Description

Ground Crack Measuring Device

technical field

The utility model relates to the technical field of geological surveying devices, in particular to a ground crack measuring device.

Background technique

Ground cracks are a geological phenomenon in which surface rocks and soils crack under the action of natural or human factors, and form cracks of a certain length and width on the ground. When this phenomenon occurs in areas with human activities, it can be become a geological disaster. Therefore, mastering its changing trend is an important basis for engineers and technicians to take corresponding preventive measures in time. Generally speaking, the deformation of geological fractures is three-dimensional, especially in the X-axis and Z-axis, that is, the lateral tension closure, and the vertical settlement displacement deformation are particularly important. At present, there are many methods and devices for monitoring or measuring geological fractures. For example, the new technology uses GPS to monitor the deformation of the monitoring points on both sides of the fracture, but the measurement accuracy is affected by factors such as satellite signals and weather, and the cost of such equipment is relatively high. Conducive to promotion and application. Existing mechanical measuring devices are also widely used. Generally, more precise instruments are required for measurement. The instruments are stored in the field for a long time, are easily damaged, and the cost is also high.

The patent document with the Chinese notification number CN207963859U discloses a ground crack measurement device, which provides a ground crack measurement device, including a distance measuring tube, a sight distance tube, an angle measuring tube, a positioning tube, a fixed rod, a base and a movable seat The distance tube is sleeved on the distance measuring tube, the distance tube is provided with an observation window, the two sides of the observation window are provided with a displacement scale, and the end of the distance tube away from the distance measuring tube is provided with an inclination scale; the distance tube and the positioning The barrels are respectively connected with the bearings arranged at both ends of the angle measuring barrel. The angle measuring barrel is provided with a swing groove, and a rotating shaft is arranged in the swing groove. A dial is arranged on one side of the top of the swing groove, and an elevation scale is arranged on the edge of the dial. The measuring tube is provided with a scale line at one end of the sight tube; a connecting rod is movably connected on the rotating shaft, the top of the connecting rod is provided with a pointer, and the bottom end of the connecting rod is fixedly connected with a counterweight ball. In the above solution, when the ground on both sides of the crack subsides, the distance measuring cylinder rotates, and the pointer is always kept vertical under the action of the counterweight ball, so that the pointer points to different scales, and feedbacks the height difference of the bottom surface on both sides of the crack.

In the above scheme, when the bottom surface on both sides of the crack subsides, the distance measuring cylinder will rotate, and the horizontal horizontal length of the distance measuring cylinder will be shortened at this time, that is to say, the distance between the brackets on both sides of the distance measuring cylinder will be reduced. shorten, so the bracket will slide on the ground, and the distance between the two brackets will be tightened, which will likely cause the entire device to fall during the movement of the bracket. If the brackets are firmly fixed on the ground and the distance between the brackets does not change, the ranging tube will not be able to rotate, and the settlement of the crack cannot be measured. Due to the change of the crack, the mutual containment of the bracket and the ranging tube is also easy. Causing the entire device to fall or be damaged.

Utility model content

The utility model intends to provide a ground crack measuring device to solve the problem that the measuring device is prone to fall when the ground crack changes.

In order to achieve the above object, the basic scheme of the present utility model is as follows:

Beneficial effects of the basic scheme: (1) In this scheme, the first bracket and the second bracket are respectively fixed on both sides of the crack. When the ground on both sides of the crack subsides, the first bracket or the second bracket will be raised accordingly Move or move down, so that the slide bar slides in the collar, and by observing the scale on the corresponding slide bar at the collar, the settlement of the ground on both sides of the crack can be known. Compared with the rotation method of the measuring cylinder in the prior art, when the ground on both sides of the crack subsides in this scheme, the two supports will only be displaced in height due to the settlement, and will not be affected by the horizontal direction , so as to ensure the stability of the whole device and the accuracy of the measurement data.

(2) In this solution, a telescopic rod is used between the two brackets, which can effectively adapt to the change of the crack width, and avoid the two brackets being pulled due to the change of the crack width, resulting in accidents such as dumping.

Further, it also includes a buzzer and a power supply. The ends of the two poles close to the slide bar are fixed with touch switches, and the two touch switches are arranged opposite to each other. The two touch switches are connected to the power supply and the buzzer. The buzzer is electrically connected. When the ground on both sides of the crack subsides substantially, the sliding distance of the sliding rod in the collar becomes larger, and finally the collar touches the resistance switch, so that the buzzer works, and the monitoring personnel or the personnel around the crack A reminder is issued to warn of natural disasters (such as landslides, landslides, etc.) that may occur after the cracks have substantially subsidence.

Further, the telescopic rod includes a sleeve rod and a cross bar slidably connected in the sleeve rod, and a scale is provided on the cross rod. When the width of the crack changes, the cross bar will slide correspondingly in the sleeve rod, and the change in the width of the crack can be known by observing the scale on the cross bar at the end of the sleeve rod.

Further, an indicator light is also included, and the indicator light is electrically connected with the buzzer. When the ground on both sides of the crack has a large subsidence, the indicator light and the buzzer work together to increase the effect of prompting and early warning.

Further, the floor grip includes a support and a fixing part, the support is in the shape of a truncated cone, the support is a hollow structure with an open bottom, the upper end of the support is fixedly connected to the lower end of the bracket, and the fixing part is fixed Inside the support member, the fixing part is arranged vertically, and the lower end of the fixing part is provided with a sharp part. The fixing part is inserted under the bottom surface on both sides of the crack through the spike part, and meanwhile, the support part in the shape of a cone increases the contact area, thereby increasing the stability of the bracket. At the same time, when the fixing part is inserted into the ground, part of the soil will be extruded, and the soil will enter the inside of the support, which again increases the stability of the connection between the support and the ground.
