Description

PHC prestressed pipe pile soil-retaining cover plate

Technical Field

The utility model relates to the field of building construction, in particular to a PHC prestressed pipe pile soil retaining cover plate.

Background

In the prior art, in the pile feeding construction process of the PHC tubular pile, because the pile top is positioned in the soil body, due to poor cohesiveness of the soil body, or due to the fact that the soil body forms flowing plastic soil by rainwater and underground water, or due to the fact that the soil body is reinforced at the bottom of a deep foundation pit, a large amount of soil or hardened cement soil still exists in the last PHC tubular pile after the subsequent earthwork excavation is finished, core filling operation of the tubular pile is affected, and large amount of labor, time and cost are needed for cleaning up the cement soil at a deeper part in the tubular pile, and core filling of the tubular pile is a key step of basic construction, so that core picking is very important, if core picking construction is not met, the PHC tubular pile is used as an engineering pile, and original advantages are lost.

At present, the method for cleaning soil in a tubular pile is to use a high-pressure water gun for washing, but because a pile hole is completely filled with hardened cement, water and soil and is compacted, if the pile hole is directly washed by the high-pressure water gun, mud can flow, pollute and invade a foundation or a cushion layer, therefore, a Luoyang shovel is required to firstly clean the soil with the height range of 500mm of the pile top, and then the high-pressure water gun is used for washing and replacing the mud. And after the sludge and the slurry in the pipe are completely discharged, performing reinforced concrete core-filling construction. This method has several significant disadvantages:

the water used for replacing all the slurry is large, for example, the water needed for a 50m PHC-B500(100) pipe pile is about 3m³The cost is increased inevitably;

secondly, the construction period is influenced. More labor and time are wasted in cleaning the cement soil in the PHC tubular pile;

in part of foundation pit engineering with the supporting beams, the core drawing work is influenced by the net height of the supporting beams and cannot be effectively operated;

and fourthly, in the construction process of the foundation engineering, due to the operation of soil quality and other on-site mechanical equipment, a large amount of sludge is generated to submerge the height of the top of the tubular pile, is not easy to be found by workers during operation, is easy to step into a pile hole, is easy to fall and hurt if the height is small, and can cause serious safety accidents if the height is large.
