Abstract
The invention provides a method of pouring and constructing the side wall of a hydraulic building, comprising the following steps: a, wet concrete is prepared, and the wet concrete is evenly stirred into water, sand and gravel according to the mixing ratio of 0.55:1:2.64:4.86 for later use; b, dry concrete is prepared without using water, and the dry concrete is evenly stirred into sand and gravel according to the mixing ratio of 1:2.64:4.86 for later use; c, if the surface of the side wall of the hydraulic building has water and bubbles during the pouring of the wet concrete, the already stirred dry concrete whose volume accounts for 10 percent of the volume of the whole pouring concrete is evenly scattered on the vibrated surface of the side wall, then the vibrated surface is continuously vibrated until the surface of the concrete poured on the vibrated surface has no water, and the wet concrete is vibrated in a vibrating bin, wherein if the surface of the side wall is subjected to water again, the procedures are repeated until the side wall of the hydraulic building is poured well. The method of pouring and constructing the side wall of the hydraulic building is easy with low difficulty and can make the outer appearance of the side wall of the hydraulic building smooth.
Description
Technical field
The present invention relates to a kind of technical method that reduces voids and pits in the building of small-sized hydraulic structure side wall, is a kind of pouring construction method of hydraulic structure side wall specifically.
Background technology
In the building of small-sized hydraulic structure side wall, often occur " voids and pits ", voids and pits appears, not only do not reach the bright and clean effect of concrete surface as mirror, if can not in time handle, in the water process of being expert at, because washing away and corroding of current through long-play, also will damage building.In order to make concrete surface not produce voids and pits, adopted now the way of some eliminations in the engineering construction, traditional method is to use air entraining agent, reduces the concrete stickiness, control green concrete workability, add method such as defoamer when mixing the system concrete.In small hydraulic project is built, this class methods operation is many, to determining that the optimal vibration molding time is difficult to hold, concrete mix is difficult to hold, adopt material is good, finish is high template, select high-quality release agent cost height for use, difficulty of construction is big, all not too suitable, only can increase engineering quantity and cost.
Summary of the invention
The present invention is exactly the deficiency that exists at prior art, and a kind of pouring construction method of building side wall being built a kind of hydraulic structure side wall that can reduce voids and pits in the small hydraulic project construction is provided.
Technical problem of the present invention adopts following technical proposals to solve:
A, preparation water-bearing concreae
Press water: cement: sand: gravel=0.55: 1: 2.62: 4.86 match ratio uniform mixing water-bearing concreae is stand-by;
B, preparation dry concrete
Do not add water, press cement: sand: the even dry concrete of match ratio mix of gravel=1: 2.62: 4.86 is stand-by;
C, build
Build in the process at water-bearing concreae, when moisture content and bubble appear in surface layer, the dry concrete that accounts for total concreting volume 1/10 that mixes and stirs evenly is sprinkling upon on the surface layer after vibrating, proceed then to vibrate, process is vibrated the water-bearing concreae warehouse entry, when moisture content occurring once more after vibrating and making the concreting top layer not have ponding again, repeat this operation, finish until the work of building.
Job practices of the present invention is easy to operate, and difficulty of construction is little, and can make the hydraulic structure side wall reach bright and clean appearance effect as mirror.
The specific embodiment
Below in conjunction with embodiment the present invention is further elaborated:
Embodiment 1
1, preparation dry concrete
It is even to get 50 kilograms of cement, 131 kilograms of sands and 243 kilograms of gravel mixs, and it is stand-by to make 424 kilograms of dry concretes;
2, preparation water-bearing concreae
Get 280 kilograms of cement, 736 kilograms of sands and 1381 kilograms of gravels, slowly be blended into while stirring with 150 kg of water, it is stand-by to mix and stir into 2547 kilograms of water-bearing concreaes;
3, build 2500 kilograms of water-bearing concreaes, when moisture content and bubble appear in surface layer, getting the dry concrete that mixes and stirs is sprinkling upon on the surface layer after vibrating equably, proceed then to vibrate, after the concreting top layer does not have ponding, again the water-bearing concreae warehouse entry is vibrated, when moisture content occurring once more, repeat this operation, finish until the work of building.The amount of being sprinkled into always of dry concrete is 250 kilograms.
Claims (1)
1. the pouring construction method of a hydraulic structure side wall is characterized in that being undertaken by following step:
A, preparation dry concrete
Do not add water, press cement: sand: the even dry concrete of mixing ratio by weight mix of gravel=1: 2.62: 4.86 is stand-by;
B, preparation water-bearing concreae
Press water: cement: sand: gravel=0.55: 1: 2.62: 4.86 mixing ratio by weight uniform mixing water-bearing concreae is stand-by;
C, build
Build in the process at water-bearing concreae, when moisture content and bubble appear in surface layer, the dry concrete that accounts for total concreting weight 1/10 that mixes and stirs evenly is sprinkling upon on the surface layer after vibrating, proceed then to vibrate, process is vibrated the water-bearing concreae warehouse entry, when moisture content occurring once more after vibrating and making the concreting top layer not have ponding again, repeat this operation, finish until the work of building.
