Combined type lattice form prefabricated pile wall support protecting structure and construction method thereof
The invention discloses a combined type lattice form prefabricated pile wall support protecting structure. The combined type lattice form prefabricated pile wall support protecting structure comprisesa front-row pile wall, a back-row pile wall, middle pile walls, a platform plate and a buttress retaining wall, wherein the front-row pile wall and the back-row pile wall are front and back two rowsof parallel close-packed prefabricated prestress concrete hollow square piles, the middle pile walls are a plurality of rows of close-packed prefabricated prestress concrete hollow square piles vertically located between the front-row pile wall and the back-row pile wall, and cavities of the prefabricated prestress concrete hollow square piles are internally provided with cast-in-place steel bar concrete filling cores. Accordingly, an inventor further establishes a corresponding construction method. By means of the combined type lattice form prefabricated pile wall support protecting structureand the construction method thereof, the defects of the insufficient rigidity and bearing capacity of prefabricated support protecting piles used in deep foundation pit high slopes are overcome, a new solution scheme capable of performing construction rapidly is provided for foundation pit support protecting without support and anchor requirements, the combined type lattice form prefabricated pile wall support protecting structure has the characteristics of saving the construction period, saving the cost and having neat and attractive structural surfaces, and a water-stopping earth-retainingsupport protecting structural system of the combined type lattice form prefabricated pile wall support protecting structure and the construction method thereof is suitable for soft soil foundation foundation-pit projects and road slope and wharf revetment support protecting projects.
本发明公开了一种组合式格构形预制桩墙支护结构，包括有前排桩墙、后排桩墙、中间桩墙、平台板和扶壁挡墙；前排桩墙和后排桩墙为前后两排平行的密排预制预应力砼空心方桩，中间桩墙为数排垂直位于前排桩墙和后排桩墙之间的密排预制预应力砼空心方桩；预制预应力砼空心方桩的空腔内设现浇的钢筋砼填芯。据此，发明人还建立相应施工方法。本发明解决了预制支护桩应用在深基坑高边坡中刚度和承载力不足缺点，为无撑无锚要求的基坑支护提供了一种可快速施工的新的解决方案，具有省工期、省成本、结构表面整齐美观特点。本发明的止水挡土支护结构体系适合软土地基基坑工程、路崭边坡和码头护岸支护工程。
