Abstract
The invention provides a method for preventing and controlling water leakage in building wall bodies, which comprises the following steps: a plurality of water conducting and ventilating holes with certain depth and used for discharging liquid water or water vapor seeping into the wall bodies are penetrated into the interior of the building wall body from the outer side surface thereof and comprise tail ends and open ends. The slope angle of the central axis of the hole is larger than 0 degree and smaller than 90 degrees and the tail ends of the water conducting and ventilating holes are higher than the open ends thereof; water in the wall bodies exists in a liquid or vapor manner and is discharged from the water conducting and ventilating holes out of the wall bodies. Adopting a conducting method, the method utilizes external forces including air convection, solarization and temperature difference to cause water seeping into the interior of the building wall bodies to be discharged from the arranged water conducting and ventilating holes in time, thus the wall bodies can quickly become dry. Therefore, the method not only can prolong the service life of the building wall bodies butalso has fewer procedures and simpler operation with a blocking method for repairing the leakage of the wall bodies; furthermore, the method has practical significance for ensuring construction quali ty and saving resources.
Description
Technical field
The invention belongs to construction engineering technical field, be specifically related to a kind of method of preventing and treating water leakage in building wall bodies.
Background technology
Construction wall in building course because construction material or construction wrong, or construction wall to expose in atmosphere the time too of a specified duration, be subjected to the role and influence of external force such as Exposure to Sunlight, wind and rain, the temperature difference all the year round, can cause that all leakage appears splitting in construction wall.Especially in the many coastal regions of rainwater, skin to split seepage problem more particularly serious.Because the gas permeability of the facing layer material of external wall such as Ceramic Tiles (layer), painting layer is relatively poor, the moisture content that leaks in the construction wall is difficult to timely discharge, and accumulate in the construction wall and in body of wall to around diffusion, and make construction wall be in dampness for a long time.This not only brings great puzzlement to the user, and damages the exterior wall surface decorative layer, and near the furniture of exterior wall, electrical equipment etc., the deterioration of more aggravating body of wall, and make building prematurely senile, also injure its safety of supply line that is embedded in the body of wall when serious.
At present, the measure that solves the construction wall infiltration mainly is a method of taking shutoff, promptly the water slit, crack on the metope is stopped up with waterproof and sealing material, stop water by construction wall outside infiltrate inner, but owing to the reason that causes seepage is varied, add construction wall especially the exterior wall outdoor surface have drastic change unavoidably, displacement deformation, so method for blocking often can not stop water to infiltrate in the construction wall fully, and takes material consumption worker, also can have influence on the impression of construction wall.
Summary of the invention
The present invention is directed to existing water leakage in building wall bodies and can't in time discharge the problem of construction wall, provide a kind of by constructing ejectment and utilizing cross-ventilation and the external force of Exposure to Sunlight and temperature difference formation, the moisture content that leaks in the body of wall is in time dredged out the outer method of construction wall, make the body of wall that makes moist recover dry in a short time.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be:
A kind of method that is used to prevent and treat water leakage in building wall bodies, it comprises the steps:
(4) on construction wall, wear the ventilative eyelet of most diversions certain depth, that be used for dredging open fire in the body of wall or steam from its lateral surface to its inside, the ventilative eyelet of this diversion comprises end and openend, the inclination angle angle of the central axis of the ventilative eyelet of this diversion is greater than 0 ° and less than 90 °, makes the end of the ventilative eyelet of described diversion be higher than the openend in this hole; Moisture content in the body of wall is discharged outside the body of wall by the ventilative eyelet of this diversion with the form of liquid or gaseous state.
Before above-mentioned steps, it also can may further comprise the steps:
(1) measures the construction wall thickness d;
(2) position of demarcation construction wall percolating water;
(3) according to the central axis and the surperficial angle α of described construction wall of the ventilative eyelet of diversion, calculate the degree of depth X of the ventilative eyelet of diversion, design formulas is as follows: X≤d/sin α, and 20mm≤X＜1/2d, when X＜d/sin α, the described construction wall medial surface of terminal no show of the ventilative eyelet of described diversion is when X=d/sin α, the ventilative eyelet of described diversion penetrates construction wall, its terminal medial surface that arrives described construction wall.
Increase above-mentioned steps, help the constructor to decide the degree of depth of the ventilative eyelet of set diversion according to the infiltration degree of construction wall.When the construction wall infiltration is serious, can suitably increase ventilative its length of eyelet of the diversion that is arranged in the body of wall and density.Described step (4) is at described body of wall percolating water position, and on every side on the outdoor metope in 300～500mm scope, the ventilative eyelet of several described diversions is set.
The ventilative eyelet spacing each other of described each diversion is less than or equal to X.
Also comprise the steps: afterwards in described step (4)
(5) the ventilative eyelet of described diversion is clean with scour without sediment motion, remove dust and gravel;
(6) the openend of the ventilative eyelet of the described diversion that cleans up inwardly greater than 1cm less than the inwall in the 3cm scope on, waterproofing course is set one.
Openend at the ventilative eyelet of described diversion is provided with the ventilative material of non-hydrophily.
The ventilative eyelet of described diversion can be arranged on the seepage place of construction wall or occur the position of seepage easily.
As to improvement of the technical scheme, the central axis of the ventilative eyelet of described diversion is 5～85 ° with the angle between the construction wall vertical centre axis, further preferred 15～65 °.
Beneficial effect of the present invention is: the above-mentioned method that is used to prevent and treat water leakage in building wall bodies, it adopts the conventional measure that connects the ventilative eyelet of water on the existing building body of wall obliquely, the moisture that infiltrates construction wall inside is in time shed by the ventilative eyelet of diversion, avoid moisture content diffusion and alluvial in body of wall, to occur, prolong the application life of construction wall, guaranteed the function of use of building.The infiltration method of taking the ventilative measure of diversion to draw in the construction wall is compared existing method for blocking, not only more reasonable and durable reliable, and it is comparatively economical, therefore the above-mentioned method that is used to prevent and treat water leakage in building wall bodies has solved people and has thirsted for solving but unsolved technical barrier always, obtain beyond thought technique effect, had important and practical meanings.
