Abstract
The present invention relates to a kind of construction methods of cast-in-place lattice steel concrete stiffness stake; construction including cement mixing pile; the production of lattice type steel angle cage skeleton; coarse aggregate concrete is filled as stake core by lattice type steel angle cage frame center, and coarse aggregate concrete merges to form cast-in-place lattice steel concrete stiffness stake with lattice type steel angle cage skeleton and cement mixing method.It is an advantage of the invention that quick construction, energy conservation and environmental protection is without squeezing soil, and bearing capacity is higher, and globality is strong, low cost.
Description
Technical field
The invention belongs to base pit engineering technical fields, and in particular to a kind of construction party of cast-in-place lattice steel concrete stiffness stake
Method can be used for the construction of building pile foundation engineering and Foundation Pit Support Engineering.This technique can effectively avoid the soil compaction of traditional prefabricated tubular pile
Influence to surrounding enviroment;Compared to the mud contamination of conventional borehole stake, this technique is without mud emission, safety and environmental protection.
Background technique
Currently used engineering pile is divided into prefabricated pile and bored concrete pile.
Cast-in-situ bored pile generally uses mud off pore-forming, under water placing concrete technology, is easy to appear broken pile, contracting
Neck, concrete disintegration and that bottom hole loosened soil or sediment are blocked up and other issues, there are speed of applications is slow, cost is high, mud contamination ring
The disadvantages of border.
Precast reinforced concrete piles are a kind of domestic most commonly used pile-type, the shapes such as, round rectangular using section.It is prefabricated
Stake pile sinking mode have hammering method, vibratory drilling method and static pressure method, have many advantages, such as reliable in quality, speed of application fastly, low cost.But
It belongs to Squeezing Soil Pile, and when construction easily causes surrounding land upheaval, can also cause that adjacent stake is floated in place sometimes, during the pile driving process
Extruding is generated to the soil body, neighboring buildings, road, underground utilities etc. is influenced, easily causes dispute, in order to avoid driving piles to ring around
The influence in border needs to increase additional protection expense, so its use is limited by many conditions.
Summary of the invention
According to the deficiencies of the prior art described above, It is an object of the present invention to provide a kind of cast-in-place lattice steel concrete stiffnesses
Stake, by the cement mixing pile constructed, being pressed into lattice type steel angle cage skeleton, the filling of lattice type steel angle cage frame center is thick
Skeletal grain concrete merges to form cast-in-place lattice with lattice type steel angle cage skeleton and cement mixing method as stake core, coarse aggregate concrete
Structure formula steel concrete stiffness stake, gives full play to the compression strength of concrete, and the tensile property and soil cement of lattice type steel angle cage skeleton are stirred
Mix the sealing performance of stake.
The object of the invention realization is completed by following technical scheme:
A kind of cast-in-place lattice steel concrete stiffness stake, it is characterised in that the cast-in-place lattice steel concrete stiffness stake includes including water
The construction of mud mixing pile, the production of lattice type steel angle cage skeleton, lattice type steel angle cage frame center fill coarse aggregate concrete and make
For stake core, coarse aggregate concrete merges to form cast-in-place lattice steel concrete stiffness with lattice type steel angle cage skeleton and cement mixing method
Stake.
The cast-in-place lattice steel concrete stiffness stake, it is characterised in that the production of the lattice type steel angle cage skeleton is by 4
The square that root angle steel and steel plate are welded from top to bottom is uniformly arranged horizontal steel plate between every 2 angle steel, at a certain distance
Arrangement is welded.
The cast-in-place lattice steel concrete stiffness stake, it is characterised in that the size of the lattice type steel angle cage skeleton can
Freely to adjust spacing according to angle steel and junction steel plate, field fabrication.
The cast-in-place lattice steel concrete stiffness stake, it is characterised in that the stake core filler is coarse aggregate concrete, broken
Stone grain diameter is 10~30mm.
The cast-in-place lattice steel concrete stiffness stake, it is characterised in that the cast-in-place lattice steel concrete stiffness stake is by first applying
Work cement mixing method is pressed into lattice type steel angle cage skeleton in mixing pile, injects coarse aggregate in lattice type steel angle cage skeleton
Concrete.
The cast-in-place lattice steel concrete stiffness stake, it is characterised in that the lattice type steel angle cage skeleton can be single-unit,
It is also possible to more piece to be spliced.
The invention has the advantages that
Compared to traditional prefabricated tubular pile, this technique effectively reduces soil compaction influence caused by surrounding enviroment.It is same meeting
In the case where bearing capacity, 20% or more is saved than tradition prefabricated tubular pile cost.
Compared with conventional borehole bored concrete pile, this technique is pollution-free to surrounding enviroment without mud emission.Lattice type steel angle cage bone
Frame field fabrication, skeleton size can adjust according to actual needs, and easy to make, securely and reliably, stability is strong.It is same meeting
In the case where equal bearing capacities, 15% or more is saved than conventional borehole bored concrete pile cost.
