Description
Technical field
The invention belongs to the realm of building construction, relate to water conservancy project structure, especially a kind of method for blocking of water conservancy project structure tie rod hole and device.
Background technology
Large-scale hydraulic structure mostly are half buried structure, and outer bay wall face, without finishing, is faced concrete surface, and this structure requires higher to Surface Quality of Concrete.After form removable, concrete basin leaving part Screw arbor with nut at both-ends hole, there is risk of leakage in these Screw arbor with nut at both-ends holes, therefore must carry out shutoff when constructing.
In traditional construction, Screw arbor with nut at both-ends hole cannot be shaped location, and often pollutes the body of wall of hole periphery in the process of shutoff, thus affects shutoff quality and appearance effect.There is the problem that the surperficial plugging effect of pull bar hole is poor in above-mentioned construction method, have a strong impact on structure presentation quality, requirement real in the outer light of concrete cannot be reached.
Through retrieval, find one section of patent document relevant to present patent application: the rapid plugging method of concrete structure outer screw hole and structure, notification number (CN103790382A), the method be the concreting of shear wall complete and by wall form remove after, in External Wall screw hole, outer both sides adopt mechanical hole reaming, and the pvc pipe of reaming place is removed, foreign material rubbish in cleaning eye, and in screw hole, outer both sides place water is moistening, toward screw rod hole, foamed glue is squeezed into inside screw hole, when the foamed glue of injection screw rod hole reaches outside screw hole, the shutoff of dry waterproofing mortar is used immediately outside screw hole, continue to squeeze into foamed glue until fill, to in screw hole, outside dry waterproofing mortar shutoff, finally brushing polymer cement-based waterproof film is in screw hole outside.
Contrasted by technical characteristic, the screw hole in method for blocking disclosed in above-mentioned document adopts the mode of mechanical hole reaming, and its construction is loaded down with trivial details, reduces efficiency of construction and improves cost.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of method for blocking and device of water conservancy project structure tie rod hole, the method construction is simple, effectively improves shutoff quality and the appearance effect of tie rod hole.
The solution of the present invention is achieved in that
A method for blocking for water conservancy project structure tie rod hole, comprises the steps:
Step one, before model sheetinstallat, tapered steel is blocked up the both ends that coaxial specular is installed on Screw arbor with nut at both-ends, and the stifled miner diameter end of two tapered steel is arranged in opposite directions, then assembled formwork, vertical for template note is covered and is supported on the lateral surface that tapered steel blocks up bigger diameter end, then pass through screw lock;
Step 2, between template concreting pool wall, stripping and Screw arbor with nut at both-ends after building, inner hexagon spanner is inserted tapered steel stifled in hexagonal counterbore, rotating inner hex wrench takes out tapered steel and blocks up, and by stifled for tapered steel clean out to retain use next time; After the stifled taking-up of tapered steel, pool wall two sides specular is shaped with the pull bar hole of shape and pyramidal structure of the same size;
Step 3, configuration plasticity low water content shutoff mortar, inserted by the mortar prepared in the pull bar hole of pyramidal structure, mortar must fill up, tamp;
Step 4, use capping tools by mortar compacting, floating, specifically doing method of operating is: the handle end rotating capping tools, the disk end of this capping tools together rotates thereupon, the floating mortar surface limit extruding in limit mortar, mortar is filled up completely, tamps pull bar hole, this mortar surface is embedded in body of wall inboard;
Step 5: watering maintenance.
And the mortar in described step 3 is made up of cement, medium sand, water and lithopone, its ratio is 230-260:1200-1300:280-300:50-100 (kg/m
3), by four mix after and get final product.
And described mortar is 240:1221:290:50-100 (kg/m by the ratio of cement, medium sand, water and lithopone
3).
And the mortar surface in described step 4 is inlaid in the inboard 1mm place of body of wall.
A kind of plugging device of water conservancy project structure tie rod hole, comprise tapered steel to block up and capping tools, the profile that described tapered steel blocks up is frustum type structure, and this tapered steel blocks up the centre bore being coaxially shaped with and holding Screw arbor with nut at both-ends, and the bigger diameter end that this tapered steel blocks up coaxially is shaped with interior hexagonal counterbore;
Described capping tools comprises disk and the handle of steel plate material, and this handle and disk are linked together by stock, and the diameter of described disk is less than the diameter that described frustum steel blocks up bigger diameter end.
And described disk is steel plate material.
Advantage of the present invention and good effect are:
1, in the present invention by using the tapered steel of new structure to block up, make to build shaping after concrete-pool-wall on the pull bar void shape that is shaped with and in the same size; Pull bar hole accurately can be located by using special capping tools and fill up, compacting, floating, solve in traditional handicraft exist tie rod hole sizing location difficult, pollute tie rod hole periphery body of wall and the problem such as shutoff profile is uncontrollable, achieve the object that pull bar holes blocking is attractive in appearance, shape size is consistent.
2, the mortar prepared in the present invention uses lithopone to replace white cement to mix colours, and solves the impact of white cement further hydration on color, ensures that pool wall appearance luster is consistent, improves pool wall overall appearance quality.
3, construction method of the present invention is simple, efficiency of construction is high, cost is low, easily grasp, ensure that the mortar of shutoff pull bar hole fills up, tamps and surfacing, ensure that shutoff quality and the appearance effect of pull bar hole, promote larger to this type of engineering construction quality, applied widely, there is the value of wide popularization and application.
