实践证明,土坝坝体灌注泥浆解决防渗和稳定问题,效果好,投资少,施工简单,是土坝除险加固的重要措施。在灌浆施工过程中,会经常遇到一些技术性的问题。如:坝体裂缝、冒浆、串浆、塌坑、隆起、单孔吃浆量大以及弧形坝产生切线劈裂等。本文综述了这些问题产生的原因,控制措施以及处理办法等方面的经验,供灌浆施工单位参考。一、裂缝土坝坝体灌浆期坝面常出现裂缝,按裂缝的走向可分为纵向缝和横向缝。其产生的原因
Practice has proved that earth dam dam perfusion slurry to solve the seepage and stability problems, the effect is good, less investment, construction is simple, is an important measure for earth dam reinforcement. During the grouting construction, we often encounter some technical problems. Such as: dam body, mud, string pulp, collapse pit, uplift, single-hole to eat a large amount of slurry and arc dam tangential cleavage. This paper summarizes the causes of these problems, control measures and treatment methods and other aspects of experience for the grouting construction unit for reference. First, cracks Earth dam dam filling often appear cracks in the dam surface, according to the trend of cracks can be divided into longitudinal and transverse cracks. The reason for its production
