Description
Technical field
the utility model relates to anti-float anchor rod pull-out test device technique field in construction work, particularly a kind of anti-floats request anchor rod drawing test instrument.
Background technology
Anti-float anchor rod, is also anti-floating pile, is the one of construction work underground structure measure of anti float.Anti-float anchor rod is different from general foundation pile, have the special performance of himself, be with the maximum difference of general foundation pile: foundation pile is generally compressive pile, pile body bears built-loading pressure, stressedly transmit at the bottom of stake from stake top, the stressed size of pile body changes along with the change of built-loading; And anti-floating pile is resistance to plucking, pile body bears pulling force, and common anti-floating pile is stressed is also transmit at the bottom of stake from stake top, and the stressed size of pile body changes along with the change of groundwater table, but both mechanical behaviors are just the opposite.
At the buoyancy that deep foundation ditch is the generation of opposing underground water, usually need to arrange anti-float anchor rod, wherein, one group of dowel that anti-float anchor rod generally adopts 1-4 root Φ 22-32 to form.The loading test test of anti-float anchor rod all utilizes punching jack to carry out on-the-spot pull-out test, in traditional pull-out test, will punching jack through whole group of dowel, then at dowel upper weld one section of reinforcement bar, thus jack power is upwards delivered on dowel, there is Railway Project in this kind of mode: 1, when dowel 3-4 root, must use bigbore jack, otherwise punching is worn to pass by; 2, for guaranteeing that test can be carried out, the length that dowel bassets must reach more than 1.5m, otherwise must be welded with reinforcing bar spreading, compares waste; 3, when the dowel basseted is very long or some is bending, punching is very hard, affects efficiency; 4, often doing battery of tests all will wait reinforcement bar freeze up and cool, and loses time, affects efficiency.
Chinese patent CN203908864U discloses a kind of Simple tunnel anchor rod drawing kit, wherein, anchor pole does not need reserved very long, do not need welding to lengthen even if too short yet, this kit comprises the female adapter sleeve of tool and one section of lengthening anchor pole, the external part of anchor pole is provided with connecting thread and is threaded togather with adapter sleeve, the one end lengthening anchor pole is also provided with connecting thread and is threaded togather with adapter sleeve, by adapter sleeve and lengthening anchor pole, anchor pole is extended, then load, but this kind of mode is when being only applicable to single dowel, and the external part of dowel also needs to be provided with the screw thread consistent with adapter sleeve specification in advance, poor for applicability.
Chinese patent CN203229975U discloses a kind of tendon anchoring grip device, this device improve reinforcing bar in traditional experiment freeze time-consuming and waste problem, still there is other several shortcoming: when 1, the reinforcing bar of tendon is many, small-bore jack is worn to pass by; 2, dowel must basset very long, otherwise must be welded with reinforcing bar spreading, and expense of taking a lot of work is expected; 3, when the dowel basseted is very long or some is bending, punching is hard, affects efficiency.
