Description

Technical Field

[0001] The utility model relates to the technical field of expansive soil disease treatment, in particular to a micro-seepage neutralization device for chemical components of expansive soil. Background Art

[0002] Expansive soil is also called "swelling and shrinking soil". Expansive soil contains hydrophilic minerals such as montmorillonite, illite and kaolinite. When it meets water, it will absorb water molecules to form chemical substances with water molecular structure, thus causing volume expansion. Under certain conditions, after losing water molecules, it dehydrates and becomes the original molecular formula, and the volume is significantly reduced, thus causing volume contraction. This not only increases the hidden dangers of road traffic safety, but also increases the road maintenance costs year by year. At present, the treatment measures for expansive soil roadbed, slope and other diseases mainly adopt drainage, water isolation and water blocking technologies;

[0003] However, in the actual application of existing technical solutions, under the conditions of environmental warming and humidification and increased extreme rainfall, passive drainage methods such as water blocking and drainage are not effective, and there is a technical problem that the expansive soil disease cannot be effectively treated. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a micro-seepage neutralization device for the chemical components of expansive soil, which can solve the technical problem that under the conditions of environmental warming and humidification and increased extreme rainfall, passive drainage methods such as blocking water and diverting water are not effective and cannot effectively control the diseases of expansive soil.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a device for micro-seepage neutralization of chemical components of expansive soil, comprising an outer rotating pipe wall, a conical extrusion head is arranged at the bottom end of the outer rotating pipe wall, an inner rotating pipe wall is arranged on the inner side of the outer rotating pipe wall, an external extrusion support cover is arranged at the top end of the outer rotating pipe wall, an external extrusion rotating rod is penetrated at the middle position inside the external extrusion support cover, an outer leakage hole is arranged on the inner side wall of the outer rotating pipe wall, an inner leakage hole is arranged on the inner side wall of the inner rotating pipe wall, an internal extrusion piston is arranged on the top end of the inner part of the outer rotating pipe wall at the bottom end of the external extrusion rotating rod, and anti-blocking components are arranged on the outside of the outer rotating pipe wall at the top and bottom of the outer leakage hole.

[0006] As a preferred technical solution of the utility model, the outer side of the inner rotating tube wall and the inner side of the outer rotating tube wall are in contact with each other, and the inner rotating tube wall can rotate inside the outer rotating tube wall.

[0007] As a preferred technical solution of the utility model, the conical extrusion head is a cone, and the external extrusion rotating rod can rotate at a middle position inside the external extrusion support cover.

[0008] As a preferred technical solution of the utility model, the internal extrusion piston is disc-shaped, and the bottom end of the internal extrusion piston is fixedly connected to the top end of the inner rotating tube wall.

[0009] As a preferred technical solution of the utility model, the outer leakage holes are arranged at equal intervals on the inner side wall of the outer rotating tube wall, the inner leakage holes are arranged at equal intervals on the inner side wall of the inner rotating tube wall, and the outer leakage holes and the inner leakage holes are staggered.

[0010] As a preferred technical solution of the utility model, the anti-blocking component includes a lower protective cap, which is arranged on the outside of the outer rotating pipe wall below the outer leakage hole, and an upper protective cap is arranged on the outside of the outer rotating pipe wall above the outer leakage hole.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. The device is provided with an outer rotating pipe wall, an inner rotating pipe wall, an outer seepage hole, an inner seepage hole and a conical extrusion head. When in use, an external force is applied by an external extrusion rotating rod device to press the conical extrusion head into a hole pre-opened in the soil body to a predetermined depth. The external extrusion rotating rod is rotated at a certain angle to drive the inner rotating pipe wall to rotate and align the inner seepage hole with the outer seepage hole one by one, thereby releasing the liquid in the container and gradually penetrating into the soil layer, thereby injecting the HCL solution into the stratum with expansive soil minerals, neutralizing the hydrophilic chemical components, and achieving the purpose of eliminating the swelling and shrinkage characteristics of the expansive soil. The device can effectively treat the expansive soil disease, and the device is easy to operate;

[0013] 2. Anti-blocking components are arranged on the outside of the outer rotating pipe wall at the top and bottom of the outer leakage hole. When the outer rotating pipe wall is inserted into the preset hole under the soil, the lower protective cap can be used to prevent the outer leakage hole from being close to the hole wall. When the device is pulled out after use, the upper protective cap can be used to prevent the outer leakage hole from being close to the hole wall, thereby effectively preventing soil blocks from entering the outer leakage hole when the plug-in device is used to cause blockage and affect the normal infiltration of HCL solution into the formation with expansive soil minerals.

The top of the inner part of the outer rotating pipe wall 1 at the bottom end of the external extrusion rotating rod 4 is provided with a disc-shaped internal extrusion piston 8, and the bottom end of the internal extrusion piston 8 is fixedly connected to the top end of the inner rotating pipe wall 6. After the device is inserted into the hole, the external extrusion rotating rod 4 is rotated by a certain angle to drive the inner rotating pipe wall 6 to rotate and align the inner leakage holes 7 with the outer leakage holes 2 one by one, so that the liquid in the container is released and gradually penetrates into the soil layer, so that the HCL solution can be injected into the stratum with expansive soil minerals, and the hydrophilic chemical components are neutralized to achieve the purpose of eliminating the swelling and shrinkage characteristics of the expansive soil, which can effectively treat the expansive soil disease, and the device is easy to operate;

[0021] When in use, an external force is applied by the external extrusion rotating rod 4 device to press the conical extrusion head 5 into a predetermined depth in a hole pre-opened in the soil body, and the external extrusion rotating rod 4 is rotated by a certain angle to drive the inner rotary pipe wall 6 to rotate so that the inner leakage hole 7 is aligned with the outer leakage hole 2 one by one, thereby releasing the liquid in the container and gradually penetrating into the soil layer to treat the expansive soil;
