Description

Device is buried underground to upright pipe

Technical Field

The utility model relates to a safety monitoring technical field of dam amount of deflection specifically is a device is buried underground to positive plumb pipe.

Background

Concrete dams are usually built on foundations with complex geological structures and uneven geotechnical characteristics, and the working performance and safety condition of the concrete dams change at any time under the influence of various forces and natural factors. If the abnormality occurs, the situation and the nature of the change can not be grasped in time by people, the dangerous situation can be developed, and the fruit can not be imagined later. In the French Marbagel (the M vertical pipe burying device lp vertical pipe burying device sset) hyperbolic arch dam with the dam height of 66.5M built in 1954, rock mass of the left dam abutment part is unevenly deformed and slides under the action of uplift pressure after water storage. The result was a sudden crash in 1959 on 12/2 without any awareness of the managers due to the unnecessary safety monitoring facilities. The short time is 45 minutes, 500 soldiers in a barrage 8km downstream of the dam can be completely killed, a town 10km away from the dam becomes ruin, and the direct economic loss is 6800 ten thousand dollars. If necessary observation means are arranged in advance to monitor the projects, problems can be found in time, and effective measures are taken, so that the disasters can be avoided. In 1962,

day

11 and 6, a great amount of water leakage is found in the foundation rock of the right bank of the arch dam of Meishan Liang in Anhui province, the vertical line coordinatograph of No. 13 dam stack of the right bank inclines by 57.2mm to the left bank within three days, the vertical line coordinatograph is shifted by 9.4mm to the downstream, and large cracks appear in each stack of the right bank successively, and the foundation rock of the right bank is dislocated by analysis. Therefore, the reservoir is timely emptied under the monitoring of the plumb line instrument for reinforcement treatment, so that a dam break accident is avoided. The above two examples fully illustrate how safety monitoring using instrumentation is important to the safety of buildings and people.

In concrete dams, particularly arch dams and hyperbolic arch dams, dam deflection observation is particularly important, and normally, the plumb line is a normal observation facility for observing dam deflection in combination with the inverted plumb line.

Therefore, in order to solve the above problems, a pre-buried vertical pipe device and an operation method thereof in a concrete dam have great practical significance.
