Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0021] Such as Figure 1-Figure 3 As shown, a method of anti-crowding and vibration isolation based on prestressed pipe pile construction, the method includes: drilling a plurality of isolation holes 3 on the ground 5 between the construction area 1 of the prestressed pipe pile and the building 2 , all isolation holes 3 form an isolation zone; bellows 4 are placed in each isolation hole 3 to weaken or eliminate the soil squeezing effect through the shrinkage deformation (mainly radial shrinkage) of bellows 4, and the inside of bellows 4 is The hollow tube hole can well block the transmission of vibration waves and play a role of vibration isolation.
[0022] In one embodiment, as...

The invention discloses an anti-crush soil and vibration isolation method based on prestressed pipe pile construction. The method includes: drilling a plurality of isolation holes on the ground between the construction area of the prestressed pipe pile and the building, and all The isolation holes are used to form an isolation zone; then a bellows is placed in each isolation hole. The invention can effectively reduce the vibration and soil squeezing effect during the construction of the prestressed pipe pile, and is beneficial to protect the surrounding road surface and the building environment.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-crush soil and vibration isolation method based on prestressed pipe pile construction. Background technique [0002] In view of the characteristics of fast construction speed, high work efficiency, reliable pile quality and low cost of prestressed pipe piles, prestressed pipe piles are more and more widely used in pile construction, but the construction of prestressed pipe piles will produce more Large soil squeezing effects and vibrations, such as vibration uplift of shallow soil and lateral extrusion of deep soil, will cause damage to surrounding roads and buildings, and will also have adverse effects on the surrounding building environment and underground pipelines. Meet construction needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-cold soil and vibration isolation method based ...
