Background technology
The long defeated buried pipeline of oil gas is except bearing interior pressure, also be subject to due to soil move, sedimentation or Geological Reasons and the bending stress produced such as to subside, the pipeline be laid in software ground can produce various distortion because of sedimentation, serious meeting makes pipeline produce crack and fracture, and affects normal use and the safe operation of pipeline.At present, each research institution test unit that shop experiment makes has a lot, but can effectively simulated soil sedimentation or to subside on the impact of buried pipeline and to be specifically designed to the test unit of laboratory study also very rarely seen, how accurately and effectively the parameter such as analog basis sedimentation length, width is on the impact of buried pipeline mechanical property, the problem that the person that is pipeline management and scientific research personnel's letter need solve.
Summary of the invention
In order to solve the technical matters mentioned in background technology, the utility model provides a kind of test unit for simulating buried pipeline settlement of foundation, this kind of test unit can control settlement of foundation section length by regulating two pieces of pull plates of test bottom half, the control settlement degree of depth is carried out by regulating the pallet height of test bottom half, thus realize the experiment lab simulation of buried pipeline settlement of foundation, there is the advantages such as conveniently moving, convenient operation, yardstick be controlled.
The technical solution of the utility model is: this kind is for simulating the test unit of buried pipeline settlement of foundation, comprise casing, pallet and four support threaded rods, the main frame of described casing is formed after four upright of frame, two framework wide plates and two framework long slabs weld; Wherein, four upright of frame, two framework wide plates and two framework long slabs have glass slot respectively on correspondence direction, vertically insert in described glass slot respectively for four pieces, front, rear, left and right transparent plexiglass plate; Difference perforate on left and right two pieces of transparent plexiglass plates, hole is embedded in the fixing circular folder of a telescopic pipeline, and two telescopic pipelines are fixed the circular center of circle pressed from both sides and are positioned on straight line; The lower end of described upright of frame has blind hole, and the internal diameter of described blind hole inserts to make support threaded rod slightly larger than the external diameter supporting threaded rod, and the degree of depth of described blind hole is identical with the height of described support threaded rod; Described two framework wide plates have pull plate outlet can extract out for a pair pull plate in the horizontal direction and push, on described two framework long slabs, correspondence has the location sliding tray moved horizontally for described pull plate; Pull plate penetrates the outlet of described pull plate and is positioned at described location sliding tray;
The bottom of four support threaded rods is fixedly connected on four angles of pallet respectively, and the head end of four support threaded rods inserts in corresponding upright of frame lower end blind hole respectively; Supporting the adjustment jackscrew that threaded rod is threaded for adjusting described support threaded rod insertion blind hole depth;
Described framework long slab is carved with horizontal scale chi, described upright of frame is carved with vertical rule.
The utility model has following beneficial effect: this apparatus main body is the casing of metallic support framework, tempered glass.Bottom half both sides respectively have one piece of pull plate waiting width in the width direction, settlement of foundation section length is controlled by regulating two pieces of pull plates, its length is measured by bottom half scale along its length, suppose the soil body from the middle of at the bottom of pipe progressively to both sides sedimentation, with the extraction of pull plate, sand flows out fast in the middle of two pieces of pull plates, and namely the length between two pieces of pull plates represent negative area length.Below pull plate be one piece and along the pallet of short transverse activity, can be controlled the height of pallet movement by the jackscrew between adjusting tray and casing, for controlling the discharge of sand, the distance that base plate moves up and down is measured by the scale along short transverse.Pipeline is placed in the Telescopic Fixed device of the casing left and right sides, its size can regulate, and meets the demand of different tube diameters.During simulation test, lay the soil body at pipeline upper and lower, and then as required at casing top load application.As needs, displacement meter can be installed at Guan Ding, after soil body settlement stability, the sedimentation deformation of pipe can be measured by displacement meter.This kind of device can realize the experiment lab simulation of buried pipeline settlement of foundation, has the advantages such as conveniently moving, convenient operation, yardstick be controlled.
