Description

Technical Field

[0001] The invention relates to the field of construction auxiliary equipment for building sites, in particular to a steel plate assembled mud pool. Background Art

[0002] Mud pools are common construction facilities on construction sites, used to store mud. Traditional mud pools are dug by workers on site, but this method requires excavation into a pool in the early stage and landfill in the later stage, which is slow, labor-intensive, and cannot be recycled, making it less economical.

[0003] In order to overcome the above defects, an assembled mud pool has appeared in the industry. The mud pool consists of four side steel plates and one bottom steel plate. The above steel plates are prefabricated in the factory and transported to the construction site, and then assembled and welded by workers on site. However, the mud pool still has certain defects: first, the above five steel plates are not uniform in size, which makes it difficult to transport. Moreover, when assembling on site, welding is generally required, which makes it difficult to splice and disassemble. After recycling, it is also inconvenient to transport due to the uneven size. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a steel plate assembled mud pool with simple and convenient transportation, assembly and disassembly processes.

[0005] The technical solution of the present invention is to provide a steel plate assembled mud pool, which includes two side plates and two end plates, each end plate includes a first unit plate, and each side plate includes at least two second unit plates;

[0006] Each unit plate includes a steel panel and a top beam, a bottom beam and two columns welded to the inner surface of the steel panel. Each column is a vertical channel steel with an opening facing inward. The two ends of the two beams are welded to the two columns respectively.

[0007] Each column of each first unit plate is screwed to the column of the side of the adjacent second unit plate through a vertical angle steel; the non-side column of each second unit plate is screwed to the column of the adjacent side of the adjacent second unit plate through a vertical T-shaped steel plate; two upper and lower tie beams are welded between the steel cross plate of each T-shaped steel and the steel cross plate of a T-shaped steel directly facing the opposite side plate, and the two tie beams and the two T-shaped steels welded to the tie beams constitute a tie mesh;

[0008] The mud pit also includes a concrete base slab cast in place on the ground.

[0009] Compared with the prior art, the steel plate assembled mud pool adopting the above structure has the following advantages.

[0010] First, the areas of the first unit plate, the second unit plate and the tie mesh are roughly equal, so they can be stacked into a pile of equal cross-section, which is convenient for transportation and storage; moreover, the second unit plate and the first unit plate are quickly screwed together by angle steel, and the adjacent second unit plates are screwed together and a T-shaped steel is clamped at the same time, so the assembly problem of the tie mesh is solved at the same time. In other words, the entire assembly process can be completed by screwing, so the assembly is convenient. Similarly, the disassembly process is also convenient and fast; moreover, the bottom of the mud pool is sealed with concrete. Compared with the five steel plates in the prior art, the present application only has four lateral plates. After omitting the largest steel plate, the workload of transportation and assembly is greatly omitted; more importantly, although the bottom steel plate is omitted and multiple pieces are spliced, the mud pool is subjected to uniform and reasonable force, and a tie mesh is set at a certain distance along the length direction to tie and resist the lateral pressure of the mud on the side wall, thereby enhancing the strength and bearing capacity of the mud pool and increasing the slurry storage capacity of the mud pool.

[0011] As a gain and supplement, each corner of the mud pool is provided with a diagonal brace. When viewed from above, the included angle between the diagonal brace and the side plate or the end plate is 45 degrees; a support foot is welded at the lower end of the diagonal brace, and an anchor bolt is provided on the support foot; an L-shaped support plate for supporting the vertical angle steel is welded at the upper end of the diagonal brace; the above-mentioned diagonal brace serves as an important supplement to the tie mesh, because the mud pool is mainly subjected to outward thrust on the side plates, and for the second unit plate located on the side, all non-side columns are tied and fixed by the tie mesh, and only the two side columns at the head and the tail lack inward support, and the diagonal brace just supports the angle steel, providing inward support for the side columns of the second unit plate; of course, when viewed from above, the included angle between the diagonal brace and the side plate or the end plate is 45 degrees, so while providing inward support to the side plates, it also provides inward support to the end plates. In other words, the strength and bearing capacity of the mud pool are improved in all directions, and the slurry storage capacity of the mud pool is further increased.

[0012] As a further benefit, an L-shaped rubber plate is provided outside the L-shaped support plate; thus, the friction between the inner end of the diagonal support and the angle steel is increased, so that it obtains a better supporting effect, and further increases the strength and bearing capacity of the mud pool.

[0013] Preferably, the bottom surface of the bottom beam is higher than the bottom surface of the steel panel, and the bottom surface of the bottom beam is flush with the top surface of the concrete bottom plate; in this way, the concrete bottom seal is ensured to be firm and dense, while avoiding the bottom beam from being anchored into the concrete, ensuring easy disassembly. The unit plate with the bolts removed can be separated from the concrete bottom plate by simply bending it outward.

[0014] As another preferred embodiment, a middle beam is welded to the inner surface of the steel panel, and both ends of the middle beam are respectively welded to the two columns of the steel panel; a row of reinforcing ribs are welded between the top beam and the middle beam, and a row of reinforcing ribs are also welded between the middle beam and the bottom beam, and all the reinforcing ribs are welded to the inner surface of the steel panel; in this way, a firm and mutually connected beam-column frame is welded inside the unit plate, which further improves the strength of the unit plate, thereby ensuring the firmness and slurry storage capacity of the mud pool.

[0015] As another preferred embodiment, the tie mesh also includes a tie beam located in the middle and multiple vertical tie bars, and each tie bar is welded to the upper, middle and lower tie beams; in this way, the overall strength of the tie mesh is improved, thereby improving the ability of the two side plates to resist the mud side pressure.

[0016] Also preferably, a side groove is provided on each side of the steel panel of each unit plate; a first sealing strip is provided at the connection node of two adjacent second unit plates, and the first sealing strip is clamped in two mutually adjacent side grooves of the above-mentioned two adjacent second unit plates; two second sealing strips are provided at the connection node between the first unit plate and the adjacent second unit plate, one second sealing strip is pressed by the angle steel of the connection node in the side groove of the first unit plate on the side of the node, and the other second sealing strip is pressed by the angle steel of the connection node in the side groove of the second unit plate on the side of the node; the above-mentioned sealing structure is easy to assemble and has a better sealing effect, which can effectively prevent leakage of mud pool.
