Abstract
The utility model provides a height measurement appearance is used in underwater concrete bored concrete pile pile bolck elevation control construction, its characterized in that adopts thin wall polyethylene plastic pipe be the main material, and according to the barodynamics characteristics, the preparation of measuring apparatu bottom is spired, and the back lid adopts threaded connection covers to be fixed with after, and hangs the nose, and striking anti -corrosive paint layer is applied paint with a brush to whole. The utility model discloses can effectively solve the difficult problem of pile bolck elevation control, it is directly perceived effective, simple accurate. Guaranteed simultaneously that the effective stake of bored concrete pile is long, reduced the meaningless waste of concrete, guaranteed the intensity and the overall stability of bored concrete pile, reached swift, the energy -conserving efficient good result of construction, had spreading value.
Description
Technical field
The present invention relates to a kind of underwater concrete filling pile height of pile top and control construction height measurer, be applicable to Concrete Grouting Pale under bridge water.
Background technology
Concrete Grouting Pale traditional construction technique height of pile top controls main use lining rope and the side's of pouring amount estimation at present, advantage of this is that skilled operation, but lining rope controls or concreting side's amount controls all to accomplish accurately, the long too small or excessive defect of stake often occurs in work progress, and too small meeting causes the mass defect that bored concrete pile pile body effective length is not enough；Pile body superelevation causes waste of material serious and pile crown is abolished workload and increased, and the pile crown height of abolishing having even reaches 3 meters so that the height of pile top controlled when bored concrete pile pours the most succinct, effective becomes the problem that letter is to be solved.
Jinan ChengJian Group carries out research of technique for problem above, adjust construction technology, through field practice, summarize underwater grouting concrete height measurer and control bored concrete pile height engineering construction method, high process control difficulty, the long excessive or too small common quality defect of stake during solving filling pile construction.Intensity and the resistance to overturning aspect of bored concrete pile are significantly increased.
Summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of shorten construction period, overcome common quality defect underwater concrete filling pile height of pile top control construction height measurer.
It is an object of the invention to realize in the following manner:
The underwater concrete filling pile height of pile top of the present invention controls construction height measurer, it is characterized in that, including bonnet above and following cylinder, bonnet and cylinder are connected with each other, and using thin-walled vinyl tube is main material, according to barodynamics feature, cylinder body bottom is fabricated to taper, bonnet uses threaded, bonnet is fixed with and hangs nose, the rust preventive coating that overall brushing is eye-catching.
Height measurer, long 30cm, diameter 8cm, wall thickness 0.2cm.
The invention has the beneficial effects as follows:
Use the construction of underwater grouting concrete height measurer method, when pouring underwater concrete, the concrete of same condition is poured in prefabricated height measurer, when concreting to design height of pile top, height measurer is put into stake holes, owing to mud is different with the proportion of concrete, height measurer can rise with underwater concreting, after height measurer rises to preset height, measuring and check, qualified rear stopping pours.Can effectively solve the difficult problem that height of pile top controls compared with traditional handicraft, so can ensure that elevation precise control, effectively, the most simple and easy to do.Can ensure that again bored concrete pile effective length, reduce concrete unnecessary waste, it is ensured that the intensity of bored concrete pile and resistance to overturning, reached the good result of quick construction, efficient energy-saving.Obtaining construction unit's abundant affirmation, social benefit is notable.
Accompanying drawing explanation
Fig. 1 is underwater grouting concrete height measurer schematic diagram.
In figure, 1 cylinder, 2 bonnets, 3 hang nose, 4 tapers.
Detailed description of the invention
With reference to Figure of description, the method for the present invention is made following detailed description of.
nullA kind of underwater concrete filling pile height of pile top controls construction method,By underwater grouting concrete height measurer，When pouring underwater concrete，The concrete of same condition is poured in prefabricated height measurer，The deadweight making height measurer is slightly below same volume weight concrete，The proportion of mud is 1.1mg/mm3，The proportion of concrete is 2.4mg/mm3，Elevation controller proportion is more than mud balance，And the proportion of slightly below concrete，Height measurer deadweight more than its in mud buoyancy be slightly less than again its buoyancy in concrete，Therefore height measurer is put into stake holes，Its position is placed exactly in mud and underwater concrete intersection，Utilize measuring instrument different with the buoyancy in concrete at mud，With underwater concreting，Height measurer rises therewith，After rising to preset height，Measure and check，Stop after qualified pouring.
Height measurer, including bonnet above and following cylinder, bonnet and cylinder are connected with each other, using special thin-walled vinyl tube is main material, according to barodynamics feature, being fabricated to taper 4 bottom measuring instrument cylinder 1, bonnet 2 uses threaded, it is fixed with on bonnet and hangs nose 3, the rust preventive coating that overall brushing is eye-catching.
Height measurer, long 30cm, diameter 8cm, wall thickness 0.2cm.
Claims (2)
1. a underwater concrete filling pile height of pile top controls construction height measurer, it is characterized in that, including bonnet above and following cylinder, bonnet and cylinder are connected with each other, bonnet uses threaded, being fixed with on bonnet and hang nose, cylinder body bottom is fabricated to taper, the rust preventive coating that overall brushing is eye-catching.
Underwater concrete filling pile height of pile top the most according to claim 1 controls construction height measurer, it is characterised in that long 30cm, diameter 8cm, wall thickness 0.2cm.
