Description

Technical Field

[0001] This utility model relates to the field of foundation treatment technology, and more specifically, to a preloading device for soft soil foundation treatment. Background Technology

[0002] Soft soil foundations refer to weak soil layers with low strength and high compressibility, often containing a certain amount of organic matter. Due to their low strength and large settlement, soft soil often poses significant risks to road engineering. Improper treatment can severely impact highway construction and use. Current soft soil foundation treatment methods, when construction time permits, often employ surcharge preloading. This involves applying a load to saturated soft soil, causing pore water to slowly drain, reducing pore volume, and inducing consolidation deformation of the foundation.

[0003] Existing stacking methods require the use of a large number of stones or water tanks to be stacked one on top of the other. Since the weight of the stacked items is relatively large, there will be a significant safety hazard if the stacking deviation is too large at the top. Furthermore, the excessive weight makes it inconvenient to move the stacked items. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a preloading device for soft soil foundation treatment that can install multi-layer stacked boxes in place before adding weight.

[0005] A preloading device for soft soil foundation treatment includes: a drainage board disposed within the soft soil foundation and a sand cushion layer laid above the soft soil foundation, the sand cushion layer being surrounded by a drainage ditch; and further includes: a steel plate laid on the sand cushion layer; a support base disposed on the steel plate, the support base including an I-beam and a slide rail; an auxiliary pusher slidably connected to the slide rail; a slack container detachably connected to the auxiliary pusher; a water inlet / outlet mechanism detachably connected to the slack container; and a water collection well disposed between adjacent slack containers.

[0006] Furthermore, multiple I-beams are provided, with adjacent I-beams spaced at the same interval. The slide rails are provided on the top of the I-beams, with two slide rails on the top of each I-beam. The sidewalls of adjacent I-beams are connected by connecting plates.

[0007] Furthermore, the side wall of the connecting plate is provided with multiple slots, which are inserted into the web of the I-beam.

[0008] Furthermore, the auxiliary pusher includes a frame, pulleys, an extension rod, and a baffle. The pulleys are located at the bottom of the frame and are slidably connected to the slide rail. The extension rod can be inserted into the top of the frame, and the baffle is detachably connected to the frame and the extension rod.

[0009] Furthermore, the top of the frame is provided with a connecting hole, and the bottom of the extension rod is provided with a connecting rod, which can be inserted into the connecting hole.

[0010] Furthermore, the two sides of the stacking box are fitted with the baffle, the inside of the stacking box is provided with a partition, the side wall of the stacking box is provided with a water pipe, and the water pipe is provided with a valve.

[0011] Furthermore, the water inlet and outlet mechanism includes a main water inlet pipe, a connecting hose, and a drain branch pipe. The connecting hose is detachably connected to the water pipe and the main water inlet pipe. The drain branch pipe is located on the side wall of the main water inlet pipe and is located in the drainage ditch.

[0012] Furthermore, the end of the connecting hose is provided with a rigid connection part, and a sleeve is provided on the rigid connection part, which can be screwed to the water pipe.

[0013] Furthermore, drainage channels are interspersed in the sand cushion layer, and the water collection well is located at the intersection of the drainage channels, with the bottom of the water collection well being lower than the bottom of the sand cushion layer.

[0014] Furthermore, a wire mesh is provided at the connection between the water collection well and the drainage channel and the water collection well, and a water pump is provided in the water collection well.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] ① Before installing the stacking container, connect the extension rod so that the height of the extension rod is greater than the height of the stacking container after installation. This makes it easier to accurately position the stacking container when hoisting it. The position of the stacking container can also be adjusted by moving the frame. Construction workers can move the upper stacking container by standing on the ground, which increases the safety factor of construction. Attached Figure Description

[0025] 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.

[0026] like Figure 1 As shown, a preloading device for soft soil foundation treatment includes: a drainage board 1 disposed within the soft soil foundation and a sand cushion layer 2 laid above the soft soil foundation, with a drainage ditch 3 surrounding the sand cushion layer 2; a steel plate 4 laid on the sand cushion layer 2; a support base 5 disposed on the steel plate 4, the support base 5 including an I-beam 51 and a slide rail 52; an auxiliary pusher 6 slidably connected to the slide rail 52; a stacking box 7 detachably connected to the auxiliary pusher 6; a water inlet / outlet mechanism 8 detachably connected to the stacking box 7; and a water collection well 9 disposed between adjacent stacking boxes 7.

[0027] After the steel plate 4 is laid on top of the sand cushion layer 2, it facilitates the even distribution of the surcharge pressure from above to all directions of the sand cushion layer 2, maintaining a balanced preloading force. After compaction, water in the soft soil foundation enters the drainage board 1, then the sand cushion layer 2, and finally the drainage ditch 3.

[0028] like Figure 2As shown, multiple I-beams 51 are provided. The I-beams 51 have good load-bearing capacity and are laid on steel plates 4. Adjacent I-beams 51 are spaced evenly, facilitating the positioning of the subsequent stacking box 7. Slide rails 52 are welded to the top of the I-beams 51. Each I-beam 51 has two slide rails 52 at its top. The outer wall of the slide rail 52 fits against the edge of the flange of the I-beam 51. The side walls of adjacent I-beams 51 are connected by connecting plates 53, thus ensuring that the spacing between adjacent I-beams 51 is the same.

[0029] The side wall of the connecting plate 53 is provided with multiple slots 531. The width of the slots 531 is the same as the width of the web of the I-beam 51, and the spacing between adjacent slots 531 is the same. The slots 531 are inserted into the web of the I-beam 51, and the connecting plates 53 are inserted into both ends of the I-beam 51. This restricts the ends of multiple I-beams 51, fixes the spacing between adjacent I-beams 51, and thus fixes the position of the adjacent slide rails 52, which facilitates the positioning of the stacking box 7.

[0030] Stones 54 can be filled between adjacent H-beams 51. After filling with stones 54, the top surface of the stones 54 should be at the same height as the top surface of the slide 52. This greatly reduces the amount of stone used, saving transportation and handling costs and time. Alternatively, construction gravel from the surrounding construction site can be used instead of stones 54, further reducing costs.

[0031] The auxiliary pusher 6 is used for positioning and installing the stacking container 7, and also facilitates the adjustment of the position of the stacking container 7. For example... Figure 3 As shown, the auxiliary pusher 6 includes a frame 61, pulleys 62, extension rods 63, and baffles 64. The pulleys 62 are located at the bottom of the frame 61 and are slidably connected to the slide rail 52. The pulleys 62 facilitate the effortless movement of the frame 61. The extension rods 63 can be inserted into the top of the frame 61. By extending the extension rods 63, the upper stacking boxes 7 can be moved. The baffles 64 are detachably connected to the frame 61 and the extension rods 63. The baffles 64 drive the stacking boxes 7 to move back and forth.

[0032] The distance between the two pulleys 62 is greater than the width of the stacking box 7, and the frame 61 does not contact the stacking box 7. The top of the frame 61 is provided with a connecting hole 611, and the bottom of the extension rod 63 is provided with a connecting rod 631. The connecting rod 631 can be inserted into the connecting hole 611. The top of the extension rod 63 is also provided with a connecting hole 611. By connecting the connecting rods 631 of multiple extension rods 63 with the connecting holes 611, the height can be moved to move the stacking box 7 stacked on top.

[0033] The two sides of the stacker container 7 are fitted with the baffles 64. The frame 61 moves back and forth, causing the baffles 64 to move together. The baffles 64 move the stacker container 7. After the stacker container 7 is in place, the baffles 64 can be pulled out. When moving the upper stacker container 7, the baffles 64 on the lower stacker container 7 will be removed to avoid affecting the lower stacker container 7 during the movement.

[0034] Before installing the stacker container 7, connect the extension rod 63 so that its height is greater than the height of the stacker container 7 after installation. This facilitates accurate positioning when hoisting the stacker container 7. The position of the stacker container 7 can also be adjusted by moving the frame 61. Construction personnel can move the upper stacker container 7 simply by standing on the ground, increasing the safety factor of construction. The weight of the stacker container 7 before water filling can be pushed by the baffle 64.

[0035] like Figure 4 As shown, the slab container 7 has a partition 71 inside, with interconnected through holes. The partition 71 reduces the impact force of water during movement. A water pipe 72 is installed on the side wall of the slab container 7 for filling or draining water. The water pipe 72 has a valve, which is opened during filling and draining to connect the slab container 7 to the outside. Injecting water into the slab container 7 increases its weight, thereby pressing down on the soft soil foundation, causing water in the soft soil foundation to flow out through the drainage plate 1.

[0036] like Figure 5 As shown, the water inlet / outlet mechanism 8 is used to connect the water pipe 72 to fill or drain water from the stacker container 7. The water inlet / outlet mechanism 8 includes a main water inlet pipe 81, a connecting hose 82, and a drain branch pipe 83. The length of the connecting hose 82 is selected according to the maximum height of the stacker container 7. The connecting hose 82 is detachably connected to the water pipe 72 and the main water inlet pipe 81. The drain branch pipe 83 is located on the side wall of the main water inlet pipe 81 and is situated within the drainage ditch 3. Both the drain branch pipe 83 and the main water inlet pipe 81 are equipped with valves. During water filling, the water pump is connected to the main water inlet pipe 81, and the drain branch pipe 83 is closed. During water draining, the valves on the drain branch pipe 83 are opened to accelerate the drainage speed.

[0037] The end of the connecting hose 82 is provided with a rigid connection part 821, and a sleeve 822 is provided on the rigid connection part 821. The sleeve 822 can be screwed to the water pipe 72. It can be quickly disassembled by rotating the screw connection, which is also convenient for construction personnel to operate.

[0038] Drainage channels 21 are interspersed in the sand cushion layer 2. The drainage channels 21 are not located in the same vertical direction as the I-beam 51 to prevent the I-beam 51 from collapsing. The water collection well 9 is located at the intersection of the drainage channels 21. The bottom of the water collection well 9 is lower than the bottom of the sand cushion layer 2. Seepage water from the weak foundation in the middle flows into the water collection well 9, while seepage water from the outer side flows directly into the drainage ditch 3. There is a notch in the steel plate 4 at the water collection well 9.

[0039] like Figure 6 As shown, a wire mesh 91 is provided at the connection between the water collection well 9 and the drainage channel 21 and the water collection well 9. The wire mesh 91 is used to intercept large particles and reduce the amount of debris entering the water collection well 9. A water pump 92 is provided in the water collection well 9 to pump the water in the water collection well 9 into the drainage ditch 3.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
