Abstract
The invention relates to a prefabricated ground. The prefabricated ground comprises a plurality of pile foundation assemblies arranged in a foundation and distributed in an array manner, main beams each erected between two corresponding adjacent pile foundation assemblies and a bottom plate supported on the main beams. Each pile foundation assembly comprises a preformed pile and a bearing table fixedly arranged at the upper end of the preformed pile. One aim of the prefabricated ground is to provide the prefabricated ground capable of increasing the engineering construction speed and quality. The prefabricated ground has the beneficial effects that the site construction speed of the prefabricated ground is high and is one few hundredth of the time needed for a conventional foundation treatment scheme, and therefore the investment recovery period is shortened, the overall cost input is reduced, and remarkable economic benefits are achieved; and deformation of the prefabricated ground in the using period is remarkably reduced relative to that of the conventional foundation treatment scheme, and the maintenance cost of house buildings in the using period can be reduced.
Description
Technical field
The present invention relates to the realm of building construction, particularly a kind of prefabricated assembled ground and construction method.
Background technology
It is located at coastal soft clay area more in the economically developed city of China, generally requires to carry out when Large scale construction is carried out soft
Native basement process.With the continuous development of China's economy, construction scale expanding day, engineering construction is also carried to Soft Ground
Higher requirement is gone out.Engineering construction is carried out on soft soil foundation, if do not taken effective reinforcement measure, ground to slide
Shifting, cracking or depression etc.；If basement process is improper, foundation instability is easily caused so that building occurs excessive sedimentation or inequality
Even sedimentation, affects the safety of building.
At present conventional method for processing foundation has：Surface layer logos, heavy-tamping method, pre-pressure drainage consolidation method, rubble (sand pile)
Stake, sand mat of subgrade, pile foundation method, soil replacement method, grouting method and reinforcement method etc..
Soft soil foundation has the engineering characteristics such as void ratio is big, water content is more, water penetration is little, shearing strength is low, compressibility is big,
Foundation bearing capacity can not meet the needs of engineering construction substantially.Though existing method for processing foundation can solve ground to a certain extent
Base Carrying Capacity, but generally require relatively long construction period.The weak soil thickness in many areas is larger, by basement process
Cost is limited, and often settlement after construction is larger, have impact on normally using after completion of works, in some instances it may even be possible to cause engineering to fail.
The content of the invention
An object of the present invention is to provide a kind of prefabricated assembled ground that can lift engineering construction speed and quality.
The second object of the present invention is to provide a kind of speed of application soon, and holistic cost puts into low prefabricated assembled ground
Construction method.
The purpose of the present invention is achieved through the following technical solutions：
A kind of prefabricated assembled ground, it includes some inserting in ground and the pile foundation component in array distribution, being erected at
Girder between two adjacent pile foundation components and the base plate being supported on girder；The pile foundation component includes prefabricated pile and fixed
In the cushion cap of prefabricated pile upper end.
A kind of construction method on prefabricated assembled ground, it is comprised the following steps：
Each prefabricated pile is squeezed in ground, is in array distribution between prefabricated pile；
In prefabricated pile upper end fixed bearing platform；
By main beam supporting on two adjacent cushion caps；
Base plate is laid on girder.
For than prior art, it is an advantage of the current invention that：
1. the site operation speed on prefabricated assembled ground is fast, is several percentages the time required to conventional Ground Treatment Schemes
One of, return period is invested so as to shorten, holistic cost input is reduced, with obvious economic benefit.
2. deformation during use more conventional Ground Treatment Schemes in prefabricated assembled ground are obviously reduced, it is possible to reduce room
Build the maintenance cost in validity period in room.
3. prefabricated assembled ground is in built on stilts state, it is to avoid contact of the armored concrete ground with the soil body, can be with
Reduce bottom is affected using the moisture in space, and improvement uses function；Additionally, the prefabricated assembled ground of built on stilts state, can subtract
The backfill quantity in few place, with good economic benefit.
4. stretching the scheme shelved in being connected by of girder and cushion cap can significantly simplify the construction of prefabricated beam end shearing resistance,
Save node cost.
