Abstract
The utility model provides a basement and semi-basement waterproof structure and belongs to the technical field of building construction structure waterproof technologies. The waterproof structure mainly consists of plain soil (1), a plain concrete cushion layer (2), an anti-permeability concrete base plate (3), a graded broken stone drainage layer (4), a non-woven fabric isolating layer (5), a reinforced concrete pavement layer (6), a drainage ditch (7), a polyvinyl chloride (PVC) drainage pipe (8), a retaining wall (9) and a basement outer wall (10). A construction process is simple and easy to operate, and the problems including water permeability and water leakage of basements can be effectively solved. Under the condition that cracks on basement base plates cannot be solved, water permeating the basements and semi-basements can be timely drained out, using functions of the structure are not influenced, and the quality of waterproof construction is ensured.
Description
One, technical field
A kind of basement and partly-exposed basement waterproof construction structure belong to building operations structurally waterproof technical field.
Two, background technology
Quickening along with 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 the whole load 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 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, large panel building plate seam and basement leakage, seepage has become ubiquitous in China's building " pain disease ", and the annual buildings waterproof that is used in the whole nation is done over again with maintenance cost up to more than 500,000,000 yuan for this reason.The expense that is used for solution 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 affects indoor normal production, work, life and storage environment and makes.The design and construction of basementwaterproofing often follow " anti-, row, cut, stifled combining, temper toughness with gentleness, suit measures to local conditions, the principle of the comprehensive regulation ", accomplish to arrange first rear defence, namely at first ponding can not be arranged, water be discharged at short notice swimmingly.The traditional method of basementwaterproofing is paving waterproof roll or 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 in succession occurred, and at present comparatively general self-adhering-type SBS modified asphalt felt etc.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.
From the basement leaking part of finding, water leaks out by the concrete weak part of basement structure.It has illustrated 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 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, this is owing to underground water after the flexible waterproof layer local failure can pass flexible waterproof layer, enter 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 enter basement and produce seepage.Therefore when it is found that basement leaking, the structure of its basement all has local inefficacy and destruction from waterproof and flexible waterproof layer.According to different structure aspects, it is improper etc. that the reason of basement leaking can be divided into the partial failure of structural concrete rigid self-waterproof, flexible waterproof layer local failure and architectural detail structure.
Three, utility model content
The technical problems to be solved in the utility model is: provide to overcome the problem that prior art exists, can effectively solve basement, partly-exposed basement ponding seepy question, can in time underground water be discharged basement, keep basement, partly-exposed basement dry, leak a kind of basement and partly-exposed basement waterproof construction structure without long-pending.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of basement and partly-exposed basement waterproof construction structure is characterized in that: whole structure is comprised of element 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); Element soil (1) needs compacting, tamps to compactness to be not less than 93%; Element concrete bed course (2) thickness is 100mm, and strength grade of concrete is 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 finish after watering maintenance in 7 days; Graded broken stone drainage blanket (4) is that 100mm is 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, (7) tilt 15% to the gutter by graded broken stone drainage blanket (4), (7) arrange one every 1500mm along the gutter, 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 the thick C25 concrete matched of 100mm Φ 4 200 two-way concrete slab nets, and with smashing with troweling, per 6 * 6m arranges 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; The 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 utility model concrete construction method:
1. element soil (1) is tamped to compactness 〉=93%, builds C15 element concrete bed course (2);
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 the thick graded broken stone drainage blanket of 100mm (4), periphery is every the pre-buried Φ 32mmPVC gutter of 1500mm (8) and stay and establish the wide gutter of 200mm, builds the thick brick wall of 120mm (9) by laying bricks or stones;
