Description

Accurately crack vertical strain monitoring device

Technical field

The utility model is related to a kind of instruments being monitored to ground fissure deformation.

Background technology

Ground fissure can form the crack of certain length and width as a kind of geological disaster on ground, to engineering construction and Personal safety causes great harm, it is therefore desirable to carry out long term monitoring to it.The simple monitoring device of ground fissure is as a kind of solid It is scheduled on the ground fissure three-dimensional activity monitoring device at ground fissure scene, the vertical deformation, horizontal tension and water of ground fissure can be measured It heaves dynamic variable quantity, has many advantages, such as that easy to operate, space is limited, monitoring result visual pattern.

But the simple monitoring device of common ground fissure can not directly display the variation magnitude of ground fissure deformation, need people Work can all influence measurement accuracy using vernier caliper in-site measurement however, due to the difference of the position and angle that measure every time, So that monitoring data error is increased, the requirement on monitoring accuracy cannot be met.

Utility model content

The purpose of this utility model is that：A kind of accurately crack vertical strain monitoring device is provided, existing skill is solved Above-mentioned technical problem present in art.

To achieve the above object, the technical solution adopted in the utility model is：

A kind of accurately crack vertical strain monitoring device, includes the crossbeam arranged along horizontal cross, in the crossbeam There is the cutting of zigzag to stitch in portion, and be divided into two sections of one section of monitoring and monitoring, it is characterised in that：

It fixes there are one the main scale vertically arranged in one section of tip position of monitoring, is connected with sliding block on the main scale One can be relative to the auxiliary scale that main scale vertically moves, and the main scale is equipped with the evenly divided of different indexing from auxiliary scale, with structure At vernier caliper；

The auxiliary scale is also connected by a transverse sliding mechanism with a longitudinal sliding motion mechanism with two sections of the monitoring.

The accurately crack vertical strain monitoring device, wherein：The zero graduation line of the main scale and the monitoring one The upper plane of section is concordant, other graduation marks on main scale are arranged in order downwards.

The accurately crack vertical strain monitoring device, wherein：Longitudinal sliding motion track, institute are fixed in the auxiliary scale State two sections of monitoring and be equipped with and slide laterally track, a slider bar be connected to the longitudinal sliding motion track with slide laterally track it Between, and the slider bar can either along longitudinal direction be slided with respect to auxiliary scale, and opposite can monitor two sections and transversely slide.

The accurately crack vertical strain monitoring device, wherein：Crack both sides on the ground are respectively provided with one and bury Deep is more than the steel reinforcement cage of frozen soil layer, and the crossbeam, the both ends of the crossbeam and the steel reinforcement cage are fixed between two steel reinforcement cages It is poured and is integrated by cement.

Compared with prior art, it is had the advantage that using the utility model of above-mentioned technical proposal：It can be direct It shows ground fissure vertical deformation amount, while offsetting the deflection of tension deformation and the horizontal changing of the relative positions using sliding equipment, measurement is made to fill Set is not influenced in ground fissure 3 D deformation by tension deformation and the horizontal changing of the relative positions, and only measures vertical deformation amount, is realized and is reduced Measurement error improves the purpose of measurement accuracy.

Specific implementation mode

As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of accurately crack vertical strain monitoring device, be Crack both sides on ground are respectively provided with the steel reinforcement cage (being unillustrated) that a buried depth is more than frozen soil layer, are fixed between two steel reinforcement cages There are a crossbeam, the crossbeam to pass through level correction, both ends, which pour to be integrated by cement with the steel reinforcement cage, (is known as pier 1)；It is cut open in the middle part of the crossbeam, forms the cutting seam 2 of zigzag, in order to measure the three-dimension deformation-quantity of ground fissure, this For the prior art.

In order to express easily, the axial direction of the crossbeam is referred to as lateral, is longitudinal with lateral vertical horizontal direction；The cross It is divided into monitoring after beam cutting to be under normal circumstances lifted one section of 3 setting of the monitoring in ground fissure with two section 4 of monitoring for one section 3 End, and two section of 4 setting of the monitoring declines end in ground fissure；

As shown in Figure 1, Figure 2, Figure 3 shows, the utility model is to fix that there are one vertically cloth in the tip position of one section 3 of monitoring The main scale 5 set, with the connection of sliding block 6, there are one can be relative to the auxiliary scale 7 that main scale 5 vertically moves, the main scale on the main scale 5 5 are equipped with the evenly divided of different indexing from auxiliary scale 7, to constitute vernier caliper；In the case of preferably, zero quarter of the main scale 5 It is concordant with the upper plane for monitoring one section 3 to spend line, other graduation marks are arranged in order downwards；

The auxiliary scale 7 is also connected for two section 4 by a transverse sliding mechanism with a longitudinal sliding motion mechanism with the monitoring, The transverse sliding mechanism and the sequencing of longitudinal sliding motion mechanism are unlimited；In the present embodiment, it is fixed in the auxiliary scale 7 vertical To sliding rail 8, the monitoring is equipped with for two section 4 and slides laterally track 9, and a slider bar 10 is connected to the longitudinal sliding motion rail Road 8 and between sliding laterally track 9, and the slider bar 10 can either along longitudinal direction be slided with respect to auxiliary scale 7, and being capable of opposite prison It surveys two section 4 and transversely slides；

So set, once due to the deformation of ground fissure so that monitoring is stitched for two section 4 for one section 3 in cutting with monitoring and generated at 2 Vertical strain, then auxiliary scale 7 is understood generate onesize and direction vertical strain with respect to main scale 5, and can be light on vernier caliper Reading of changing places obtains, moreover, because reading is measured using same measurer in same position every time, measurement accuracy obtains It ensures.

And if also creating transverse deformation and/or longitudinal deformation at cutting seam 2, these deformation will all be slid laterally Mechanism and/or longitudinal sliding motion mechanism are prevented, and the measurement of vertical strain can't be influenced.

It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art Understand, in the case where not departing from spirit and scope defined by claim, can many modifications may be made, variation or it is equivalent, but It falls within the scope of protection of the utility model.
