Embodiment Construction
[0040] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0041] Such as Figure 1-Figure 14 As shown, the construction method of the revetment prefabricated hanging board of the present invention is used to install the spliced revetment prefabricated hanging board 1 on the bank of the open channel.
[0042] The side of the revetment prefabricated siding 1 is provided with a convex part 2 or a concave part 3 for splicing connection with the adjacent revetment prefabricated siding 1 , and the top of the revetment prefabricated siding 1 is provided with a lifting ring 4 and an anchoring steel bar 11 . The convex part 2 and the concave part 3 are used for splicing connection with the adjacent revetment prefabricated siding 1, and their size and shape are similar, and can be plu...

The invention relates to a revetment prefabricated hanging plate construction method. The method includes the following steps that firstly, an excavator is used for lifting a first prefabricated hanging plate to the position above the foundation; secondly, the excavator and a tool catcher are used for pressing the bottom of the first prefabricated hanging plate into the foundation; thirdly, the excavator is used for lifting a second prefabricated hanging plate to the side edge of the first prefabricated hanging plate, the excavator and the tool catcher are used for pressing the bottom of the first prefabricated hanging plate into the foundation, and a gap is reserved between the second prefabricated hanging plate and the first prefabricated hanging plate; and fourthly, the side edge of the first prefabricated hanging plate and the side edge of the second prefabricated hanging plate are spliced together through a wrench. According to the revetment prefabricated hanging plate construction method, the excavator is used for lifting the prefabricated hanging plates in place and embedding the prefabricated hanging plates into the foundation under controllable static pressure; and the method is simple and practical, operability is high, cost is low, safety and reliability are achieved, the speed is high, the construction period can be greatly shortened, and good economic benefits and social benefits can be obtained.
Description
technical field [0001] The invention relates to the field of open channel bank construction, in particular to a construction method for revetment prefabricated hanging boards. Background technique [0002] In the construction of sponge city, in the reconstruction of open channels and river banks, due to the site and other reasons, the revetments are designed as interval bored piles for slope protection, and prefabricated concrete slabs, that is, prefabricated hanging slabs, are hung outside as revetment finishes. When the prefabricated hanging slab is installed, it must be pressed into the foundation soil by 800mm. After the prefabricated hanging slab is installed, the cast-in-place concrete crown beam is used to connect the cast-in-place pile and the prefabricated hanging slab, and an expansion joint is set every 15m. The original design of the prefabricated siding boards is 1500mm wide and weighs 2.0t. A 10mm assembly joint is left between the prefabricated siding boards i...
