Detailed Description
The applicant finds that the existing flood control screen solves the problem that an aluminum alloy or steel flood control fence is difficult to transport and install in actual engineering, improves the transportation and installation efficiency, and reduces the cost, but in the actual use process, because the flood control screen is directly placed on the ground, the construction operations such as sealing and reinforcing on the ground like the flood control fence are not performed. Therefore, the seepage-proofing effect of the flood control screen is actually closely related to the environment, the seepage-proofing effect is very good on a part of flat ground, but the seepage situation exists on the relatively uneven ground. For this reason, the applicant has made intensive studies and has proposed the following means.
As shown in fig. 1, a relatively flexible fin-type anti-seepage piece is additionally arranged on a relatively rigid body along the extending direction of the flood screen, so that a larger contact area is formed with the ground, the anti-seepage distance (seepage diameter) is prolonged, and the anti-seepage effect is improved.
Specifically, in the case shown in fig. 1, the flood barrier comprises two main parts, i.e., a water-receiving part and a water-receiving part, which are integrally formed, the water-receiving part extending along a side of the water-receiving part by a predetermined length for supporting the entire stability of the flood barrier. In other embodiments, the water receiving part and the water bearing part can adopt other shapes, for example, non-concave-convex reinforcing ribs (or ribs) are adopted, and the non-working surfaces, namely the bottom and the rear vertical surface, of the water receiving part and the water receiving part adopt a planar design. At the place where the stress is concentrated, for example, the connection of the water-bearing part and the water-receiving part, the strengthening treatment is carried out by thickening or the like. And a plurality of reinforcing ribs are arranged on the surfaces of the water bearing part and the water receiving part.
In this embodiment, the fin-type impermeable member is connected to the water-bearing portion by way of a detachable connection. Specifically, the fin-type watertight member extends in the direction in which the flood barrier extends, i.e., the W direction in the drawing, while having a predetermined length in the direction of the water, i.e., the L direction. The contact surface of the fin-shaped anti-seepage part and the water bearing part at least has the sealing strength acceptable in engineering so as to form sealing connection.
In other words, the fin-type anti-seepage element and the flood control screen can be designed separately, and the fin-type anti-seepage element and the flood control screen can be connected and fixed together during operation. Or the design of the fixed type, namely when leaving the factory, the two are fixedly connected in a sealing way, and the device can be directly used when needed.
In this embodiment, the detachable connection means may be one of the following means, or a combination of several means. For example, the edge of the water bearing part is provided with a continuous or discontinuous groove or bulge, and the bulge or the groove is arranged corresponding to the connecting edge of the fin-type anti-seepage piece, so that the two parts can be buckled. Or the edge of the water bearing part is provided with a U-shaped groove facing the incoming water direction to form an upper clamping part and a lower clamping part, and the edge of the fin-type anti-seepage piece is placed in the U-shaped groove and then clamped. Or other forms of snap-fit may be used. In other modes, a magic tape or a double-sided adhesive tape can be adopted to be connected and fixed with the water bearing part. In engineering, an omega-shaped or C-shaped groove can be formed at the edge of the water bearing part, and the fin-shaped anti-seepage piece is sleeved in the groove, or the batten is adopted to fix the fin-shaped anti-seepage piece in the groove. Of course, in addition to the above-mentioned detachable manner, it may be fixed by means such as thermal welding, ultrasonic welding, or riveting, or integrally formed or 3D printed at the time of production.
In a further embodiment, the fin-type anti-seepage piece can be laid on the upper surface or the lower surface of the water bearing part or clamped on the side surface of the water bearing part. The number of the fin type anti-seepage pieces can be 2 or more, and the fin type anti-seepage pieces are arranged in a mutually overlapped mode. That is, the fin barrier may be laminated in two or more layers one on top of the other. One or more layers of fin-type anti-seepage pieces can be superposed on the mutually superposed parts, namely the joints of the adjacent fin-type anti-seepage pieces.
In certain embodiments, the fin-type barrier may be attached to a barrier strip disposed below the water bearing portion and then integrally attached to the edge of the water bearing portion. The seepage-proofing strip and the fin type seepage-proofing piece can be made of the same material or different materials.
In each of the above embodiments, the fin-type barrier should generally be fully laid at least in the portion where the water-bearing portion is grounded, in the direction in which the flood screen extends, i.e., in the direction W. In other words, in each flood protection screen unit, the part of the water bearing part contacting with the ground is connected with the fin-type anti-seepage piece, and the part of the water bearing part overlapped with each other can be paved or not paved with the fin-type anti-seepage piece.
In the embodiment shown in fig. 1, the insertion part of the flood protection screen is located at the edge of the water bearing part, and in order to provide a laying space for the fin-type anti-seepage piece, the insertion part can be arranged inwards, and a relatively flat surface is formed at the outer edge of the water bearing part, so that the connection of the fin-type anti-seepage piece is facilitated, or a design space is provided for the connection of the fin-type anti-seepage piece. The extending end of the water bearing part may be referred to as the extending end of the water bearing part in the direction extending from the water receiving part to one side, and the connection part between the fin-type water-proof member and the water bearing part may be located at the side close to the water receiving part or at the middle part of the water bearing part, and is not limited to the outermost side of the water bearing part. Or, in the above embodiment, the connection space of the fin type anti-seepage piece can be formed from the connection part of the water bearing part and the water receiving part to the free end (the end opposite to the connection end) of the water bearing part through design, and the connection belongs to the connection with the extension end of the water bearing part.
Flood screens with outer and inner edges of unequal length of the water carrying section, such as inner or outer sector shaped flood screens, may be laid in a similar manner.
It should be noted that the detachable manner is only an example, and engineers may select other detachable structures according to actual situations. Thereby making the fin formula prevention of seepage spare can be convenient for install in the water-holding part.
In further embodiments, the fin barrier is generally less dense than water due to its relatively low density. In order to prevent the fin shaped barrier from floating, floating or being flung up, several continuous or intermittent weights are provided on the fin shaped barrier, preferably laid in the W direction, pressing the fin shaped barrier at the outer edge.
In a further embodiment, the lateral edges of the fin barrier extend outwardly, for example along the dotted line portion as shown in fig. 1, to form a segment. When adjacent flood control screens are spliced together, a larger lap joint area is formed in a fan-shaped block overlapping mode, so that the anti-seepage effect is improved.
In other embodiments, multiple flood barriers are sealed together by the same fin-type barrier. That is, one fin-type barrier may be fitted over multiple flood screens to form an integral barrier structure.
It should be noted that the sector is only used as a case, and the sector is a broad term, and can be similar to the sector in form or shape. The term "fan" means that the area extending outward from the edge of the water-receiving portion increases in the direction from the edge of the water-receiving portion, that is, the fan indicates the entire shape, and the shape of the edge is not limited. The edges of the sectors may be straight, curved, laced, or even irregularly shaped, and may extend a predetermined distance to overlap adjacent fin-type barriers.
The inner edge of the fin type anti-seepage part is matched with the edge shape of the water bearing part and can be arc-shaped or linear, and the outer edge can be arc-shaped, linear or irregular.
In a further embodiment, the structure of the fin-type anti-seepage piece mainly comprises a body, and a connecting part and a weight part which are arranged on two sides of the body, and the main body can be rectangular, trapezoidal, fan-shaped or annular, or other polygons, or the whole body is shaped like a rectangle, a trapezoid, a fan-shaped or an annular, and the edge can be shaped in various regular or irregular shapes. On the material, flexible materials required by engineering can be adopted, and the relevant physical parameters of the materials meet the requirements of engineering conditions.
In one embodiment, an adhesive part, a buckling part or a connecting part can be arranged on one side of the main body, and the main body is hermetically connected with the flood control screen to form a complete flood control screen system. In actual production and use, the water-bearing water-retaining device can be installed in a factory, folded above or below the water-bearing part and unfolded in use. Or may be installed at the time of use. For example, the flood screen can be arranged at the rear side of the flood screen, or can be separately arranged and assembled when in use.
Generally, most polymeric materials have a density less than that of water. In the using process, the situation of loose fit with the ground is easy to occur, for example, the situation is flushed by water, so that a plurality of weight parts are required to be arranged at intervals or continuously in the transverse extending direction of the fin-type anti-seepage piece, the weight parts can be arranged at intervals or continuously along the direction parallel to the edge of the water bearing part, or can be arranged along the extending direction L of the fin-type anti-seepage piece, and then the weight parts are arranged at intervals of a predetermined distance. That is, regardless of how the individual weights are distributed, they extend a certain distance in the transverse direction of the flood screen, i.e. in the direction W.
In other words, in engineering, one or more sets of weights arranged in parallel, extending generally in a direction parallel to W, or a plurality of weights arranged in parallel to L, and then spaced apart in the W direction, extending laterally, may be employed. Or in a combined manner. In short, the overall extending direction may be substantially parallel to the connecting direction, i.e., the W direction. The basic purpose is to add weight to the free end of the fin-type barrier and reduce the chance of it being flung up.
It should be noted that the weight portion and the fin-type anti-seepage member may be connected in a fixed or detachable manner, for example, several fastening portions are provided on the fin-type anti-seepage member, and the weight portion is combined when in use. The fin-type anti-seepage piece can also be directly installed in the fin-type anti-seepage piece when the fin-type anti-seepage piece is manufactured. For example, when the fin barrier is attached to the bottom seal, the weights are also installed together at the same time to form a complete barrier system.
In the embodiment shown in fig. 2, the free end of the water-bearing part forms a flat connecting space for connecting with the fin-type anti-seepage part, and in this embodiment, the structure of the fin-type anti-seepage part is not shown.
In a word, this technical equipment in this application has light and handy convenient, the equipment is nimble, strong adaptability, the durability is good, repeatedly usable etc. is showing the advantage, the city waterlogging manger plate scene that is applicable to under the various topography that can be better.
It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the utility model. The utility model is not described in detail in order to avoid unnecessary repetition.
