Background

The revetment is an engineering measure of artificial reinforcement on the original coast bank slope, and is used for defending against the invasion and the elutriation of waves and water currents and the action of underground water and maintaining the stability of a bank line. The outside is acted by waves and water flow, and the inside is also acted by soil pressure and underground water pressure. Vertical hard revetment is a common form of revetment, and a wall structure of the vertical hard revetment can resist scouring attack of water waves, provide reliable bearing capacity and maintain safe use of the whole revetment. And can also build the requirement that people can be hydrophilic in a close range on the bank, so the method is widely applied to the environment of the city along the river. During construction, a pile foundation erected at the edge of a water bank is used as a foundation, a bearing platform and a pier stud are arranged above the pile foundation, finally, a crown beam is connected above the pier stud in series, and a retaining plate is laid on the inner side of the pier stud and used for blocking landslide of soil on the bank side.

The bank protection building construction is a construction project operation with long time consumption, great difficulty and high danger degree, and particularly when the concrete of the upright concrete pier column is cast, a full framing scaffold is usually required to be built beside a river bank until the full framing scaffold is above the top of the pier column, then a welded steel reinforcement framework is arranged and tied up, a template and the like are installed, finally the concrete is cast, and the construction of the pier column is completed after the template is solidified and removed for maintenance; after the pouring construction of the pier stud of one section of revetment is completed, the scaffold needs to be dismantled and transported to the next section of revetment construction site, the scaffold is built again, and the construction is repeated. The whole construction efficiency of the revetment is low, and the revetment is time-consuming and labor-consuming.

Disclosure of Invention

The utility model provides a remove assembled revetment mound construction scaffold frame, in the construction of river course revetment, can realize carrying out the construction of pier stud in succession fast, avoids the process of repeated building scaffold frame, has the engineering progress that shortens greatly, and it is convenient to construct, saves construction cost's advantage.
