Abstract
The utility model discloses a drainage anti-floating system used for a basement in construction period. The drainage anti-floating system is characterized in that a basement concrete floor is provided with a vertical drainage circular steel tube, the upper end of the drainage circular steel tube is provided with a circular steel tube cover, the lower end of the drainage circular steel tube is provided with a steel tube filtering net, the outer side wall of a basement concrete wall is provided with a vertical catchment steel tube, water leaking holes are arranged in the vertical catchment steel tube, one end of an L-shaped steel tube water level observation branch pipe penetrates through the basement concrete wall and is communicated with the vertical catchment steel tube, and the other end of the L-shaped steel tube water level observation branch pipe is communicated with a plastic water level reading pipe through a plastic pipe jointing element. Compared with the background art, the drainage anti-floating system has the advantages that water level can be monitored in real time, measures of anti-floating treatment can be taken in time, the element is simple, the construction is convenient, the cost is low, and no influence is caused on the use of an original structure.
Description
Technical field
The utility model relates to building field, relates in particular to a kind of drainage and anti-float system for the construction period basement.
Background technology
Along with the acceleration of urbanization process, the use of multi-rise building is promoted day by day, so that the basis is embedding more and more darker, more has the basement part of square formula building to use as functional buildings such as garages.Yet since when design the deficiency estimated of groundwater table, the factor that suffers heavy rain suddenly so that groundwater table is uprushed etc. causes pile foundation tension Lack of support, causes basement the crack to occur and structure is scrapped.Using at present more counter-measure is to set up uplift pile and anchor pole, top ballast balance buoyancy, drainage dewatering and basement boring draining.
But also there is following problem in it:
1) uplift pile and anchor pole cost are higher, need basement is anchored to underground soil layer and penetration concrete, have increased the complexity of construction, can not solve a problem promptly.
2) for large-area basement, top ballast method construction speed is slow, labor intensive, be difficult to process prominent suffer heavy rain so that groundwater table is uprushed event.
3) it is slow that drainage reduces basement periphery groundwater table speed, also be difficult to process prominent suffer heavy rain so that groundwater table is uprushed event.
4) above-mentioned several processing method all is the treatment measures that adopt behind the basement anti-floating scarce capacity when finding, basement bottom board has floated and the concrete cracking phenomenon occurred at this moment, even process successfully and can not so that original basement structure restores to the original state fully, bring irreversible destruction.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and a kind of drainage and anti-float system for the construction period basement is provided.
The drainage and anti-float system that is used for the construction period basement comprises vertical drainage round steel pipe, round steel pipe lid, steel pipe filter screen, vertically catchment steel pipe, L shaped steel pipe water-level observation arm, plastics water level reading tube, plastic conduit connecting elements, concrete of basement base plate, permeable hole, basement uplift pile, basement concrete wall wall; Be provided with the basement concrete wall wall around the concrete of basement base plate, concrete of basement base plate soffit is provided with the basement uplift pile.
The concrete of basement base plate is provided with the vertical drainage round steel pipe, draining round steel pipe upper end is provided with the round steel pipe lid, draining round steel pipe lower end is provided with the steel pipe filter screen, basement concrete wall wall lateral wall is provided with the steel pipe that vertically catchments, vertically catchment and offer permeable hole on the steel pipe, L shaped steel pipe water-level observation arm one end passes the basement concrete wall wall and is connected with the steel pipe that vertically catchments, and the L shaped steel pipe water-level observation arm other end is connected with plastics water level reading tube by the plastic conduit connecting elements.
The utility model is compared the beneficial effect that has with background technology:
1) adopt law of connected vessels to construct the water-level observation system, can the Real-Time Monitoring water level, in time take the anti-floating treatment measures.
2) used and can open at any time and the round steel pipe drainage system of closing, simple operation is rapid, has avoided basement bottom board the destruction of the unrepairables such as concrete cracking and come-up to occur, saves the workload of boring after the come-up of floor and fills up the follow-up work of hole.
3) member is simple, only needs reserving hole when concrete of basement is built, easy construction, and cost is low, on the not impact of use of original structure.
Description of drawings
Fig. 1 is the section of structure of drainage and anti-float system;
Among the figure: vertical drainage round steel pipe 1, round steel pipe lid 2, steel pipe filter screen 3, vertically catchment steel pipe 4, L shaped steel pipe water-level observation arm 5, plastics water level reading tube 6, plastic conduit connecting elements 7, concrete of basement base plate 8, permeable hole 9, basement uplift pile 10, basement concrete wall wall 11.
The specific embodiment
As shown in Figure 1, the drainage and anti-float system that is used for the construction period basement comprises vertical drainage round steel pipe 1, round steel pipe lid 2, steel pipe filter screen 3, vertically catchment steel pipe 4, L shaped steel pipe water-level observation arm 5, plastics water level reading tube 6, plastic conduit connecting elements 7, concrete of basement base plate 8, permeable hole 9, basement uplift pile 10, basement concrete wall wall 11; Be provided with basement concrete wall wall 11 around the concrete of basement base plate 8, concrete of basement base plate 8 soffits are provided with basement uplift pile 10.
Concrete of basement base plate 8 is provided with vertical drainage round steel pipe 1, draining round steel pipe 1 upper end is provided with round steel pipe lid 2, draining round steel pipe 1 lower end is provided with steel pipe filter screen 3, basement concrete wall wall 11 lateral walls are provided with the steel pipe 4 that vertically catchments, vertically catchment and offer permeable hole 9 on the steel pipe 4, L shaped steel pipe water-level observation arm 5 one ends pass basement concrete wall wall 11 and are connected with the steel pipe 4 that vertically catchments, and L shaped steel pipe water-level observation arm 5 other ends are connected with plastics water level reading tube 6 by plastic conduit connecting elements 7.
When the utility model is implemented, vertical drainage round steel pipe 1 is embedded in concrete of basement base plate 8 in advance, and L shaped steel pipe water-level observation arm 5 is embedded in basement concrete wall wall 11 in advance, when precipitation, by observing the reading of plastics water level reading tube 6, determine whether to open round steel pipe lid 2, determining that need to open round steel pipe covered, and entered in the basement water at 2 o'clock, reach the balance of the inside and outside hydraulic pressure of basement, avoid the basement bottom board cracking, after outdoor water level descends, take out the water in the basement; Set the anti-floating water level
