Abstract
A tool for measuring the thickness of sinking slag on hole bottom of a bored pile comprises a measurement rope, and a metal measurement hammer fastened to the bottommost end of the measurement rope, wherein the measurement rope is composed of a sheath layer and a core layer; the sheath layer is sheathed on the outer side of the core layer in a loose fit manner; the metal measurement hammer is fastened to the lower end of the core layer; a vertical sleeve is connected with the lower end of the sheath layer; a horizontal bottom sheet is arranged at the lower end of the vertical sleeve and is fixedly connected with the vertical sleeve as a whole; the metal measurement hammer is sheathed in the vertical sleeve in a loose fit manner; and the upper end of the core layer is exposed out of the sheath layer. The measurement tool can objectively measure the thickness of sinking slag on the hole bottom of the bored pile without the need of the subjective determination of engineers based on experience and hand feeling.
Description
Technical field
The invention belongs to a kind of building construction measurement equipment, be specifically related to a kind of tools for measuring thickness of drill pile hole bottom grain stillage.
Background technology
Sediment belongs to loose structure at the bottom of the hole of drilled pile, and the existence of sediment or loosened soil is to influence the conforming key factor of drilled pile bearing capacity and basis at the bottom of the hole.When at the bottom of the hole during residual thicker sediment, stake bottom rigidity is reduced, allowable bearing descends.So sediment thickness is an indispensable ring in the drilled pile construction at the bottom of clear hole quality, the measured hole, the sediment thickness h of job specifications after to the clear hole of drilled pile has clearly regulation, promptly to stanchion: h＜10cm, to friction pile: h＜30cm.The existing instrument of measuring tools for measuring thickness of drill pile hole bottom grain stillage generally is to adopt 50 meters lining ropes, and the lining rope lower end has bound the metal plummet.The metal plummet is short strip shape, generally adopts the bar dowel of about 2 centimetres of 2-4 root diameters to close up and is welded into one.Lower, raise lining rope repeatedly by Utility Engineers's hand of measuring sediment during measurement, the metal plummet is constantly vertically thrust repeatedly extract the sediment layer then,, judge the sediment layer thickness with feel and experience thus at the resistance of this process sensation sediment layer.But because under the various geological conditions, particle diameter, viscosity, the component of sediment vary at the bottom of each pile hole, sediment is also different to the resistance performance of bar dowel plummet at the bottom of each pile hole.Therefore, existing tools for measuring thickness of drill pile hole bottom grain stillage can only be to carry out subjective judgement by feat of slip-stick artist's feel and experience during use, and can't objectively measure judgement, has erroneous judgement possibility greatly.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of tools for measuring thickness of drill pile hole bottom grain stillage at the above-mentioned deficiency of prior art, and it can objectively measure judgement to drill pile hole bottom grain stillage thickness.
For realizing above purpose, tools for measuring thickness of drill pile hole bottom grain stillage of the present invention comprises lining rope, bound a metal plummet at the lining rope lowermost end, its principal feature is, described lining rope is made up of sheathcoat and sandwich layer, be enclosed within to the sheathcoat loose fit sandwich layer periphery, described metal plummet is bound in lining rope sandwich layer lower end; Lining rope sheathcoat lower end links vertical sleeve, and vertical sleeve lower end is provided with horizontal egative film, and horizontal egative film and vertical sleeve fixedly are connected as a single entity; Be enclosed within the vertical sleeve to the loose fit of metal plummet; Expose outside sheathcoat the sandwich layer upper end.
The present invention has the following advantages and effect:
When 1, the present invention measures the drilled pile sediment thickness, plummet is thrust in the sediment layer, and horizontal egative film is blocked in above the sediment, lining rope sandwich layer and sheathcoat are misplaced, the length of dislocation is exactly sediment thickness, just can calculate sediment thickness by calculating the length variations of exposing outside the sheathcoat lining rope sandwich layer upper end, can measure sediment thickness objectively thus, and need not lean on slip-stick artist's experience and feel to carry out subjective judgement.

Fig. 2 is the another kind of user mode synoptic diagram of specific embodiment shown in Figure 1.
Embodiment
Embodiment one
As shown in Figure 1, this tools for measuring thickness of drill pile hole bottom grain stillage comprises lining rope, and lining rope is made up of sheathcoat 1 and sandwich layer 2, is enclosed within to sheathcoat 1 loose fit sandwich layer 2 peripheries, bound a metal plummet 3 at the lining rope lowermost end, described metal plummet 3 is bound in lining rope sandwich layer 2 lower ends; Lining rope sheathcoat 1 lower end links vertical sleeve 4, and vertical sleeve 4 lower ends are provided with horizontal egative film 5, and vertical sleeve 4 and horizontal egative film 5 fixedly are connected as a single entity; Be enclosed within the vertical sleeve 4 to 3 loose fits of metal plummet; Expose outside sheathcoat 1 sandwich layer 2 upper ends; Lining rope sandwich layer 2 upper ends are provided with scale.
The foregoing description use may further comprise the steps: a, before putting down metal plummet 3 at the bottom of the stake hole, regulate the relative position relation of metal plummet 3 and vertical sleeve 4, make metal plummet 3 bottoms concordant with horizontal egative film 5, the length X outside sheathcoat 1 is exposed in record lining rope sandwich layer 2 upper ends; B, hold lining rope 1 upper end, at the bottom of the stake hole, put down metal plummet 3, touch sediment 6 at the bottom of the hole to metal plummet 3 bottoms and horizontal egative film; C, continue to make the metal plummet to thrust sediment layer 6, metal plummet lower end touches supporting course (lithosphere) 7, horizontal egative film 5 then is blocked in above the sediment layer 6, and lining rope sandwich layer 2 and lining rope sheathcoat 1 are misplaced, and writes down the length Y that exposes on the sandwich layer outside sheathcoat once more; D, deduct the length Y of record for the second time with the length X of record for the first time, getting its result of calculation is sediment thickness.
