Description
Technical field
The present invention relates to construction, pile foundation engineering technique more particularly to pile foundation abolish with construction environment control problem,
Specifically a kind of noiseless broken pile device and broken pile method.
Background technique
Pile foundation is all kinds of most common foundation patterns of engineering buildings or structures, with bearing capacity is high, stability is good, place
The advantages that adaptable.The important function for playing support superstructure is driven underground in pile foundation, and superstructure then stands on pile foundation
On the absolute altitude of top surface.With high-rise, the construction of super high-rise building and urban underground space exploitation, the designed elevation of pile foundation is often
At several meters even more than ten meters of below ground.And construction project construction when, pile foundation often squeezes into below ground in advance, then into
Row excavation of foundation pit just needs to break pile foundation that is extra, being higher by designed elevation when excavation arrives Pile Foundations Design absolute altitude.Tradition
Broken pile technology be using dedicated broken pile machine, under vibratory impulse, by pile body concrete disintegrating, concrete is then truncated in broken pile machine
Internal reinforcing bar, the pile body for being higher by designed elevation is removed.This broken pile method often generates great vibration noise and building
Disintegrating slag, and inefficiency pollute environment.
Soundless cracking agent (referred to as: SCA) is that a kind of Novel static developed the external seventies is crushed reagent, the eighties
Since, Research Institute of Building Materials Industry, State Bureau of Building Materials Industry, China and some enterprises research and develop success in succession, have commercially produced
Using.SCA is tuned into slurry with water, is poured in the drilling of rock or concrete, can generate powerful expansion under room temperature effect
Power has the advantages that be perfectly safe, is pollution-free, vibrationless so that it is broken so that concrete and rock is generated cracking.Although noiseless broken
Broken dose is widely used for the fields such as dismantling concrete building and exploitation cutting marble, granite, but does not have one kind also so far
The special device and its application case that noiseless broken pile is carried out using soundless cracking agent.
Summary of the invention
Goal of the invention: for the broken pile problem of pile foundation after excavation of foundation pit, the present invention provides a kind of noiseless broken pile device and broken

Validity；
Step4: checking, rotatably, and vertical liquid injection pipe is examined successively in the validity and inner catheter for checking diverter
With the binding fixing of transverse annular conduit；
Step5: decentralization steel reinforcement cage is transferred to noiseless broken pile device in drilling in company with steel reinforcement cage, together after decentralization
The upper end liquid inlet for blocking vertical liquid injection pipe avoids falling into sundries when construction and causing line clogging；
Step6: note concrete grout injects concrete grout into drilling, forms pile body；
Step7: injection soundless cracking agent, when absolute altitude is truncated in excavation of foundation pit to pile foundation, releases vertical according to construction speed
The closure of liquid injection pipe upper end liquid inlet injects soundless cracking agent into vertical liquid injection pipe by high-pressure pump, passes through unidirectional spray hole
It flows into concrete；
Step8: broken pile, after concrete spalling failure, will the peripheral reinforcing bar truncation in part, then with mechanical external force by upper section
Pile body is integrally abolished.
The utility model has the advantages that noiseless broken pile device provided by the invention and broken pile method, solve long-standing broken pile construction
Strong noise, inefficiencies problem；Soundless cracking agent is injected inside concrete by way of pre-buried pipeline by the method for the present invention, is reached
To the purpose of reduction concrete strength, the environmental protection of whole operation processing efficient and without special broken pile machinery, installation method is simple, fits
