Abstract
The invention discloses a waterproof construction method for setting a rubber waterstop at the bottom of a large reinforced concrete raft foundation. The method comprises the following steps of: before constructing at the construction joint of a large reinforced concrete raft foundation, for waterproof treatment, paving a layer of geotextile on a plain concrete cushion; paving a layer of PVC (polyvinyl chloride) waterproof coil on the geotextile; sticking a rubber waterstop at the construction joint of the PVC waterproof coil; paving a grouting pipe on the rubber waterstop; applying 1:3 cement mortar at other parts with the PVC waterproof coil; and then binding the steel bars and pouring concrete. The construction method is safe and reliable in use, overcomes the defect that the conventional construction needs to weld a steel bar skeleton, shortens the working period, saves materials and lowers the cost.
Description
Technical field
The invention belongs to the civil engineering technical field, when being specifically related to steel concrete raft foundation employing ater-casting or the method construction of piecemeal jumping storehouse, the job practices of rubber fastening band waterproof is set in the raft foundation bottom.
Background technology
When building need make full use of the underground space, the general steel concrete raft foundation that adopts in the basis of its building, therefore, the area of steel concrete raft foundation is all bigger, and requires waterproof.Because reinforced concrete foundation is bigger; Maximum can reach 200m * 200m, in design, generally adopts the ater-casting to solve the concrete shrinkage problem; Also can large-scale raft foundation piecemeal be taked to build " piecemeal is jumped the storehouse method " of reserving one and solve the concrete shrinkage problem.But, along the middle part of short transverse steel plate or rubber fastening band to be set all at constuction joint concrete place and carry out waterproof no matter adopt which kind of method construction.At steel concrete raft foundation constuction joint place when short transverse is provided with steel plate or rubber fastening band; Because the position that steel plate or rubber fastening band are provided with is in the centre of concrete floor thickness; Therefore; In the construction, in order to ensure the accuracy of waterstop position, general welded reinforcement fixed mount is fixed steel plate or rubber fastening band.
Summary of the invention
The purpose of this invention is to provide a kind of steel concrete raft foundation bottom the rubber fastening band waterproof construction method is set; This job practices with the waterstop at reinforced concrete construction seam place by being arranged on the centre position of constuction joint place along short transverse; Change into and be arranged on concrete base, and all adopt rubber fastening band, simultaneously; Increase grout pipe, prevented to have built the processing when the constuction joint place leaks behind the concrete.
The present invention seeks to realize like this: a kind of steel concrete raft foundation bottom is provided with the rubber fastening band waterproof construction method; Its main feature is: before the construction of large-sized reinforced concrete raft foundation; In order to solve the steel concrete shrinkage problems; The ater-casting is set usually, or large-sized reinforced concrete is blocked into the blockage of 40m * 40m, adopt at a distance from " piecemeal is jumped the storehouse method " of building a block concrete and construct; No matter adopt ater-casting or " piecemeal is jumped the storehouse method " construction, waterproofing work all will be done by its constuction joint place; Waterproofing work is one deck geotextiles on the plain concrete cushion layer upper berth earlier; One deck PVC waterproof roll on the geotextiles upper berth; Paste rubber fastening band at PVC waterproof roll constuction joint place; On rubber fastening band, lay Grouting Pipe, smear the 1:3 cement mortar, assembling reinforcement then, concreting at the position of other PVC waterproof rolls.When the concrete of building moulding when drainage is found in use, just can utilize the Grouting Pipe of burying underground the caulking joint of being in the milk, reach the purpose of control combination.
Steel concrete raft foundation proposed by the invention bottom is provided with the rubber fastening band waterproof construction method, with steel concrete raft foundation middle part steel plate is set or the rubber fastening band waterproof construction method is compared, and is simple and practical; Rational in infrastructure; Safe and reliable, changed the disadvantage that conventional construction needs the welded reinforcement skeleton, the reduction of erection time; Economical with materials reduces cost.
Combine accompanying drawing and instance that steel concrete raft foundation bottom proposed by the invention is provided with the rubber fastening band waterproof construction method is described further at present.
Description of drawings
Fig. 1 is that this steel concrete raft foundation proposed by the invention bottom is provided with rubber fastening band waterproof construction method constuction joint place waterproof generalized section.
Among the figure: 1. clay; 2. plain concrete cushion layer; 3. geotextiles; 4. PVC coil waterproof layer; 5. mortar levelling layer; 6. after-pouring concrete; 7. raft foundation lower floor two-way concrete slab; 8. horizontal grouting pipe; 9. vertical Grouting Pipe; 10. rubber fastening band; 11. raft foundation upper strata two-way concrete slab; 12. first concreting.
The specific embodiment
As can be seen from Figure 1: steel concrete raft foundation bottom is provided with the rubber fastening band waterproof construction method, it is characterized in that: earlier at raft foundation bottom treatment clay 1, make it satisfy the requirement for bearing capacity of design demand; On clay 1, build the thick plain concrete cushion layer 2 of 100mm again; On plain concrete cushion layer 2, lay geotextiles 3; On geotextiles 3, lay PVC coil waterproof layer 4; Do not laying the thick 1:3 mortar levelling of laying 40mm layer 5 on the position PVC coil waterproof layer 4 of the wide rubber fastening band 10 of 250mm; On concrete construction joint bottom, PVC coil waterproof layer 4, lay the wide rubber fastening band 10 of 250mm, on rubber fastening band, lay horizontal grouting pipe 8, every interval 10m is provided with vertical Grouting Pipe 9 on horizontal grouting pipe 8; After above program construction finishes, colligation raft foundation base plate two-way concrete slab 7 and top two-way concrete slab 11, and first concreting 12; After treating that concrete shrinkage is accomplished basically, the after-pouring concrete 6 again.When finding that the constuction joint place leaks, carry out pressure grouting through vertical Grouting Pipe 9, horizontal grouting pipe 8, reach the purpose of leak stopping.
Change rubber fastening band into be arranged on steel concrete bottom by being arranged on the centre position of reinforced concrete construction seam place, saved the fixedly operation of the reinforcing bar fixed mount of waterstop of welding along short transverse, simple, convenient, practice thrift man-hour, reduce cost; Simultaneously, owing to increased Grouting Pipe, after the concreting of whole raft foundation was accomplished, because other reasons causes the constuction joint place to leak, the method for slip casting can easy to doly be carried out leak stopping in taking to manage, and reaches the purpose that control combines.
