Problems solved by technology

Since the flexible packing sold in the domestic and foreign markets has viscosity and certain elastoplastic properties, and it is constructed on the steep slope of the dam, manual compaction is not strong enough and compaction is extremely difficult
Therefore, manual compaction of flexible packing is inefficient and the compaction quality is not very satisfactory
[0007] In summary, in order to solve the problems of low compaction efficiency and poor quality of the conventional manual caulking method, the present invention proposes a flexible filler former for the construction of flexible filler in the face joints of concrete face rockfill dams

Embodiment Construction

[0021] Such as figure 1 Schematic diagram of the front elevation of the flexible packing former and figure 2 As shown in the schematic diagram of the side elevation of the flexible packing former, the forming belt 1 is fixed on the fixing part 2 through the fixture 4, and the fixing part 2 is connected with the connecting part 3 through the bearing 5. By loosening the fixture 4, the length of the forming belt 1 in the fixture 2 can be precisely adjusted, and by adjusting the position of the bearing 5 on the connector 3, the distance between the fixtures 2 at both ends can be precisely adjusted, and various clamps can be precisely formed. The shape of the groove surface of the flexible filler can realize the multi-slit type and even multi-project general use of a set of formers.

[0022] The construction diagram of the flexible packing former is shown in image 3 , the flexible filler molding device is located just above the V-shaped groove 9 on the surface of the concrete p...

Abstract

The invention provides a flexible packing former for a concrete face rockfill dam face. The flexible packing former is characterized by comprising a machine body, wherein the machine body comprises forming belts for clamping and pressing flexible packing, fixing parts for fixing the two ends of each forming belt and connecting parts for connecting the fixing parts; slot surfaces for clamping and pressing the flexible packing are formed in the forming belts; the slot surfaces are matched with the outer profile of the cross section of the flexible packing to be embedded and filled or matched with the decomposed cross section of the flexible packing to be embedded and filled in shape; the number of the forming belts is no less than 2; the forming belts are made from materials which are easy to deform and good in tensile strength; such materials which are easy to deform and good in tensile strength are nonmetal materials, such as rubber, leather, plastic and the like, or metal materials, such as copper, aluminum, iron and the like; the connecting parts can be used for adjusting the spacing among the fixing parts; and the fixing parts are provided with fixtures capable of clamping the forming belts. According to the flexible packing former, the problems of low efficiency and low quality in embedding and filling joint materials in jointing and caulking construction of the concrete face rockfill dam face can be effectively solved.

Description

technical field [0001] The invention relates to a construction device, in particular to a flexible filler former used for the construction of flexible filler embedding in the face joints of concrete face rockfill dams. Background technique [0002] Concrete face rockfill dam is a dam form widely used in the construction of hydropower stations at home and abroad, and has become the main comparison or preferred dam type in my country. In the next 10 years, with technological progress, my country will promote the construction of more face rockfill dams. [0003] The concrete face rockfill dam uses the rockfill body as the main force-bearing structure to bear the reservoir water pressure, and the reinforced concrete face plate poured from bottom to top on the facing surface of the rockfill body is the anti-seepage structure. Due to factors such as the settlement and deformation of the dam body, the concrete panels need to be poured in blocks, so that dozens of joints are formed...
