Abstract
The utility model discloses a tunnel surface convergence observation station, and belongs to the surface deformation measuring equipment. The tunnel surface convergence observation station comprises an anchor bolt, a circular steel plate with holes, a rubber tube with fluorescent powder and a nut, wherein the circular steel plate with the holes is covered on the anchor bolt, the rubber tube with the fluorescent powder is covered on the anchor bolt and arranged above the circular steel plate with the holes, and the circular steel plate with the holes and the rubber tube with the fluorescent powder are fixed on the anchor rod through the nut. When the tunnel surface convergence being observed, the distance reduction of the bottom of the rubber tube with the fluorescent powder compared with the bottom distance of the rubber tube in the observation station is the real convergence of the surface between two surrounding rocks, the shortening distance of the rubber tube with the fluorescent powder reflects the deformation of the surrounding rocks above the anchoring base point. The tunnel surface convergence observation station has the advantages that the defect that a traditional short anchor bolt observation station is not capable of observing the deformation of the surrounding rocks above the anchoring base point is overcome, the rubber tube with fluorescent powder becomes more apparent in the underground dark environment, the phenomenon that the traditional observation station can not be found easily and be damaged is avoided, the rubber tube is elastic and soft, the operators can be prevented from being scratched by ledges of the anchor bolt in the observation station, the installation is easy, and economical and practical performances are good.
Description
Technical field
The utility model relates to a kind of Novel tunnel surface convergence survey station, metal surface deformation measuring device.Be particularly useful for the observation of mine working country rock surface convergence, also be applicable to the occasion that other needs the meter facial disfigurement.
Background technology
The roadway surrounding rock surface convergence is to carry out the ore deposit to press one of the most basic content of observation.The observed result of tunnel surface convergence reflects not only whether existing roadway support is rationally reliable, and can analyze the deformation rule of roadway surrounding rock under existing pressure state, for the construction of follow-up similar engineering provides reference, therefore, the accuracy of observation of tunnel surface convergence is extremely important to carrying out of roadway engineering.At present, the arrangement of tunnel surface convergence survey station mainly contains two kinds: a kind of for directly measuring basic point in the roadway surrounding rock surface markers, this method is simple, convenient, can measure the truly amount of shifting near on surface, tunnel, but because the roadway surrounding rock surface irregularity, and the multiple Mining procedure in down-hole, basic point is very easy to destroyed, particularly the surperficial country rock in surface whitewashing or basic point place comes off, and all may cause scrapping of survey station herein; Another kind is the short anchor pole about roadway surrounding rock superficial part installation length 800mm, expose about 100mm, basic point as the later stage measurement, this method survey station easily stays to be established, basic point is not easy to change the position, but the method anchor pole anchor pole is in the country rock of the tunnel interior surface 700mm degree of depth, during surrouding rock deformation beyond the 700mm, short anchor pole is not mobile, so this kind method can only be measured anchor point with the deflection of interior country rock, can not measure the in addition deflection of country rock of anchor point, and in the reality, the deflection of tunnel superficial part country rock is obvious than the deep, is the emphasis of observation.
Summary of the invention
In view of the deficiency that prior art exists, that the purpose of this utility model provides is effective, easy construction, good in economic efficiency a kind of tunnel surface convergence survey station.
The utility model solves the used technical scheme of its technical problem: a kind of tunnel surface convergence survey station, and it comprises anchor pole, circular steel plate with holes, with rubber tube and the nut of fluorescent material; Described circle steel plate with holes is sleeved on the anchor pole, is the rubber tube with fluorescent material that is sleeved on the anchor pole above it, circular steel plate with holes and be fixed on the anchor pole with nut with the rubber tube of fluorescent material.
But thickness 13mm, 14mm, 15mm or the 16mm of described circle steel plate with holes; Diameter is 50mm, 100mm, 150mm or 200mm.
Described rubber tube external diameter with fluorescent material is 30mm, 40mm or 50mm, and length is 40mm, 50mm, 60mm or 70mm; Selected according to site operation anchor pole protruded length and rock property.
Described with the adding in the rubber tube casting of the fluorescent material in the rubber tube of fluorescent material; Or at rubber tube moulding rear surface spary phosphor powder layer.
This survey station is placed with the anchor pole insertion in the bolthole of resin explosive roll first, when mounted with 0.25m around the anchor pole
2The country rock surface preparation smooth, then steel plate with holes is installed, make steel plate be close to the country rock surface, the rubber tube of last mounting strap fluorescent material, fastening nut.This survey station when measuring, with the bottom of fluorescent material rubber tube apart from relative survey station rubber tube bottom be the truly amount of shifting near between two country rock surfaces apart from decrease, react the deflection of the above country rock of anchor rod anchored basic point with the shortening amount of the rubber tube of fluorescent material.
The beneficial effects of the utility model are: the utility model designs for accurately measuring the tunnel surface convergence specially.Well solve traditional short anchor pole survey station and can't measure the shortcoming of the above rock deformation of anchoring basic point; Under the dim environment in down-hole, more eye-catching with the rubber tube of fluorescent material, avoid traditional survey station because being not easy to find destroyed phenomenon; Because the rubber tube band is flexible, softer, can prevent that the workman is by the abrasive danger of survey station anchor pole ledge.This Novel tunnel surface convergence survey station is installed simply, and is economical and practical, and good application value is arranged.
Description of drawings
Fig. 1 is the sectional drawing of a kind of Novel tunnel surface convergence of the utility model survey station.
Fig. 2 is the working drawing of a kind of Novel tunnel surface convergence of the utility model survey station
Among the figure: 1-is with the rubber tube of fluorescent material, the circular steel plate with holes of 2-, and the 3-nut, the 4-anchor pole, rock stratum beyond the 5-anchoring basic point, 6-anchor point, the 7-anchor point is with interior rock stratum, the 8-tunnel.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of tunnel surface convergence survey station, this survey station are by short anchor pole 4, circular steel plate 2 with holes, form with rubber tube 1, the nut 3 of fluorescent material.Circular steel plate 2 with holes is sleeved on the short anchor pole 4, is the rubber tube 1 with fluorescent material that is sleeved on the short anchor pole 4 above it, circular steel plate 2 with holes and be fixed on the short anchor pole 4 with the rubber tube 1 usefulness nut 3 of fluorescent material.But thickness 13mm, 14mm, 15mm or the 16mm of circular steel plate with holes; Diameter is 50mm, 100mm, 150mm or 200mm, and actual roadway surrounding rock character and site operation situation are selected.Rubber tube external diameter with fluorescent material is 30mm, 40mm or 50mm, and length is 40mm, 50mm, 60mm or 70mm; Selected according to site operation anchor pole protruded length and rock property.With the fluorescent material the present embodiment in the rubber tube of fluorescent material at rubber tube moulding rear surface spary phosphor powder layer.
