After the stock gets into the operation state, along with supporting the not hard up of the outside country rock of section, can drive the end movement of baffle towards early warning device to make to support section and anchor section part each other, at the detached in -process, the early warning line surpasss the length of rock mass can be shorter and shorter, consequently, and the stress of the length situation judgement stock that measurement personnel can be through early warning indicating line, taking precautions againt calamity. This early warning device's simple structure, simple to operate.
Description
Technical field
The utility model belongs to the technical field of foundation stabilization, and in particular to a kind of prior-warning device of anchor pole.
Background technology
Anchor rod anchored is a kind of reinforcing mode for being in the earth formation tightly chained together works and stratum by anchor pole,
The pulling force of anchor pole and the shearing strength transferring structure thing of surrounding formation is relied in work, stratum itself is reinforced, guarantor is reached
Hold the purpose of works and Rock Slide Stability.Anchor pole can be divided into tension type anchor pole and pressure according to the stress state difference residing for anchoring piece
Power type anchor pole.Tension type anchor pole is easily pulled off when working, and the stability and antiseptic property of pulling force firmware are all poor.And pressure-type
The bearing capacity and deformation performance of anchor pole make moderate progress compared with tension type anchor pole, have for permanent anchoring engineering very big excellent
More property.
After anchor bolt construction is finished, due to burying the reason being trapped in rock mass, the working condition and compression situation of anchor pole are extraneous
It is difficult to detect, this is very big threat to the safety during operation.Therefore, need badly and a kind of facilitate testing staff to judge anchor pole
Working condition prior-warning device.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of prior-warning device for anchor pole, the prior-warning device
Simple structure, and facilitate testing staff to observe and take appropriate measures.
The technical scheme that the utility model solution above-mentioned technical problem is used is for a kind of prior-warning device of anchor pole, institute
Anchor pole is stated including anchoring section and section is supported, connection anchoring section is provided with the anchoring section and between supporting section and is supported the early warning of section
Device；The prior-warning device includes the dividing plate that can be slided along prior-warning device inwall；The dividing plate side and anchoring section or support section
Connection, early warning line is connected near the side of section is supported；The early warning line is extended to along support section and stretched out outside rock mass.
After anchor pole enters operation state, with the loosening for supporting section outside country rock, can be filled towards early warning with dynamic dividing plate
One end movement put, so that support that section and anchoring section are separated from each other, in a separate process, length of the early warning line beyond rock mass
Can it is shorter and shorter, therefore, testing staff can judge the stress of anchor pole by the length situation of early warning instruction line, prevent in
Possible trouble.The simple structure of the prior-warning device, it is easy for installation.
Further, the side being connected with anchoring section on the dividing plate or the side being connected with support section are provided with and early warning
The elastomeric element of crust of the device connection.The elastomeric element can be anchoring section and support section as the main bearing member of anchor pole
Offer holdback force is separated from each other, so as to strengthen the bearing capacity and deformability of anchor pole.
Further, the elastomeric element is stage clip.It is not easy to crack when stage clip is in pressured state, for permanent anchoring work
Journey tool has an enormous advantage.
Further, when the side of the dividing plate is connected with anchoring section, the anchoring section sets with the junction of prior-warning device
There is chute；When the side of the dividing plate is with supporting that section is connected, the support section is provided with chute with the junction of prior-warning device.It is logical
Cross setting chute, it is possible to decrease support section or the frictional force between anchoring section and prior-warning device, prevent the Housing failure of prior-warning device,
Extend the service life of prior-warning device.
Further, the top for supporting section is socketed with anchor disk and nut successively.
Further, the support section is provided with axial through hole, and the early warning line is laid along the through hole and stretches out support
Outside section.It is placed within support section by by early warning line, is not only advantageous for maintenance, detection and the installation of early warning line, and this
Bolt deformation degree shown by early warning line under state is more accurate.
Further, the early warning line is welded or is bonded as one with dividing plate.Which kind of combined process is specifically used, can be according to pre-
Depending on the material of alert line and dividing plate, for example, when early warning line and dividing plate are stainless steel, using the early warning line of solder bond
Adhesion with dividing plate is stronger, and testing result is more effectively.Further, the early warning line is stainless steel wire.
