Description

A kind of basement wall and base plate waterproof/drainage structure
Technical field
The utility model relates to a kind of waterproof/drainage structure, and particularly a kind of basement wall and base plate waterproof/drainage structure, belong to building engineering field, is applicable to that groundwater table is high, the basement buried depth is large or the basement waterproof drainage such as anti-drainage requirement height.
Background technology
Basement refers to that the flooring is lower than the architectural space of grade height, along with the development of economic construction and the anxiety of urban land, the use of the underground space more and more is subject to people's attention, because basement residing position is special, more be prone to the phenomenon of percolating water than other buildings, so its anti-drainage performance just seems particularly important.
Cause basement the reason of percolating water phenomenon to occur more, mainly can be summarized as following some:
(1) hydrogeological reason.The basement present position is lower, and when underground water level was higher, underground construction was under the pressure-acting of underground water for a long time, and underground water is changed places and entered indoorly by outer wall of basement and base plate, affects the use of basement.
(2) reason of building self structure.Basement generally adopts reinforced concrete structure, produces a large amount of heats of hydration in uneven settlement of foundation or concrete hydrating process and causes concrete cracking; During construction, concrete vibrating is not enough and honeycomb, pitted skin, hole occur; The quality of the ater-casting of underground construction and deformation joint and exterior wall bottom water flush joint does not reach requirement, local construction casting defectiveness, and waterproof effect is undesirable etc., and above reason all can cause basement leakage.
(3) reason of waterproofing materials.Because the damaged waterproofing course that causes of waterproofing materials lost efficacy; Waterproofing materials and paving material amount do not pass a test, and construction technology is unreasonable, and drainage measure is improper; Waterproofing materials overlap joint imprecision, and form penetrating passage, privileged sites, the Nodes waterproof construction weak link that becomes of poor quality; Basic unit is untreated, and is bonding insecure etc., all can have a strong impact on the water-proof function of waterproofing materials, thereby make basement percolating water phenomenon occur.
The basement leakage problem that causes for above reason, usually adopt at present take " blocking up " as main solution, as adopt high-grade concrete and the strict control heat of hydration and time of setting, improve the site operation quality, to strengthen globality and the density of structure, increase durability and the impermeability of structure self; Select simultaneously the waterproofing materials of high-quality, add the supplementary protection layer, improve the adhesive property of waterproofing course and basic unit etc.Such measures is conducive to improve the anti-leakage performance of basement to a certain extent, yet there are many unpredictable artificial or natural causes in basement in construction and use procedure, in case waterproof construction lost efficacy, to inevitably cause basement Seepage to occur, thereby have a strong impact on the use of basement, and bring great difficulty to maintenance and reinforcement.
In sum, be prone to percolating water phenomenon for basement structure, and traditional counter-measure pays attention to strengthen the waterproof ability of structure more, can not effectively solve when waterproof construction lost efficacy in time with problems such as water eliminatings, be badly in need of at present inventing a kind of anti-drain function that has concurrently, and anti-drainage effect is good, cost is reasonable, speed of application is fast, has the Novel underground chamber waterproof/drainage structure of better economic technology benefit.
Summary of the invention
The purpose of this utility model is to utilize the advantage of existing Basement waterproofing technique, and by increasing discrete material drainage blanket and water discharging body plate, invent and a kind ofly can effectively strengthen basement anti-leakage performance, and can in time get rid of a kind of Novel underground chamber body of wall and the base plate waterproof/drainage structure of percolating water when basement waterproofing structure lost efficacy.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
A kind of basement wall and base plate waterproof/drainage structure is characterized in that at first laying concrete cushion on the basement earth's surface, and one or more catch basins are set in concrete cushion, and catch basin is connected with drainage system;
Build the permanent protection exterior wall by laying bricks or stones; after smearing swabbing cement mortar leveling layer on inner side of outer wall and concrete cushion top; the discrete material drainage blanket that connects inner side of outer wall and concrete cushion top is set; and the draining plate body is set in the discrete material drainage blanket; after discrete material drainage blanket inboard and top arrange coil waterproof layer; in coil waterproof layer inboard and top, topping is set, and in the topping inside edge and the top lay separation layer, build afterwards reinforced concrete floor and interior wall.
Aforesaid basement wall and base plate waterproof/drainage structure is characterized in that the discrete material drainage blanket is paved with whole inner side of outer wall and concrete cushion end face continuously, and draining plate body even interval is arranged in the discrete material drainage blanket.
Aforesaid basement wall and base plate waterproof/drainage structure, it is characterized in that catch basin is inverted trapezoidal, catch basin top cover end face absolute altitude is equal to or higher than absolute altitude at the bottom of the discrete material drainage blanket, be evenly arranged along basement is vertical or horizontal, when catch basin can be built by concrete cushion, headspace forms or adopts the pregroove marks of plastics, steel concrete material, and the anti-filter geotextiles is set on the catch basin top cover.
The utlity model has following characteristics and beneficial effect:
(1) principle that adopts anti-row to combine; good water-proof effect; the setting of permanent protection exterior wall, concrete cushion, coil waterproof layer, separation layer etc. can effectively reduce body of wall and base plate inhomogeneous deformation and when causing the crack to occur, can effectively improve the water resistance of body of wall and base plate.
(2) compare with traditional basement wall and base plate waterproof/drainage structure and be provided with discrete material drainage blanket, draining plate body and catch basin etc., concentrate after can when the waterproof construction partial failure, the underground water that infiltrates being drained into catch basin and discharge, can effectively avoid the underground water of seepage to body of wall and basement bottom board structural damage.
(3) catch basin is arranged in concrete cushion, when adopting the pregroove marks of plastics, steel concrete material, can effectively avoid catch basin distortion and damaged, and improve its durability, at its top cover end face, the anti-filter geotextiles is set, can avoid discrete material and mud etc. to fall into catch basin, and cause catch basin to silt up.
