Embodiment 1

[0026] This embodiment discloses a pipe and culvert test system under uneven deformation, including a test bench 1, two sets of drive systems and a test data acquisition system.

[0027] The test bench 1 includes an upper platform board 101 and a lower platform board 102 , and supporting legs 103 supporting the upper platform board 101 and the lower platform board 102 .

[0028] Each group of driving systems includes a driving motor 2 , a pipe culvert clamp 3 , a transmission rod 4 and a guide rail 15 . The guide rail 15 is fixed on the lower platform board 102 . The transmission rod 4 includes a transmission rod main body 401 and a connecting portion 402 arranged beside the transmission rod main body 401 . The transmission rod main body 401 is placed above the guide rail 15 . The upper platform board 101 is provided with a hollow part at a position corresponding to the main body of the transmission rod 401 . The upper end of the transmission rod main body 401 protrudes fro...

Embodiment 2

[0033] This embodiment discloses a test method for the pipe and culvert test system described in Example 1, comprising the following steps:

[0034] 1) Put the test bench 1 in an appropriate position and turn on the power. Adjust the two sets of pipe culvert clamps 3 to their original positions.

[0035] 2) Place the pipe culvert 8 in the center and clamp it with the pipe culvert clamp 3 .

[0036] 3) Lay out the test data acquisition system, and read the initial value after debugging.

[0037] 4) Adjust the transmission rod 4 to simulate the settlement of the pipe culvert 8 .

[0038] 5) Record the reading of the pointer on the scale according to the number of the test bench, and the monitoring equipment collects the test data.

[0039] 6) Remove the test data acquisition system and remove the pipe culvert 8.

[0040] 7) Data processing, researching the relationship between the displacement and internal force of the pipe culvert 8 according to the data.

Abstract

The invention provides a pipe culvert test system used under inhomogeneous deformation and a test method thereof. The pipe culvert test system comprises a test stand, two sets of driving systems and atest data acquisition system. The test stand comprises an upper layer platform plate, a lower layer platform plate, and supporting legs supporting the upper layer platform plate and the lower layer platform plate. Each set of driving systems comprises a driving motor, a pipe culvert fixture, a transmission rod, and a guide rail. The guide rails are fixed on the lower layer platform plate. Duringthe test, a pipe culvert is arranged in a rectangular frame, both ends are clamped by means of the pipe culvert fixture, the length direction of the pipe culvert is perpendicular to the direction of the guide rails, and the driving motors drive the transmission rods to move on the guide rails so as to adjust the horizontal position of the pipe culvert. The pipe culvert test system is used for carrying out a drainage pipe settlement deformation monitoring simulation experiment in the laboratory.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a pipe and culvert experiment system. Background technique [0002] The urban drainage pipe network is a service infrastructure with the functions of urban flood control, rainwater discharge and treatment, reclaimed water production and utilization, and sludge treatment. Typically, aging, corrosion, and disturbance are the main causes of drain damage. In recent years, urban rail transit and deep foundation pit projects have increasingly disturbed the urban drainage pipe network. Ground subsidence accidents caused by pipe settlement deformation, rupture, and leakage have occurred from time to time, seriously threatening the lives and property safety of citizens. In order to realize the automatic monitoring and early warning of drainage pipes and effectively prevent and control the safety risks of urban drainage pipes, it is necessary to experimentally study the monitori...
