Description
Technical field
The invention belongs to civil engineering driven cast-in-place pile construction field, and in particular to a kind of driven cast-in-place pile filling concrete
The real-time measurement apparatus and its application method of height.
Background technology
Driven cast-in-place pile is an important method for the treatment of of soft foundation, by static pressure, hammering or vibration immersed pipe device, will be carried
The stake mould of flap valve shoe or concrete prefabricated pile top sinks to projected depth, is then placed in framework of steel reinforcement, and casting concrete, vibration is pulled out
Pipe, maintenance shaping, just forms the cast-in-place concrete pile of the different pile bodies and cross sectional shape of design.Filling concrete process
In, influx height is to assess one of important parameter of quality of concreting.Appoint and found the state《How is cast-in-situ bored pile concrete face absolute altitude
Measurement and control》One the article pointed out, generally we measure cast-in-situ bored pile filling concrete height by lining rope and weight, so
And, for driven cast-in-place pile, stake mould is located at more than ground tens of rice, traditional lining rope and the method for weight in filling process
It is difficult to realize, differentiate that driven cast-in-place pile stake mould inner concrete influx height mainly strikes pipe by hammering, judged according to sound, the party
Method is only applicable to concrete and pours into the situation that absolute altitude has met or exceeded ground, and differentiates extremely inaccurate, occurs often following
Problem：When penetration concrete surface is less than ground surface, if a tube drawing is highly excessive, pile top extracts concrete surface, causes
Broken pile or constriction；When concrete absolute altitude is close to earth's surface, then stake is long does not reach design standard for deficient filling, and superfilled then waste of materials is pulled out
Superfilled concrete trickles down earth's surface after pipe, forms crust layer, and cleaning pile crown is very difficult.
The content of the invention
Object of the present invention is to provide a kind of real-time measurement apparatus of driven cast-in-place pile filling concrete height and its
Application method, overcomes immersed tube bored pile concrete to pour into the problem of height is difficult to measurement.
The technical solution for realizing the object of the invention is：A kind of real-time measurement of driven cast-in-place pile filling concrete height
Device includes winding box, graduated scale, weight and fixed pulley, and graduated scale one end is connected through fixed pulley with weight, and the other end is with receiving
Line box is connected, and fixed pulley is fixed on a machine frame top；Weight is located at directly over driven cast-in-place pile stake mould so that after weight drop
Fall into the stake mould of driven cast-in-place pile.
The winding box is used for folding and unfolding graduated scale.
The graduated scale is soft, rollable, and itself is indeformable in the presence of weight.
The weight material is concrete, and the free subsidence in water is floated in concrete.
The weight is using the concrete for irrigating lot number.
A kind of application method of the real-time measurement apparatus of driven cast-in-place pile filling concrete height, method and step is as follows：
Step 1, stake machine install fixed pulley afterwards in place, and fixed pulley, which is fixed in a machine frame top, measurement process, highly to be begun
Do not change eventually, be transferred to step 2；
Step 2, pull out winding box in graduated scale free end, by graduated scale free end pass through fixed pulley, graduated scale from
It is connected by end with weight, adjusts winding box so that weight is located at directly over driven cast-in-place pile stake mould, it is ensured that fallen into after weight drop
In the stake mould of driven cast-in-place pile, this is the initial position a of weight0, winding box is adjusted on the premise of not changing weight position, is recorded
Now in winding box graduated scale initial readingl 0, winding box is not moved in follow-up measurement process, is transferred to step 3；
Step 3, unwrapping wire are by weight free-falling to ground, record graduated scale readingl 1, then piling machine bracket height bel 1- l 0, checked with piling machine actual height, piling machine posture adjusted according to check result, step 4 is transferred to；
Step 4, winding box take-up, reset weight, sink to a mould, stop immersed tube, let-down weight during immersed tube to designed elevation
Hammer to free-falling terminates, graduated scale reading in record winding boxl 2, now stake bottom absolute altitude bel 2-l 1, it is further with immersed tube depth
Contrast is checked, and the perpendicularity of immersed tube is judged according to check result, step 5 is transferred to；
Step 5, weight resetted, then concrete perfusion, stops unwrapping wire to weight free-falling after perfusion and terminate, record
Graduated scale reading in winding boxl 3, now filling concrete be highlyl 2-l 3, it is transferred to step 6；
Step 6, repeat step 5, obtain the influx height of any perfusion moment concrete, are transferred to step 7；
Step 7, treat this perfusion after the completion of, move stake position, repeat step 4, the concrete for measuring next pile pours into situation.
Compared with prior art, its remarkable advantage is the present invention：（1）Measurement direction can be changed by fixed pulley, realized
The real-time measurement of filling concrete height.
（2）Graduated scale two ends stress, tight, precision height during measurement.
（3）Weight is using perfusion lot number concrete for making, and measurement accuracy is high.
（4）Device is easy to operate, technology simple possible, practical.
（5）Driven cast-in-place pile filling concrete depth can be not only measured in real time, can also be tested immersed tube depth, demarcation immersed tube and be hung down
Straight degree.
