Type embedded footing on piles, low capped pile foundation plinth.
Background technology
Along with the fast development of China's economy, the building trade of China obtains significant progress.The height of building structure
It is continuously increased with complexity.With the continuous improvement of the depth-width ratio of structure, building foundation is by horizontal loading and vertical load
Also more serious, the building foundation failure thereby resulted in personnel's wound caused by is responded with the sidesway and sedimentation of lower generation
Die and property loss problem protrusion also more, thereby, it is ensured that structural safety, stable operation have highly important meaning
Justice.Basis is the supporting member that construction bottom is contacted with ground, and its effect is that the load on building top is transmitted to ground, is room
Room, bridge, the important component of harbour and other structures.Building structure basis is transferred the load in ground no matter
Which is partly gone wrong or destroyed for ground or basis, and serious influence will be all caused to top-out structure or even is caused
Major accident.Due to foundation condition complexity and soil physico-mechanical properties particularity, the research of people so far to it
Also in exploration.Lot of examples shows that building foundation failure can cause serious consequence, and such as 2009, one of Shanghai completed
The non-delivery high building used of work integrally covers, and its main cause of collapsing is that design is unreasonable, and basic resistance to capsizing is poor.Basis
The selection of pattern is one of influence engineering overall cost principal element again, and the selection of foundation pattern should combine each section of landform, the hydrology
Geological condition, execution conditions and structure type etc. are determined, and should as much as possible be dropped on the premise of code or specification is met
Low construction costs.
For soft clay area building structure basis, unavoidably to pass through the situation in the weak location of some geology, it is conventional
Way is that, using commbined foundations and large-section in-situ concrete pile basis, but commbined foundations excavated volume is big, reinforcement foundation and concrete amount
Larger, foundation cost is high;And bored concrete pile single-pile foundation, because of requirement for bearing capacity, often diameter and the long all larger and anti-overturning of stake
Can be poor.For current situation, in the urgent need to proposing more rational foundation pattern, to reduce difficulty of construction and quantities, subtract
Few destruction to natural environment, and then reduce construction costs.This patent proposes combined embedded footing on piles, low capped pile foundation plinth, this new
Base form, can preferably solve the problem of conventional base is present.
