Description

Technical Field

[0001] The present application relates to the technical field of soft foundation reinforcement equipment, and more specifically, to a soft foundation reinforcement device for engineering foundation construction. Background Art

[0002] my country's highway industry specifications define soft soil foundation as a weak soil layer with low strength and high compression, most of which contain a certain amount of organic matter. Therefore, the soft foundation needs to be reinforced. At present, the reinforcement treatment of soft foundation mostly adopts the method of strong compaction. Before the strong compaction of the soft foundation, it is necessary to lay a layer of loose materials such as sand, gravel or crushed stone with a thickness of about 0.5-2m on the surface of the soft foundation. The purpose of this is to form a hard layer on the surface, which is conducive to the entry of strong compaction equipment for construction.

[0003] The document with prior art publication number CN218712853U provides a soft foundation reinforcement device for engineering construction, which has the function of enabling a first gear fixedly connected to an output end of the first motor to rotate by starting a first motor, thereby causing the first gear to move forward and backward in a first tooth groove, and then causing a first sliding rod fixedly connected to the first gear to move forward and backward, thereby causing a sliding block slidably connected to the first sliding rod to slide back and forth, and enabling a first gear fixedly connected to an output end of the second motor to rotate by starting a second motor, thereby causing the first gear to move left and right in a second tooth groove, and then causing a second sliding rod fixedly connected to the first gear to move forward and backward, thereby causing a sliding block slidably connected to the second sliding rod to slide back and forth, and then allowing the counterweight block to be adjusted back and forth and left and right, thereby improving the efficiency of reinforcing the soft foundation.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: although the above-mentioned prior art soft foundation reinforcement device can compact and reinforce the soft foundation by the free downward falling counterweight block colliding with the soft foundation, it will cause dust to fly at the ramming site, which will not only pollute the air environment, but also be detrimental to the health and safety of on-site operators.

[0027] 3. Beneficial effects

[0028] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0029] 1. This soft foundation reinforcement device can perform cyclic compaction and reinforcement treatment on the soft foundation encountered in the process of engineering foundation construction through the compaction structure connected to the mobile frame, and when compacting the soft foundation, it can also perform negative pressure dust removal treatment on the dust raised when compacting the foundation through the negative pressure adsorption component connected to the mobile frame, thereby effectively reducing the degree of pollution to the construction environment during the soft foundation compaction and reinforcement process, which is beneficial to environmental protection and is also beneficial to the health and safety of on-site operators.

[0030] 2. The braked universal wheels at the bottom of the mobile frame can be used to facilitate the movement of the device to the position to be compacted and reinforced.

[0031] 3. The electric cylinder drives the compaction weight to reciprocate up and down, and then the falling compaction weight collides with the soft foundation to achieve compaction and reinforcement of the foundation.

[0032] 4. The dust raised when the compaction weight collides with the tamped foundation is continuously sucked into the air inlet hood under the action of the negative pressure suction of the vacuum pump, and then the dust sucked into the inner cavity of the negative pressure cylinder is intercepted and filtered by the dust filter and collected in the inner cavity of the negative pressure cylinder. The air pressure sensor monitors the air pressure in the space above the outer frame of the inner cavity of the negative pressure cylinder in real time, and transmits the detection value to the external main controller in real time. When the dust filter is blocked and the detection value of the air pressure sensor is lower than the predetermined critical value, the external main controller controls the sound and light alarm to turn on, and then the sound and light alarm sends an alarm signal to remind the staff to remove the dust filter from the inside of the negative pressure cylinder in time and clean it.

[0033] 5. After the foundation compaction and reinforcement work is completed, the staff will move the device to the garbage disposal point. When the dust collected inside the negative pressure cylinder needs to be cleaned, the device will be moved to the garbage disposal point first, and then the cover connected to the bottom of the negative pressure cylinder will be removed, and then the cover will be slowly moved vertically downward. During this process, the elastic sponge ring that is tightly attached to the side wall of the inner cavity of the negative pressure cylinder will gradually scrape off the dust adhering to the side wall of the inner cavity of the negative pressure cylinder. When the inner ring seat is completely removed from the inner cavity of the negative pressure cylinder, the dust accumulated on the surface of the cover will be dumped down, so that people can clean up the dust raised during the compaction of the soft foundation collected in the negative pressure cylinder.
