places such as pillar cushion cap, elevator pit can be carried out.Change concrete formation and the use of Yield rainfall relation device, see embodiment one.
Facts have proved, the use of this device breaches conventional construction method, achieve by " cheating bright row's secretly price-reduction in hole " to guarantee the Expected Results of elevator pit construction quality, stop to occur swelling phenomenon in concrete initial set process, effectively base plate impact in room under Groundwater is reduced to zero.
