Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transmission engineering technology, and in particular to a flood control and diversion dam for the foundation of a power transmission line tower. Background Technology
[0002] With the widespread construction of new energy power generation projects in recent years, project sites have become increasingly remote, resulting in longer grid connection distances for transmission towers. Equipment and tower sites located at the foot of mountains or on mountain ridges are constantly exposed to the risk of erosion from rainfall runoff during initial construction and operation, easily leading to foundation leakage and tower collapse. Current technology primarily involves on-site casting of diversion dams upstream of the foundation. The outer surface of these existing diversion dams is an inclined plane; when encountering flash floods, overtopping and edge seepage frequently occur. Overtopping occurs when the water head is too high, overflowing the diversion dam and entering the foundation construction area, causing foundation erosion and water damage. Edge seepage occurs when flash floods erode the foundation through the edges of the diversion dam, causing further erosion and water damage. Furthermore, the lack of early warning and timely water removal in mountainous areas poses a threat to the safe operation of equipment foundations. Utility Model Content
[0003] In view of this, the present invention provides a flood control diversion dam for the foundation of a transmission line tower. The main purpose is to solve the problems of overflow at the top and seepage around the sides of the existing diversion dam.

Detailed Implementation
[0038] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0039] like Figures 1 to 5 As shown in the figure, an embodiment of the present invention provides a flood control diversion dam for a transmission line tower foundation, comprising: a first diversion component 1 and a second diversion component 2; the cross-section of the first diversion component 1 is a single concave arc curve quadrilateral with a vertical side; the single concave arc curve quadrilateral is composed of a top straight segment 1-2, a bottom straight segment 1-4, a waist straight segment 1-3, and an arc 1-5; the top straight segment 1-2 and the bottom straight segment 1-4 are parallel to each other; the length of the bottom straight segment 1-4 is greater than the length of the top straight segment 1-2; one end of the waist straight segment 1-3 is connected to one end of the top straight segment 1-2; the other end of the waist straight segment 1-3 is connected to one end of the bottom straight segment 1-4. The waist straight segment 1-3 is perpendicular to the bottom straight segment 1-4; one end of the arc 1-5 connects to the other end of the top straight segment 1-2; the other end of the arc 1-5 connects to the other end of the bottom straight segment 1-4; the bottom of the arc 1-5 is concave towards the waist straight segment 1-3; the distance between the bottom of the arc 1-5 and the waist straight segment 1-3 is smaller than the length of the top straight segment 1-2; the arc 1-5 forms a guide channel on the outside of the first guide member 1; the upper end of the guide channel protrudes outward from the middle of the guide channel; when the water head is too high in the direction of incoming water, the water is guided by the arc-shaped guide channel with an outward opening, so that the water falls back into the incoming water flow. One end face of the first guide member 1 has a predetermined angle with the outer edge of the first guide member 1; the predetermined angle is 35°-45°, so as to protect the outer perimeter of the iron tower foundation 4 upstream of the iron tower foundation 4, and to guide the water flow through both sides of the iron tower foundation 4. The end face of the first flow guide member 1 is provided with a dovetail connecting groove 1-1 to facilitate connection with the second flow guide member 2.
[0040] The first guiding component 1 includes: a guiding end 1-6, a guiding middle part 1-7, and a guiding tail 1-8; the guiding end 1-6, the guiding middle part 1-7, and the guiding tail 1-8 are arranged sequentially end to end; the tops of the guiding end 1-6, the guiding middle part 1-7, and the guiding tail 1-8 are all planar structures and are flush with each other; the bottoms of the guiding end 1-6, the guiding middle part 1-7, and the guiding tail 1-8 are all planar structures and are flush with each other; the width of the cross-section of the guiding end 1-6 gradually widens as it extends from the guiding middle part 1-7 to the end face of the guiding end 1-6; the guiding end 1-6 provides support for the connection between the first guiding component 1 and the second guiding component 2; increasing the size of the guiding end 1-6 helps to increase the reliability of the connection between the first guiding component 1 and the second guiding component 2.
[0041] The extended baseline of the guide tail 1-8 is arc-shaped; extending from the middle guide 1-7 to the end of the guide tail 1-8, the guide tail 1-8 is an outwardly convex arc shape. When flash floods scour the interior of the tower foundation 4 through the edges of the diversion dam, the guide tail 1-8 with its outward curvature extends the diversion zone, allowing the incoming water to flow quickly through the scourable area, preventing water scouring and damage to the interior of the tower foundation 4, and protecting the tower foundation 4 within the construction area.
[0042] The guide end 1-6, the guide middle 1-7 and the guide tail 1-8 are integrated and can be formed by pouring reinforced concrete, which is conducive to prefabrication; they can be mass-produced in the factory.
[0043] The cross-section of the second flow guide member 2 is the same as that of the first flow guide member 1; the second flow guide member 2 and the first flow guide member 1 are symmetrically distributed; the end face of the second flow guide member 2 is provided with a dovetail connecting protrusion 2-1 to match and connect with the first flow guide member 1; the end face of the second flow guide member 2 fits against the end face of the first flow guide member 1 and is constrained by the dovetail connecting structure; the first flow guide member 1 and the second flow guide member 2 are connected in a "V" shape. Preferably, there are two dovetail connecting grooves 1-1; the two dovetail connecting grooves 1-1 are arranged parallel and spaced apart; there are two dovetail connecting protrusions 2-1; the two dovetail connecting protrusions 2-1 are arranged one-to-one with the two dovetail connecting grooves 1-1, and the connection is made by the two dovetail structures, which can ensure the connection strength and reliability of the first flow guide member 1 and the second flow guide member 2.
[0044] One embodiment of this utility model proposes a flood control diversion dam for transmission line tower foundations, which can solve the problems of overflow at the top and seepage around the sides of existing diversion dams. It can be installed using prefabricated components, which are then assembled on-site, facilitating construction. During use, a portion of the dam can be buried below ground level. This embodiment of the utility model also reduces the volume of concrete required, and the prefabricated components are less expensive, thus lowering construction costs and shortening the construction period.
[0045] In a preferred embodiment of this utility model, a flood control diversion dam for a transmission line tower foundation is provided, which further includes: two fixed piles 3; the two fixed piles 3 are respectively set on the inner side of the diversion tail 1-8 and the corresponding position of the second diversion component 2, so as to restrict the position of the flood control diversion dam and prevent it from moving as a whole.
