Non-pressure diversion tunnel formwork erecting and concrete spraying lining and construction method
The invention discloses a non-pressure diversion tunnel formwork erecting and concrete spraying lining and a construction method. The construction method is characterized by comprising the following steps that S1, a primary support section is checked and measured; S2, bottom plate concrete lining is carried out; S3, side wall formwork erecting and concrete spraying construction is carried out; S4, top arch concrete spraying construction is carried out; and S5, concrete spraying, form removal and maintenance are carried out. The construction method has the beneficial effects that the construction progress is accelerated, compared with traditional secondary lining concrete construction, the construction time of the edge top arch of each bin in formwork erecting and concrete spraying construction is shortened by about 10 hours and nearly half, and the construction efficiency is remarkably improved; through application of the construction method, engineering construction can be accelerated, and the engineering project investment is reduced; and the construction method is simple and convenient in operation technology and is easy for grasping by working personnel, the construction equipment is less, the occupied space is small, the maintenance is easy, the operation is more flexible, various surrounding rock foundations can be adapted, the construction organization and scheduling are relatively simple, and the operation teams are pleasant to accept.
本发明公开了一种无压引水隧洞立模喷砼内衬及施工工法，其特征在于：包括以下步骤：S1，初期支护断面检查测量；S2、底板混凝土衬砌；S3、边墙立模喷砼施工；S4、顶拱喷砼施工；S5、喷砼拆模与养护。本发明的有益效果在于：加快施工进度，与传统二衬混凝土施工相比，立模喷砼施工每仓边顶拱施工时间减少约10h，缩短近一半的时间，显著地提高施工效率了，通过工法的应用，可加快完成工程建设，减少工程项目投资，且此工法操作技术简便，易于作业人员掌握，施工设备较少，占用空间小，易于维护，更机动灵活，能适应各类围岩基础，施工组织与调度相对简单，作业班组乐于接受。
