Work progress of the present utility model and operating principle
During concrete construction as depicted in figs. 1 and 2, basement bottom board drainage drying type anti-row be meant in conjunction with construction technology, only adopt rigid waterproof layer during the base plate construction, and do draining and damp-proof course in the construction level on the basement bottom board face, the part infiltration discharge in time that occurs in the base plate is taken away, reach the effect of anti-row combination, thereby guarantee basement bottom board face drying, nothing infiltration.
The utility model is to constitute like this: lowermost layer is the rigid waterproof layer made from the impervious reinforced concrete structure base plate of S8 1, the concrete disintegrating slag backfill layer 2 that one deck 150 millimeters thick are arranged on rigid waterproof layer 1, be provided with the cement aggregate chips layer 3 of 70 millimeters thick on concrete disintegrating slag backfill layer 2, this layer is tamped with machinery; Being the damp-proof course made from the plastic sheeting of two-layer 1 millimeters thick 4 on cement aggregate chips layer 3, is the surface layer 5 of 80 millimeters thick made with the C25 concrete on the damp-proof course 4, and surface layer 5 placing and trowelings are flat, use mechanical polishing.Above-mentioned each layer constitutes the terrace of basement.Terrace is provided with gutter 6, and gutter 6 is connected with collecting well 7, is provided with filter pipe 8 and the gutter 9 that is connected with gutter 6 at concrete disintegrating slag backfill layer 2.
When carrying out the construction in gutter 6, at first build the furrow bank 10 of 30 cm thicks by laying bricks or stones with high sand according to position, drawing gutter, stop the concrete disintegrating slag to flow into gutter 6 as the retaining bank with infiltration.The degree of depth in gutter 6 is to rigid waterproof layer 1, and the bottom of trench in gutter 6 is provided with 5% the gradient, and gutter 6 is a minimum point with the junction of collecting well 7.
When carrying out the construction of concrete disintegrating slag backfill layer 2, broken concrete is mainly adopted in basic unit's backfill, and size is a 20-120 millimeter chunky shape, after the water flushing, is used for backfill.
When carrying out the construction of gutter 9, as shown in Figure 5.After basement drain ditch and the backfill of concrete disintegrating slag are finished, establish 200 millimeters gutters 9 of diameter 32 millimeters long every 3 meters, in gutter 6, look for slope 5%, the water inlet that is embedded in the backfill layer has wrapped up geotextiles 13, prevents that the aggregate chips fine sand from flowing in the gutter 6.Be provided with gutter 9 in the backfill layer, mainly guide the interior percolating water of base plate to flow, avoid this part water to cause ground humidity or hollowing cracking in building backfill layer inner accumulated to gutter 6.When burying gutter 9 underground, as shown in Figure 3, should build the brick of 120 millimeters thick by laying bricks or stones in gutter 9 both sides, highly slightly high 50 millimeters than gutter 9, the outer aggregate chips layer that fills up of pipe, gutter does not break during with the assurance concreting.
The sloping layer construction
Become cement stone dust slag (cement mixing content is a weight ratio 6%) that concrete disintegrating slag slit is filled with cement mixing with stone flour, and do the sloping construction of looking for of 70 millimeters thick.At first require the workman by with cement stone dust proportionally requirement both are stirred, again mixture is filled in the concrete disintegrating slag space, increase the backfill layer compaction rate.
The underground run off construction
After the cement aggregate chips layer compacting that backfill is good, carry out the construction of backfill layer underground run off.At first as shown in Figure 4.Every 50 centimetres of treatment holes 11 that cut out 30 * 50 millimeters, treatment hole 11 external surfaces cover to be gone up close order safety net 12 and fastens with the pvc pipe of 32 millimeters of 6 meters long diameters, and purpose is to prevent when allowing water flow into that the aggregate chips coarse sand runs off.Dig out covered conduit at backfill layer then, bury filter pipe 8 underground, spacing and the gutter 9 identical (generally being no more than 3 meters) that leads to the open drain adopt rubble to carry out backfill all around, and geotextiles is laid on top, cover fine sand on it.Filter pipe 8 and gutter 9 are connected, made the ponding in the covered conduit flow into the open drain by gutter 9.After covered conduit construction finished, again backfill layer and sloping layer are tamped.
4 constructions of plastic sheeting damp-proof course
Lay layer of plastic film damp-proof course 4 after the compacting from the teeth outwards, and plastic sheeting is bonded to integral body, prevent that underground aqueous vapor is dissipated in the basement by concrete pavement with adhesive tape.
The concrete construction of concrete pavement 5
Magma mechanical polishing machine is adopted in the ground press polish.All are smeared line flatten press polish, it is closely knit bright and clean to reach facing surface.
The setting of ground lattice seam
Concrete separating crack cutting principle is that post cuts with post centering, when area is divided into 2 or 4 with it during greater than 36 square metres, makes and cuts apart concrete area less than 36 square metres.The Concrete Construction seam stays as far as possible and is located at the pillar middle part, cuts after this position construction is finished again, and can guarantee the attractive in appearance of constuction joint position.Lattice seam is divided into main lattice seam and cutting lattice seam, and the lattice seam stays and is located on the surface layer concrete, treats in time to carry out the partitioning slot construction after concrete reaches 50% intensity, and suggestion rose after concreting and begins cutting in 3 days.
