Abstract
The invention discloses a manufacturing method and a structure of a post-poured strip of an underground building. After the construction of a basement pit baseplate cushion layer (1) finishes, a layer of waterproof coiled material (2) is laid on the basement pit baseplate cushion layer (1), then an externally-adhered waterstop (5) is pre-embedded on the waterproof coiled material (2) and the joint of main structure (3) to be made and the post-poured strip (4), and the main structure (3) is poured by adopting a conventional process; after the concrete of the main structure (3) has the age of six weeks, the concrete at the joint of the main structure (3) and the post-poured strip (4) is roughened, and then shrinkage-compensating concrete is used to pour to obtain the post-poured strip. The post-poured strip has the advantages of good water and seepage prevention performance, simple structure and convenience for construction. The post-poured strip is particularly suitable for the basement baseplates and side walls of the semi-underground power transforming and rectifying room in an electrolysis workshop when the geological condition of a foundation is good and the underground water level is high.
Description
Technical field
The present invention relates to the preparation method and the structure of ater-casting, a kind of underground structure, belong to building ater-casting manufacture technology field.
Background technology
Aluminium electroloysis belongs to metal smelt technology, and primary raw material is an alumina powder, produces aluminum solutions; The major impetus source is a direct current; It becomes 240kA to 500kA direct current directly to supply with electrolysis production after the power transformation rectification and uses from the 110kV alternating current of high-voltage fence, and China produces per year at 4 of the more employings of the electrolytic aluminium factory more than 100,000 tons and 4 above Rectification Power Factor outlets intervals at present; Building perimeter is many more than 60 meters, and often is semi-underground cell-type building.The equipment indoor because of rectification is charging equipment; And rectification chamber residing special critical role in whole electrolytic aluminium factory building; Be positioned at basement and when the higher unfavorable factor of underground water level exists, particularly surpassing 60 meters, when the basement melt pit need be provided with the ater-casting when the rectification chamber again when rectification chamber length; Because this ater-casting is the waterproof weak link, its water proof structure is handled and is seemed particularly important.And the waterproofing work of melt pit ater-casting, existing power transformation rectification chamber is together to two road waterproof, its waterproof ability a little less than, and the hidden danger of leaking is arranged.Therefore, the production method of ater-casting, existing underground structure still can not satisfy the needs of use.
Summary of the invention
The objective of the invention is: the preparation method and the structure of the stronger ater-casting, underground structure of a kind of simple in structure, easy construction and waterproof, seepage control ability are provided, to overcome the deficiency of prior art.
The present invention is achieved in that the preparation method of ater-casting, a kind of underground structure of the present invention; Be after the melt pit base plate cushion construction of basement finishes; On melt pit base plate bed course, completely spread one deck waterproof roll; Then on waterproof roll, at the agent structure of prepare making and the pre-buried external labeling type waterstop of seam crossing of ater-casting, and then water by common process and to outpour agent structure, reached for six weeks the age of concrete of treating agent structure after; Behind the concrete chisel hair with its seam crossing that combines with the ater-casting, adopt expansive concrete to build out the ater-casting again.
Above-mentioned waterproof roll is synthetic high polymer (polyvinyl chloride) waterproof roll, the thickness>=1.2mm of waterproof roll, and its hot strength is 2.0～4.5MPa, its elongation at break>=120%, its tearing strength is 0.8～0.2, its water absorption rate≤0.5%.
Above-mentioned external labeling type waterstop is the thick aluminium alloys contour plate section bar of 1.0mm～1.5mm.
The above-mentioned cement grade that expansive concrete adopted of building the ater-casting should be higher than more than the concrete cement label secondary of agent structure of its both sides.
The structure that is used for the ater-casting, a kind of underground structure of the inventive method does; Comprise melt pit base plate bed course, agent structure and ater-casting; Between melt pit base plate bed course and agent structure and ater-casting, be provided with one deck waterproof roll; And between agent structure and ater-casting and waterproof roll, also be provided with the external labeling type waterstop, and the external labeling type waterstop all covers in the seam crossing of agent structure and ater-casting.
The width of above-mentioned each external labeling type waterstop that the seam crossing of agent structure and ater-casting is all covered in is 150mm～250mm.
Owing to adopted technique scheme, the present invention compared with prior art has following characteristics:
1. between melt pit base plate bed course and agent structure and ater-casting, be provided with one deck waterproof roll; Waterproof roll is synthetic high polymer (polyvinyl chloride) waterproof roll; Can strengthen the waterproof ability of melt pit base plate bed course and agent structure effectively, improve the anti-of whole building structure greatly and leak and the percolation-proof performance.
2. the seam crossing in agent structure and ater-casting adopts the thick aluminium alloys press-formed plate material of 1.0mm～1.5mm as the external labeling type waterstop, can not only strengthen the mechanical strength of seam crossing, but also improve the waterproof penetrating power of seam crossing greatly.
3. adopt the cement grade of the expansive concrete build the ater-casting should be higher than more than the concrete cement label secondary of agent structure of its both sides, can improve the anti-deformation ability and the water resistance of ater-casting so effectively.
Therefore, the present invention compared with prior art, the present invention not only has the good advantage of waterproof, seepage control performance, but also has advantage simple in structure, easy construction.It is better that the present invention is particularly suitable for the ground geological conditions, uses on the basement bottom board of the semi-underground power transformation rectification chamber in the cell room when groundwater table is higher and the sidewall.
