        檢查井五種施工工法有如下優缺點:
        檢查井五種施工工法有如下優缺點:
        Five construction methods of inspection wells have the following advantages and disadvantages:
        1、傳統磚砌檢查井:需要人工砌筑,質量取決于工人技術水平。勞動生產率低下,不利于管道裝配化快速施工,影響城市交通。強度低、使用一段時間后表皮脫落內里疏松,造成檢查井整體下沉,周邊路面沉降,成為道路工程中的一大通病。透水性高,污染地下水資源。粘土燒結,破壞耕地。
        1. Traditional brick inspection wells: need to be manually built, the quality depends on the technical level of workers. Low labor productivity is not conducive to rapid pipeline assembly construction, affecting urban traffic. Low strength and loose inner skin after using for a period of time cause the overall subsidence of inspection wells and the settlement of surrounding pavement, which has become a common problem in road engineering. High permeability and pollution of groundwater resources. Clay sintering destroys farmland.
        2、現澆混凝土檢查井:現場模板支護,開挖斷面大,擾動現狀土范圍大。異型檢查井支護模板難度大。養護時間長??傮w造價高。
        2. Cast-in-situ concrete inspection wells: on-site formwork support, large excavation section, large disturbance current soil range. The support formwork of special-shaped inspection wells is very difficult. Maintenance time is long. The overall cost is high.
        3、預制裝配和模塊砌筑檢查井:預制裝配式鋼筋砼檢查井的大型預制件在城市中運輸難度大(立交橋、過街天橋限高)。施工現場需要吊車,增加造價。接入管高程、管徑大小與方向控制精度要求高。需要模具數量較大。預制混凝土模塊檢查井已形成標準化、系列化,總體造價較預制裝配式鋼筋砼檢查井低,但強度與施工稍遜。目前注漿和防滲有待研究。
        3. Prefabricated assembly and modular masonry inspection wells: Large prefabricated parts of prefabricated reinforced concrete inspection wells are difficult to transport in cities (overpasses and overpasses are limited to high levels). The construction site needs cranes to increase the cost. The control accuracy of height, diameter and direction of access pipe is required. A large number of moulds are needed. The prefabricated concrete module inspection wells have been standardized and serialized. The overall cost of prefabricated reinforced concrete inspection wells is lower than that of prefabricated prefabricated reinforced concrete inspection wells, but the strength and construction are slightly lower. At present, grouting and seepage prevention need to be studied.
        4、需制作沉井、施工速度慢、接入管高程、方向和均勻垂直沉降與難于控制。
        4. The caisson needs to be made, the construction speed is slow, the elevation, direction and even vertical settlement of the access pipe are difficult to control.
        5、塑料檢查井:強度低、不能上重型碾壓機具、與不同材質管材連接有難度、井室小于1200、井周難于回填密室。豎向承載能力低,用于道路需要對井口進行復雜處理。
        5. Plastic inspection wells: low strength, unable to use heavy rolling tools, difficult to connect with different materials, wellbore less than 1200, wellbore is difficult to backfill. Vertical bearing capacity is low, so it needs complex treatment of wellhead for road.
