Description

Technical Field

[0001] The utility model relates to the field of soil water infiltration, in particular to a novel rammed earth and soil loading system for infiltration test. Background Art

[0002] The soil infiltration process determines the amount of precipitation or irrigation water that enters the soil. It is not only related to the water supply for the current season's crops, but also to the storage of deep water for use by crops after the water supply or in the next year. In mountainous areas, hills and sloping land, the infiltration process also determines the quantitative distribution between surface runoff and water infiltrating into the soil. Soil infiltration research is of great significance for rainfall runoff regulation, soil and water conservation, water resources evaluation and management, and determination of farmland irrigation technical parameters.

[0003] Before the indoor infiltration test, the test soil needs to be calculated according to the relevant design and then filled in layers according to the designed bulk density. The experimenters use manual tampers to compact the soil, which is prone to uneven force application, resulting in different bulk densities of the compacted soil. The compaction process is time-consuming and labor-intensive.

[0004] The soil box used in indoor infiltration tests is mostly a device that is closed on all sides. When the soil box is high, it is more difficult to apply vaseline and clean the soil box, which can easily lead to residues of vaseline and test soil, resulting in deviations in the test results. Summary of the invention

[0005] The utility model aims to provide a novel rammed earth and soil loading system for infiltration test to solve the problems mentioned in the above background technology.

[0006] The purpose of the utility model is achieved as follows: a novel ramming and loading system for infiltration test, comprising a ramming device and a soil box, the ramming device comprising a support column, a bearing structure, a motor, a bulldozer, a driving connecting rod, a pushing connecting rod, a common connecting rod, a pressing connecting rod, and a ramming device, the soil box comprising a scale, a groove, and a ramming mouth, the support column is used to support the bearing structure, the motor is placed on the left side of the bearing structure and is connected to the driving connecting rod, the pushing connecting rod causes the bulldozer to move forward and backward, and pushes the test soil that slides into the right side of the bearing structure into the soil box, the common connecting rod connects the bulldozer and the pressing connecting rod, and together drives the ramming device to move up and down, and presses the test soil in the soil box evenly to the scale, and the groove can be used to place and remove the plexiglass plate, so that the soil box forms a detachable test space.

[0007] Preferably, the bearing structure is provided with a soil inlet, a soil inlet channel and vertical rods. When loading soil, the experimenter can place the soil on the soil inlet channel. The soil slides downward under the action of gravity and slides into the right side of the bearing structure through the soil inlet, which can reduce some dust generated during the soil loading process.

[0008] Preferably, the vertical rod is used to fix the downward pressing connecting rod, and there are two downward pressing connecting rods to ensure that the tamping machine can move vertically up and down.

[0009] Preferably, the motor is placed on the left side of the bearing structure and connected to the driving connecting rod. The driving connecting rod and the pushing connecting rod form a crank mechanism to realize automatic reciprocating motion of the system.

[0010] Preferably, the pushing connecting rod causes the bulldozer to move forward and backward, pushing the test soil that slides into the right side of the bearing structure into the soil box. The bulldozer drives the rammer to reciprocate up and down through the common connecting rod and the downward pressure connecting rod, and presses the soil in the soil box evenly to the scale.

[0011] Preferably, the ramming tool is divided into a ramming rod and an iron block, the upper end of the ramming rod is fixed on the downward pressure connecting rod, and the lower end is connected to the iron block. The size of the iron block is slightly smaller than the ramming mouth, so that the test soil in the soil box can be accurately compacted under the action of the downward pressure connecting rod to avoid damage to the device.

[0012] Preferably, the groove can be used to place and remove the organic glass plate, so that the soil box forms a detachable test space, which is convenient for applying vaseline before the test and cleaning the soil box after the test.

[0013] The beneficial effects of the utility model are as follows: traditional manual tamping tools are prone to uneven force application during the tamping process, and manual tamping is generally done in layers of 5 cm, which is time-consuming and labor-intensive. The tamping tool of the utility model can tamp a layer of 10 cm or more, and force is applied evenly during the tamping process to ensure that the soil in each layer is compacted to the designed bulk density. When the height of the traditional infiltration soil box is high, it is difficult to apply vaseline and clean the soil box. The groove is provided for the placement and removal of the plexiglass plate, thereby breaking the closed space of the traditional soil box, making the application of vaseline and the cleaning of the soil box more convenient. The operation is simple, time-saving and labor-saving, and work efficiency can be improved, and the test accuracy can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Furthermore, the novel rammed earth and soil loading system for infiltration test has a support column 1 for supporting a bearing structure 2, on which a soil inlet 21, a soil inlet channel 22, and a vertical rod 23 are distributed. When loading soil, the soil is placed on the soil inlet channel 22, and the soil slides downward under the action of gravity and slides into the right side of the bearing structure 2 through the soil inlet 21, which can effectively avoid the generation of a large amount of dust during the soil loading process. The vertical rod 23 is used to fix the downward pressing connecting rod 8.

[0027] Furthermore, the novel tamping and loading system for infiltration test has two downward pressing connecting rods 8 for ensuring that the tamping device 9 can move vertically up and down.

[0028] Furthermore, in the novel ramming and loading system for infiltration test, the motor 3 is placed on the left side of the bearing structure 2 and connected to the driving connecting rod 5.

[0031] Specifically, the working principle of the new rammed soil and soil loading system for infiltration test is as follows: when in use, first apply vaseline on the front side and left and right sides of the soil box 10, then apply vaseline on the plexiglass plate and place it in the groove 102 to assemble the space required for the infiltration test. After calculating the weight of a layer of test soil required according to the designed bulk density, place it on the soil entry channel 22, and after the soil slides into the right side of the bearing structure 2 under the action of gravity, turn on the motor 3 to drive the driving connecting rod 5 to rotate, and the driving connecting rod 5 drives the pushing connecting rod 6 to move, so that the bulldozer 4 pushes the test soil that slides into the right side of the bearing structure 2 into the soil box 10, and the bulldozer 4 drives the ramming device 9 to reciprocate up and down through the ordinary connecting rod 7 and the pressing connecting rod 8, and presses the soil in the soil box 10 evenly and accurately to the scale 101. After a layer of soil is compacted, turn off the motor, perform interlayer roughening, and then repeat the steps of loading soil, ramming soil, and roughening until the ramming is completed and the infiltration test begins. After the test, the plexiglass plate is taken out and one side of the soil box is opened to facilitate the cleaning of the test soil and the cleaning of the soil box. The whole system is easy to operate and can quickly and effectively fill the soil so that the soil in each layer is evenly stressed, saving time and effort. It is convenient for applying vaseline before the test and cleaning the soil box after the test, which can improve work efficiency and test accuracy.
