Abstract
A method to control the influences of piling to the surrounding environment comprises the noise control, the vibration control, and the displacement control. The method is characterized in that a hydraulic pile hammer is used and a muffler is arranged on the surface of the hammer for the noise control; the piling energy is controlled, the smaller pile hammer energy is set for piling in the shallow stratum and the pile hammer energy is increased as the depth of piling is increased for the vibration control; an underground continuous wall is arranged and the daily piling quantity is controlled for the displacement control. The invention can effectively reduce the influences to the surrounding environment during the construction, and effectively reduce the noise pollution, the vibration pollution and the soil displacement.
Description
Technical field
The present invention relates to technical field of buildings, concrete is the control method of a kind of engineering piling to surrounding environment influence.
Background technology
The city piling construction, the construction infection scope is big, to around the influence of environment mainly comprise noise pollution, vibration pollution, land movement.Noise pollution influences the townsfolk and has a rest; For near the shielded building the engineering, vibration isolation is strict, can not produce vibration pollution; Near the engineering building is subjected to effect of project can produce displacement.
Given this, control piling process, with reduce engineering to the influence of surrounding environment show very necessary.
Summary of the invention
Technical problem to be solved by this invention is to provide the control method of a kind of engineering piling to surrounding environment influence, to reduce the influence of engineering piling to surrounding environment.
Technical scheme to be solved by this invention can be achieved through the following technical solutions:
A kind of engineering piling is to the control method of surrounding environment influence, comprises that noise control, vibration isolation, displacement control three parts, it is characterized in that, adopts hydraulic pile hammer in the noise control, and in the appearance of hydraulic hammer noise damper is installed; Control driving energy in the vibration isolation, shallow-layer piling is provided with less pile monkey energy, increases with driving depth, increases the pile monkey energy; Underground slider is set and controls the quantity of driving piles every day in the displacement control.
The present invention can effectively reduce in the work progress the influence of surrounding environment, has reduced noise pollution, vibration pollution, land movement effectively.
The specific embodiment
Describe the present invention in detail below in conjunction with the specific embodiment:
1 noise control
The noise of hydraulic impact hammer is less relatively, and this engineering is selected SC-150 type hydraulic pile hammer for use.
SC-150 hydraulic hammer hypomere points of articulation appearance is installed noise damper, and the sealing noise source reduces noise pollution from the source.
The piling time is controlled at 7:00 in morning ~ evening 21:00, sooner or later period and period in the late into the night only pile extension do not drive piles.
In the work progress, use noise decibel monitor that the noise that piling produces is carried out tracking and monitoring; Simultaneously, environmental noise is monitored.The reason that the analysis-by-synthesis noise produces is fed back in construction guiding construction.
2 vibration isolations
The control driving energy.During shallow-layer piling, the pile monkey energy settings is less, and the vibration surface wave energy of generation is also little; Stake is buried dark, and the pile monkey energy settings is bigger, and the energy dissipation face is also big, and is less relatively along the entity wave energy of a direction.So along with the increase of driving depth, for the injection and the bearing capacity needs of stake, hammering energy increases gradually, the diffusingsurface increase of energy is faster, helps reducing the vibration effect to the same building thing.
The degree of depth of open caisson has been cut off the surface wave that piling causes, makes the piling vibration energy account for 2/3rds surface wave and is blocked.
The degree of depth of ground-connecting-wall has been cut off the surface wave that piling causes, makes the piling vibration energy account for 2/3rds surface wave and is further stopped.
Deepen with the high-pressure rotary-spray body along the Suzhou River side at ground-connecting-wall, the entity ripple that the vibration of cut-out stake point produces makes compressional wave and shearing wave partly be reflected, partly be absorbed.
Project organization is optimized: pile foundation changes Φ 1000mm bored pile into.Obviously, Bored Pile Construction can not produce vibration to the soil body.
3 displacements control
Before south gate pier and the northern gate pier pile foundation construction, do diaphragm wall in two sides respectively, diaphragm wall is double-deck lattice structure, wall thickness 1000mm.Ground-connecting-wall is set plays the effect that face of land vibration wave transmits that cuts off.
Control the piling quantity of every day, one day pile sinking of southern gate pier Construction of Engineering Pile is controlled within 2, makes the soil body have the long time to discharge underground super interstitial hydraulic pressure, reduces the land movement amount.During the gate pier pile foundation construction, the stake distance of positions is suitably relaxed pile sinking quantity every day more than the 50m of two sides.
In the work progress, sedimentation, the horizontal movement of engineering structure and surrounding building are monitored; Lateral displacement is monitored to soil body deep layer; Underground water level, pore water pressure are monitored; Monitor in inclination and surrounding building crack to surrounding building.Analysis-by-synthesis produces the reason of sedimentation and displacement, feeds back in construction guiding construction.
According to the construction monitoring reflection, piling causes surrounding environment influence degree (maximum value) to be:
Noise: 96.3dB (pier 65m in the distance)
Vibration: 2.843 (apart from 13.8m)
Displacement: 22mm (ground-connecting-wall QW15)
All satisfy the environment control criterion of determining when going into operation.
Although invention has been described for the foregoing description, for the technician of the industry, still can do multiple variation to present embodiment, therefore, every employing similar variation of the present invention all should be listed protection scope of the present invention in.
