Low-clearance full-casing cast-in-situ bored pile construction method
The invention discloses a construction method for a low-clearance full-pile-casing cast-in-situ bored pile. The construction method comprises the following steps that S1, paying-off positioning is conducted; s2, drilling by a drilling machine; s3, a protective cylinder is arranged below the vibratory hammer; s4, mounting a reinforcement cage; s5, concrete is poured; and S6, the pile casing is pulled out through the vibratory hammer. According to the construction method, bentonite or chemical slurry wall protection is not adopted in the construction of the full-pile-casing cast-in-situ bored pile, pollution to underground water is avoided, the construction site is clean and tidy, normal work and life of surrounding residents and enterprises are not affected, and the high environmental protection requirement is met; under the condition that a hole cannot be formed in a traditional cast-in-situ bored pile due to stratum and environmental protection reasons, it is guaranteed that pile foundation engineering construction is conducted smoothly; slurry does not need to be configured, the influence of wall protection mud cakes on the bearing capacity is avoided, the bearing capacity is reliable, and the pile body quality meets the standard requirement; the construction efficiency is high, and a good foundation is laid for smooth construction of the whole project.
本发明公开了一种低净空全护筒钻孔灌注桩施工方法，包括以下步骤：S1：放线定位；S2：钻机钻孔；S3：振动锤下护筒；S4：安装钢筋笼；S5：灌注混凝土；S6：振动锤拔出护筒。本发明，全护筒钻孔灌注桩施工不采用膨润土或化学泥浆护壁，对地下水没有污染，施工现场整洁，不影响周围居民及企业的正常工作和生活，满足高环保要求；在传统钻孔灌注桩因地层、环保原因无法成孔的情况下，保证桩基工程施工的顺利进行；不需要配置泥浆，没有护壁泥皮对承载力的影响，承载力可靠，桩体质量满足规范要求；施工效率高，为整体工程的顺利施工打下良好的基础。
