Description

Technical Field

[0001] The utility model relates to the technical field of underground soil layer replacement, in particular to underground soil layer replacement equipment for municipal engineering. Background Art

[0002] Municipal infrastructure projects refer to the civil engineering, pipeline and equipment installation projects of urban roads, public transportation, water supply, drainage, gas, heat, gardens, sanitation, sewage treatment, garbage disposal, flood control, underground public facilities and ancillary facilities. Municipal engineering projects include the planning and construction of urban roads. With the acceleration of urbanization, the greening level of cities is gradually improving. Parks and gardens with water absorption and filtration functions have become an important aspect of future design. Rainwater is filtered by setting different soil layers, but after long-term use, the filter soil layer under the soil will be blocked, causing hypoxia in the layer, which will in turn cause the reproduction of anaerobic organisms to accelerate, aggravate the blockage of the filter soil layer, and ultimately make it difficult for the filter soil layer to infiltrate. To deal with this situation, the underground soil layer is generally excavated and replaced, and then the ground soil layer is refilled.

[0003] According to the patent publication number CN 111742626 B, a soil-changing device for underground soil layers in municipal engineering is proposed, which includes a walking mechanism and an actuator. The soil-changing mechanism designed in the present invention can extend into the filtering soil layer on the lower side of the soil to replace the filtering soil layer, thereby preventing the filtering soil layer under the soil from being blocked after long-term use. In order to reduce the wear of the mechanical arm when the soil-changing mechanism is driven forward by the mechanical arm, the service life of the mechanical arm is reduced; in the present invention, the first spiral blade and the second spiral blade are designed to rotate in opposite directions and also have the function of crushing soil blocks; when the first spiral blade rotates forward, it squeezes the soil layer in the corresponding area, causing it to be compressed into blocks, and when the second spiral blade rotates through these blocks, it will cut the blocks in a spiral to crush them; the porosity of the soil layer is increased, the filtering capacity of the filtering soil layer after soil replacement is increased, and the infiltration rate is increased.

[0004] The problem with the above-mentioned soil replacement device for municipal engineering is that after the device completes the excavation and soil replacement operation, it is necessary to drive the special soil transport equipment again to lay the surface soil layer. This soil replacement process is relatively cumbersome and time-consuming, which reduces work efficiency. Utility Model Content

[0041] Embodiment The implementation principle of a municipal engineering underground soil layer replacement equipment is as follows:

[0042] The equipment is moved to the area to be replaced by the traveling mechanism at the bottom of the traveling body 1, and the ground soil layer to be filled is filled in the soil hopper 8 on the traveling body 1. The soil replacement mechanism 3 inside the bottom trough 2 is started to start the ground excavation and soil replacement operation, and the push cylinder 11 is started to drive the telescopic shaft 12 to reciprocate. The movement of the telescopic shaft 12 drives the first folding frame 14 and the second folding frame 15 to fold and stretch each other.

The soil replacement function and the ground soil backfill function are integrated into one, and the landfill measures can be connected at the same time after the excavation and soil replacement operation is completed, which saves a lot of working time and improves work efficiency. It can also avoid the situation where the top soil layer is not landfilled for a long time after the soil replacement operation is completed, causing the underground soil layer to be dried out by radiation, thereby affecting the filtering effect.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
