Abstract
The utility model relates to an underwater concrete tester, in particular to an underwater concrete pouring lifting height tester for solving the problem how to rapidly, accurately, economically and practically measure the position of an underwater concrete pouring surface. The underwater concrete pouring lifting height tester comprises a measuring rope, a measuring meter and a cone plummet. One end of the measuring rope is connected with the measuring meter and the other end of the measuring rope is connected with the cone plummet; a cavity is formed in the cone plummet; and a filling block is arranged in the cavity. The underwater concrete pouring lifting height tester has the advantages that the control effect is good; on the premise of ensuring the pouring quality, the pouring quantity of the concrete of a pile foundation is saved; and the underwater concrete pouring lifting height tester has good economic benefits.
Description
Technical field
The utility model relates to a kind of underwater concrete analyzer, and the concrete under water that in particular, how fast to relate to, mensuration underwater concrete accurate, economic and practical pours into the face position is built the lifting height analyzer.
Background technology
When pile foundation was carried out the underwater concrete perfusion, every certain interval of time should infer whether build height coincide with the concrete perfusion amount according to theory amount of building and actual relation between the amount of building.For guaranteeing the density and the intensity of pile foundation top concrete, the stake top mark height of perfusion should exceed certain altitude than design, is generally 0.5～1.0m on the other hand.This all needs the accurate fast measuring of underwater concreting height.Because of underwater concrete top is slurry coat method; The mensuration of building height generally is to decide with operator's feel with lining rope and plummet; The numerical value that different people draws has certain deviation, and this patent has provided the method that can accurately measure the concreting height according to law of buoyancy.
At present; Assay method all is to adopt traditional method; The plummet of promptly measuring the concreting height generally adopts the steel cone-shaped body; Inconsistent during mensuration because of its buoyancy suffered in slurry coat method and fresh concrete, the two at the interface penetration resistance obvious variation is arranged, operating personnel infer the concrete surface position in view of the above.But plummet and mud and fresh concrete buoyancy are inconsistent and form error at measurment, cause the mensuration out of true easily, thereby cause waste material, even build the underwater concrete height and can not satisfy Pile Foundations Design and code requirement.
The utility model content
Whether the purpose of the utility model just provides a kind of concrete under water and builds the lifting height analyzer and build height with accurate measurement and coincide with the concrete perfusion amount.
The utility model comprises lining rope, meter and taper plummet, one section connection meter of lining rope, and the other end connects the taper plummet, and taper is measured hammer and is contained cavity, is provided with filling block in the cavity.
Taper plummet in the utility model comprises upper hammer and the lower hammer through being threaded together.
It is fine that the advantage of the utility model is to control effect, under the prerequisite that guarantees pouring quality, practiced thrift the concrete amount of building of pile foundation, and good economic benefits is arranged.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:
Fig. 1 is the synoptic diagram of the utility model installment state;
Fig. 2 is the cut-open view of taper plummet in the present embodiment 2.
Embodiment
The utility model comprises lining rope 1, meter 2 and taper plummet 3, one section connection meter 2 of lining rope 1, and the other end connects taper plummet 3, and taper is measured hammer and is contained cavity 4, is provided with filling block 5 in the cavity 4.
The existence of filling block 5 causes the proportion of taper plummet and fresh concrete very approaching; When plummet just floods to pile foundation fresh concrete fully; Can stop to sink, and situation in time is reflected on the meter 2, thereby can determine the height of casting concrete more exactly.Among Fig. 1 10 is conduit, 8 by the slurry of survey height, 9 is slime water, 11 is ground.
Application in several pile foundation engineerings, its measuring error is generally in 10cm.The stake top mark height of regulation perfusion in the bridge standard should exceed certain altitude than design, and for guaranteeing the pile crown concrete quality, relatively conservative in the construction, general value is 0.5～1.0m.Less because of this method measuring error, in the practice of construction it highly is defined as 0.5m.
Embodiment 2
Mounting structure is with embodiment 1, and the taper plummet 3 in changing embodiment in the utility model comprises the upper hammer 6 and lower hammer 7 through being threaded together.Because this structure is a demountable structure, so filling block 5 is the fritter shown in the figure, this structure, when running into the measured material of different densities again, can be through changing filling block 5, the density of change filling block 5 adapts to different working environments.
