Abstract

The invention discloses a kind of booster stations building foundation construction method, include line setting, earth excavation, the steps such as reinforcing bar, formwork concreting are installed.Construction method of the present invention is reasonable in design, after the completion of construction, and booster stations building overall structure is stable, and service life is long.

Description

A kind of booster stations building foundation construction method
Technical field
The present invention relates to architecture construction field, specifically a kind of booster stations building foundation construction method.
Background technology
Arrived it is well known that the Chinese government makes promise in Copenhagen climate change conference in 2009 to international community The year two thousand twenty unit GDP CO2 emissions declined 40%~50% than 2005, and non-fossil energy will meet this country 15% energy demand, this development scale and progress to the following wind-powered electricity generation of China etc. is proposed unprecedented expectation, accelerates wind energy money The utilization in source with exploitation by as the important measure that the strategy of sustainable development is realized in China's considerably long one period, to the year two thousand twenty China's wind-powered electricity generation installation reaches 2.3 hundred million KW;Big good development environment and opportunity are provided for our Wind Power Developments.
In the construction of wind power plant, in order to reduce line current so as to reducing electric loss of energy, set up and rise in wind power plant Pressure has been stood into an essential construction procedure.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of booster stations building foundation construction method, it is ensured that after construction Booster station structure is stable, and service life is long,
The technical scheme is that:
A kind of booster stations building foundation construction method, has specifically included following steps:
(1), line setting:Survey crew is according to plant area's construction control network, and survey sets out production complex building control axis in length and breadth, is used in combination Red paint triangle, which is marked in, to be held on water coagulation soil padding;Workmen releases frame foundation, grade beam according to control axis in length and breadth Frame line and column cap joint bar frame line, the construction of muscle formwork erection is pricked for frame foundation and coupling beam;
(2), earth excavation:150mm thick soil stratums are reserved during mechanical equivalent of light excavation, at foundation platform design mark is excavated to by artificial progress Height, remaining soil for all reserving 200mm or so is removed to bed course bottom absolute altitude by excavated by manual work, and excavation of foundation pit carries out ground after finishing and tested Groove;Stake head handling is carried out after test slot of foundation and bed course is poured;
(3), install reinforcing bar:The reinforcing bar of first installation foundation cushion cap bottom plate, then inserts cushion cap bottom, then install by foundation columns reinforcing bar Cushion cap beam steel, the colligation for finally carrying out reinforcing bar is fixed;
(4), formwork concreting:After the completion of template is set up, concrete uses placement layer by layer, and vibration is shaken using the plug-in types of φ 50 Dynamic rod vibrates, often pour one layer vibrate one time, every two layers between vibrating head should insert 10cm in next layer concrete, while shaking When smashing layer concrete, to be carried out before the initial set of next layer concrete, the order of vibrating of concrete uses " determinant ", shakes a little Evenly distributed, each displacement is not more than 1.5 times of vibrating head operating radius R, " fast to insert slow using to accomplish during vibrating head Pull out ", prevent facing concrete from occurring layering, isolation, and the phenomenons such as cavity are caused during vibrating head extraction, vibrating time is 20- 30s, is in level depending on concrete surface, no longer significantly sinks, bubble, surface bleeding no longer occur and be defined;Concreting is finished Afterwards, struck off in time with floating rule, and receipts face is smeared with wood, smear twice of plucking again before concrete final set with wood.
Described concrete vibrating method using it is vertical vibrate or it is oblique vibrate, vertically vibrate i.e. vibrating head and concrete table Face is vertical, it is oblique vibrate i.e. vibrating head with concrete surface into 40 ° -45 °.
Described concreting carries out humiture maintenance after finishing, and curing time is at least 7 days, after having conserved, and removes Template.
Advantages of the present invention:
Construction method of the present invention is reasonable in design, after the completion of construction, and booster stations building overall structure is stable, and service life is long.
Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation Example only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common The every other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model that the present invention is protected Enclose.
A kind of booster stations building foundation construction method, has specifically included following steps:
(1), line setting:Survey crew is according to plant area's construction control network, and survey sets out production complex building control axis in length and breadth, is used in combination Red paint triangle, which is marked in, to be held on water coagulation soil padding;Workmen releases frame foundation, grade beam according to control axis in length and breadth Frame line and column cap joint bar frame line, the construction of muscle formwork erection is pricked for frame foundation and coupling beam;
(2), earth excavation:150mm thick soil stratums are reserved during mechanical equivalent of light excavation, at foundation platform design mark is excavated to by artificial progress Height, remaining soil for all reserving 200mm or so is removed to bed course bottom absolute altitude by excavated by manual work, and excavation of foundation pit carries out ground after finishing and tested Groove;Stake head handling is carried out after test slot of foundation and bed course is poured;
(3), install reinforcing bar:The reinforcing bar of first installation foundation cushion cap bottom plate, then inserts cushion cap bottom, then install by foundation columns reinforcing bar Cushion cap beam steel, the colligation for finally carrying out reinforcing bar is fixed;
(4), formwork concreting:After the completion of template is set up, concrete uses placement layer by layer, and vibration is shaken using the plug-in types of φ 50 Dynamic rod vibrates, often pour one layer vibrate one time, every two layers between vibrating head should insert 10cm in next layer concrete, while shaking When smashing layer concrete, to be carried out before the initial set of next layer concrete, the order of vibrating of concrete uses " determinant ", shakes a little Evenly distributed, each displacement is not more than 1.5 times of vibrating head operating radius R, " fast to insert slow using to accomplish during vibrating head Pull out ", prevent facing concrete from occurring layering, isolation, and the phenomenons such as cavity are caused during vibrating head extraction, vibrating time is 20- 30s, is in level depending on concrete surface, no longer significantly sinks, bubble, surface bleeding no longer occur and be defined;Concreting is finished Afterwards, struck off in time with floating rule, and receipts face is smeared with wood, smear twice of plucking again before concrete final set with wood;Concrete vibrating method is adopted With it is vertical vibrate or it is oblique vibrate, the i.e. vibrating head that vertically vibrates is vertical with concrete surface, oblique i.e. vibrating head and the coagulation of vibrating Native surface is into 40 ° -45 °;
