Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a reinforcement structure for a sump and a precast brick formwork of a deep foundation cap. Background Art

[0002] When constructing the foundation slab foundation cap, wooden forms are generally used as the side forms of the foundation cap, and the erection of the side forms of the foundation cap is rather inconvenient. In order to improve the construction efficiency, finished brick formworks have emerged and can be used to replace the side forms of the foundation cap.

[0003] At present, the finished brick formworks of the prior art are for standardized production, with a thickness of 10 cm and a height of 60 cm. When the depth of the foundation cap exceeds 60 cm, the brick formworks need to be spliced. Since the brick formworks are thin and the splicing height is too high, it is easy to cause the collapse of the brick formworks, leading to construction quality and safety problems. The deeper the foundation cap, the higher the construction risk of the brick formworks.

[0004] Therefore, based on the above problems, we have designed a reinforcement structure for a sump and a precast brick formwork of a deep foundation cap to solve the problem of easy collapse of the spliced brick formworks in the deep foundation cap in the prior art. Content of the Utility Model

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a reinforcement structure for a sump and a precast brick formwork of a deep foundation cap, and this reinforcement structure for a sump and a precast brick formwork of a deep foundation cap solves the technical problem of easy collapse of the spliced brick formworks in the deep foundation cap in the prior art.

[0006] To achieve the above object, according to an embodiment of the first aspect of the utility model, a reinforcement structure for a sump and a precast brick formwork of a deep foundation cap is provided, including a foundation pit and a sump arranged in the middle of the foundation pit;

[0007] It further includes:

[0008] A reinforcement structure arranged in the foundation pit and in contact with the side wall of the sump;

[0009] Wherein, the reinforcement structure includes precast slab brick formworks, backfilled plain soil and concrete pressing plates;

[0010] The precast slab brick formworks, backfilled plain soil and concrete pressing plates are provided in multiple layers. Each layer of the backfilled plain soil is arranged outside the precast slab brick formworks, and each layer of the concrete pressing plates is arranged on the top surfaces of the backfilled plain soil and the precast slab brick formworks.

[0011] Further improvement lies in that the lower backfilled plain soil and the precast slab brick formworks are located at the bottom surface of the adjacent upper concrete pressing plates.

[0012] Further improvement lies in that after the multi-layer precast brick formwork, backfilled plain soil and concrete pressing plates are laid, a concrete top pressing plate is arranged above the top-layer backfilled plain soil and precast brick formwork.

[0013] Further improvement lies in that the top-layer concrete pressing plate is located on the surface of the top-layer backfilled plain soil and on the side of the top-layer precast brick formwork.

[0014] Further improvement lies in that the overall shape of the foundation pit is an inverted trapezoid.

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

[0016] For the reinforcement structure of the sump and deep pile cap precast brick formwork of the present utility model, by adjusting the vertical placement of the precast brick formwork to a flat placement, the thickness of the brick formwork is increased, and at the same time, the splicing process of the brick formwork is cancelled, improving the construction efficiency and reducing the safety risks existing in the construction process of the sump and deep pile cap.

[0021] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 and Figure 2 shown, a reinforcement structure of a sump and deep pile cap precast brick formwork includes a foundation pit 2, a sump 21 arranged in the middle of the foundation pit 2, and a reinforcement structure 1 arranged in the foundation pit 2 and in contact with the side wall of the sump 21;

[0023] Among them, the reinforcement structure 1 includes a precast brick formwork 13, backfilled plain soil 11 and a concrete pressing plate 12, and the overall shape of the foundation pit 2 is an inverted trapezoid;

[0024] Specifically, there are multiple layers of precast slab brick formwork 13, backfilled plain soil 11 and concrete pressing plates 12. Each layer of backfilled plain soil 11 is arranged outside the precast slab brick formwork 13, and each layer of concrete pressing plate 12 is arranged on the top surface of the backfilled plain soil 11 and the precast slab brick formwork 13;

[0025] Specifically, the lower backfilled plain soil 11 and the precast slab brick formwork 13 are located at the bottom surface of the adjacent upper concrete pressing plate 12;

[0026] Specifically, after the multiple layers of precast slab brick formwork 13, backfilled plain soil 11 and concrete pressing plates 12 are laid, a concrete top pressing plate 3 is arranged above the top-layer backfilled plain soil 11 and the precast slab brick formwork 13;

[0027] Specifically, the top-layer concrete pressing plate 12 is located on the surface of the top-layer backfilled plain soil 11 and on the side surface of the top-layer precast slab brick formwork 13.

[0028] When implementing this embodiment, this application document only improves the defect that the brick formwork splicing in the deep caisson is prone to collapse in the prior art and does not involve other aspects. In addition, it should be noted that the reinforcement structure 1 in the application document is constructed based on the following construction method;

[0029] The construction method of a kind of reinforcement structure for a sump and a deep caisson precast brick formwork is introduced as follows:

[0030] The first step: The on-site construction personnel first excavate the sump and deep caisson parts on the construction site ground until the earthwork is excavated to the design elevation, then position and set out the caisson or sump side line, and lay the bottommost precast slab brick formwork 13. Every 10 pieces of this precast slab brick formwork 13 are laid, that is, the precast slab brick formwork 13 with a height of 90 cm.

[0031] The second step: After laying the precast slab brick formwork 13, backfill the plain soil 11 outside the precast slab brick formwork 13. The thickness of the backfilled plain soil 11 in layers is controlled at 30 cm, and the height of each backfill of the plain soil 11 is the same as the height of the laid precast slab brick formwork 13;

[0032] The third step: After backfilling the plain soil 11, pour a C20 concrete pressing plate 12 on the backfilled plain soil 11 and the precast slab brick formwork 13 for capping. The thickness of the concrete pressing plate 12 is controlled at 15 cm, and a single-layer bidirectional steel mesh with 16*200 is arranged inside. Wait until the concrete strength reaches 50% of the design strength and then carry out the next cycle until the entire reinforcement structure 1 is completed. Finally, pour a C20 reinforced concrete top pressing plate 3 on the overall reinforcement structure 1 for capping and also serving as the bottom slab cushion, and the top elevation of the plate is the bottom elevation of the bottom slab.

[0033] Through the above design, the precast slab brick formwork 13 is laid flat as the side formwork of the catch basin and the deep foundation cap. Compared with the traditional layout method of the precast slab brick formwork 13, the thickness of the precast slab brick formwork 13 is increased, and at the same time, the splicing of the precast slab brick formwork 13 is avoided, which can greatly reduce the safety risks existing in the construction process of the catch basin and the deep foundation cap.

[0034] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
