Technical Field

[0001] The utility model relates to the technical field of drainage wells, in particular to a rainfall drainage device for building construction. Background Art

[0002] In construction projects, foundation pit drainage and rainfall drainage, as important contents of engineering construction, are directly related to the safety and bearing capacity of the foundation. As a pipe well for rainfall drainage, it is necessary to combine the bottom water collection and open drainage measures to solve the foundation pit precipitation problem. The current installation process of the drainage pipe well is: first, the drainage well pit is excavated mechanically, and the multiple well rings that constitute the drainage pipe well are hoisted into the drainage well pit in turn by an 8t or 6t truck crane and connected vertically.

[0003] The inner diameter of the above-mentioned drainage pit is only slightly larger than the outer diameter of the well ring. An 8t or 6t truck crane cannot accurately install multiple well rings vertically from bottom to top in the drainage pit in a narrow space. Moreover, the surfaces at both ends of the well rings are flat, and two adjacent well rings cannot be stably connected vertically. Therefore, it is often necessary to manually go down into the drainage pit to vertically connect multiple well rings. This article aims to propose a structure that can guide the coaxial vertical connection of two well rings. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] See attached Figure 1-2A rainwater drainage device for building construction includes a plurality of well rings 1, which are coaxially and vertically connected from top to bottom in sequence. The well rings 1 are tubular in shape as a whole. The well rings 1 are composed of a steel cage 5 and concrete casting. The steel cage 5 is arranged inside the concrete. Positioning grooves 6 are arranged on the inner walls of the lower openings of the plurality of well rings 1, and the upper opening inner rings of the plurality of well rings 1 are fixedly connected with conical positioning rings 4.

[0021] It should be noted that the outer diameter of the top end of the conical positioning ring 4 is much smaller than the inner diameter of the opening at the lower end of the positioning slot 6, that is, the top end of the conical positioning ring 4 can be easily inserted into the positioning slot 6, and the inner cavity of the positioning slot 6 and the outer ring of the conical positioning ring 4 are consistent with each other. The middle part of the outer periphery of the conical positioning ring 4 is a conical surface. The conical surface has the purpose of automatically finding the center, which is conducive to assisting the upper well ring 1 to be coaxially placed on the upper end of the lower well ring 1, that is, the conical positioning ring 4 can be coaxially embedded and installed in the positioning slot 6, mainly used to assist the coaxial docking of two adjacent well rings 1.

[0022] In this embodiment, six steel bars 2 are fixedly installed on the periphery of the uppermost and lowermost well rings 1. The steel bars 2 are T-shaped as a whole. The six steel bars 2 are evenly distributed with the central axis of the well ring 1 as the center of the circle. Pull ropes 3 are bound and installed on the six lower steel bars 2, and the upper ends of the six pull ropes 3 are respectively bound and installed on the six upper steel bars 2.

[0023] According to the utility model, after the drainage pit is dug in the construction site, the inner diameter of the drainage pit is greater than the outer diameter of the well ring 1 by 50 cm, that is, after the well ring 1 is coaxially installed in the drainage pit, a certain gap is reserved between the inner wall of the drainage pit and the outer wall diameter of the well ring 1 for backfilling with crushed stone or mortar. The backfilled crushed stone or mortar supports a plurality of well rings 1 from the outside of the well ring 1 to prevent the plurality of well rings 1 installed vertically from being deformed or collapsed. The construction process of the plurality of well rings 1 is as follows:

[0024] 1) First, one end of the six pull ropes 3 is fixedly bound to the six steel bars 2 on the periphery of the bottom well ring 1, and then the bottom well ring 1 is stably placed on the inner bottom surface of the drainage well pit by the six pull ropes 3 using a car crane, and the conical positioning ring 4 is placed upward. After the bottom well ring 1 is placed, the installation direction of the well ring 1 can be adjusted by manually pulling the upper ends of the pull ropes 3 at different positions outward, and the opening of the bottom well ring 1 is vertically facing upward. Then, along the inner wall of the drainage well pit, mortar is filled to the periphery of the well ring 1, and the well ring 1 is vertically and stably installed in the drainage well pit, that is, the well ring 1 in the drainage well pit can be adjusted above the ground by the six pull ropes 3;

[0025] 2) After the mortar filled on the outer periphery of the lowermost well ring 1 solidifies, the remaining well rings 1 are hoisted downwards into the drainage well pit in sequence by the automobile crane, and the well ring 1 with the steel bar column 2 is placed at the last installation, and the positioning card slot 6 below the well ring 1 hoisted into the well pit is sleeved on the conical positioning ring 4 on the lower well ring 1. Through the mutually matching inner cavities of the positioning card slot 6 and the conical positioning ring 4, the upper and lower adjacent well rings 1 can be coaxially connected. If the upper and lower adjacent well rings 1 are not coaxially vertically connected, if the upper well ring 1 is installed tilted, the installation direction of the well ring 1 can be adjusted by manually pulling the upper ends of the pull ropes 3 at different positions outward, and the well ring 1 can be straightened without manual downhole operation to complete the position adjustment of the well ring 1;

[0026] 3) After the several well rings 1 are butt-jointed and straightened, the upper end of the uppermost well ring 1 is higher than the upper opening of the drainage pit, and the upper ends of the six pull ropes 3 are vertically tied to the six steel bars 2 on the periphery of the uppermost well ring 1, so that the several well rings 1 constituting the drainage well are fixedly connected, and the connection between the several well rings 1 can be effectively deformed and tilted;

[0027] 4) After the six pull ropes 3 are installed, gravel is filled toward the periphery of the well ring 1 along the inner wall of the drainage well pit again. The backfilled gravel is used to support several well rings 1 from the outside of the well ring 1 to prevent several well rings 1 installed vertically from deformation or collapse.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
