Description
Technical field
The present invention relates to soil test field, more relate to a kind of for screw plate test instrument dowel bar pull-up, screw plate test can be terminated rear dowel bar and extract ground quickly and easily.
Background technology
Screw plate test is the plate evolving development of nearly 30 years cause routines and comes, and is in-situ testing technique most widely used at present.Screw plate test a spiral bearing plate (hereinafter referred to as spiral plate) is used manpower or mechanical force revolves the predetermined test degree of depth of people's below ground, by dowel bar to spiral plate load application, the resistance strain type sensor be connected with spiral plate by dowel bar lower end surveys the load read spiral plate and bear, corresponding deformation when bearing different load by observing the distortion of dowel bar be connected from spiral plate survey reading spiral plate, pass through obtained stress one and be out of shape a time curve, ask for the bearing capacity of foundation soil, modulus of deformation, the design parameterss such as the coefficient of consolidation and saturated soft clay undrained shear strength.
After spiral plate off-test, general pipe grippers relies on manpower one to save and is extracted by dowel bar at leisure, such one side takes manpower very much, also very time-consuming on the other hand, cause test efficiency low, therefore, in order to overcome the above problems, be badly in need of development a kind of for spiral load test instrument dowel bar pull-up, use convenient laborsaving, improve testing efficiency.
Summary of the invention
The object of the invention is to there are provided one for spiral load test instrument dowel bar pull-up, structure is simple, easy to use, this device can be extracted after spiral load off-test a section for dowel bar easily fast, not only convenient laborsaving but also improve testing efficiency, solve because manpower works the problem that wastes time and energy of pulling out screw plate test instrument dowel bar, quickly and easily dowel bar can be extracted, improve test efficiency; Rising of cone penetration test sounding rod can also be applicable to pull out.
In order to realize above-mentioned object, the present invention adopts following technical measures:
A kind of for spiral load test instrument dowel bar pull-up, comprise dowel bar, dowel bar joint and base, it is characterized in that: connected by dowel bar joint between the first dowel bar and the second dowel bar, dowel bar joint both sides are provided with square orifice; Be arranged on the first fluctuating orbit below base, the second fluctuating orbit, crane and rise and pull out arm, first fluctuating orbit, the second fluctuating orbit be opening in opposite directions, the channel-section steel that is parallel to each other, and being vertically connected on base, the first fluctuating orbit, the second fluctuating orbit are connected by back timber; The roller of crane is arranged in the first fluctuating orbit, the second fluctuating orbit and can moving up and down along the first fluctuating orbit, the second fluctuating orbit, rises to pull out arm and be fixed on crane; Be provided with top sheave and hoisting cable anchorage ear below back timber, crane top is provided with lower sheave, and be provided with wireline winch in the middle part of the first fluctuating orbit, the second fluctuating orbit, wireline winch is provided with wind; Wire rope one end is fixed on hoisting cable anchorage ear, and the other end is walked around after lower sheave, top sheave successively around on wireline winch.
Advantage of the present invention and there is effect:
1. the invention solves because manpower works the problem that wastes time and energy of pulling out screw plate test instrument dowel bar, ensure that and the power transmission of screw plate test instrument is extracted time saving and energy savingly.
2. structure of the present invention is simple, light, can be extracted by dowel bar quickly and easily, improve test efficiency.

Detailed description of the invention
Embodiment 1:
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1 and Figure 2, a kind of for spiral load test instrument dowel bar pull-up, comprise dowel bar 1, dowel bar joint 2 and base 3, it is characterized in that: connected by dowel bar joint 2 between the first dowel bar 1a and the second dowel bar 1b, dowel bar joint 2 both sides are provided with square orifice; Be arranged on the first fluctuating orbit 4a below base 3, the second fluctuating orbit 4b, crane 6 and rise and pull out arm 7, first fluctuating orbit 4a, the second fluctuating orbit 4b be opening in opposite directions, the channel-section steel that is parallel to each other, and being vertically connected on base 3, the first fluctuating orbit 4a, the second fluctuating orbit 4b are connected by back timber 5; The roller of crane 6 is arranged in the first fluctuating orbit 4a, the second fluctuating orbit 4b and can moves up and down along the first fluctuating orbit 4a, the second fluctuating orbit 4b, rises and pulls out arm 7 and be fixed on crane 6; Be provided with top sheave 12 and hoisting cable anchorage ear 11 below back timber 5, crane 6 top is provided with lower sheave 13, and be provided with wireline winch 8 in the middle part of the first fluctuating orbit 4a, the second fluctuating orbit 4b, wireline winch 8 is provided with wind 9; Wire rope 10 one end is fixed on hoisting cable anchorage ear 11, and the other end is walked around after lower sheave 13, top sheave 12 successively around on wireline winch 8.
During work, steel wire winch 8 is driven to rotate by wind 9, wire rope 10 is progressively coiled on wireline winch 8, lower sheave 13 is moved upward by wire rope 10 traction, and crane 6 moves upward with lower sheave 13, pulls out the square opening that arm 7 directly inserts dowel bar joint 2 both sides, rise and pull out arm 7 and promoted with crane 6, thus the first dowel bar 1a is progressively pulled out, when the dowel bar joint 2 of dowel bar 1a bottom is when extracting ground, can stop pulling out; By pipe grippers, second section dowel bar 1b is fixed, utilize pipe grippers to be laid down by the dowel bar 1a extracted, allowed and pulled out the dowel bar joint 2 that arm 7 inserts dowel bar 1b top, successively the first dowel bar 1a and the second dowel bar 1b is extracted according to aforesaid operations step.
