Description

Technical Field

[0001] The utility model relates to the technical field of direct shear instruments, in particular to a shear box based on the direct shear instrument and convenient for taking soil samples after testing. Background Art

[0002] Direct shear apparatus, also known as direct shear apparatus for short, is used to perform direct shear tests on objects. In construction, it is often necessary to measure the strength of prepared soil samples. Currently, the soil samples for strength testing are formed by placing soil particles on a soil sample molding device and compacting them. The prepared soil samples are then placed in the grooves of the upper and lower boxes on the direct shear apparatus for shear tests to determine their strength data.

[0003] However, since the cut surface of the soil sample after the test is flat and basically flush with the surface of the lower box, this shear box structure makes it difficult to remove the soil sample from the lower box after the test, and it is difficult to ensure the integrity of the removed soil sample due to the human force during the removal process, which affects the subsequent research of certain special experiments. At the same time, the soil sample residue in the lower box may affect the next experiment. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a shear box based on a direct shear apparatus for facilitating soil sampling after testing.

[0005] The utility model is implemented by the following technical scheme: a shear box based on a direct shear instrument for facilitating soil sampling after testing, comprising a support table, a lower box body is fixedly connected to the middle of the upper surface of the support table, a top support assembly is arranged in the middle of the inner bottom wall of the lower box body, and a resistance block is fixedly connected to one side of the outer surface of the lower box body;

[0006] The supporting assembly includes a metal sheet, which is arranged on the inner bottom wall of the lower box body. A stainless steel handle is fixedly connected to the inside of the metal sheet. A through hole is opened in the middle of the inner bottom wall of the lower box body, and the outer surface of the stainless steel handle is inserted into the inside of the through hole.

[0007] Through the above technical scheme, a through hole is opened at the center of the bottom wall of the lower box body, and the lower box body is paved with a metal sheet with the same circular inner diameter as the through hole. A stainless steel handle is fixed at the place connected to the center of the metal sheet. The stainless steel handle passes through the through hole, which is convenient for personnel. After the experiment, the experimenter can use the stainless steel handle to completely lift out the soil sample embedded and sheared in the lower box body, avoiding the difficulty in ensuring the integrity of the soil sample due to the human force during the removal process, which affects the subsequent research of certain special experiments, thereby ensuring the accuracy and convenience of the experiment of scientific researchers.

[0008] As a further improvement of the above solution, an upper box body is arranged on the upper surface of the lower box body, and bolt holes are provided at the four corners of the surfaces of the lower box body and the upper box body.

[0009] Through the above technical solution, the lower box body and the upper box body cooperate with each other to squeeze and compact the soil sample to be tested, so that the soil sample can be evenly dispersed on the surface of the metal sheet, making it convenient for personnel to observe the soil sample later.

[0010] As a further improvement of the above solution, a square pressing piece is fixedly connected to the interior of the upper box body, and a top pressing piece is fixedly connected to the upper surface of the square pressing piece.

[0011] Through the above technical solution, the square pressure piece and the top pressure piece are used together to move the soil sample on the top to the bottom through pressure, and then the soil sample is compacted to facilitate subsequent experimental measurements of the soil sample by personnel.

[0012] As a further improvement of the above solution, pressure holes are provided inside the top pressure piece and the square pressure piece, and a pressure block is fixedly connected to one side of the surface of the top pressure piece.

[0013] Through the above technical solution, the pressure block can enable the top pressure piece to generate pressure on the internal soil sample when working, so that the soil sample can move downward along the pressure hole.

[0014] As a further improvement of the above solution, a preset pressure plate is fixedly connected to the upper surface of the top pressure piece, a diagonal support frame is fixedly connected to one side of the resistance block, and a connection box is fixedly connected to one side of the diagonal support frame.

[0015] Through the above technical solution, the diagonal support frame and the connecting frame can improve the stability of the overall device when it is placed, and avoid the problem of inaccurate measurement data caused by the displacement and shaking of the lower box body.

[0016] As a further improvement of the above solution, a support seat is fixedly connected to the other side of the outer surface of the lower box body, a pressure rod is inserted into the interior of the support seat, and a pressure gauge is fixedly connected to one end of the pressure rod.

[0017] Through the above technical solution, the pressure gauge can be convenient for personnel to make timely adjustments, so that personnel can observe the value of the internal pressure from the outside.

[0018] As a further improvement of the above solution, anti-sliding blocks are fixedly connected to both sides of the lower surface of the support platform, bearing seats are fixedly connected to the top and bottom of the front of the anti-sliding block, and a shock-absorbing cylinder is fixedly connected to the interior of the bearing seat.

[0019] Through the above technical solution, the volume of the shock-absorbing cylinder is larger, so that when the device is impacted by the outside world, it can rotate along the bearing seat and unload the force through rotation, thereby effectively protecting the device from the influence of external impact force during the experiment and improving the service life of the device.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model provides a supporting component, a through hole is opened at the center of the bottom wall of the lower box body, the lower box body is paved with a metal sheet with the same circular inner diameter as the through hole, a stainless steel handle is fixed at the place connected to the center of the metal sheet, and the stainless steel handle is passed through the through hole, so that after the experiment, the experimenter can completely support the soil sample embedded and sheared in the lower box body through the stainless steel handle, so as to avoid the difficulty in ensuring the integrity of the soil sample due to the human force in the process of taking out, which will affect the subsequent research of some special experiments, and ensure the accuracy and convenience of the experiment of scientific researchers.
