在拱形護坡施工時，應注意以下幾點：

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

　　沉降縫設置 ：護坡每隔15m~20m設置一道沉降縫，縫內采用瀝青棉絮或瀝青木板條填塞，縫寬2cm。這有助于防止因混凝土收縮而產生的裂縫。

　　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.

　　基面處理 ：對干燥的挖方槽底要適當灑水潤濕，以防混凝土水分過多流失，造成混凝土開裂。同時，對拱形梁與豎梁的接觸面要做鑿毛或拉毛處理，并用清水清洗干凈，以便混凝土的良好結合。

　　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.

　　模板安裝 ：模板安裝前，先安裝鋼管架的穩固架，并確保模板表面光潔、平整，接縫緊密，板體順直。模板安裝過程中要保證整體線型的直順性和總體坡面的圓順性。模板脫模劑必須涂抹均勻，嚴禁使用廢棄的機用油。模板拆除時，要按照混凝土的澆筑順序逐級拆除，拆除后的模板要集中放置，并對模板面板進行清理。

　　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.

　　混凝土澆筑 ：混凝土澆筑順序為：由底級到上級，先腳墻后豎梁再平臺，最后進行拱形架施工。混凝土的澆筑運輸采用車載+滑槽形式。在混凝土攪拌過程中嚴格控制混凝土的和易性及坍落度。澆筑時，嚴格控制振搗質量，確保混凝土停止下沉，不再冒出氣泡，表面呈現平坦、泛漿現象。澆筑后的混凝土要根據實際天氣情況，做好必要的灑水養生工作。

　　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.

　　現場管理 ：施工現場應設置專門的環保負責人，責任落實到人。施工現場要整齊、清潔，施工廢棄料集中堆放。注重施工現場的水土保持，盡量少占農田、耕地，保證原有水系的流通。施工中做到不影響農田正常灌溉和耕作。盡量少損壞林地，工程結束恢復原貌。

　　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 ：施工前進行詳細的勘察工作，包括地勢、地質條件等，并對設計方案進行認真審查。在基礎工程建設中，必須采用可靠的施工方法和先進的施工技術，確保其穩定性、安全性和質量。在骨架結構的安裝過程中，必須嚴格按照設計要求進行操作，并進行全程監督和管理。對現場責任人和工作人員進行安全教育和指導，減少工作人員的安全事故。定期檢查和維護拱形骨架護坡，尤其是在極端天氣條件下。使用拱形骨架護坡時，準備好應急預案，發生事故時能夠快速、有效、安全地處理。

　　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 ：現場管理有序，場地布置統一規劃。開展文明施工，減少對周邊環境的影響。

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