Abstract
The utility model provides a settlement and deformation observing marker for a goaf railway. The marker comprises a bottom marker, a lengthening marker and a marker head, wherein the lengthening marker is arranged at the upper end of the bottom marker; and the marker head is arranged at the upper end of the lengthening marker. The lower part of the bottom marker is machined into a reversed-T shape, wherein the top part of the bottom marker is fixedly connected with a section of steel pipe; a screw thread is arranged inside the steel pipe; the external part of the steel pipe is machined into a hexagon shape. A screw thread is arranged at the bottom of the lengthening marker, wherein the top part of the lengthening marker is fixedly connected with a section of steel pipe; a screw thread is arranged inside the steel pipe; and the external part of the steel pipe is machined into a hexagon shape. The marker head is a section of stainless steel reinforcement, wherein a screw thread is arranged at the bottom of the marker head; the top part of the marker head is machined into a sphere shape; and the center of the sphere surface is engraved with a crossed engraved line. The settlement and deformation observing marker is simple in structure and convenient in operation and is applicable to a railway section in a settlement zone in which an observed marker requires to be heightened for multiple times as a goaf subgrade is heightened continuously. Therefore, the workload of field observation is reduced greatly, and the accuracy of settlement observation is ensured.
Description
Technical field
The utility model relates to a kind of observation monument, particularly a kind of survey mark that is used to monitor the railway sedimentation and deformation.
Background technology
For the ease of the protection and the maintenance of railway, need carry out the movement and deformation monitoring to the railway of above goaf, track measuring point and roadbed measuring point promptly are set along the railway, ask for railway movement and deformation value through observation, and with this basic data as line maintenance.Because the face of land constantly sank in long period; Railway bed must constantly be widened and increase, and can guarantee the safety traffic of train, and mostly traditional settlement observation sign is the concrete peg; The reinforcing bar that φ 16～φ 20mm is established in the centre indicates; Aperture with the sign top is the measuring point center, and mostly these observation monuments are the permanent observation monument fixed can not move or increase sign.Along with railway bed is increased and is widened, the high negative area behind the thick coal-layer mining particularly, measuring point will inevitably be embedded in underground, and is ineffective.As if former measuring point is increased or set up an office again temporarily, in practical application, there is more problem, bring certain difficulty to surveying work, not only increased the workload of observation, and accuracy of observation has also been had considerable influence.
Summary of the invention
The technical matters that the utility model will solve is: overcome deficiency of the prior art, a kind of survey mark that can increase continuously is provided.
The utility model provides a kind of goaf railway sedimentation and deformation observation monument, comprises bottom marker, adds long denotation and header, adds long denotation and is installed on the bottom marker upper end, and header is installed in and adds the long denotation upper end; Said bottom marker bottom is " ⊥ " shape, the affixed one section steel pipe in top, and the steel pipe inwall is provided with screw thread; External process becomes hexagon, and the said long denotation bottom that adds is provided with screw thread, the affixed one section steel pipe in top; The steel pipe inwall is provided with screw thread, and external process becomes hexagon, and said header is one section stainless steel rebar; The bottom is provided with screw thread, and sphere is processed at the top, and sphere centre is carved with the cruciform groove.
The utility model is simple in structure, and is easy to operate, is suitable for the goaf roadbed and continues to increase, needs Subsidence Area snipe that observation monument is repeatedly increased.Can significantly reduce the workload of fieldwork observation, guarantee the precision of settlement observation.

Fig. 4 indicates front view
Fig. 5 steel pipe vertical view
Among the figure, header 1 adds long denotation 2, steel pipe 3, bottom marker 4, screw thread 5, cruciform groove 6.
Embodiment
Like Fig. 1,2,3,4, the railway sedimentation and deformation observation monument of goaf shown in 5, comprise bottom marker 4, add long denotation 2 and header 1, add long denotation 2 and be loaded on bottom marker 4 upper ends, header 1 is loaded on and adds long denotation 2 upper ends; " ⊥ " shape is processed in said bottom marker 4 bottoms, the affixed one section steel pipe 3 in top, and the steel pipe inwall is provided with screw thread 5; External process becomes hexagon, and said long denotation 2 bottoms that add are provided with screw thread 5, the affixed one section steel pipe 3 in top; Steel pipe 3 inside are provided with screw thread 5, and external process becomes hexagon, and said header 1 is one section stainless steel rebar; The bottom is provided with screw thread 5, and sphere is processed at the top, and sphere centre is carved with cruciform groove 6.
During use, bottom marker 4 is embedded in concrete-pile top, and bottom marker 4 exposures are in the concrete column top; To indicate header 1 precession bottom marker 4 tops during observation, be that basic point is observed with the cruciform groove 6 on the header 1 top circular block, when roadbed need be increased; Take off header 1, will add long denotation 2 precession bottom markers 4 tops, again header 1 precession is added long denotation 2 tops; And measure the length that adds long denotation 2, handle in order to late time data.Cruciform groove 6 with on sign header 1 block is that basic point is observed.Along with roadbed continues to increase, add long denotation 2 adding can continue on the long denotation 2 to connect, promptly observation monument is extended piecemeal, to realize the long-term use of observation station, reduced the wasting of resources.
