Cement mixing pile enclosure wall-section steel cantilever type combined support
The invention discloses a cement mixing pile enclosure wall-section steel cantilever type combined support. Section steel is inserted into the outer side and the inner side of a cement mixing pile enclosure wall respectively to form the combined support, the compression resistance and the anti-pressure ability of an enclosure structure are enhanced through the section steel, and therefore, deformation of the enclosure structure is reduced. A reinforced concrete crown beam and a rigid frame plate are arranged on the top of the combined support, a portal rigid frame structure is formed by the reinforced concrete crown beam, the rigid frame plate and the section steel on the inner side and the outer side, and the rigidity and the integrity of the enclosure structure are improved. Steel bars are inserted into the cement mixing pile enclosure wall, and the rigidity of a cement soil wall is improved. The bottom of a foundation pit is reinforced so that the anti-overturning and anti-uplift stability of the enclosure structure is improved. The cement mixing pile enclosure wall-section steel cantilever type combined support can be used for the situation that the construction condition of the enclosure structure is limited or a structure (building) needing to be protected exists outside the pit, the rigidity of the enclosure structure can be effectively improved under the condition thatthe width of the enclosure structure is not increased, lateral deformation of the enclosure structure and surface settlement outside the pit are reduced, the influence on the surrounding environment from foundation pit excavation is reduced, the engineering construction period is shortened, and good practicability and social benefits are achieved.
本发明公开了一种水泥土搅拌桩围护墙‑型钢悬臂式组合支护，水泥土搅拌桩围护墙外侧和内侧分别插入型钢形成组合支护，由型钢加强围护结构的抗压和抗压能力，从而减小围护结构变形；组合支护顶设置钢筋混凝土冠梁和刚架板，与内外侧型钢形成门式刚架结构，增加围护结构刚度和整体性；水泥土搅拌桩围护墙内插入钢筋，增大水泥土墙刚度；基坑底施工坑底加固增加围护结构抗倾覆和抗隆起稳定性。本发明可用于围护结构施工条件受限或坑外有需保护构（建）筑物的情况，可在不增大围护结构宽度的条件下有效增大围护结构刚度，减少围护结构的侧向变形及坑外地表沉降，降低对基坑开挖对周边环境的影响，减少工程施工周期，具有良好的实用性和社会效益。
