Description
Technical field
The utility model belongs to the technical field of drilled pile underwater concrete construction, is specifically related to a kind of underwater concreting absolute altitude monitor.
Background technology
In pile foundation concrete perfusion work progress, if the high too high meeting of castinplace pile top mark causes concrete to waste, if perfusion absolute altitude deficiency, stake top can be caused off quality.Therefore, strictly must control concrete groundwater increment, then need to measure concrete influx height in filling process.Traditional measuring method adopts lining rope to measure filling concrete height, but when utilizing the method to measure, if measurement not in time or lining rope tup is overweight easily sinks in concrete, then can cause the super filling of concrete, cause pile crown excessive, waste time and energy during cutter pile crown, added cost; If tup kicks the beam and easily held up by upper strata laitance, can not determine bottom lining rope, whether tup sinks to concrete, workman can be misled if any mudstone and think it is concrete, cause measure inaccurate, the quality problems such as cause pile crown off quality.
For bridge engineering pile foundation construction, adopt the artificial lining rope that irregularly uses to measure filling concrete height during drilled pile construction underwater concreting before, for the stake of long 40 rice diameter 1.25 meters of a pile, perfusion pore-forming at least needs to measure more than 5 times with lining rope, qualified in order to ensure stake top mark eminence concrete quality as far as possible, during concrete perfusion, high will to exceed design stake top mark high 1.0 meters for top mark, easily cause pile crown excessive, cause costly waste and cut a hole pile crown time-consuming, take a lot of work, stake top quality is also difficult to control, and often causes and does over again.
Summary of the invention
The utility model, in order to monitor the influx height in pile foundation filling concrete process in time, exactly, provides a kind of underwater concreting absolute altitude monitor.
The utility model adopts following technical scheme:
A kind of underwater concreting absolute altitude monitor, comprise fixed support, graded tube and be provided with the sampling dish of counterweight, described graded tube is vertically installed, the upper end of graded tube to be installed on fixed support by horizontal fixed axis and by the locking of scale lock, sampling dish is installed on the lower end of graded tube and moves up and down with graded tube.
Described fixed support comprises back shaft, job platform and casing, and back shaft and job platform connection in T shape, the two ends of job platform are by casing supported, and described graded tube is connected to the side of job platform.
Described casing is semicircle globoidal structure.
Described sampling dish is cube structure, one of them side of side's body is active open, the keying of active open (8) is controlled by linkage pull rod, the junction of linkage pull rod lower end and active open is provided with spring, the epimere of linkage pull rod is arranged on horizontal fixed axis, and the upper end of linkage pull rod is provided with flexible handle.
The stage casing of described linkage pull rod is also provided with the loop chain be connected with graded tube together.
The utility model has following beneficial effect:
1, to utilize graded tube can embody stake top filling concrete in time, accurately, intuitively dynamic for this monitor, effectively prevent because influx height controls the super filling of the inaccurate concrete caused, cause pile crown excessive, waste time and energy during cutter pile crown, the quality problems such as added cost consumed above set limit by material, pile crown is off quality, recruitment quantity reduces original 1/3rd, concrete quantity consumed reduces 5 percent, and economic benefit is obvious.With the on average super design elevation 1.0 meters calculating of every pile base concrete influx height, consume above set limit concrete V=3.14*(1.25/2)
2* 1=1.22 cubic meter, the railway engineering Pile Foundations Design quantity of one 40 kilometers about 7000, concrete is wasted 8540 cubic metres (not comprising 1.5 meters, a footpath).
2, whether there are rubble and concrete sample by checking in sampling dish, can judge that whether stake top quality is qualified in time, effectively improve the construction quality on stake top.

Detailed description of the invention
By reference to the accompanying drawings, detailed description of the invention of the present utility model is described further:
A kind of underwater concreting absolute altitude monitor as shown in Figure 1, 2, comprise fixed support, graded tube 4 and be provided with the sampling dish 9 of counterweight, described graded tube 4 is vertically installed, the upper end of graded tube 4 to be installed on fixed support by horizontal fixed axis 2 and by scale lock 1 locking, sampling dish 9 is installed on the lower end of graded tube 4 and moves up and down with graded tube 4.Described fixed support comprises back shaft, job platform 3 and casing 7, back shaft and job platform 3 connection in T shape, and the two ends of job platform 3 are supported by casing 7, and described graded tube 4 is connected to the side of job platform 3; Described casing 7 is semicircle globoidal structure, and the inner space of globoidal structure is for installing the device such as graded tube 4, sampling dish 9, and its structure itself serves supporting role.
As shown in Figure 1, described sampling dish 9 is cube structure, 3mm steel plate with holes is adopted to be made, physical dimension is 20*20*10cm, one of them side of side's body is active open 8, and the keying of active open 8 is controlled by linkage pull rod 5, and the junction of linkage pull rod 5 lower end and active open 8 is provided with spring 6, the epimere of linkage pull rod 5 is arranged on horizontal fixed axis 2, and the upper end of linkage pull rod 5 is provided with flexible handle.Linkage pull rod 5 adopts the steel pole of diameter 5mm, and the upper end of steel pole arranges installation by horizontal fixed axis 2, and centre is provided with one loop chain, plays the effect of stable linkage pull rod.The active open of linkage pull rod lower end link sampling dish, upper end link flexible handle, by the switch of hand control sampling dish side active open, handle lower end arranges spring, normal when using spring straining side door close, portable pull bar when needing to open.When monitoring filling concrete height to design height, by the active open on pull bar interlock sampling dish, open lateral opening, press down whole device 10cm, concrete is entered in sampling dish, and then closes active open by pull bar, propose whole device, check whether have rubble and concrete sample in sampling dish, judge that whether stake top quality is qualified.
Because the lock value=horizontal fixed axis absolute altitude-stake top mark of scale lock is high, by lock value and horizontal fixed axis absolute altitude then can convert draw actual measurement hit nail absolute altitude, namely after concrete arrives stake top mark height, touch sampling dish 9, then sampling dish promotes sampling dish along with concrete surface raises again, scale steel pipe upwards promotes, can visual inspection influx height, measured value and design load are contrasted.
Utilize detector described in the utility model, when solving underwater concreting, influx height controls the problems, particularly cost waste problem such as inaccuracy, top concrete be off quality, time-consuming.Therefore, compared with traditional metering system, this high monitor has simple to operate, time saving and energy saving, operating efficiency is high, the feature that improves workmanship, to reduce costs etc.
