Description
Technical field
The present invention relates to building field, and in particular to a kind of PHC pile piles are made the connector of support system lattice column and its applied
Work method, is directed to use with the connector and substitutes PHC pile pile portion segments causing bracing members in the segment zones, concrete branch
Support and structures agent structure are securely and reliably passed through, so as to fulfill the branch for substituting cast-in-situ bored pile+steel column in traditional construction
Support body system.Base pit engineering is built in all kinds of municipal, rooms that can be applied in current building field.
Background technology
As the quick increase of the urban residence size of population, land resource are increasingly deficient, people gradually put into notice
The development and utilization of the underground space, various constructions of structures extend to underground one after another, and incident is exactly deep foundation pit engineering
Increase.The fender body form that can be taken for large deep foundation pit engineering is varied, there is the stake of SMW engineering methods, drill-pouring
Stake, diaphram wall etc., supporting form are ever-changing, have concrete support, steel pipe support, type steel support etc., but wherein rise
The key component stablized to retaining design --- the form of lattice column still uses the form of cast-in-situ bored pile+steel column substantially.
Major defect is：
(1) environmental pollution is big：Since lattice column bottom uses cast-in-situ bored pile form, and in bored pile construction process
In will produce largely discarded mud, have a great influence to surrounding enviroment.
(2) site condition is more：Either the steel reinforcement cage of bored concrete pile or steel column are required to be processed assembly at the scene,
Therefore, it is necessary to prepare corresponding processing site, hoisting transportation equipment etc..
(3) construction speed is slow：For PHC pile piles, the pile-forming speed of cast-in-situ bored pile is only the 1/20 of prefabricated pile,
And with stake footpath, the long increase of stake, effect gap expands all the more.
(4) quality control is difficult：Drilling pouring pile hole aperture, verticality, sediment thickness, concreting and steel reinforcement cage
And the quality critical point such as steel column scene processing installation is more, control difficulty is big.
(5) construction technology defect：Main reinforcement in concrete support and structure, which runs into steel column, to pass through, and cause reinforcing bar to break
Open, even if still suffering from hidden danger using reinforcement measure.In addition, any excess concrete inside steel column is invaded when cast-in-place pile concrete pours
Artificial chisel is needed to remove, it is time consuming, and handle and bad easily trigger structural leakage.
(6) complicated construction technique：Mixed in early period pile foundation construction comprising drilling, borehole cleaning, steel reinforcement cage and steel upright post hoisting, under water
Solidifying soil pours, later stage earth excavation and the multiple working procedures such as the structure fabrication stage cuts comprising pile crown scum silica frost, bar straightening anchors, into
And site operation organization and administration program is caused to become relatively complicated.
(7) operating expenses is high：Cast-in-situ bored pile and steel column construction cost are far above other kinds of stake, meanwhile, on
State pile-type and be only purely by way of lattice column use, the negligible amounts applied in actual Foundation Pit Support Engineering so that unit price is further
Improve, operating expenses increase.
