Abstract
Disclosed is a displacement meter anchoring cartridge for monitoring the displacement of a rock mass, which relates to a displacement meter anchoring cartridge for multi-aspect, wide-range and high precision displacement measurement applied to geotechnical engineering such as mine, railroad, water conservancy and military. The displacement meter anchoring cartridge is characterized in that: the structure of the anchoring cartridge comprises a displacement transferring steel wire which is a core shape long steel wire, and one end thereof is connected with the displacement meter; a displacement transferring steel wire bushing is a hollow pipe body nested with the displacement transferring steel wire; a woody compressed body is a tubular compressed wood nested on the displacement transferring steel wire bushing for fixing the anchoring cartridge, and the two ends thereof are located and fixed by a ring shape positioning body nested on the displacement transferring steel wire bushing; and a displacement transferring steel wire head fixed block is fixed in the displacement transferring steel wire bushing by a screw penetrating through the ring shape positioning body at the far end of the woody compressed body for fixing the anchoring cartridge, and is in screwed joint with the displacement transferring steel wire head. The displacement meter anchoring cartridge has the advantages of novel structure, simple operation and reliable performance, and can implement the multi-aspect, wide-range and high precision displacement monitoring.
Description
Technical field
A kind of displacement meter anchorage head of monitoring rock displacement, relate to a kind of be applicable to mine, railway, water conservancy, military isolith geotechnique journey multi-faceted, on a large scale, the displacement meter anchorage head that measures of high precision displacement.
Background technology
At present, in the mine, railway, water conservancy, military isolith geotechnique Cheng Yanti internal displacement monitoring instrument adopt the anchoring of grouting formula, fluid pressure type mostly, cost height, precision are not high, cause and have defective when using, and complicated operation, monitoring effect are not good, fail to realize multi-faceted, on a large scale, high precision monitor.
Summary of the invention
The purpose of this utility model is to adopt the anchor block of grouting formula, fluid pressure type at rock mass internal displacement monitoring displacement meter in the Geotechnical Engineering, cost height, precision are not high, use situations such as complicated, that monitoring effect is not good, the displacement meter anchorage head of the monitoring rock displacement of a kind of simple to operate, dependable performance, novel structure is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of displacement meter anchorage head of monitoring rock displacement is characterized in that its structure comprises:
It is the long steel wire of a rope type that steel wire-this steel wire is transmitted in displacement, and an end connects with displacement meter;
It is one to be set with the hollow body that steel wire is transmitted in displacement that steel wire casing-this sleeve pipe is transmitted in displacement;
Fixedly the wooden compression body of anchorage head-this wooden compression body is transmitted steel wire casing for tubular compression wood is sleeved on displacement, and two ends are by the circle type positioning body positioning and fixing that is sleeved on the displacement transmission steel wire casing;
Displacement is transmitted steel wire head fixed block-this fixed block and is passed the screw retention of the fixing circle type positioning body of the wooden compression body far-end of anchorage head in steel wire casing is transmitted in displacement, with displacement transmission steel wire head thread connection by one.
A kind of displacement meter anchorage head of monitoring rock displacement of the present utility model contacts main body with rock mass, be positioned at and go deep into the head in test point position, fixedly the wooden compression body chance water of anchorage head then expands, be fixed on the petrosal foramen of test, novel structure, simple to operate, the advantage of dependable performance, can generally be applicable to mine, railway, water conservancy, military isolith geotechnique Cheng Yanti inside multi-faceted, on a large scale, high-precision displacement monitoring.

Embodiment
A kind of displacement meter anchorage head of monitoring rock displacement is characterized in that its structure comprises:
It is the long steel wire of a rope type that this steel wire of steel wire 1-is transmitted in displacement, and an end connects with displacement meter;
It is one to be set with the hollow body that steel wire is transmitted in displacement that this sleeve pipe of steel wire casing 2-is transmitted in displacement;
Fixedly this wooden compression body of the wooden compression body 3-of anchorage head is transmitted steel wire casing for tubular compression wood is sleeved on displacement, and two ends are by circle type positioning body 6 positioning and fixing that are sleeved on the displacement transmission steel wire casing;
Displacement is transmitted this fixed block of steel wire head fixed block 4-and is passed fixedly the screw 5 of the circle type positioning body 7 of the wooden compression body far-end of anchorage head by one and be fixed in displacement and transmit in the steel wire casing, with displacement transmission steel wire head thread connection.
The utility model displacement meter anchorage head relies on compressed wood to be fixed on precalculated position in the boring, and after the immersion, compressed wood produces one-sided expansion within a certain period of time and forms anchor force, with boring crag jam-packed, constitutes measuring point in the instrument; Internal and external casing has guaranteed that measuring steel wire has the good space that is free to slide, and connects measuring point in each hole simultaneously.Boring can be measured after installing and treating that anchor point is stable.
