　　在拱形护坡施工时，应注意以下几点：

　　When constructing arched slope protection, the following points should be noted:

　　沉降缝设置 ：护坡每隔15m~20m设置一道沉降缝，缝内采用沥青棉絮或沥青木板条填塞，缝宽2cm。这有助于防止因混凝土收缩而产生的裂缝。

　　Setting of settlement joint: a settlement joint shall be set every 15m~20m for slope protection, and the joint shall be filled with asphalt batten or asphalt batten, with a width of 2cm. This helps prevent cracks caused by concrete shrinkage.

　　基面处理 ：对干燥的挖方槽底要适当洒水润湿，以防混凝土水分过多流失，造成混凝土开裂。同时，对拱形梁与竖梁的接触面要做凿毛或拉毛处理，并用清水清洗干净，以便混凝土的良好结合。

　　Base treatment: The dry bottom of the excavation trench should be moistened with water appropriately to prevent excessive loss of concrete moisture and cracking. At the same time, the contact surface between the arched beam and the vertical beam should be chiseled or roughened, and cleaned with clean water to ensure good bonding of the concrete.

　　模板安装 ：模板安装前，先安装钢管架的稳固架，并确保模板表面光洁、平整，接缝紧密，板体顺直。模板安装过程中要保证整体线型的直顺性和总体坡面的圆顺性。模板脱模剂必须涂抹均匀，严禁使用废弃的机用油。模板拆除时，要按照混凝土的浇筑顺序逐级拆除，拆除后的模板要集中放置，并对模板面板进行清理。

　　Template installation: Before installing the template, first install the stable bracket of the steel pipe frame, and ensure that the surface of the template is smooth, flat, the joints are tight, and the plate body is straight. During the template installation process, it is necessary to ensure the straightness of the overall line shape and the roundness of the overall slope surface. The template release agent must be applied evenly, and the use of waste machine oil is strictly prohibited. When dismantling the formwork, it should be dismantled step by step according to the pouring order of the concrete. The dismantled formwork should be placed in a centralized manner and the formwork panels should be cleaned.

　　混凝土浇筑 ：混凝土浇筑顺序为：由底级到上级，先脚墙后竖梁再平台，最后进行拱形架施工。混凝土的浇筑运输采用车载+滑槽形式。在混凝土搅拌过程中严格控制混凝土的和易性及坍落度。浇筑时，严格控制振捣质量，确保混凝土停止下沉，不再冒出气泡，表面呈现平坦、泛浆现象。浇筑后的混凝土要根据实际天气情况，做好必要的洒水养生工作。

　　Concrete pouring: The sequence of concrete pouring is from the bottom to the top, starting with the foot wall, then the vertical beam, and finally the platform, and finally the arch frame construction. The pouring and transportation of concrete adopts the form of vehicle mounted and chute. Strictly control the workability and slump of concrete during the mixing process. During pouring, strictly control the vibration quality to ensure that the concrete stops sinking, no more bubbles appear, and the surface presents a flat and bleeding phenomenon. The poured concrete should be properly watered and cured according to the actual weather conditions.

　　现场管理 ：施工现场应设置专门的环保负责人，责任落实到人。施工现场要整齐、清洁，施工废弃料集中堆放。注重施工现场的水土保持，尽量少占农田、耕地，保证原有水系的流通。施工中做到不影响农田正常灌溉和耕作。尽量少损坏林地，工程结束恢复原貌。

　　On site management: A dedicated environmental protection officer should be appointed at the construction site, and responsibilities should be assigned to individuals. The construction site should be neat and clean, and construction waste materials should be centrally stacked. Pay attention to soil and water conservation at the construction site, minimize the occupation of farmland and arable land, and ensure the circulation of the original water system. Ensure that the construction does not affect the normal irrigation and cultivation of farmland. Minimize damage to forest land and restore the original appearance after the project is completed.

　　安全措施 ：施工前进行详细的勘察工作，包括地势、地质条件等，并对设计方案进行认真审查。在基础工程建设中，必须采用可靠的施工方法和先进的施工技术，确保其稳定性、安全性和质量。在骨架结构的安装过程中，必须严格按照设计要求进行操作，并进行全程监督和管理。对现场责任人和工作人员进行安全教育和指导，减少工作人员的安全事故。定期检查和维护拱形骨架护坡，尤其是在极端天气条件下。使用拱形骨架护坡时，准备好应急预案，发生事故时能够快速、有效、安全地处理。

　　Safety measures: Conduct detailed survey work before construction, including terrain, geological conditions, etc., and carefully review the design plan. In basic engineering construction, reliable construction methods and advanced construction techniques must be adopted to ensure its stability, safety, and quality. During the installation process of the skeleton structure, it is necessary to strictly follow the design requirements and conduct full supervision and management throughout the process. Provide safety education and guidance to on-site responsible personnel and staff to reduce safety accidents among staff. Regularly inspect and maintain arch skeleton slope protection, especially under extreme weather conditions. When using arched skeleton slope protection, prepare emergency plans to quickly, effectively, and safely handle accidents.

　　文明施工 ：现场管理有序，场地布置统一规划。开展文明施工，减少对周边环境的影响。

　　Civilized construction: orderly on-site management and unified planning of site layout. Carry out civilized construction to reduce the impact on the surrounding environment.
