Abstract
The utility model relates to a novel slip casting stock of taking scale is by clamping ring installs tip outside the slip casting stock, include to let press and manage, let the middle part of pressing the pipe establish to outside expanded spherical structure, just let and press the yield strength who manages to be less than the tensile strength of stock, let the both ends of pressing the pipe connect the bearing pad board respectively, the center of bearing pad board corresponds lets the mouth of pipe of pressing the pipe be equipped with the through -hole, let the one side of pressing the pipe be equipped with and be used for showing and let the scale and the pointer of pressing the pipe deflection, should let the clamping ring all can carry out the deformation monitoring to all sectional slip casting points in tunnel, convenient operation, it is directly perceived, to every sectional slip casting opportunity definitely having a great directive significance.
Description
Technical field
The utility model relates to a kind of novel grouted anchor bar (rope) allows laminated structure, and the grouted anchor bar being specially a kind of Novel belt scale, by pressure ring, belongs to Mineral Engineering field.
Background technology
Traditional grouting method installs grouted anchor bar (rope) at roadway surrounding rock after excavating tunnel, then rule of thumb wait for a period of time (as 15 ~ 18 after tunnelling day), after roadway surrounding rock inside produces more crack, carry out grouting and reinforcing again.
The method tool that this time for injecting is selected bears the character of much blindness.First, the distortion of roadway surrounding rock has the feature such as inhomogeneities, asymmetry, and the distortion of the left side of same drift section and right side often has larger difference, and along tunnel, axial different section distortion also exists larger difference; Secondly, the deformation failure time of adjacent drift section often has and has asynchronism, and its best grouting and reinforcing is not identical for opportunity yet.Therefore, it is obviously unscientific for unifying grouting and reinforcing according to the data of a small amount of drift section deformation monitoring and previous experiences to whole piece tunnel.But if all carry out deformation monitoring to each section in tunnel, then according to the deformation slip casting respectively of each section, workload is too large, and feasibility is not high.
Utility model content
For above-mentioned prior art Problems existing, the utility model provides a kind of finger slip casting with drift section deformation monitoring function allow pressure ring, has directive significance directly perceived to the selection of time for injecting.
The utility model is achieved through the following technical solutions: a kind of grouted anchor bar of Novel belt scale is by pressure ring, be arranged on grouted anchor bar outer end, comprise and allow pressure pipe, allow the middle part of pressure pipe be set to the spherical structure outwards expanded, and allow the yield strength of pressure pipe be less than the tensile strength of anchor pole; The described two ends of pressure pipe that allow connect Pressure-bearing pads respectively, and the center correspondence of Pressure-bearing pads allows the mouth of pipe of pressure pipe be provided with through hole; Allow the side of pressure pipe be provided with and allow the scale of pressure pipe deflection and pointer for showing.
The outer rim correspondence of described two Pressure-bearing pads is provided with metal sheet and the scale base of extension, and one end and the scale base of scale are connected, and the other end is through the pilot hole on metal sheet, and on metal sheet, corresponding scale is provided with pointer.
Described scale one end is fixed on scale base by welding or bonding mode.
Described Pressure-bearing pads is circular plate-like shape structure, the aperture of its through hole with make the aperture of pressure pipe two-port consistent.
The described pressure pipe that allows is formed by metal tube compacting.
The beneficial effects of the utility model: all can carry out deformation monitoring to the slip casting point of all sections in tunnel, easy to operate, intuitively, great directive significance is defined to the time for injecting of each section.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, a kind of grouted anchor bar of Novel belt scale, by pressure ring, is arranged on grouted anchor bar outer end, comprises allowing pressure pipe 2, allows the middle part of pressure pipe 2 be set to the spherical structure outwards expanded, and allows the yield strength of pressure pipe 2 be less than the tensile strength of anchor pole 10; The described two ends of pressure pipe 2 that allow connect Pressure-bearing pads 1 respectively, and the center correspondence of Pressure-bearing pads 1 allows the mouth of pipe of pressure pipe 2 be provided with through hole; Allow the side of pressure pipe 2 be provided with and allow the scale 4 of pressure pipe 2 deflection and pointer 7 for showing.
The outer rim correspondence of described two Pressure-bearing pads 1 is provided with metal sheet 5 and the scale base 3 of extension, and one end and the scale base 3 of scale 4 are connected, and the other end is through the pilot hole 6 on metal sheet 5, and on metal sheet 5, corresponding scale 4 is provided with pointer 7.
Described scale 4 one end is fixed on scale base 3 by welding or bonding mode.
Described Pressure-bearing pads 1 is circular plate-like shape structure, the aperture of its through hole with make the aperture of pressure pipe 2 two-port consistent.
The described pressure pipe 2 that allows is formed by metal tube compacting.
Operating principle of the present utility model: after tunnelling, first install grouted anchor bar 10 by the arrangement punching designed, the mounting means of grouted anchor bar 10 as shown in Figure 3.Pressure ring will be allowed to install between locking nut 8 and pallet 9; After bolt-spary supports, roadway surrounding rock deforms under geostatic stress effect, due to the tensile strength allowing the yield strength of pressure pipe 2 be less than anchor rod body, pressure pipe 2 is allowed first to be compressed, at this moment the rock deformation of corresponding scale 4 display is read by pointer 7, when rock deformation reaches the deformation values corresponding to reasonable time for injecting, grouting and reinforcing is carried out to country rock within the scope of the anchoring of this grouted anchor bar, realize the independent control to every root grouted anchor bar time for injecting, improve the grouting consolidation effect of roadway surrounding rock bolt-grouting support.The utility model is equally applicable to anchor cable.
