Abstract
Description
Technical Field
[0001] This utility model belongs to the field of road construction technology, specifically a soft soil foundation treatment device. Background Technology
[0002] In municipal road construction, especially in southern regions, soft soil subgrades are common. Soft soil subgrades are a special type of subgrade found in certain areas, characterized by high water content, poor permeability, low natural strength, and high compressibility. If the critical height is exceeded, the foundation will lose stability. Soft soil foundations require solidification treatment to ensure their strength, and road soft soil foundation solidification treatment devices are generally used.
[0003] Cement mixing piles are an effective form of soft soil foundation treatment. They utilize cement as the main curing agent, employing a mixing pile machine to inject cement into the soil and thoroughly mix it. This causes a series of physicochemical reactions between the cement and the soil, hardening the soft soil and increasing the foundation strength. Existing cement mixing pile technologies mostly employ single-axis, double-axis, and triple-axis methods. However, due to the relatively low efficiency of single-axis mixing piles, double-axis or triple-axis methods are generally used. But existing double-axis mixing piles have the following drawbacks: Double-axis mixing piles typically have two drill rods and two helical pile heads, allowing for the simultaneous construction of two piles. However, the spacing between the drill rods is fixed, making it difficult to adjust the spacing according to specific construction needs. This limits the flexibility of construction and thus has certain shortcomings. Utility Model Content

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figures 1 to 4 As shown, this utility model provides a soft soil foundation treatment device, including a supporting base plate 100 and a supporting frame 101 disposed on the top of the supporting base plate 100. A top frame 102 is disposed on the top of the supporting frame 101. A first mounting frame 200 is slidably connected to the outer wall of the supporting frame 101. A second mounting frame 201 is movably disposed on the first mounting frame 200. A mixing pile 300 is disposed on the second mounting frame 201. A first driving component 400 is disposed between the top frame 102 and the supporting base plate 100 for driving the first mounting frame 200 to move up and down along the supporting frame 101 to drive the mixing pile 300 to move up and down for piling. A second driving component 500 and a third driving component 500 are disposed on the second mounting frame 201 for driving the second mounting frame 201 to move longitudinally or laterally along its outer wall to adjust the position of the mixing pile 300. The moving component 600 and the top frame 102 are equipped with a storage tank 700 that communicates with the interior of the mixing pile 300. In use, the device is moved to the soft soil foundation to be treated. The spacing between the mixing piles 300 and the drilling position are adjusted by the second drive component 500 and the third drive component 600, respectively, and the mixing pile 300 is started to rotate spirally. This is an existing mature technology, so it will not be described in detail. The first drive component 400 drives the first mounting frame 200 to move downward along the support frame 101, which can drive the mixing pile 300 to move downward and drill into the soft soil foundation. Then, the solidifying agent inside the storage tank 700 is delivered to the interior of the mixing pile 300 through the delivery hose by the external drive component and then sprayed into the soft foundation. The mixing pile 300 mixes and mixes the mixture to achieve the effect of solidification treatment.
[0020] Specifically, both the first drive assembly 400 and the second drive assembly 500 include a drive motor 401 and a drive screw 402 connected to the output end of the drive motor 401. The first drive assembly 400 can drive the first mounting frame 200 to move downward along the support frame 101, cooperating with the rotation of the mixing pile 300 to make it drill into the soft soil. The second drive assembly 500 can drive the second mounting frame 201 to move longitudinally along the first mounting frame 200, thereby adjusting the longitudinal position of the mixing pile 300.
[0021] Furthermore, two sets of second mounting brackets 201 are symmetrically arranged, and the second drive assembly 500 is connected between the two sets of second mounting brackets 201 through a connecting plate 501, and the connecting plate 501 is a telescopic structure.
[0022] Furthermore, the third drive assembly 600 is a drive cylinder 602 connected to the inside of the first mounting frame 200 via a mounting plate 601. The output end of the drive cylinder 602 is connected to a fixing plate 603, which is connected to the bottom of the second mounting frame 201. Two sets of drive cylinders 602 and the second mounting frame 201 are symmetrically arranged to cooperate with each other. In use, by starting the drive cylinder 602, the fixed plate 603 connected to its output end is moved, which can drive the second mounting frame 201 connected to it to move laterally along the first mounting frame 200, thereby adjusting the lateral position of the mixing pile 300.
[0023] It is worth noting that, in order to improve the stability of the first mounting bracket 200 and the second mounting bracket 201 when they move, the first mounting bracket 200 and the support bracket 101, as well as the second mounting bracket 201 and the first mounting bracket 200, are slidably connected by a connecting sleeve 202.
[0024] It is worth noting that, in order to ensure the feasibility of drilling the mixing pile 300, a through groove 103 is provided on the support base plate 100, so that the mixing pile 300 can be lowered and drilled normally.
[0025] The drive motor 401 and drive cylinder 602 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.
[0026] Working Principle: When using this soft soil foundation treatment device: Move the device to the soft soil foundation to be treated. Adjust the spacing or relative position of the mixing piles 300 according to specific construction requirements. During adjustment, activate the second drive assembly 500 to move the second mounting frame 201 longitudinally along the first mounting frame 200, thereby adjusting the longitudinal position of the mixing piles 300. Activate the drive cylinder 602 to move the fixed plate 603 connected to its output end, which in turn moves the second mounting frame 201 laterally along the first mounting frame 200, thus adjusting the longitudinal position of the mixing piles 300. The lateral position is adjusted to adjust the spacing and position of the mixing piles 300 according to the specific construction environment and construction requirements. After adjustment, the first drive component 400 can drive the first mounting frame 200 to move downward along the support frame 101, and the mixing pile 300 drive device drives it to rotate spirally. At the same time, the curing agent inside the storage box 700 is delivered to the mixing pile 300 through the delivery hose through the external drive component and then sprayed into the soft foundation. The mixing pile 300 is then used to mix and achieve the effect of curing.
