Description

Device for measuring depth of concrete pouring surface layer of underwater pile

Technical Field

The utility model relates to a building technical field especially relates to a measure device of pile concrete placement surface course degree of depth under water.

Background

At present, in the construction process of underwater piles, an important task is to determine whether the elevation of the top of underwater cast concrete meets the specified requirement. On site, construction operators generally tie the hoisting ropes marked with scales on thick reinforcing steel bars with the length of 30cm to manufacture simple hoisting hammers, and judge the height of a concrete pouring surface according to experience. The result error of the measurement treatment of the method is very large, and the influence of the laitance on the pile top cannot be eliminated.

In the process of underwater pile concrete pouring, the height of the top surface of the concrete and the depth of the embedded pipe of the guide pipe are measured in time, and the guide pipe is lifted and removed in time. However, for the experience judgment of the existing simple steel bar as the hanging hammer, the actual height of the poured concrete surface cannot be accurately measured, and the situation that the pile is broken due to excessive pipe drawing or the pouring is difficult due to too short pipe drawing often occurs. After the pile body is poured to the designed elevation, the specification and the design drawing also require a part of concrete to be over-poured, so that the concrete quality of the pile body is ensured. However, due to the fact that the existing judging method is large in error, only the laitance is generated after the pile is broken to the specified elevation, and the condition that pile connection has to be dug for quality safety of the pile is guaranteed, so that no problem exists, concrete is usually poured more, and concrete waste is caused invisibly. Therefore, a simple device for measuring the depth of a concrete pouring surface layer of an underwater pile is needed to facilitate construction.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, a measure device of pile concrete placement surface course degree of depth under water, including being used for surveying the detection mechanism of pile concrete placement surface course under water, a flexible stay cord 1 for hanging detection mechanism, flexible stay cord 1 is the inelastic rope, the length of the flexible stay cord 1 of unit weight is unchangeable in use and storage process, detection mechanism includes the survey of cylinder and fights mobile jib 2, survey of the fretwork of the toper shape and fight 3, 3 rigid couplings of surveying the fill are on survey the mobile jib 2, and the opening end of surveying the fill 3 faces up, the bottom of surveying the fill mobile jib 2 is equipped with conical head 4, the top rigid coupling of surveying the fill mobile jib 2 has rings 5, one end system of flexible stay cord 1 is on rings 5.

Survey fill 3 includes twelve uses survey fill mobile jib 2 as the center pin and arranges according to ring array's down the three connecting ring 32 that up diameter increases in proper order, every connecting ring 32 all with whole down tube 31 rigid coupling, every connecting ring 32's center pin and survey the center pin collineation of fill mobile jib 2. The flexible pull rope 1 is sleeved with a scale ring for marking the length in an interference manner, so that the length of the flexible pull rope 1 extending into the underwater pile hole can be known conveniently.

The bottom of the diagonal rod 31 is welded with the outer side of the main rod 2 of the measuring bucket, and the connecting ring 32 is welded with the diagonal rod 31. The length and the width of the gap enclosed between the inclined rod 31, the main rod 2 of the measuring hopper and the connecting circular ring 32 positioned at the bottom are both less than 5mm, so that the sand and the cement paste in the concrete can smoothly pass through, and the two stones are intercepted, thereby ensuring that the measuring hopper 3 can smoothly pass through a water layer and a laitance layer.

The utility model discloses a theory of operation: an operator drops the detection mechanism into the underwater pile hole through the portable flexible pull rope until the measuring bucket of the detection mechanism is intercepted by graded broken stones of an underwater pile concrete surface layer, when the flexible pull rope just begins to loose, the length h1 of the flexible pull rope stretching into the underwater pile hole is recorded, the length h2 between the top end of the measuring bucket and the hanging ring is obtained through measurement by a ruler, the sum of h1 and h2 is the height difference between the underwater pile concrete surface layer and the orifice of the underwater pile hole, and then whether the height of the underwater pile concrete surface layer reaches the height required by design is known. Because concrete and mud are not uniform in weight, the concrete and mud have strong viscous feeling. When the viscous feeling disappears and the detection device stably sinks, the detection device stops releasing, and an operator records the scale of the label on the flexible pull rope at the moment. And lifting and placing the probe up and down for 3 seconds, and then lifting the probe out. And observing whether the measuring hopper has stones in the concrete or not, and if yes, recording the depth as the effective depth of the underwater concrete pouring surface layer. If not, the secondary extraction measurement needs to be deepened.

The utility model discloses a measuring bucket volume is got the concrete stone degree of depth and is judged concreting concrete surface layer degree of depth under water, has avoidd and has leaned on the operation workman viscous to feel the experience problem of subjective definite concrete surface, has also avoided the laitance layer to the influence that the concrete interface judges. When the stones are taken out, the reading of the flexible measuring rope is the effective depth of the underwater concrete pouring surface layer, the underwater concrete pouring device is objective and convenient, the height of the underwater pile is greatly reduced under the condition of ensuring the reliable quality of the pile, and the waste of concrete and the subsequent pile breaking engineering quantity are further reduced.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
