Problems solved by technology

Due to the difference in the action mechanism of the pressure-dispersed anchor cable and the tension-concentrated anchor cable, the traditional anchor cable dynamometer cannot monitor the stress state of each anchor unit of the pressure-dispersed anchor cable, and it cannot effectively verify the reinforcement. effectiveness, and it is also impossible to explain the superiority of the pressure dispersion anchor cable

Embodiment Construction

[0045] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0046] One, the embodiment of complete machine, as figure 1 .

[0047] When there are three carriers (20), the first, second and third carriers (21, 22, 23) are provided.

[0048] One end of the first and second steel strands (31, 32) is respectively connected to the first carrier (21), and the other end passes through the first and second expansion holes ( 51, 52) are connected correspondingly with the 1st, 2nd anchor cable meter (61, 62), the 1st, 2nd anchor plate (71, 72), measure the stressed state of the 1st bearing body (21);

[0049] One end of the 3rd and 4th steel strands (33,34) is respectively connected to the 2nd carrier (22), and the other end passes through the 3rd, 4th expansion hole ( 53,54) are connected correspondingly with the 3rd, 4th anchor cable meter (63,64), the 3rd, 4th anchor plate (73,74) again, measure the stressed state of the 2nd b...

Abstract

The invention discloses a pressure dispersion-type anchorage cable stress state monitor, relating to an anchorage cable stress state monitor, where one end of a steel strand is connected with a bearing body and the other end in turn runs through anchor backing plate and extension hole of extension board to connect with anchorage cable meter and anchor plate correspondingly, where the anchorage cable meter measures the stress state of the bearing body; the data tester is connected with the anchorage cable meter and displays the stress state of the bearing body; the number of bearing bodies is 2-5 according to the prestress amplitude designed for the pressure dispersion-type anchorage cable. And the invention can be applied to monitor the man-made side slopes or coasts reinforced by pressure dispersion-type anchorage cable in the engineering of speedways, railways, hydropower stations, etc.

Description

technical field [0001] The invention relates to a monitoring device for the stressed state of an anchor cable, in particular to a pressure-dispersed anchor cable stressed state monitoring device; specifically, it is mainly aimed at monitoring the stressed state of a new type of pressure-dispersed anchor cable, It can evaluate the reinforcement effect of slope reinforcement using pressure-dispersing anchor cables, and at the same time provide a direct basis for analyzing the prestress loss of pressure-dispersing anchor cables, over-tensioning of anchor cables, and compensation tension. The invention can monitor and collect the force state of the pressure dispersion type anchor cable. Background technique [0002] According to statistics in recent years, the loss of economic construction and people's life and property caused by geological disasters caused by slope instability is nearly 30 billion yuan in my country every year. my country is currently in a stage of rapid econo...
