　　在拱形護(hù)坡施工時(shí)，應(yīng)注意以下幾點(diǎn)：

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

　　沉降縫設(shè)置 ：護(hù)坡每隔15m~20m設(shè)置一道沉降縫，縫內(nèi)采用瀝青棉絮或?yàn)r青木板條填塞，縫寬2cm。這有助于防止因混凝土收縮而產(chǎn)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(duì)干燥的挖方槽底要適當(dāng)灑水潤(rùn)濕，以防混凝土水分過(guò)多流失，造成混凝土開裂。同時(shí)，對(duì)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(jié)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(wěn)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(guò)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(yán)禁使用廢棄的機(jī)用油。模板拆除時(shí)，要按照混凝土的澆筑順序逐級(jí)拆除，拆除后的模板要集中放置，并對(duì)模板面板進(jìn)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?yàn)椋河傻准?jí)到上級(jí)，先腳墻后豎梁再平臺(tái)，最后進(jìn)行拱形架施工?；炷恋臐仓\(yùn)輸采用車載+滑槽形式。在混凝土攪拌過(guò)程中嚴(yán)格控制混凝土的和易性及坍落度。澆筑時(shí)，嚴(yán)格控制振搗質(zhì)量，確?；炷镣Ｖ瓜鲁粒辉倜俺鰵馀?，表面呈現(xiàn)平坦、泛漿現(xiàn)象。澆筑后的混凝土要根據(jù)實(shí)際天氣情況，做好必要的灑水養(yǎng)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(xiàn)場(chǎng)管理 ：施工現(xiàn)場(chǎng)應(yīng)設(shè)置專門的環(huán)保負(fù)責(zé)人，責(zé)任落實(shí)到人。施工現(xiàn)場(chǎng)要整齊、清潔，施工廢棄料集中堆放。注重施工現(xiàn)場(chǎng)的水土保持，盡量少占農(nóng)田、耕地，保證原有水系的流通。施工中做到不影響農(nóng)田正常灌溉和耕作。盡量少損壞林地，工程結(jié)束恢復(fù)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(jìn)行詳細(xì)的勘察工作，包括地勢(shì)、地質(zhì)條件等，并對(duì)設(shè)計(jì)方案進(jìn)行認(rèn)真審查。在基礎(chǔ)工程建設(shè)中，必須采用可靠的施工方法和先進(jìn)的施工技術(shù)，確保其穩(wěn)定性、安全性和質(zhì)量。在骨架結(jié)構(gòu)的安裝過(guò)程中，必須嚴(yán)格按照設(shè)計(jì)要求進(jìn)行操作，并進(jìn)行全程監(jiān)督和管理。對(duì)現(xiàn)場(chǎng)責(zé)任人和工作人員進(jìn)行安全教育和指導(dǎo)，減少工作人員的安全事故。定期檢查和維護(hù)拱形骨架護(hù)坡，尤其是在極端天氣條件下。使用拱形骨架護(hù)坡時(shí)，準(zhǔn)備好應(yīng)急預(yù)案，發(fā)生事故時(shí)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(xiàn)場(chǎng)管理有序，場(chǎng)地布置統(tǒng)一規(guī)劃。開展文明施工，減少對(duì)周邊環(huán)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.
