Anchor rod lattice slope protection construction method based on tunnel underground excavation section permanent heading slope
The invention provides an anchor rod lattice slope protection construction method based on a tunnel underground excavation section permanent heading slope. The anchor rod lattice slope protection construction method comprises the following steps of S1, surveying and setting out, specifically, anchor rod construction is completed, the slope ratio and the like of an excavated slope body are manuallyfinished and meet requirements, and then the position of a lattice beam and the construction initial range are surveyed; S2, slope surface grooving, specifically, a groove is excavated manually according to the position and size of the lattice beam measured by a measurer, the groove is excavated by 20 cm outside structural lines of the two sides of the lattice beam, and a formwork and a supporting structure can be installed conveniently; S3, reinforcing steel bars machining and binding; S4, formwork installing, specifically, bamboo plywood with the thickness of 15 mm is adopted as the formwork to be spliced according to the design size, square timber with the length of 5 * 10 cm is adopted as straps, and the surface of the formwork is cleared up and brushed with a release agent; and S5, concrete pouring. According to the anchor rod lattice slope protection construction method, the anchor rod lattice is arranged stably, casting bodies are not prone to deformation, all structures of theanchor rod lattice can be stressed evenly, and the slope maintenance stability is good.
本发明提供了一种基于隧道暗挖段永久边仰坡的锚杆格构护坡施工方法，包括如下步骤：S1、测量放样：锚杆施做完成，开挖坡体在人工修整其坡比等达到要求，然后测放出格构梁位置及施作起始范围；S2、坡面刻槽：根据测量人员测放出的格构梁位置和尺寸人工开挖沟槽，沟槽在格构梁两侧结构线外各扩挖20cm，便于安装模板和支撑结构；S3、钢筋加工与绑扎：S4、模板安装：模板采用15mm厚的竹胶板按设计尺寸进行拼装，背带采用5×10cm方木，模板表面清理干净并刷脱模剂；S5、混凝土浇筑。本发明的该施工方法的锚杆格构设置稳定，浇注体不易变形，能够使锚杆格构各个结构受力均匀，坡体维护的稳定性好。
