Problems solved by technology

This method uses the smoothness of the steel formwork to solve the problem of the appearance of the concrete on the exposed surface of the slide pile, but this method has certain limitations: on the one hand, because the customized steel formwork has a certain thickness, the hole diameter of the anti-slide pile excavation needs to be enlarged, resulting in an increase in cost , uneconomical; on the other hand, because the customized steel formwork is poured in the pile hole, the earthwork on one side of the road needs to be excavated before the steel formwork can be taken out for turnover. The turnover of customized steel formwork is greatly restricted and the cost is relatively high
[0005] Or after brushing composite polymer materials and glass fiber and other reinforcing materials on the surface of the formwork, the steel formwork and steel frame plywood formwork can improve the pouring appearance. However, these methods require extremely high levels of materials and construction skills. The cost of construction and realization is also relatively high, and the promotion and application are greatly limited

Abstract

The invention relates to a fair-faced supporting formwork structure on the exposed face of a side slope road cutting manual hole digging slide-resistant pile and a construction technology. The structure comprises a fine aggregate concrete back-ejecta layer, wherein the fine aggregate concrete back-ejecta layer is arranged on the inner side wall of the pile hole of a manual hole digging pile on theexposed side of a slide-resistant pile; a mortar back-ejecta layer is arranged on the surface of the fine aggregate concrete back-ejecta layer; a plastic thin film plate is paved on the inner side wall of the mortar back-ejecta layer; and a plurality of prefabricated cushion blocks bound with rebars of the slide-resistant pile are uniformly distributed on the inner side walls of the plastic thinfilm plate. The fair-faced supporting formwork structure adopts a unique multi-layer structure, is simpler in construction and realizes the purpose that the surface quality of fair-faced concrete on the exposed face of the manual hole digging slide-resistant pile is high.

Description

technical field [0001] The invention relates to the field of road engineering construction, in particular to a clear water support formwork structure and construction technology on the exposed surface of an anti-slide pile with manual digging holes on a side slope cutting. Background technique [0002] In the cutting protection engineering of hilly and mountainous roads, the cutting protection of "anti-slide pile + wall between piles" is often designed. During the construction of the cutting protection project, in order to ensure construction safety, it is often necessary to use manual digging piles for anti-sliding piles. After the hole is formed and the reinforcement cage is placed to pour concrete into the pile, and the pile body reaches the design strength, the earthwork on the side of the road is excavated to ensure that the prefabricated slab wall behind the construction anti-slide pile can support the soil pressure on the side of the cutting. The front and two sides o...
