Abstract
The utility model relates to sediment thickness survey instrument at the bottom of a kind of priming concrete pile hole.The purpose of this utility model is to provide easy to operate, detection is simple and sediment thickness survey instrument at the bottom of the priming concrete pile hole that accuracy rate is high, the measurement rope B of it comprises Metallic rod, one end is fastened on Metallic rod top measurement rope A, sheet metal and drawing sheet metal; The through hole passed perpendicularly through for Metallic rod is offered in the middle part of described sheet metal; The lower end of described Metallic rod is cut into cone structure shape.The utility model has the advantage of: the bottom design of Metallic rod becomes cone-shaped, during detection, the cone-shaped bottom of Metallic rod can directly be inserted bottom sediment, improves and measures accuracy rate; Closed by the slip cap establishing of metal tube and Metallic rod, when enabling Metallic rod and metal tube fall to stake holes, be in same sediment location point, reduce measuring error, simultaneously after Metallic rod inserts sediment, Metallic rod can play the effect of perpendicular positioning, prevents metal tube from tilting, and improves accuracy of measurement.
Description
Technical field
The utility model relates to sediment thickness survey instrument at the bottom of a kind of priming concrete pile hole.
Background technology
The bridge structure design of existing road construction is all use based on the underwater cast-in-place pile of punching (brill) hole, and at the bottom of design hole, the height major part on absolute altitude distance ground is at more than 50m.It is one of most important beasurement base of evaluation bearing capacity of pile foundation that perfusion pre-test controls sediment at the bottom of the hole of bored concrete pile, and hole depth is too high brings difficulty to sediment thickness at the bottom of measured hole.Before perfusion concrete, Measurement accuracy portals end sediment thickness, can carry out sediment thickness at the bottom of control punch as early as possible by clear hole, ensures the bearing capacity of pile foundation.Therefore, before rushing (brill) hole stake perfusion concrete, sediment thickness at the bottom of the hole of bored concrete pile is measured accurately particularly important.
In prior art, adopt standard water wave lining rope to add weight and be not less than sediment thickness at the bottom of the not too large weight exploration hole of 1Kg volume, when detecting, plummet likely stops at sediment, easily cause judge inaccurate.Meanwhile, when plummet detects sediment thickness, need repeated measurement sediment thickness, detection time is long.
Summary of the invention
The purpose of this utility model be to provide a kind of easy to operate, detect simple and sediment thickness survey instrument at the bottom of the priming concrete pile hole that accuracy rate is high.
The purpose of this utility model is achieved through the following technical solutions: sediment thickness survey instrument at the bottom of a kind of priming concrete pile hole, the measurement rope B of it comprises Metallic rod, one end is fastened on Metallic rod top measurement rope A, sheet metal and drawing sheet metal; The through hole passed perpendicularly through for Metallic rod is offered in the middle part of described sheet metal; The lower end of described Metallic rod is cut into cone structure shape.
It also comprises a metal tube, and described metal tube is slidably located in Metallic rod outside surface, and the bottom of described metal tube and the lead to the hole site place of sheet metal fix, and sheet metal and metal tube perpendicular, the described bottom measuring rope B is fixed on the upper end of metal tube.
Compared to prior art, the utility model has the advantage of:
1, the bottom design of Metallic rod becomes cone-shaped, and during detection, the cone-shaped bottom of Metallic rod can directly be inserted bottom sediment, improves and measures accuracy rate;
2, closed by the slip cap establishing of metal tube and Metallic rod, same sediment location point is in when enabling Metallic rod and metal tube fall to stake holes, reduce measuring error, simultaneously after Metallic rod inserts sediment, Metallic rod can play the effect of perpendicular positioning, prevent metal tube from tilting, improve accuracy of measurement.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Structural representation when Fig. 2 is the utility model use.
Label declaration: 1 Metallic rod, 2 measure rope A, 3 sheet metals, and 4 measure rope B, 5 cone structure shapes, 6 metal tubes, 7 mud, 8 sediments.
Embodiment
Below in conjunction with Figure of description and embodiment, the utility model content is described in detail:
The embodiment schematic diagram of sediment thickness survey instrument at the bottom of a kind of priming concrete pile hole provided for the utility model as illustrated in fig. 1 and 2, the measurement rope B4 of the measurement rope A2 that it comprises Metallic rod 1, one end is fastened on Metallic rod 1 top, sheet metal 3 and drawing sheet metal 3; The through hole passed perpendicularly through for Metallic rod 1 is offered in the middle part of described sheet metal 3; The lower end of described Metallic rod 1 is cut into cone structure shape 5.
Preferably, described in the present embodiment, sediment thickness survey instrument at the bottom of priming concrete pile hole also comprises a metal tube 6, described metal tube 6 is slidably located in Metallic rod 1 outside surface, the bottom of described metal tube 6 and the lead to the hole site place of sheet metal 3 fix, and sheet metal 3 is perpendicular with metal tube 6, the described bottom measuring rope B4 is fixed on the upper end of metal tube 6.
As shown in Figure 2, during use, Metallic rod 1 is inserted in metal tube 6, ensures that the bottom of Metallic rod 1 flushes with sheet metal 3 simultaneously as much as possible, then stretching measurement rope A2 and measurement rope B; Metallic rod 1 and metal tube 6 are synchronously put into stake holes, ensures the synchronism that measurement rope A2 and measurement rope B4 transfers as far as possible; When sheet metal 3 encounters the top of sediment 8, operating personnel can feel that the drawing gravitation measuring rope B4 can decrease, now by measurement rope A2 and measurement rope B4 separately, certain pulling force is kept to measurement rope B4, ensure that metal tube 6 is in plumbness (now metal tube 6 pairs of Metallic rod 1 have perpendicular positioning effect), then will measure the rope B4 bottom of continuing to transfer to Metallic rod 1 touches the end; Now put down gently and measure rope B4, sheet metal 3 is put in place with the top contact of sediment 8; Finally measure the drop that two are measured rope.
