Abstract
The invention relates to a grouting maintenance construction method for basement roof leakage. The method comprises the steps that a construction position is determined firstly, and then holes are drilled in a structural slab; when a drill bit is in contact with two thirds of the structural slab, hole drilling is stopped, and a grouting head is placed in the drilled holes; a clearance between the drilled holes and the grouting head is blocked through a sealing material (leakage blocking material), and grouting equipment is connected with the grouting head; and the grouting equipment carries out grouting under pressure through the grouting head, and injected grout achieves full grouting and reinforcing on a concrete structural layer (weak part). Therefore, concrete strength and permeation resistance are improved. The method is simple, and the leakage blocking effect is good.
Description
Technical field
The present invention relates to a kind of basement roof seepage slip casting maintenance engineering method.
Background technology
Along with the fast development of society, basement leakage problem has had influence on the normal life of people; Grouting method in the past can not meet the requirement of leak stopping, and seepage place cannot find accurately, wastes a large amount of human and material resources, financial resources.
Summary of the invention
Due to long neglected and in disrepair, usually there is the situation of seepage in basement roof, technical problem to be solved by this invention finds a kind of reasonably grouting for water plugging method, blocked by leakage area.
The technical scheme realizing above-mentioned purpose is as follows:
First layout on structural slab, and then hole, when bit contact stops boring to during 2/3rds position of seepage basal plane thickness, in boring, put into casting head afterwards and fix, then encapsulant (leak stopping the is precious) gap between shutoff boring and casting head is used, grouting equipment is connected with casting head, grouting equipment is by casting head grouting under pressure, the slurries injected are in the full slip casting of concrete (weak part), reinforcing, thus concrete strength, impermeability are improved.
The inventive method is simple, and plugging effect is good.
Accompanying drawing explanation

Fig. 2 is the schematic diagram that casting head inserts in boring
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Fig. 1 and Fig. 2 is the schematic diagram bored on structural slab when putting boring.Concrete defect causes house to leak, and the shape of leakage area has a lot of situation, and such as leakage area is crack, hole, cellular defect etc.
Below with the top board of basement for structural slab 1 describes step of the present invention.
1. the leakage area (namely determining to need the position of construction) of structural slab 1 is first determined, leakage area is certain leakage point 2 or crack 3 normally, area around the position at leakage area place and leakage area forms seepage basal plane, and the dirt near cleaning seepage part, in order to grouting, hole around leakage area, boring forms injected hole 4, when bit contact stops boring to during 2/3rds position of structural slab thickness, if between leakage point relatively far apart, the several injected hole 4 of brill around independent leakage point, if several leakage point location comparison is near, can several leakage point be regarded as one, several injected hole 4 is bored in the periphery of these leakage points, pitch-row between injected hole 4 is 20cm-50cm, the setting of certain pitch-row is not fixing, can set according to the concrete condition of leakage area, the line of injected hole 4 is plum blossom-shaped or circular or arcuate structure, leakage area is surrounded, the effect of such slip casting can be relatively good, when leakage area is fracture shape, the both sides in crack all need to bore injected hole 4, ensure that the slip casting in crack is even, and injected hole 4 can be 5-15cm apart from the distance in leakage point or crack.
2. hole after all completing and place casting head 5 in boring, and the gap between casting head outer rim and boring seals, the gap between encapsulant shutoff boring and casting head can be used, when placing casting head 5, casting head 5 once can insert the bottom of injected hole 4, can in slip casting process, progressively move down casting head, solid to make slurries 6 fill, also further the gap between casting head and boring is filled up, realize sealing;
3. the grout outlet of the grouting equipment of preset pressure is connected with casting head after completing by above-mentioned steps, open grouting equipment afterwards and carry out grouting under pressure, slurries enter in injected hole 4 by casting head under the effect of the pressure, slurries are continued to inject the full leakage area of concrete (weak part), pressurization grouting is stopped when having pure slurries to emerge in the injected hole 4 near leakage area, in the present invention, grouting equipment is leak stopping grouting pump, general grouting pressure 0.3Mpa, injection rate≤0.01L/min.The casting head be connected with grouting equipment grout outlet injects another injected hole 4 be communicated with it by pressure, that says is connected herein, do not refer to and got through between two injected holes, because the position usually leaked, the defect such as crack or hole can extend to concrete position, therefore, when slurries are poured under the effect of the pressure, the minim channel between crack or hole, gap can be got through by the effect of pressure, such slurries flow between two injected holes, fill.
4. then grouting equipment sequentially moves to next place's casting head and proceeds grouting under pressure, carries out forward successively, until all casting heads have slurries to emerge just calculated grouting under pressure;
5. check that leakage area is with or without infiltration after 72 hours, without when infiltration, casting head is fractureed, by fast dry substance, seepage basal plane is closed, floating.
Crack have deeply have shallow, when crack deep (degree of depth in such as crack is more than or equal to 5cm), injected hole 4 is inclined hole, inclined hole through the two ends in crack, and fully fills slurries for making in crack, interval 20-50 minute after 4. step completes, preferred interval about 30 minutes, in crack, carrying out slip casting before grout cures again complete second time slip casting process, because slurries are for solidifying, also can again utilize casting head to be in the milk.
Can according to concrete condition determination grouting pressure, the grouting amount of leakage area when slip casting.
Before searching crack, first answer fracture analysis, and get stamen respectively by the difference of crack width, length, to determine the penetration of fracture rule of development, as non-through crack and the degree of depth is more shallow, can surfacing be done.
Finding crack is loaded down with trivial details a, elaboration, as surface is not easily dry, can dry with blowtorch, and with angle grinding machine polishing periphery, crack place, because of containing moisture content, can find immediately, and namely this way improves operating efficiency, can guarantee that again each subregion is without omission.
Crack repairing: slurries from each piece of casting head 5 (structural facades pours into from lower to upper), when slurries are emerged from injected hole, should should stop immediately, the crack place moved near second piece of casting head 5 continues perfusion, carries out forward successively.In filling process, if slurries have filled adjacent casting head 5 position, can tripping not note; Continue extend or have crack to intersect with it as found after slip casting that two ends, crack still have, should in this position perforations adding, again slip casting.Like this, the first time slip casting in whole piece crack just calculates end.
These are only the preferred embodiment of the embodiment of the present invention; not in order to limit the embodiment of the present invention; within all spirit in the embodiment of the present invention and principle, any amendment done, equivalent replacement, improvement etc., all should be included in the protection domain of the embodiment of the present invention.
