Description

Technical Field

[0001] The utility model relates to the technical field of stepped replacement foundation, in particular to a stepped replacement foundation device for loess geology. Background Art

[0002] The stepped replacement foundation device for loess geology is an improved foundation technology used under loess geological conditions. Its main feature is to place a certain thickness of sand and gravel concrete filler between the original soil layers of the foundation to form a layer of stepped structure to improve the bearing capacity and stability of the foundation. This device is usually used to deal with situations where the soil layer is relatively loose and the bearing capacity is low in loess geological areas. By adding fillers and changing the soil layer structure, the bearing capacity of the foundation can be effectively improved.

[0003] When in use, the traditional device drives the scraper to move downward through the working plate, so that the scraper drives the mixing roller to move downward synchronously until the scraper and the mixing roller enter the foundation, and are driven to move horizontally, so that the loess and sediment inside the foundation can be mixed and paved, thereby increasing the bearing capacity of the foundation, reducing foundation settlement and deformation, and ensuring the safety and stability of the building; however, it is inconvenient to support the working plate during use, which requires the user to support it for a long time, increasing the user's labor intensity and labor burden. In addition, long-term support of the working plate requires workers to continuously monitor and adjust, which may affect work efficiency and extend the construction period. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The utility model provides Figure 1 , Figure 2 and Figure 3 The step-shaped foundation replacement device for loess geology shown in the figure includes: a working plate 1, a driving motor 5 is fixed to one side of the working plate 1, a threaded rod 6 is connected to the output end of the driving motor 5, a moving block is screwed to the outer wall of the threaded rod 6, a scraper 7 is fixed to the bottom of the moving block, and a mixing roller 4 is arranged at the bottom of the scraper 7.

[0030] As can be seen from the above, when in use, first align the working plate 1 with the foundation that needs to be replaced, and drive the threaded rod 6 to rotate through the driving motor 5. The rotation of the threaded rod 6 drives the moving block to move on its outer wall, and the movement of the moving block drives the scraper 7 to move. The movement of the scraper 7 drives the mixing roller 4 to move synchronously, so that the yellow sand and soil inside the foundation can be effectively mixed, making it more uniform.

[0031] refer to Figure 1 and Figure 4 As shown, the support mechanism 2 is located on both sides of the working plate 1, and the support mechanism 2 is used to support the working plate 1. The support mechanism 2 includes a fixing plate 21 fixed on both sides of the working plate 1 and a support column 22 installed inside the fixing plate 21. An adjustment mechanism 3 for moving the support column 22 is provided between the support column 22 and the fixing plate 21.

[0032] Through the above technical solution:

[0033] When in use, the fixed plate 21 is supported by the support column 22. The support of the fixed plate 21 enables the working plate 1 to be effectively supported without the need for the user to support it for a long time, thereby reducing the labor intensity and labor burden of the user. In addition, it solves the problem that the traditional device requires workers to continuously monitor and adjust the working plate 1 for a long time, which may affect work efficiency and prolong the construction period.

[0034] Furthermore, a support plate 23 is fixed to the bottom of the support column 22, and a plurality of evenly distributed support seats 24 are installed at the bottom of the support plate 23; based on this, the support column 22 is supported by the support plate 23, so that the supporting surface between the support column 22 and the ground is larger, thereby avoiding the support column 22 from tilting. By setting a plurality of support seats 24, the support plate 23 is more stable during operation.

[0035] In addition, refer to Figure 3 , Figure 4 and Figure 5 As shown, the adjustment mechanism 3 includes a plurality of limit holes provided inside the support column 22 and a storage groove provided inside the fixed plate 21, a limit rod 35 is installed inside the storage groove, the limit rod 35 corresponds to the limit hole, a reset mechanism for resetting the limit rod 35 is provided between the limit rod 35 and the fixed plate 21, the reset mechanism includes a spring 33 connected between the limit rod 35 and the storage groove and a control mechanism provided on one side of the fixed plate 21, the control mechanism is used to drive the spring 33 to contract, the control mechanism includes a movable rod fixed on one side of the limit rod 35, the movable rod extends to one side of the fixed plate 21 and is fixed with a control plate 34, and the spring 33 is sleeved on the outer wall of the movable rod.

[0036] Through the above technical solution:

[0037] When in use, pulling the control plate 34 drives the movable rod to move, and the movement of the movable rod drives the limit rod 35 to move, and the movement of the limit rod 35 drives the spring 33 to contract, and the contraction of the spring 33 separates the limit rod 35 from the limit groove. After the limit rod 35 and the limit groove are separated from each other, the movable working plate 1 drives the fixed plate 21 to move, and the movement of the fixed plate 21 causes it to move on the outer wall of the support column 22, so that the height of the working plate 1 can be adjusted. The height of the working plate 1 can be adjusted at any time according to the actual site conditions and the height requirements of the foundation replacement, so as to ensure the smooth progress of the construction, thereby eliminating the need for additional equipment or process changes, saving time and cost, while saving human resources and reducing labor intensity.

[0038] Furthermore, a positioning mechanism for positioning the support column 22 is provided between the support column 22 and the fixed plate 21, and the positioning mechanism includes positioning grooves provided on both sides of the support column 22 and two support rods 32 fixed on the top of the fixed plate 21, and a sliding mechanism for facilitating the sliding of the support column 22 is provided between the two support rods 32 and the positioning grooves. Based on this, the sliding mechanism is supported by the two support columns 22, so that the sliding mechanism slides in the positioning groove, thereby making the support column 22 more stable and not prone to sliding.

[0039] Regarding the above-mentioned sliding mechanism, Figure 4 As shown, the sliding mechanism includes a roller 31 installed between two support rods 32, and the roller 31 cooperates with the positioning groove; based on this, through the movement of the fixing plate 21, the two support rods 32 drive the roller 31 to rotate in the positioning groove, and through the rotation of the roller 31, the sliding of the roller 31 in the positioning groove is more stable.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
