All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.
[0029] The following combination Figure 1-5 The specific embodiment of the utility model is described, which is a self-weight collapsible loess foundation reinforcement structure for low-rise civil buildings, comprising:
[0030] The reinforcement assembly 1 includes a reinforcement sleeve 11, wherein a scraper 12 is provided inside the reinforcement sleeve 11, and the scraper 12 is sleeved inside the reinforcement sleeve 11, and one side thereof is open. A seepage hole 111 is provided at one end of the reinforcement sleeve 11, and the seepage hole 111 is communicated with the interior of the scraper 12. A suction pipe 14 is provided inside the scraper 12. The reinforcement sleeve 11 is positioned in the loess to provide lateral support to the loess layer. Since one side of the scraper 12 is open, the fluid inserted into the loess flows into the scraper 12 through the seepage hole 111. A suction pipe 14 is provided in the scraper 12. The fluid retained in the scraper 12 is extracted through the suction pipe 14 to reduce the water content in the soil layer, and a waterproof layer is laid. The waterproof layer can be a waterproof steel coil or a waterproof coating to prevent the fluid from seeping into the soil layer and to prevent the collapse of the soil layer.
[0031] A connecting assembly 2, used for hinged connection between two adjacent reinforcement sleeves 11;
[0032] The tension support assembly 3 is used for connecting the two relative reinforcement sleeves 11. The two ends of the tension support assembly 3 are respectively connected to a reinforcement sleeve 11. The tension support assembly 3 is used for supporting or pulling between the two reinforcement sleeves 11 to avoid mutual inclination between the two reinforcement sleeves 11. The tension support assembly 3 includes a screw 32 and an adjusting sleeve 33. One end of the screw 32 is connected to the reinforcement sleeve 11, and the adjusting sleeve 33 is threadedly connected to the screw 32. The adjusting sleeve 33 is matched with the threads of the two relative screws 32 to rotate the adjusting sleeve 33 to change the distance between the two screws 32, thereby realizing the pulling or support between the two reinforcement sleeves 11.
[0033] Please refer to Figure 2 As shown, the height of the scraper 12 is lower than the height of the reinforcement sleeve 11, and a retention cavity 13 is formed between the bottom of the scraper 12 and the bottom of the reinforcement sleeve 11. A filter hole 122 is provided at the bottom of the scraper 12, and one end of the suction pipe 14 passes through the bottom of the scraper 12 and extends into the retention cavity 13. After the fluid enters the scraper 12 through the seepage hole 111, since the filter hole 122 is provided at the bottom of the scraper 12, the filter hole 122 can filter the muddy water to prevent excessive mud blocks from falling into the retention cavity 13, thereby preventing damage to the pump body during extraction. The filtered mud blocks are carried out of the reinforcement sleeve 11 when the scraper 12 is removed.
[0034] Please refer to Figure 1-Figure 3 As shown, a stopper 121 is provided on the top of the scraper 12, and the stopper 121 is fixedly connected to the scraper 12. The scraper 12 abuts against the top of the reinforcement sleeve 11 through the stopper 121. The outer diameter of the stopper 121 is slightly larger than the outer diameter of the scraper 12, so that the scraper 12 can be sleeved in the reinforcement sleeve 11 and abut against the top of the reinforcement sleeve 11 through the stopper 121.
[0035] Please refer to Figure 1-Figure 3 As shown, a hook 123 is provided at one end of the stop block 12 away from the scraper 12, and the hook 123 is fixedly connected to the scraper 12. The hook 123 facilitates the pulling out of the scraper 12 in the reinforcement sleeve 11. In the process of the scraper 12 moving out of the reinforcement sleeve 11, the bottom of the scraper 12 fits tightly with the side wall of the reinforcement sleeve 11. During the movement of the bottom of the scraper 12, the soil on the side wall of the reinforcement sleeve 11 is scraped, so that the mud or mud blocks that cannot be extracted are moved out of the reinforcement sleeve 11 through the scraper 12.
[0036] Please refer to Figure 4 As shown, the connection component 2 includes
[0037] A U-shaped groove 21 is used to clamp the reinforcement sleeve 11. A reinforcement sleeve 11 can be embedded in the U-shaped groove 21. The U-shaped groove 21 is used to connect two adjacent reinforcement sleeves 11;
[0038] The baffle 22 is fixedly connected to the U-shaped groove 21, and its height matches the height of the reinforcement sleeve 11. The baffle 22 is used to reduce the spacing of the joints formed by the connection between two adjacent reinforcement sleeves 11 to prevent mud from leaking along the joints;
[0039] There are two U-shaped grooves 21, which are hinged between each other. A reinforcement sleeve 11 is clamped in each U-shaped groove 21, which is used for splicing two adjacent reinforcement sleeves 11, and an angle can be formed between the two adjacent reinforcement sleeves 11 to meet the corner construction requirements of the foundation.
[0040] Please refer to Figure 4 As shown, the U-shaped groove 21 is provided with a fixing bolt 23, and the fixing bolt 23 is used for fixing the U-shaped groove 21 and the reinforcement sleeve 11 so that the U-shaped groove 21 and the reinforcement sleeve 11 are locked and fixed to each other.
[0041] Please refer to Figure 1 、 Figure 5 As shown, the tension support assembly 3 also includes a universal joint 31, one end of the universal joint 31 is fixedly connected to the reinforcement sleeve 11, and the other end is fixedly connected to the screw 32. The universal joint 31 meets the connection requirements of any angle between two adjacent reinforcement sleeves 11.
[0042] Please refer to Figures 1-4 As shown, the adjusting sleeve 33 is used for the threaded connection between the two relative screw rods 32. The thread directions of the two relative screw rods 32 are opposite. An adjusting bolt 34 is fixed on the adjusting sleeve 33. Since the distribution directions of the threads on the two relative screw rods 32 are opposite, by rotating the adjusting sleeve 33, it is forced to synchronize thread engagement with the two screw rods 32, thereby changing the distance between the two screw rods 32 and realizing the support connection between the two relative reinforcement sleeve plates 11.
[0043] Working principle of this utility model:
[0044] In the reinforcement method of loess foundation, firstly, structural reinforcement measures are adopted to strengthen the structural integrity of the soil layer, then waterproofing measures are adopted to solve the water seepage problem from the source, and finally foundation measures are adopted to replace the collapsible loess under the foundation.
[0045] In the reinforcement structure, by positioning and installing the reinforcement sleeve 11 in the soil layer, multiple reinforcement sleeves 11 can be continuously connected on both sides of the reinforcement sleeve 11 through the connection component 2. At the same time, several reinforcement sleeves 11 can be positioned on the opposite side of the reinforcement sleeve 11 to enclose the soil layer to prevent the soil layer from expanding or flowing outward. Among them, in the connection between two adjacent reinforcement sleeves 11, the two U-shaped grooves 21 are hinged, and the U-shaped groove 21 can be used to insert the reinforcement sleeve 11, and the baffle 22 fixed on the U-shaped groove 21 is used to reduce the joint formed by the connection between the two reinforcement sleeves 11 to prevent mud from passing through the joint. Leakage, in the connection between the two relative reinforcement sleeves 11, the two relative reinforcement sleeves 11 are supported and connected by the tension support assembly 3, wherein the reinforcement sleeve 11 is fixedly connected with a screw rod 32 by a universal joint, and the screw rod 32 is respectively threadedly connected with an adjustment sleeve 33. Since the threads on the two relative screw rods 32 are distributed in opposite directions, the adjustment sleeve 33 is synchronously threadedly connected with the two relative screw rods 32, thereby realizing the rotation of the adjustment sleeve 33 while driving the two screw rods 32 to move closer to or away from each other, thereby changing the distance between the two reinforcement sleeves 11, and realizing the support connection between the two relative reinforcement sleeves 11;
[0046] Before the reinforcement sleeve 11 is positioned to the soil layer, a scraper 12 is sleeved into the reinforcement sleeve 11. The scraper 12 abuts against the reinforcement sleeve 11 through the stopper 121 at its top, so that a retention cavity 13 is formed between the bottom of the scraper 12 and the bottom of the reinforcement sleeve 11. A plurality of seepage holes 111 are provided on one side of the reinforcement sleeve 11. Since one end of the scraper 12 is open, the mud in the soil layer leaks into the scraper 12 through the stopper 121. The bottom of the scraper 12 is provided with a filter hole 122, and the mud is filtered through the filter hole 122 to prevent the suction pipe 14 or the suction pump body from being blocked by too large mud blocks. The filtered fluid is pumped out of the retention cavity 13 through the suction pipe 14 and the suction pump body, and the substances that cannot be filtered are retained in the scraper 12.
[0047] Excavate the soil within the enclosed reinforcement sleeve 11, remove the excess mud layer, and lay a waterproof layer on the excavated soil layer to prevent fluid from seeping in;
[0048] Before laying the waterproof layer, install underground pipes, and fix the structural columns and ring beams to enhance the integrity of the structure and reduce uneven settlement caused by expansion, subsidence, and earthquakes.
[0049] Replace the soil layer, backfill the upper layer of the waterproof layer with gray soil, and compact the gray soil to ensure that the compaction coefficient is not less than 0.95. Then backfill the indoor core soil with plain soil, and the compaction coefficient is not less than 0.94. Finally, lay a concrete layer on top of the compacted backfill soil layer to achieve reinforcement of the soil layer.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0051] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
