Fig. 2 is the structural representation expanding body pick-up unit for the utricule in bellows enlarging anchor rod.
Embodiment
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the structural representation of bellows enlarging anchor rod, Fig. 2 is the structural representation expanding body pick-up unit for the utricule in bellows enlarging anchor rod, the utility model, expand body pick-up unit for the utricule in bellows enlarging anchor rod, comprise measure traverse line, two wire stiff ends, 5, two signal transmission wires (unmarked in figure), two measure traverse line receivers 4, conductor layers 2.
The inwall place at the place, certain maximum gauge line two ends that the utricule 100 that two wire stiff ends 5 are separately fixed at bellows enlarging anchor rod opens, the two ends of measure traverse line are separately fixed at two wire stiff ends 5, the length of measure traverse line etc. are longer than the design expansion head length of bellows enlarging anchor rod and are less than the maximum gauge length that utricule 100 opens, two signal transmission wires connect the two ends of measure traverse line respectively at two wire stiff end 5 places, and extend to ground, utricule 100 strut to measure traverse line be fully straightened and utricule 100 continues to strut time, the two ends of measure traverse line are easily pulled off.The inwall of utricule 100 is provided with conductor layer 2, signal transmission wire is arranged in conductor layer 2.
Two measure traverse line receivers 4 are arranged on utricule 100 inwall and panel towards utricule 100 center line is provided with opening, two wire stiff ends 5 lay respectively in two measure traverse line receivers 4, and measure traverse line to be accommodated in two measure traverse line receivers 4 and through two openings.
In the implementation case, measure traverse line comprises linear measure longimetry wire 3, two stressed measure traverse lines 1, and the two ends of linear measure longimetry wire 3 connect two stressed measure traverse lines, 1, two stressed measure traverse lines 1 respectively and are separately fixed at two wire stiff ends 5.
Linear measure longimetry wire 3 working strength is high, the material of poor ductility, not easily broken, for the measurement of utricule 100 opening dimension; Stressed measure traverse line 1 working strength is low, and the material of poor ductility is easily broken, opens back pull for responding to utricule 100, and after measure traverse line is straightened, stressed measure traverse line 1 is pulled off.
When utricule 100 is injected into mud, mud starts to pile up in utricule 100, utricule 100 struts by the mud piled up, and along with strutting of utricule 100, measure traverse line is also drawn out, because linear measure longimetry wire 3 adopts intensity high material, so this part wire is not easy to be pulled off, meanwhile, due to the poor ductility of linear measure longimetry wire 3, so the error of this wire stress and deformation on the direction of pulling force is less, within the scope of permission measuring error.It is larger that utricule 100 struts diameter, it is more that measure traverse line is drawn out, and measure traverse line is longer, when utricule 100 softened certain size, measure traverse line is completely pulled out of, stressed sensor wire 1 starts the effect of tension power, and utricule 100 continues softened, and pulling force continues to increase, because measure traverse line stressed sensor wire 1 intensity is little, the characteristic of poor ductility, this pulling force continued is pulled off this stressed sensor wire 1 soon, and now ground measuring equipment can detect that utricule 100 inside conductor disconnects.The disconnection of measure traverse line illustrates that the diameter dimension of mud accumulation cylinder has been greater than the length of measure traverse line, and the cylinder size of mud reaches engineering design requirements.If all there is not situation about disconnecting in measure traverse line always, then think that utricule 100 never struts predetermined value, illustrate that mud builds up formation right cylinder and do not reach standard in utricule simultaneously, utricule 100 in utricule anchor pole is not expanded successfully completely, mud does not form the cylindric of design needs yet, and in soil, utricule anchor pole does not form bolt action power shape, does not have anchor pole effect, now illustrate that rockbolt installation lost efficacy, and needed to carry out repair process and crossed, again construct.Use this device can judge the installation of anchor pole and whether successfully be in the milk, can be timely, find engineering problem fast, and solve in time.
Expand body detecting method for the utricule in bellows enlarging anchor rod, step comprises:
S1: utricule is expanded body pick-up unit and be assemblied in bellows enlarging anchor rod;
S2: check whether the measure traverse line in utricule connects intact;
S3: if measure traverse line connects normal, then continue operation S4; If measure traverse line malunion is normal, then again changes bellows enlarging anchor rod, again repeat S1-S3;
S4: note special grout according to calculating slurry amount in utricule, observe measure traverse line connection simultaneously;
S5: in the process pouring into cement, if measure traverse line disconnects, then stops grouting; If measure traverse line does not disconnect, then continue grouting, till measure traverse line disconnects;
Whether S6: the relation of length and grouting amount when disconnecting according to measure traverse line, calculate utricule and launch in reaming, judges whether expand body reaches design size.
In S2, operator first checked that whether the measure traverse line in utricule was intact before grouting, confirmed whether pick-up unit can normally work, and avoids the reason due to device to bring false judgment to operation; In S4-S6, in filling process, Real Time Observation measure traverse line is connection status or off-state, if measure traverse line keeps connection status always, illustrates that the diameter dimension of bladder deployment is less than test lead length by the mud piled up; If wire disconnects, illustrate that the diameter dimension of bladder deployment is greater than measure traverse line length by the mud piled up, when measure traverse line disconnects, the designing requirement of bladder deployment size conforms, this anchor pole enlarged footing reaches design specifications.
The utility model, according to the connection of measure traverse line in the filling process of enlarging anchor rod, judges whether mud is accumulated in utricule, and whether the right cylinder that in utricule, mud is formed reaches diameter dimension requirement during design; This structure of the detecting device is simple, easy to operate, has the advantages that to detect in real time, judges whether the installation of this anchor pole meets engine request in the process that can be in the milk again, improves construction quality, increases work efficiency.
Embodiment, only for technical conceive of the present utility model and feature are described, its object is to allow the personage being familiar with this art can understand the utility model content and be implemented, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
