concrete

19,32 is the closedtop anti-seepage method, it is side form that the closedtop lumps of wood promptly is set, at the new-old concrete seam crossing with glue with joint seal, and with certain thickness concrete joint seal glue is buried and to protect, to prolong the aging period of sealing.Sealing compound is formed by three layers, and lower floor is a sealing compound, and the middle level is the fixing glue of lower floor's sealing compound, and the upper strata is the sealing glue of middle level glue.Three layers of sealing compound must could pour into layer concrete after the body contraction is all finished, adopt slightly expanded concrete that layer concrete is fully combined with the both sides concrete, and use plate vibrator jolt ramming.When cast ater-casting concrete, must make the back pouring concrete than the low visible height of first pouring concrete, make sealing compound be enclosed in true seam position and about extend a width, seal effect to reach desirable glue.When the pouring concrete of back, also can establish the seam lath at seam crossing.33,35,37 all represent hole to be provided encapsulating method among the figure, and 33 is the vertical hole vertical with seam, and 35 is the horizontal hole in parallel hole, 37 is the vertical hole in the parallel hole, vertical hole encapsulating effect is better than parallel hole, and it is not subjected to the colloid effect of contraction, can select the unexpansive glue of high strength for use.Hole to be provided encapsulating method is for pouring concrete construction back, back the method that infiltration is taked to take place, after the concrete construction of ater-casting, if not having infiltration takes place, encapsulating not, if seep water, can be successively from hole for injecting glue to hole to be provided inner high voltage encapsulating, owing to colloid has certain viscosity and cohesive strength, can displace infiltration and make colloid be full of hole to be provided, the employed hydration reaction glue of encapsulating can stand and end the infiltration continuity.34 are the only glue method that expands, promptly adopt the water-swellable clay, before the adhesive tape concrete pouring of back, clay is pressed into plastic tank, after the pouring concrete cast of back, the surface of expansion glue and the water in the concrete react to expand seam are blocked, colloid remains unchanged for a long time, when underground water when seam rises to expansion glue place, colloid continues to react infiltration is ended.Must before the concrete pouring of ater-casting, clay be pressed into plastic tank during construction, and can not after side form is removed, promptly embed clay, prevent the construction water etch and colloid was lost efficacy, guarantee that clay can not meet water before concrete pouring.36 are spray glue sealing method, promptly the organosilicon of the side elevation of pouring concrete spray formerly height permeates glue earlier, it can be with calcium hydroxide reaction in water and the concrete and produces gel, first pouring concrete side elevation top layer micropore is sealed, at back pouring concrete forward direction elder generation pouring concrete surface spray glue, spray glue is controlled at downward drip and exceeds, owing at first spray glue first pouring concrete surface micropore is all sealed, and institute sprays glue the following time and all stays first pouring concrete surface.When back pouring concrete is poured into a mould,, under the concrete lateral pressure effect, can not connect the face place and form glue-line at new-old concrete because the viscosity of colloid is very little.After the back pouring concrete cast, the water on colloid and pouring concrete surface, back and calcium hydroxide react and produce gel, gel is the slit of fill concrete seam crossing at first, and pouring concrete deep infiltration backward then is the interface micropore sealing of back pouring concrete at concrete seam.Like this, spray glue is both with the concrete surface micropore sealing of concrete joint both sides, and dimension one possibility passage---the joint sealing that will seep water again reaches the sealing purpose.

Advantage of the present invention and effect are as follows:

1, owing to adopted the cloth die support, solved the support problem of post-cast strip side form, no matter the post-cast strip chi Very little have muchly, and the post-cast strip place that can both formerly water coagulation figure arranges smooth and reliable side form, makes first pouring concrete Smooth-sided compression candles at the place, post-cast strip is closely knit, and rear pouring concrete can fully tamp the post-cast strip, and this is just reliable for obtaining The basement anti-seepage effect lay the first stone.

2, owing to adopted new post-cast strip rubber seal anti-seepage method, new-old concrete seam and seam two have been eliminated The hole of side concrete surface layer is sealed the passage that may seep water effectively, reaches reliable antiseepage Effect.

3, reserve the injecting glue hole the middle airbag method that adopts is set, in the new-old concrete of post-cast strip, form a silkworm Beans shape hole to be provided, this hole to be provided size is bigger, and it is wide to fill with material ranges, and important engineering is adapted to especially.

4, plastic tank cloth mould is formerly set up smooth smooth plastic tank in the side, post-cast strip of pouring concrete, will The expansion clay is pressed in the plastic tank reliably, has stopped the generation of rear pouring concrete parcel expansion clay, with passing The clay mounting method of system is completely different.

5, the closedtop anti-seepage method is taked twice construction of rear pouring concrete, and not only the colloid sealing effectiveness is better, and Simple to operate, the complex process may seep water the time becomes normal concrete construction.

6, glue spraying sealing method both with the concrete surface micropore sealing of concrete joint both sides, will seep water again Dimension one possibility passage---joint sealing, the seam between the very effective sealing new-old concrete of energy.

Very complicated processing became simple injecting glue when 7, concrete joint percolating water will take place the hole to be provided slip casting method, as convenient falling to starch in the bottle of going together, and this at home and abroad is beyond example.

8, method easy construction of the present invention, waterproof effect is reliable, but construction costs is lower than existing waterproof measure on the contrary, is best both at home and abroad at present ater-casting percolation-proof method.
