Description

Compressed top soil structure

The present invention belongs to the technical field of soil testing, in particular to a compressed air topping structure applied to obtain a weak muddy test body, which is directly pressurized into the thin tube sampler by air pressure, and replaces the traditional pressure with a flexible air pressure. A hard piston pushes the soil sample in the thin tube sampler.

In an indoor test to obtain the strength and deformability of soil materials, the sources of soil samples include undisturbed soil samples and heavy mold soil samples. For the acquisition of undisturbed soil samples, the sampling operation from the in-situ drilling, the operating principle is expected to obtain a soil sample sufficient to represent the state by means of non-disturbance or low disturbance. In the prior art, the local sampling mainly uses a thin tube sampler, and a thin tube test body which is undisturbed or low-disturbed can be obtained. However, when we transport the thin tubes obtained from the local sampling to the laboratory, the work to be done is the preparation of the specimens and the preparation before the test. Before the test operation, the test piece needs to be pushed out from the thin tube sampler, and this introduction process is again a disturbing behavior for the soil. For weak soils, it has the characteristics of low strength and high compressibility. When it is introduced from the thin tube sampler, how to reduce the degree of pushing disturbance to fully reflect the engineering characteristics of the local state is an important consideration in the test operation. factor.

The traditional type of top soil is pressed from one end of the sampler by a one-way piston, pushes the soil, and pushes the soil test body from the other end of the sampler. The operation mode can be divided into two types: vertical type and horizontal push type. Kind. The vertical top boring machine combines the pneumatic piston cylinder, the sampler and the mold used for the operation soil test in a vertical arrangement on a set of vertical reaction frames in an upright arrangement. Above the cylinder shaft, adjust the pressure again, use the shaft to push the soil out of the sampling tube, and the soil sample is pushed out of the sampler and then into the sample mold. The horizontal pusher can be placed on the platform, and the H-shaped steel is used as the base of the fixed sampler fixture. The rear end of the sampler is equipped with a threaded push rod and a piston, and the rotary threaded rod is used to rotate the shaft. The propulsion method pushes the piston to push the soil sample out of the sampler, and the sample is pushed out of the sampler and then continues to enter the sample mold. In the above two ways, during the process of taking out the soil test body, the test body is squeezed, and the soft body with low strength and high compression is soft. For weak soils, it has clearly affected the results of subsequent trial operations.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure with more ideal and practicality is really eagerly awaited by consumers, and it is also the goal and direction of relevant industry players to make efforts to develop breakthroughs. In view of this, the new type of person has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the new type of person has finally become a practical new model.

The technical problem to be solved: the use of the top soil squeezing device in the process of taking out the soil test body will squash the test body. For the low-strength and high-compressibility weak soil, it has obviously affected the subsequent test operation. result.

Technical feature of solving the problem: providing a compressed and compressed top-earth structure of a weak and muddy body, comprising: a bracket having a continuous perforation in the center of the bracket, and a plurality of flaps around the through hole, the bracket being provided under the through hole The accommodating space can be placed on a test piece; a positioning plate is placed on the support around the through hole, and the slats on the support abut each other, so that the positioning plate When placed on the bracket, there is no displacement and sliding; one side of the positioning plate is provided with an opening, and a baffle groove is respectively disposed at the bottom of the positioning plate on both sides of the opening; the positioning plate can fix a thin tube The position of the sampler is such that the thin tube sampler is aligned with the sample mold; wherein one side of the positioning plate can be provided with an opening for convenient access by a thin tube sampler; and a baffle can be used for the baffle Covering the through hole and slidably disposed in the baffle slot of the positioning plate; a pressing cap covering the thin tube sampler; The thin tube sampler of the soil sample is first placed on the baffle and then placed Pressing the cap, and then positioning the baffle on the edge of the opening of the positioning plate, so that the edge of the baffle is flattened to the positioning plate, and then pushing the baffle into the baffle slot and aligning the penetrating plate a hole, and finally the baffle is taken out from the baffle slot, the thin tube sampler is aligned with the test piece mold, and at this time, pneumatic pressure is applied from the top end of the pressurizing cap to the thin tube sampler, The soil sample in the thin tube sampler is moved by the air pressure and enters the test piece mold below.

Compared with the efficacy of the prior art: the present invention directly presses the air pressure into the thin tube sampler, and replaces the conventional hard piston with a flexible pneumatic pressure to push the soil sample in the thin tube sampler according to the material size. The frictional pressure, the viscous property, and the like are adjusted at any time to push the pressure of the pressure under pressure. During the pushing process, the contact interface between the soil sample and the wall of the thin sampler can be penetrated by air pressure at the interface. Forming a pressure gas film to sufficiently reduce the frictional resistance between the soil sample and the wall of the thin tube sampler, so that the soil sample can be moved without a large atmospheric pressure, and the air outlet is below the thin tube sampler Due to the diversion, an upwardly supported buoyancy can be formed to protect the soil test body, so that the bottom of the soil test body does not collapse and is flat, and the test body is slowly pushed out and successively connected to the test mold. In this process, the soil sample is pushed by the flexible atmospheric pressure, and the pressure film formed between the soil sample and the wall of the thin sampler completely reduces the disturbance of the weak soil and avoids affecting the deformation. With strength.
