Description
Technical field
A kind of device of measuring rotary digging drilling hole stake sediment layer thickness of the utility model, relates to bored pile construction field.
Background technology
Cast-in-situ bored pile with its wide accommodation, the advantage such as bearing capacity of single pile is high, construction noise is low, it is little to vibrate and unit price is low, in all kinds of construction works, be used widely.Increasing along with skyscraper, also more and more higher to the requirement of bearing capacity of pile foundation.But due to the singularity of construction process for bored pile, the factor of its bearing capacity in being constructed affects larger, and particularly at the bottom of hole, sediment layer has a strong impact on pile foundation quality.Therefore,, in work progress, the Detection & Controling of sediment thickness at the bottom of reinforced hole, are one of key measures ensureing Construction Quality for Bore Filling Pile and bearing capacity of pile foundation.
Operating technique level prosperity in prior art, although have the instrument of the special measurement sediment thickness of group: sediment instrument, it adopts computer technology and supporting special software, the every detection data of Graphics Processing and curve in real time, the report of Fast Drawing hole quality, but testing cost is higher, hinder the use in project under construction.In engineering practice, need to there be a kind of economy, convenience, device simple, that easily go.
Summary of the invention
The utility model provides a kind of device of measuring rotary digging drilling hole stake sediment layer thickness, and it is simple in structure, economic and practical, measurement is accurately convenient, has solved well pile bottom sediment and has measured the large problem of difficulty.
The technical scheme that the utility model is taked is:
A kind of device of measuring rotary digging drilling hole stake sediment layer thickness, comprise steel ruler, triangular support disk, described triangular support disk is fixed three long reinforcing bars by steel disc edge and is formed, the circular hole of band silk mouth is offered at described steel disc center, and reinforcing bar screw rod is connected with steel disc by described circular hole.
Described steel disc is the thin steel disk of thickness 3mm.The long reinforcing bar of 200mm that described long reinforcing bar is φ 8.The circular hole of described band silk mouth, its aperture is 10mm.The long reinforcing bar of 200mm that described reinforcing bar screw rod is φ 10.Described steel ruler adopts 50m steel tape.
A kind of device of measuring rotary digging drilling hole stake sediment layer thickness of the utility model, technique effect is as follows:
Measure for the first time: connect φ 10 reinforcing bar screw rods from steel disc top silk, flush in φ 10 reinforcing bar screw rod tops fixed 0 scale of 50m steel ruler; Measure for the second time: connect φ 10 reinforcing bar screw rods from steel disc bottom silk, flush in bottom, the steel disc center of circle fixed 0 scale of 50m steel ruler; Sediment thickness is the margin of measurement of twice measurement.
Cast-in-situ bored pile with its wide accommodation, the advantage such as bearing capacity of single pile is high, construction noise is low, it is little to vibrate and unit price is low, in all kinds of construction works, be used widely.The utility model apparatus structure is simple, and economic and practical, measurement accurately facilitates.Solve well pile bottom sediment and measured the large problem of difficulty, in practice of construction, used well.Meanwhile, there is good operability, can be widely used in pile foundation construction.

Embodiment
As shown in Figure 1 and Figure 2, a kind of device of measuring rotary digging drilling hole stake sediment layer thickness, comprises steel ruler 1, triangular support disk.Described triangular support disk is made up of steel disc 2 edges three long reinforcing bars 3 of fixing welding, and the circular hole 4 of band silk mouth is offered at described steel disc 2 centers, and reinforcing bar screw rod 5 is connected with steel disc 2 by described circular hole 4.
Described steel disc 2 is the thin steel disk of thickness 3mm.The long reinforcing bar of 200mm that described long reinforcing bar 3 is φ 8.The circular hole 4 of described band silk mouth, its aperture is 10mm.The long reinforcing bar of 200mm that described reinforcing bar screw rod 5 is φ 10.Described steel ruler 1 adopts 50m steel ruler.
Operation steps:
Step 1: burying underground in steel casing 6 processes, utilize spirit-leveling instrument to measure, make on steel casing 6 consistent along absolute altitude.
Step 2: as shown in Figure 3, connect reinforcing bar screw rod 5 from triangular support disk top silk, flush in reinforcing bar screw rod 5 tops fixed 0 scale of steel ruler 1; Triangular support disk is transferred to pile foundation bottom 7, read apart from the reading L1(that on steel casing 6 along steel ruler 1 is in millimeter).
Step 3: as shown in Figure 4, connect reinforcing bar screw rod 5 from steel disc 2 bottom silks, flush in steel disc 2 bottoms, the center of circle fixed 0 scale of steel ruler 1; Steel disc 2 is transferred to pile foundation bottom 7, and sediment layer 8 upper surface of pile foundation bottom 7 support steel disc 2, then read on steel casing 6 along steel ruler 1 reading: L2(is in millimeter).
Step 4: the steel ruler reading L1 that reads by second step, add that 200mm reinforcing bar is long, deduct the 3rd step gained steel ruler 1 reading: L2 again, be the thickness of sediment layer 8.
That is: sediment layer 8 thickness=L1+200mm-L2.
