Description
Technical field
The invention belongs to the building surveying technical field, be specifically related to a kind of testing tool for the measurement of drilled pile sediment.
Background technology
Along with the development of Chinese Railway, Foundation Design is especially had higher requirement on the drilled pile basis.Accurately measuring drill pile hole bottom grain stillage is the effective way that guarantees and improve the drilled pile quality.Detection method to the sediment situation at the bottom of the drilled pile hole has plummet detection method, sampling box detection method and sediment instrument detection method at present.The three in use all exists not enough, specific as follows:
The plummet detection method needs to check continually before use with in the use, when wearing and tearing appear, numeral is unclear or mark numerical digit when moving, and then needs in time to change lining rope.Sediment thickness was more directly perceived at the bottom of this method detected hole, be a kind of method commonly used at present, but shortcoming was to depend on artificial judgement in concrete operations unduly, and the artificial result who judges often varies with each individual, and caused the degree of accuracy of this methods and results not high.
The sampling box detection method be after finish in clear hole, sampling box (opening box) hung the hole at the bottom of, and before the concrete perfusion, take out, the interior dregs thickness of box this moment namely is sediment thickness at the bottom of the hole.Its shortcoming is that the practical operation difficulty is bigger, if the sediment that takes out before the perfusion exceeds standard, also need continue clear hole, has the drawback of incuring loss through delay the duration and easily causing quality problems.
It is fixed that sediment instrument detection method needs at the measurement rower that advance, and uses in large-scale, key project at present.But shortcoming is that the instrument cost is higher, needs in the use to demarcate, and increases construction cost, is difficult to promote in medium and small project, so lack the testing tool of low cost, the measurement of high-precision drilled pile sediment on the market.
Summary of the invention
At the deficiency of existing drilled pile sediment measuring method, the invention provides a kind of simple in structure, easy to detect, monitoring tool that accuracy of detection is high, its concrete structure is as follows:
A kind of testing tool of measuring for the drilled pile sediment comprises lining rope, heavily bores piece 1, flat lid 2 and probe 3; Wherein,
Heavily bore piece 1 and be the cone of hollow; The tip of heavily boring piece 1 is provided with becket bridle 4, and becket bridle 4 is connected with an end of lining rope; The bottom surface of heavily boring piece 1 is provided with bolt hole 5;
" protruding " type structure of flat lid 2 for matching with bolt hole 5;
In addition, heavily bore in the cavity of piece 1 and be filled with sand.
In addition, bolt hole 5 is vertical through hole, and the length of bolt hole 5 and is located at the central authorities that heavily bore piece 1 bottom surface between 10 to 15mm.
In addition, the length of probe 3 is between 200 to 350mm.
Beneficial technical effects:
This product simple in structure, be connected firmly, not fragile, the life cycle of product is long;
This product can accurately be measured the drilled pile sediment thickness, improves the drilled pile construction quality;
The length of the chaining pin of this product and the shape of lower end can be according to the requirement of reality customizations, for example according to the sediment thickness of friction pile or end bearing pile; This product is specially adapted to the measurement of high-speed railway drilled pile sediment thickness;
The certainty of measurement height of product, detection method are simple, are fit to the use of medium and small project.

Concrete embodiment
Now be described with reference to the accompanying drawings structure of the present invention.
Referring to Fig. 1 and Fig. 3, a kind of testing tool of measuring for the drilled pile sediment comprises lining rope, heavily bores piece 1, flat lid 2 and probe 3; Wherein,
Referring to Fig. 5, heavily bore piece 1 and be the cone of hollow; The tip of heavily boring piece 1 is provided with becket bridle 4, and becket bridle 4 is connected with an end of lining rope; The bottom surface of heavily boring piece 1 is provided with bolt hole 5, and bolt hole 5 communicates with the cavity of heavily boring piece 1 inside;
Referring to Fig. 6, " protruding " type structure of flat lid 2 for matching with bolt hole 5;
Referring to Fig. 7, probe 3 is cylinder, and an end of probe 3 is provided with screw thread and matches with bolt hole 5;
Referring to Fig. 2 and Fig. 4, bolt hole 5 is connected with flat lid 2 or probe 3; Namely the cavity that will heavily bore in the piece 1 by flat lid 2 or probe 3 is airtight.When being used in combination, no matter flat lid 2 or the top of probe 3 are not all stretched in the cavity of heavily boring piece 1.
In addition, heavily bore the sand that has been filled with the counterweight effect in the cavity of piece 1.
Referring to Fig. 3 and Fig. 4, bolt hole 5 is vertical through hole, and the length of bolt hole 5 and is located at the central authorities that heavily bore piece 1 bottom surface between 10 to 15mm.
Referring to Fig. 4, the length of probe 3 is between 200 to 350mm.
During use, at first, with the lining rope bolt on becket bridle 4, and probe 3 is fixed on the bottom of heavily boring piece 1, after clear hole is carried out once in the hole that needs are measured, above-mentioned probe 3 and the combination of heavily boring piece 1 are transferred at the bottom of the hole by lining rope, when probe 3 inserts the sediment bottom, the degree of depth a that the record lining rope puts down proposes back and duplicate measurements with above-mentioned probe 3 and the combination of heavily boring piece 1, draws average X.
Subsequently, pull down and change flat lid 2 with being fixed on the probe 3 of heavily boring piece 1 bottom, flat lid 2 and the combination of heavily boring piece 1 are transferred at the bottom of the hole by lining rope, in the time of on the bottom of flat lid 2 is seated the sediment layer, the degree of depth b that the record lining rope puts down, above-mentioned flat lid 2 is proposed back and duplicate measurements with the combination of heavily boring piece 1, draw average Y.
At last, X and Y are subtracted each other, the difference of gained is the thickness of sediment layer.
