Description
Technical field
The present invention relates to a kind of post-cast strip Novel drainage discharge structure, belong to construction drainage field.
Background technology
At present, in conventional site construction, it is contemplated that cast-in-place concrete is uneven issuable harmful due to temperature, contraction
Crack, should stay in sole plate, wall, beam relevant position and set temporary construction seam, be shunk by component inside, after some time again
Pour and smash the construction joint concrete, structure is linked to be entirety.The construction joint is post-cast strip, and post-cast strip is due to same not with agent structure
When pour, and original structure when designing the concrete stress that bears of post-cast strip region it is just larger, cause base plate or floor be most thin
Weak position.Traditional post-cast strip recharge way is:When pouring the time and preferably selecting temperature relatively low of post-cast strip, can use joints cement
Or mix the concrete of micro aluminium powder in cement, its strength grade should one-level higher than component strength, prevent from going out between New-old concrete
Existing crack, causes weak part.
But such as run into underground water and excessively enrich region, structure self gravitation will be in post-cast strip when can not resisting buoyancy
Region occurs crack, finally destroying fish tail and waterproof layer, causes big face water leakage situation.Meanwhile, after there is structural cracks in post-cast strip,
The reinforcing bar that underground water can be corroded in base plate, occurs fracture with the steel bar stress in base plate backward for a long time, it may appear that the ground in big face
The arch camber of lower room, finally causes the absolute altitude or change in displacement of the only base of cushion cap, causes potential safety hazard.
The content of the invention
It is an object of the invention to:A kind of post-cast strip Novel drainage discharge structure and its construction method are provided, it is existing to solve
After thering is conventional late poured band structure to be subject to groundwater erosion for a long time, structural cracks will be developed into, in the course of time, crack can be by
Flaring is big, infiltration phenomenon occurs, even results in reinforcing bar fracture, and basement arch camber finally causes absolute altitude or the position of the only base of cushion cap
Change is moved, there is a problem of very big potential safety hazard.
To solve the above problems, intend using such a post-cast strip Novel drainage discharge structure, including steel plate for sealing water and band
Sand in shape, is into the deep-slotted chip breaker of " Ω " shape in the middle part of steel plate for sealing water, the length direction of sandstone deep-slotted chip breaker is filled in arc in banding
In groove.

In foregoing discharge structure, the outer surface of geotextiles for wrapping up quartz sand scribbles cement mortar, is sure not to brush blocked up, is ensureing point
While seam porosity, in disturbing concrete, it is ensured that enter parting without substantial amounts of cement mortar, parting is blocked;
In foregoing discharge structure, fast-easy closing-up net is provided with the lower ending opening of the deep-slotted chip breaker of " Ω " shape, in the space of " Ω " shape
After filling the middle sand wrapped up by geotextiles back cover is fixed using fast-easy closing-up net every 500mm and steel plate for sealing water spot welding.
The construction method of above-mentioned discharge structure is as follows:
Step one, pours bed course:Compacted backfill, pours C15 blinding layers, magma letter out, it is ensured that cushion thickness and flatness;
Step 2 waterproofs roll up paving:First to base treatment, surface protuberance is cut, building adhesive is mixed in local dip depression
Polymer cement mortar make up a deficiency it is smooth, construction before first negative and positive angle, wall pipe and post-cast strip press code requirement construct extra play, increasing
One layer 500 wide identical coiled material of patch;
Step 3 fish tail and waterproof layers are constructed:Pour 50mm, C20 pea gravel concretens;
Step 4 plates prick baseplate reinforcing bar;
The steel plate for sealing water construction of step 5 post-cast strips, pours underplate concrete:
A., the mid-plane of steel plate for sealing water 1 is processed into the deep-slotted chip breaker 13 of " Ω " shape, while in the space of deep-slotted chip breaker 13 of " Ω " shape
Fill the middle sand wrapped up by geotextiles, i.e., sand 2 in banding.
B. scribble cement mortar in geotextiles outer surface, be sure not brush it is blocked up, ensure parting porosity while, smash pouring
During concrete, it is ensured that enter parting without substantial amounts of cement mortar, parting is blocked;
C. the interior filling of the deep-slotted chip breaker 13 of " Ω " shape after the middle sand of geotextiles parcel by using fast-easy closing-up net 3 every 500mm and stopping
Back cover is fixed in the spot welding of water steel plate 1.
Step 6 irrigates bottom board concrete:During casting concrete, using than the former higher leveled fine-stone concrete of base plate concrete strength, and add
Plus swelling agent carries out recharge, pour and forbid when smashing barbarous construction, destroy the flow guiding structure of manufacture, it is ensured that the flow guiding structure of manufacture is same
On one line.
Compared with prior art, the present invention is improved to steel plate for sealing water, not only in post-cast strip the old and new's Structural Joint shape
Into reinforcement structure, moreover it is possible to form a weeper drain in post-cast strip, crack along in the weak local development of new and old faying face,
The edge in the presence of groundwater pressure, waterside enters parting french drain along steel plate for sealing water plate body, and discharges baseplate zone, effectively eliminates
Underground water base plate buoyancy, it is to avoid large-scale arch camber and soleplate crack occur.
