Enclosure system with H-shaped sheet piles combined with umbrella-shaped structure by supporting first and then digging and construction method of enclosure system
The invention relates to an enclosure system of a firstly-supported and secondly-excavated H-shaped sheet pile combined umbrella-shaped structure and a construction method of the enclosure system. The enclosure system comprises a coping ring beam, vertical H-shaped sheet piles and inner and outer inclined piles. According to the enclosure system, inclined piles inside and outside a pit and vertical H-shaped sheet piles are connected through ring beams to form an umbrella-shaped self-stabilizing system, the inclined piles inside and outside the pit and the vertical H-shaped sheet piles are inserted into a soil layer at the angle of 10-45 degrees, the vertical H-shaped sheet piles are constructed through cement mixing piles firstly, then the H-shaped sheet piles are embedded into the cement mixing piles to be combined with the cement mixing piles to form a supporting wall with the soil retaining and water stopping performance, and the cement mixing piles and the H-shaped sheet piles are combined. And the inclined piles inside and outside the pit, the tops of the H-shaped sheet piles and the ring beam are cast-in-place and connected into a whole. The supporting structure has the advantages that compared with the prior art, the supporting structure does not need a horizontal inner support, the manufacturing cost is saved, meanwhile, earth excavation is convenient and faster, the working procedure of firstly supporting and then excavating is adopted, the construction period is shortened, the working efficiency is improved, a specific umbrella-shaped self-stabilizing structure system is adopted, the structure is more stable, and the deformation resistance is remarkably improved.
本发明涉及一种先撑后挖H板桩结合伞形结构的围护体系及其施工方法，所述围护体系包括压顶圈梁、竖向H板桩、内外斜向桩；所述的围护体系由坑内外斜向桩与竖向H板桩通过圈梁连接形成伞型自稳体系，所述坑内外斜向桩与竖向H板桩以10°～45°插入土层中，所述竖向H板桩通过水泥搅拌桩先施工，后植入H板桩与搅拌桩结合形成具有挡土止水性能的支护墙，所述坑内外斜向桩与H板桩顶部跟圈梁现浇连接成整体。本发明的优点是：与现有技术相比，本支护结构无需水平内支撑，节约造价，同时土方开挖方便更快捷，采用先撑后挖工序，节约工期，提高了工作效率，特有的伞型自稳结构体系，结构更稳定，抵抗变形能力显著提高。
