Description
Technical field
The utility model relates to a kind of drilling pile depth detection apparatus, and especially a kind of revolving dug Settled-material detection apparatus at the bottom of a drilling pile.
Background technology
In order to reduce the deviation of the dark and design stake of actual stake between dark, guarantee simultaneously machinery revolve dig a drilling pile at the bottom of sediment thickness satisfy code requirement, often to revolve machinery in work progress and dig a drilling pile and deeply reach pile bottom sediment and unify to detect.Dig stake and belong to underground concealed engineering because machinery revolves, do not adopt the retaining wall pile-formation process under most of condition, after having caused machinery to revolve digging a pore-forming, can not manually descend the hole to carry out the dark and pile bottom sediment thickness of stake detects, and there is no at present a kind of scientific and effective detection method, therefore machinery revolve dig a pore-forming after, often can not effectively detect revolve dig the stake the degree of depth and pile bottom sediment thickness.As the important component part that the pile foundation hole quality detects, deeply whether drilling pile meet design requirement, whether pile bottom sediment thickness satisfies code requirement will directly affect the mechanical property of stake after follow-up pile foundation concreting and the quality of pile foundation quality.Therefore in order better to control the dark and pile bottom sediment thickness of stake, after the pile foundation pore-forming, the dark and pile bottom sediment of stake detects and seems especially important.
The utility model content
Revolve for solving existing machinery the problem that a pore-forming can not manually descend dark the and pile bottom sediment thickness of hole measurement stake of digging, the utility model provide a kind of not only can detect pile bottom sediment thickness, simultaneously but can detect the dark and device structure of drilling pile simply, revolving of low cost of manufacture dig Settled-material detection apparatus at the bottom of a drilling pile.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of revolving dug Settled-material detection apparatus at the bottom of a drilling pile, comprises and measures rope, and described measurement rope one end is provided with pulley, and the other end is provided with the measurement dish, and described measurement dish is made of card and supporting leg, and described pulley is located on steel pipe support.
Described measurement rope is provided with scale, and it is lift end that described measurement rope is walked around pulley one end.
Connect with fastener between described steel pipe support steel pipe, described steel pipe support upper end is provided with pulley.
Described supporting leg is vertical at below card, and supporting leg and card are by screwed connection.
Described supporting leg exposes the card partial-length greater than 5cm.
Described card is provided with draw ring, and described draw ring is connected with the measurement rope.
The beneficial effects of the utility model are:
The utility model both can detect pile bottom sediment thickness, simultaneously can detect drilling pile again dark, provided a kind of scientific and efficient solution for revolving pile bottom sediment thickness and the dark detection difficult problem of stake of digging after a pore-forming.Guaranteed pile bottom sediment and the stake dark next step working procedure that enters under the prerequisite that meets design requirement, avoid because of pile bottom sediment and the stake dark can't accurately a detection cause the architecture quality potential safety hazard; The utility model structural principle is simple, and swift and convenient to operate effective, raw material are simple, and are economical and practical.

In figure, 1. disk, 2. the reinforcing bar supporting leg, 3. measure rope, 4. car silk circular hole, 5. steel pipe support, 6. pulley.
The specific embodiment
As Figure 1-Figure 4, a kind of revolving dug Settled-material detection apparatus at the bottom of a drilling pile, forms by measuring rope 3, pulley 6, triangular steel pipe holder 5, car silk disk 1 with holes, car silk reinforcing bar supporting leg 2.Car silk disk 1 with holes is the thick steel disk of 2cm, disk diameter 20cm, the hole 4 that to bore respectively a diameter on the equilateral triangle tripod point that is inscribed within disk 1 center of circle be 2cm, hole 4 is the hole with the car silk, the dark 2cm in hole 4, reinforcing bar supporting leg 2 is the reinforcing bar of diameter 2cm, dig the drilling pile deposit control in 5cm because revolving by code requirement, surpassing 5cm is to carry out hole processing clearly, just can carry out next process until meet code requirement, therefore the Φ 20 secondary steel of desirable 20cm length are as supporting leg 2, supporting leg 2 one end car silks and can with disk 1 on car silk circular hole 4 freely tighten or unclamp.Measure rope 3 for indicating scale and minimum scale is the measurement rope commonly used of 5cm.
Triangular steel pipe holder 5 is comprised of three steel pipes, and the support upper end is fixed with fastener and pulley 6 is fixed in the support upper end, can adopt the steel pipe that is of a size of Φ 48 * 3.6 to form steel pipe support 5.
Measure rope 3 one ends and be connected with disk 1 top draw ring, the other end passes the pulley 6 on a ventral triangle steel pipe support 5, is pulled by the testing staff, plays the effect of oscilaltion detector.
Implementation process of the present utility model is:
Revolve dig a pore-forming after, push up in stake and install steel pipe support 5, pile bottom sediment detector set with 3 supporting legs 2 is installed and is installed in a hole, the operating personnel measures rope 3 by pulling, just but free lifting pile bottom sediment detector, at first tighten three reinforcing bar supporting legs 2 for 1 time at the steel disk, makes three supporting legs 2 tighten rear ride out h1 consistent, the measurement dish is put into a hole by pulley 6, read a place, top at the bottom of Settled-material detection apparatus drops to and when stopping free subsidence and measure rope 3 reading h2; Then three supporting legs 2 with steel disk 1 remove, and repeat above step, read reading h4 when disk 1 touches bottom, hole sediment; Suppose that h3 is disk 1 thickness, (h1+h2+h3)-(h3+h4)=h1+h2-h4, both measurement result added the poor of reinforcing bar supporting leg 2 ride outs and measurement result for the second time for the first time, if this result is zero, explanation stake inner hole deposition slag thickness is more than or equal to reinforcing bar supporting leg 2 ride outs, need to change scouring bit and carry out hole processing clearly, then again detect; If this result is non-vanishing, and its difference can think that the sediment degree of depth meets code requirement during less than or equal to 5cm, and its difference must be changed scouring bit during greater than 5cm and carried out clearly the hole and process, and then again detects, until can carry out next procedure after meeting code requirement.Also can draw a hole depth when difference is non-vanishing as a result is h1+h2+h3, namely for the first time measurement result add reinforcing bar supporting leg 2 ride outs and disk 1 thickness and.The utility model structural principle is simple, and swift and convenient to operate effective, raw material are simple, and are economical and practical.
