Description
Technical field
The utility model relates to a kind of building piling construction servicing unit, particularly pile penetration monitoring device in a kind of PHC pile tube pile driving process.
Background technology
At present, in PHC pile tube pile driving process, pile penetration monitoring mostly adopts interim scale to be bonded on pile follower bar or adopts crayon to be painted on Pile feeder, then observes with level gauge.For subsurface geology complicated condition, without typical geology section, PHC pile tube pile sinking difficulty is large, and pile follower absolute altitude is darker; Accurately and timely pile penetration monitoring is even more important.Adopt above monitoring mode, not only time-consuming, take a lot of work, operation inconvenience, and strengthen field control difficulty, as PHC pile tube pile sinking absolute altitude does not reach design elevation at the scene, but because of not promptly and accurately pile penetration monitoring, may cause that blow counts is many, pile body is tired or pile crown is damaged, rate of loss pile is high.Cause larger economic loss.
Utility model content
Technical problem to be solved in the utility model is to provide pile penetration monitoring device in a kind of PHC pile tube pile driving process, and structure is simple, and it is convenient to monitor, and reduces construction cost, ensures pile sinking quality, reduces rate of loss pile.
For achieving the above object, pile penetration monitoring device in a kind of PHC pile tube of the utility model pile driving process, it comprises pile follower bar, scale and pile follower cap, described pile follower masthead portion is fixedly installed circular pile follower masthead plate, pile follower cap is arranged on pile follower bar and PHC pile tube contact jaw by being welded and fixed, pile follower cap 5 adopts the steel plate of δ=12 ㎜ to make, high 300mm, hanger is fixedly installed in pile follower bar bilateral symmetry, described scale is fixedly installed on pile follower bar, scale is that ф 6 round steel is made, scale range from 1000mm on pile follower cap in 1000mm under pile follower masthead plate, this scale gauge length is 30mm.
Pile penetration is monitored: in pile follower process with natural ground for object of reference, range estimation scale and record blow counts, calculate pile penetration, finally determine to stop hammer.
Pile follower cap: then because pile sinking difficulty is large, hammer jump degree is higher, prevents pile follower bar and PHC pipe pile termination eccentric force, reduces PHC pile tube at pile follower pile head loss percentage.
Pile penetration monitoring device in a kind of PHC pile tube pile driving process that the utility model proposes, not only structure is simple, and it is convenient to monitor, and reduces construction cost, ensures pile sinking quality, decreases rate of loss pile.
Accompanying drawing explanation
Fig. 1 is pile penetration monitoring device structural representation in a kind of PHC pile tube pile driving process.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
See accompanying drawing, pile penetration monitoring device in a kind of PHC pile tube pile driving process, it comprises pile follower bar 1, scale 4 and pile follower cap 5, described pile follower masthead portion is fixedly installed circular pile follower masthead plate 2, pile follower cap is arranged on pile follower bar and PHC pile tube contact jaw by being welded and fixed, pile follower cap 5 adopts the steel plate of δ=12 ㎜ to make, high 300mm, hanger 3 is fixedly installed in pile follower bar bilateral symmetry, described scale is fixedly installed on pile follower bar, scale is that ф 6 round steel is made, scale range from 1000mm on pile follower cap in 1000mm under pile follower masthead plate, this scale gauge length is 30mm.
Pile penetration is monitored: in pile follower process with natural ground for object of reference, range estimation scale and record blow counts, calculate pile penetration, finally determine to stop hammer.
Pile follower cap: then because pile sinking difficulty is large, hammer jump degree is higher, prevents pile follower bar and PHC pipe pile termination eccentric force, reduces PHC pile tube at pile follower pile head loss percentage.
Pile penetration monitoring device in a kind of PHC pile tube pile driving process that the utility model proposes, not only structure is simple, and it is convenient to monitor, and reduces construction cost, ensures pile sinking quality, decreases rate of loss pile.
