Description

Technical Field

[0001] This utility model relates to the field of fine-grained soil detection technology, specifically to a high-efficiency fine-grained soil unrestricted device. Background Technology

[0002] Soil with less than 50% coarse particles (greater than 0.075mm) is generally referred to as fine-grained soil. It also refers to soil with a maximum particle size of no more than 4.75mm and a nominal maximum particle size of no more than 2.36mm, including various clay soils, silt soils, sand, and gravel. In current municipal engineering construction, it is necessary to conduct compression testing on fine-grained soil. After compression, fine-grained soil will form a cylindrical soil column.

[0003] The testing process is as follows:

[0004] Fine-grained soil is placed in a single cylinder, and the two sides are sealed with metal parts. The sealing parts are then squeezed using hydraulic equipment. Finally, the squeezed fine-grained soil is tested.

[0005] However, for the sake of accuracy, a single fine-grained soil test is usually repeated 4-6 times. The staff needs to repeatedly pour, squeeze, and dump the soil, and finally record the results, which is quite tedious.

[0006] Secondly, the cylinder and sealing components are more likely to be lost if stored separately. Utility Model Content

[0007] The purpose of this invention is to provide a high-efficiency device for fine-grained soil without side restraints, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A high-efficiency fine-grained soil unrestricted device includes several sealing components, a placement cylinder, and a connecting plate. The placement cylinder is provided with sealing components inside, and a connecting plate is provided in the middle of the placement cylinder. A fixing plate is fixed to the connecting plate near the placement cylinder. Two placement grooves are opened through the outer wall of the connecting plate. A storage cylinder is provided below the placement grooves. Handles are provided on the left and right sides of the connecting plate.

[0010] When the two sealing elements are inside the placement cylinder, the fine soil particles are located in the middle of the two sealing elements.

[0011] Furthermore, the placement tube is a hollow cylindrical shape, the placement tube is made of metal, and two sealing components are placed in the middle of each placement tube.

[0012] Furthermore, a groove is formed in the middle of the fixing plate, and a threaded groove is formed at the corresponding position of the placement cylinder and the groove of the fixing plate.

[0013] Furthermore, the diameter of the storage cylinder is larger than the diameter of the sealing element.

[0014] Furthermore, the sealing component is made of the same material as the placement cylinder.

[0015] Furthermore, the outer wall of the handle is provided with an anti-slip pad.

[0016] Furthermore, a finger groove is provided on the upper outer wall of the sealing component.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The fine-grained soil forming device provided by this utility model is mainly used for the extrusion and limiting of fine-grained soil. The device can test up to six soil samples at a time. The placement cylinder and the connecting plate are detachable, and the number can be selected by the operator. The assembled device is then placed under the hydraulic equipment to perform extrusion work simultaneously.

[0019] 2. The connecting plate of this utility model is equipped with handles on both sides, which can be used by workers to lift the equipment itself, thus facilitating its handling.

[0020] 3. The two storage cylinders of this utility model are used to place the sealing components, which can reduce the risk of loss after the sealing components are placed. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] This utility model is mainly used for compression limiting of fine-grained soil.

[0029] like Figure 1-4 As shown, a high-efficiency fine-grained soil compression device includes several sealing components 1, a placement cylinder 2, and a connecting plate 3. The placement cylinder 2 is equipped with sealing components 1, and the middle of the placement cylinder 2 is equipped with a connecting plate 3. A fixing plate 6 is fixedly connected to the connecting plate 3 near the placement cylinder 2. Two placement grooves 5 are opened through the outer wall of the connecting plate 3. A storage cylinder 7 is set below the placement grooves 5. Handles 4 are set on the left and right sides of the connecting plate 3. This device is mainly used for compression and limiting of fine-grained soil. The device can test up to six soil samples at a time. The placement cylinder 2 and the connecting plate 3 are detachable. The number of samples can be selected by the operator. The assembled device is placed under the hydraulic equipment to perform compression work simultaneously.

[0030] When the two sealing components 1 are inside the placement cylinder 2, the fine soil is in the middle of the two sealing components 1. After the fine soil is placed and the two sides are sealed, the extrusion process can be completed by the extrusion equipment.

[0031] In one embodiment, the placement cylinder 2 is a hollow cylindrical shape, made of metal, and two sealing components 1 are placed in the middle of each placement cylinder 2.

[0032] In one embodiment, a groove is provided in the middle of the fixing plate 6, and a threaded groove is provided at the corresponding position of the placement cylinder 2 and the groove of the fixing plate 6. Bolts can be used to install the placement cylinder 2 on the outer wall of the connecting plate 3.

[0033] In one implementation, the diameter of the storage cylinder 7 is larger than the diameter of the sealing element 1. Two storage cylinders 7 are used to place the sealing element 1, which reduces the risk of loss after the sealing element 1 is placed.

[0034] In one implementation, the sealing component 1 and the placement cylinder 2 are made of the same material, both of which are made of carbon steel, which can increase the overall service life.

[0035] As one implementation, the outer wall of the handle 4 is provided with an anti-slip pad, which can increase the friction of the outer wall of the handle 4. The connecting plate 3 is equipped with handles 4 on both sides, which can be used by the staff to lift the equipment itself, thereby facilitating its handling.

[0036] In one embodiment, a finger groove is provided on the upper outer wall of the sealing member 1. The finger groove is provided on the upper part of the sealing member 1. The finger groove is mainly used to facilitate the lifting of the sealing member 1 during operation, and the finger groove itself does not affect the squeezing operation.

[0037] This utility model uses hydraulic equipment to compress itself.

[0038] Generally, fine-grained soil will become a cylindrical soil column after being compressed. The compressive strength of the fine-grained soil can be determined by using hydraulic equipment to compress the soil column. This utility model can form multiple soil columns at once, which can reduce the workflow.

[0039] Its compaction degree (%) = (measured dry density / maximum dry density) × 100%.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
