Description
Technical field
The present invention relates to a kind of engineering construction field, the production technology of espespecially a kind of basement cushion cap and its safe construction side
Method.
Background technique
With urbanization be transformed in building engineering construction increasingly extensity, the mankind to the utilization rate of land resource with
Urbanization process is accelerated and is increasingly improved, demand of the mankind to the underground space and more more and more intense, the basement suspended deck structure of dependence
As the important component in building engineering, people the construction quality of the structure is also more come with cost requirement it is also high,
But various special geologic conditions are also more and more in existing architectural engineering, caused the quality, efficiency, engineering of bearing platform construction therewith
Cost and difficulty of construction climb up and up, and especially the project cost under mal-condition and difficulty of construction are significantly promoted,
It is basement cushion cap engineering construction under mal-condition that difficulty of construction is higher；If do not had using traditional Construction Technology of Rider
There are any technical breakthrough and innovation, it is likely that building engineering construction cost is caused to break through cost, and bearing platform construction expense
Also there is very big specific gravity in entire building engineering cost, once cushion cap goes wrong and may jeopardize whole house and cause not
Repairable loss.
In Delta of Pearl River, the Delta of the Pearl River belongs to alluvial plain landforms, and rich groundwater, mud are thicker,
In the building of the landforms, basement cushion cap is in thick mud layer, and cutting depth is big and mobility is big, and bearing platform construction process
Belong to deep basal pit, height difference is more than 6m, and pattern foundation pit supporting structure stress condition and stability are difficult to determine, therefore want in basement bearing platform construction
Construction quality is protected, task is arduous in the extreme；It is touched if directlying adopt conventional method and excavating branch, template can not fix, and cushion cap quality is difficult
To be controlled, the excavated volume of traditional cushion cap excavation construction in thick mud layer is much larger than in preformed reinforced concrete shuttering cushion cap
Excavated volume, if with to pass wooden model, brick mold is considered as template construction, cannot achieve economic benefit and most rationalize, a side
Face, traditional brick fetal membrane construction, since cushion cap is in thick mud layer, the construction of traditional brick fetal membrane is slower, and this engineering cushion cap is more, always
Body construction is inefficient and the basement duration is tight, and on the other hand, traditional wooden film construction party, tradition wood film construction cost is higher,
And this engineering cushion cap is more, overall construction cost is higher, therefore both schemes are not paid attention to.How in basement cushion cap
While accelerating speed of application in construction, guarantee safety, quality, and applying for basement cushion cap is completed in cost-saved situation
Work is to still need to discuss at present to solve the problems, such as.
