Abstract
A basement watertightness structure and a construction method thereof belong to the technical field of watertightness of construction structures of buildings. The watertightness structure mainly consists of plain soil (1), a plain concrete backing layer (2), an impervious concrete bottom plate (3), a graded gravel hydrophobic layer (4), a non-woven fabric isolation layer (5), a reinforced concrete surface layer (5), a gutter (7), a PVC (polyvinyl chloride) water drainage pipe (8), a brick wall (9) and a basement outer wall (10). The construction method of the basement watertightness structure is simple and easy to operate, the problems of water seepage and leakage of a basement can be effectively solved, and particularly, water seeping into the basement or semi-basement can be drained out in time without affecting using functions of the structure on the condition that the bottom plate of the basement has cracks and cannot be handled, and watertightness construction quality can be guaranteed.
Description
One, technical field
A kind of basement waterproofing structure construction and job practices belong to building operations structurally waterproof technical field.
Two, background technology
Along with quickening of urbanization process; Consider aspect needs such as enlarging usage space and stable building foundation; Increasing building has been built basement in the city; And area constantly enlarges, the degree of depth constantly increases, basement bear whole loads of building and with Load Transfer to soil layer, its steadiness to the building safety and service life significant.Basement enlarges extremely people's welcome of effect of usage space with it, but because it is built underground, therefore, the buildings waterproof performance just will directly affect the bulk life time of the behavior in service and the building of basement.The basement leakage problem belongs to the leakage in " four leak " in the construction work; Be roofing, washroom, big plate construction panel seam and basement leakage; That seepage has become is ubiquitous in China's building " pain disease ", for this reason the whole nation be used for every year buildings waterproof do over again with maintenance cost up to more than 500,000,000 yuan.The expense that is used to solve the basement leakage problem is high especially.
China's urban architecture basement waterproofing mainly is indoor in order to prevent that underground water and occluded water from infiltrating, and influences indoor ordinary production, work, life and storage environment and makes.The design and construction of basement waterproofing engineering often follow " anti-, row, cut, stifled combining, temper toughness with gentleness, suit measures to local conditions, the principle of the comprehensive regulation ", accomplish row's rear defence earlier, promptly at first ponding can not be arranged, water is discharged at short notice swimmingly.The traditional method of basement waterproofing engineering is paving waterproof roll or a brush water-repellent paint on the concrete bed course.People place the hope of waterproof on the waterproofing materials on always, and waterproofing materials is constantly research renewal also.Once the heat posted asphalt felt, polyethylene polypropylene SBC-120, the cement-base infiltration crystallization coating that occurred in succession, and at present comparatively general self-adhering-type SBS modified asphalt felt or the like.But the seepage key because the research and development of new material are not hited so not only do not solve root problem, the trouble waters of material market once occurred on the contrary, made waterproof work increase new unfavorable factor.
See that from the basement of the finding part that leaks water leaks out by the concrete weak part of basement structure.It has explained the problem of two aspects: the one, and the rigid self-waterproof partial failure of basement structure; The 2nd, the overall flexibility waterproofing course that is made up of waterproofing materials also destroys.Judge that from convention rigid structures has plenty of at same position from waterproof partial failure and flexible waterproof layer local failure; But most cases can be at same position, and this is owing to underground water after the flexible waterproof layer local failure can pass flexible waterproof layer, gets into the outer wall of deck; Under the effect of groundwater pressure; Water can be between flexible waterproof layer and structural concrete external surface, the passage of riving, when run into structural concrete from the waterproof failure position time penetrate concrete and get into basement and produce seepage.Therefore when it is found that basement leaks, the structure of its basement is from waterproof and flexible waterproof layer all existing local inefficacy and destruction.According to different structure aspects, it is improper etc. that the reason that basement leaks can be divided into the partial failure of structural concrete rigid self-waterproof, flexible waterproof layer local failure and architectural detail structure.
Three, summary of the invention
The technical problem that the present invention will solve is: provide to overcome the problem that prior art exists; Can solve basement, partly-exposed basement ponding seepy question effectively; Can in time underground water be discharged basement, keep basement, dry, long-pending a kind of basement waterproofing structure construction and the job practices of leaking of nothing of partly-exposed basement.
The technical solution adopted for the present invention to solve the technical problems is: a kind of basement waterproofing structure construction and job practices is characterized in that: whole structure is made up of plain soil (1), plain concrete bed course (2), water-tight concrete base plate (3), graded broken stone drainage blanket (4), nonwoven separation layer (5), steel concrete surface layer (6), gutter (7), PVC gutter (8), barricade (9), outer wall of basement (10); Plain soil (1) needs compacting, tamps to compactness to be not less than 93%; Plain concrete bed course (2) thickness is 100mm, concrete strength grade C15; Water-tight concrete base plate (3) structure is suffered from one's own actions slope 0.5%, and impervious grade must not leave constuction joint when building by designing requirement, build accomplish after watering maintenance in 7 days; Graded broken stone drainage blanket (4) is 100 thick, links to each other with gutter (7) with PVC gutter (8); Gutter (7) width is 200mm, highly is graded broken stone drainage blanket (4)+nonwoven separation layer (5)+steel concrete surface layer (6), and drainage grade is 0.5%; PVC gutter (8) diameter is 32mm, tilts 15% by graded broken stone drainage blanket (4) to gutter (7), and (7) are every along the gutter is provided with one at a distance from 1500mm, and the water in the graded broken stone drainage blanket (4) is dredged gutter (7); Nonwoven separation layer (5) adopts 120G/M
2Steel concrete surface layer (6) is joined Φ 4200 two-way concrete slab nets for the thick C25 concrete of 100mm, and with smashing with troweling, per 6 * 6m is provided with the wide shrinkage joint of 4mm, cutting-in 20mm, and clog with the polyurethane ointment; Steel concrete surface layer (6) adopts mechanical finisher compacting to receive light; Thick brick wall of 120mm or the thick concrete wall of 120mm (9) are set between gutter (7) and the outer wall of basement (10).
The concrete job practices of the present invention:
1. plain soil (1) is tamped to compactness >=93%, builds the plain concrete bed course (2) of C15;
2. outer wall of basement (10) and water-tight concrete base plate (3) concrete are built in outer wall of basement (10) formwork, assembling reinforcement;
3. lay 100 thick graded broken stone drainage blankets (4), the every separated pre-buried Φ 32PVC gutter of 1500mm (8) of periphery also stays and establishes the wide gutter of 200mm, builds the thick brick wall of 120mm by laying bricks or stones or builds 120mm concrete wall (9);
4. lay 120G/M
2Nonwoven separation layer (5);
5. build 100 thick C25 concrete and join the steel concrete surface layer (6) of Φ 4200 two-way concrete slab nets.
Compared with prior art, the beneficial effect that the present invention had is: a kind of basement waterproofing structure construction and job practices have good water-proof effect, can guarantee that basement does not have ponding, in time discharge underground water.Brought into play anti-draining usefulness effectively, and can the crack occur, can't play structure under the unfavorable conditions of waterproof, in time percolating water has been discharged, do not influenced the basement function of use at basement bottom board.
