Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and hydropower, and in particular relates to an attached, non-removable formwork flood control wall. Background Technology

[0002] Currently, flood walls are the main flood control engineering units used in river basin flood control systems. Concrete flood walls are usually constructed using cast-in-place methods, which are mature technologies that can guarantee quality. However, the construction method of cast-in-place is relatively complex. In the early stages of construction, formwork support is required on site, resulting in a long construction period. Later, the formwork needs to be dismantled, further extending the construction period. The formwork itself is heavy, making on-site operation extremely inconvenient. This leads to a long construction cycle, surface peeling and flaking during formwork dismantling, and a large amount of space occupied during construction, which are particularly detrimental to flood control systems used in hydropower stations.

[0003] Therefore, it is necessary to develop a cast-in-place process that is convenient for on-site construction, has a simple construction process, and saves construction time; and to ensure the excellent quality of the flood control wall. Based on this, an attached non-removable formwork flood control wall and its construction method are proposed. Utility Model Content

[0004] The purpose of this invention is to provide an attached, non-removable formwork flood barrier and its construction method. By using an attached formwork, the flood barrier pouring construction eliminates the need for formwork erection and removal, and also eliminates the need to address uneven surfaces after formwork removal. This facilitates on-site construction, simplifies the construction process, and saves construction time.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An attached, non-removable formwork flood control wall, the flood control wall comprising a flood control wall foundation and several segments of attached formwork;

[0007] The attached template includes a back panel and a water-facing panel;

[0008] Foundation anchors are installed on the top surface of the flood control wall foundation;

[0009] Anchoring steel bars are provided on the inner side of the back panel and on the inner side of the water-facing panel;

[0010] The back panel and the water-facing panel are set opposite to each other on the foundation of the flood control wall and the foundation anchors are surrounded in the middle to form a cast cavity. The anchoring steel bars of the back panel and the anchoring steel bars of the water-facing panel are fixed together with the foundation anchors.

[0011] The casting cavity is equipped with a wall reinforcement cage that matches the shape of the casting cavity, and concrete is poured into the casting cavity. The poured concrete, together with the back panel and the water-facing panel, forms the flood control wall.

[0012] The back panel and the water-facing panel are positioned opposite each other and secured with continuous bolts. The number of continuous bolts, as well as the arrangement and number of bolt holes on the panels, can be adjusted as needed to ensure the back panel and the water-facing panel are firmly fixed.

[0013] Both the back panel and the water-facing panel are equipped with lifting rings at their top. Preferably, there are two lifting rings, evenly distributed around the lifting center of gravity of the panel. These lifting rings can be installed on the top surface of the panel and pre-embedded during panel prefabrication, or they can be fixed to the panel by bolts through holes. This installation allows for direct lifting to the designated position using a crane during panel assembly, offering convenience without compromising flood control effectiveness.

[0014] The back panel is vertically installed on the foundation of the flood control wall, while the water-facing panel is obliquely installed on the foundation. The back panel is generally a rectangular plate, and the water-facing panel is an angled plate with a vertical section at its connection point to the flood control wall foundation. The back panel and the water-facing panel have the same horizontal length and the same vertical height. A segment of the attached formwork includes one back panel and one water-facing panel; the back panel is vertically installed, and the water-facing panel is obliquely installed, with the two facing each other.

[0015] Between several segments of attached formwork, the back panel and the water-facing panel can be designed with flat sides. When connecting several segments of attached formwork, one back panel is directly connected to another, and so on. At the same time, one water-facing panel is directly connected to another, and so on. After the back panels and water-facing panels are connected, a flood control wall of a certain length is formed.

[0016] For connection between several sections of attached formwork, a mounting plate can be used. The mounting plate can be made of embedded steel plate or some waterproof material plate, such as rigid waterproof rubber plate.

[0017] For several segments of attached formwork, a boss can be provided on one side of the back panel and the water-facing panel, and a groove matching the boss can be provided on the other side. When connecting several segments of attached formwork, the boss of one back panel connects to the groove of another back panel, and so on. At the same time, the boss of one water-facing panel connects to the groove of another water-facing panel, and so on. After the back panel and the water-facing panel are connected, a flood control wall of a certain length is formed.

[0018] Preferably, the foundation anchor is a pre-embedded steel bar.

[0019] Preferably, both the back panel and the water-facing panel are made of precast concrete. This utility model also provides a construction method for the above-mentioned attached, non-removable formwork flood control wall, the construction method comprising:

[0023] 3) The back panel and the water-facing panel are connected and fixed using through bolts through the pre-drilled bolt holes in the panels;

[0024] 4) Use embedded plates to connect the attached formwork of adjacent segments to the waterproof wall foundation; forming a semi-closed structural casting cavity in each segment of the wall with only an opening at the top;

[0025] 5) Pour concrete into the cavity until it is level with the top of the attached formwork; at the same time, vibrate the concrete thoroughly; perform surface curing after pouring the concrete and level the outer surface; cut off the long bolts on the attached formwork. At this point, the construction of one section of the flood wall is completed; complete several sections in sequence to complete the overall construction of the flood wall.

[0026] Optionally, the attached templates of adjacent segments are connected by protrusions and grooves on both sides of the back panel and the water-facing panel, and a waterproof sealing strip is provided at the connection joint; the waterproof sealing strip can be made of a water-swellable sealing material.
