Embodiment 1

[0030] see figure 1 and figure 2 , this embodiment discloses a pipe-culvert-soil interaction test system for uneven deformation, including a test bench 1, a pipe-culvert test tank, two sets of driving systems and a test data acquisition system.

[0031] 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 . A rectangular hole 1011 is arranged on the surface of the upper platform board 101 .

[0032] see Figure 4 , the pipe culvert test tank includes a test tank bottom plate 6 and two test tank side plates 5 . The bottom plate 6 of the test tank is fixed on the lower surface of the upper platform plate 101 . The bottom plate 6 of the test tank blocks the middle part of the rectangular hole 1011 . The side plate 5 of the test tank is arranged vertically on the upper surface of the bottom plate 6 of the test tank.

Embodiment 2

[0038] This embodiment discloses a test method for the pipe and culvert test system described in Example 1, comprising the following steps:

[0039] 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.

[0040] 2) Place the pipe culvert 8 in the center and clamp it with the pipe culvert clamp 3 .

[0041] 3) Apply lubricating oil on the upper surface of the bottom plate 6 of the test tank. Soil is filled in the rectangular frame until the soil covers the upper surface of the pipe culvert 8 .

[0042] 4) Set up the test data acquisition system, and read the initial value after debugging.

[0043] 5) Adjust the transmission rod 4 to simulate the settlement of the pipe culvert 8 .

[0044] 6) 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.

[0045] 7) Remove the test data acquisition syst...

Abstract

The invention provides a pipe culvert-soil interaction test system and a test method thereof for uneven deformation. The pipe culvert test system comprises a test bed, two groups of driving systems, apipe culvert test groove and a test data acquisition system. The test bed comprises an upper-layer platform plate and a lower-layer platform plate, and supporting legs for supporting the upper-layerplatform plate and the lower-layer platform plate. Each group of driving systems comprises a driving motor, a pipe culvert clamp, a transmission rod and a guide rail. The guide rail is fixed on the lower platform plate. During the test, soil is filled in the rectangular frame body. The pipe culvert is arranged in the rectangular frame, and two ends of the pipe culvert are clamped by the pipe culvert clamp. The length direction of the pipe culvert is vertical to the direction of the guide rail. The driving motor drives the transmission rod to move on the guide rail, and then the horizontal position of the pipe culvert is adjusted. The pipe culvert test system develops a drain pipe settlement deformation monitoring simulation experiment in a 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...
