Abstract
The invention discloses a precipitation blocking method for the post-cast strip of a basement baseplate. The invention relates to a basement construction method, and in particular relates to a precipitation blocking method for the post-cast strip of the basement baseplate, which has the advantages of short consumed time, low cost and high efficiency. The precipitation blocking method for the post-cast strip of the basement baseplate is characterized by comprising the following construction steps: setting a water collecting well, cleaning sundries in the post-cast strip, exhausting collected water in the water collecting well, and blocking the collected water with a precipitation well. With the adoption of the precipitation blocking method for the post-cast strip of the basement baseplate, the operation is easy, the construction is convenient and fast, the blocking efficiency of the post-cast strip of the basement can be effectively improved, the strength and the permeability resisting index after the post-cast strip is blocked both can satisfy the construction requirement, the precipitation pumping and discharging speeds are high, the precipitation pumping and discharging effects are good, and the construction progress and the engineering quality can be improved.
Description
Technical field
The present invention relates to the job practices of basement, the basement bottom plate rear pouring tape precipitation method for blocking that especially a kind of time spent is short, expense is few, efficient is high.
Background technology
In building operations, for preventing that monolithic reinforced concrete structure is owing to temperature, the uneven issuable harmful crack of contraction, according to design or job specfication requirement; Stay in sole plate, wall, beam relevant position and to establish interim constuction joint; Structure temporarily is divided into several portions, after shrinking through component inside, behind certain hour, waters again and smash this constuction joint concrete; Structure is linked to be integral body, and the interim constuction joint of this type is called as the ater-casting.
The exterior wall of basement and base plate are all buried underground, receive water in soil and phreatic infiltration, and therefore, the moistureproof and waterproof problem is a major issue to be solved in the design of basement.Usually when the shutoff basement post-pouring zone, need catchmenting in the ater-casting thoroughly be drained, if it is higher to run into groundwater table, catchmenting in the ater-casting is difficult to drain, and can have influence on construction speed and workmanship.
Summary of the invention
To be solved by this invention is exactly to catchment in the present basement post-pouring zone to be difficult to drain, and influences the problem of construction speed and workmanship, and the basement bottom plate rear pouring tape precipitation that a kind of time spent is short, expense is few, efficient is high method for blocking is provided.
Basement bottom plate rear pouring tape precipitation method for blocking of the present invention is characterized in that this method for blocking constructs according to the following steps:
(1), collecting well is set, in the ater-casting, dig the system collecting well, aqueduct is set in collecting well and fills third kind of stone, the collecting well outer wall is filled rubble;
(2), foreign material in the cleaning ater-casting, with the foreign material at constuction joint place in the giant flushing ater-casting, the reparation reinforcing bar is removed the rusty stain on the reinforcing bar simultaneously;
(3), get rid of in the collecting well and catchment, be connected aqueduct with primer pump, utilize interior the catchmenting of aqueduct pump drainage collecting well;
(4), pouring ater-casting concrete, treat to rinse well in the ater-casting, carry out the concrete pouring, carry out concrete curing after pouring finishes;
(5), the shutoff of precipitation well, concrete pouring was accomplished after 24 hours, stopped collecting well and drew water, treat that concrete curing reaches required intensity of engineering design and impervious index after, collecting well and ater-casting are watered shutoff.
It is 500 millimeters that described collecting well is selected diameter for use, and height is 1000 millimeters, and wall thickness is 25 millimeters a concrete prefabricated pipe, and every interval is 100 millimeters on the tube wall, and the inlet opening of 10 millimeters of diameters all is set.
Described aqueduct is connected with primer pump through flange, and the flange position is not higher than the well head that catchments, and shutoff collecting well rear stub locates below ground level, and does not influence outward appearance after the shutoff.
Basement bottom plate rear pouring tape precipitation method for blocking of the present invention; Simple to operate; Convenient and quick construction can effectively improve the shutoff efficient of basement post-pouring zone, and intensity after the shutoff of ater-casting and impervious index all can satisfy construction requirement; The pump drainage speed of catchmenting is fast, effective, improves construction speed and workmanship.
The specific embodiment
Fig. 1 is an ater-casting of the present invention structural representation.
Wherein, ater-casting 1, collecting well 2,3, the third kinds of stones 4 of aqueduct, rubble 5, primer pump 6, flange 7.
Embodiment 1: a kind of basement bottom plate rear pouring tape precipitation method for blocking, and this method for blocking is constructed according to the following steps:
1, in ater-casting 1, dig system collecting well 2, it is 500 millimeters that collecting well 2 is selected diameter for use, and height is 1000 millimeters, and wall thickness is 25 millimeters a concrete prefabricated pipe, and every interval is 100 millimeters on the tube wall, and the inlet opening of 10 millimeters of diameters all is set; Aqueduct 3 is set in collecting well 2 and fills third kind of stone 4, collecting well 2 outer walls are filled rubble 5;
2, foreign material in the cleaning ater-casting 1 with the foreign material at constuction joint place in the giant flushing ater-casting 1, are repaired reinforcing bar and are removed the rusty stain on the reinforcing bar simultaneously;
3, catchment in the eliminating collecting well 2, aqueduct 3 is connected with primer pump 6 through flange 7, utilize catchmenting in the aqueduct 3 pump drainage collecting wells 2; Flange 7 positions are not higher than collecting well 2 well heads simultaneously; After avoiding shutoff collecting well 2, flange 7 is above ground level, influences outward appearance;
4, pouring ater-casting 1 concrete is treated to rinse well in the ater-casting 1, carries out the concrete pouring, carries out concrete curing after pouring finishes;
5, precipitation well shutoff, concrete pouring was accomplished after 24 hours, stopped collecting well 2 and drew water, treat concrete curing reach engineering fixed design strength and impervious index, collecting well 2 and ater-casting 1 are watered shutoff.
