2. Installation method of buried parts

2.1 测量放线，控制闸门轴线、高程及基底水平线、位置。 

2.1 measure the discharge line, control the gate axis, elevation and base horizontal line and position.  

2.2 预埋在一起混凝土中的锚栓或锚板，应按设计图样制造，有土建施工单位预埋位置进行检查核对。 

2.2 Anchor bolts or anchor plates embedded in concrete shall be manufactured according to the design drawings and checked by the pre-embedded position of the civil construction unit.  

2.3   埋件安装前门槽中的模板杂物必须清除干净。混凝土的结合面应全部凿毛，检查验收凿槽深度、宽度尺寸、检查二期混凝土的断面尺寸是否符合施工及预埋件安装图样要求。 

2.3 template material must be removed before installation. The joint surface of the concrete should be chiseled completely to check the depth and width of the chiseling groove for acceptance and to check whether the sectional dimension of the second stage concrete meets the requirements of the construction and the installation drawings of the embedded parts.  

2.4   平面闸门埋件安装允许公差与偏差必须符合DL/T5018-2004《水利水电工程钢闸门制造、安装及验收规范》中的预留锚栓、锚筋或一期预埋连接焊牢。加固钢筋的直径不小于锚栓的直径，其两端与埋件及锚栓的焊接长度均不应小于50mm。确保埋件在浇筑二期混凝土过程中不发生变形或者们位移。若对埋件的加固另有要求时，应按设计图样要求予以加固，严禁将加固材料直接焊接在主轨、反轨、底槛等的工作面上或水封座板上。 

2.4 The allowable tolerances and deviations for the installation of embedded parts of plane gates must conform to the pre-reserved anchor bolts, anchor bars or pre-embedded connection soldered in DL/T5018-2004 "Specifications for Manufacturing, Installation and Acceptance of Steel Gates for Water Conservancy and Hydropower Projects". The diameter of the reinforced bar is not less than the diameter of the anchor bolt, and the welding length between the two ends and the embedded parts and the anchor bolt should not be less than 50 mm. Ensure that the embedded parts do not deform or displace during the two stage concrete placement. If there are other requirements for the reinforcement of the embedded parts, they should be reinforced according to the design drawings. It is strictly forbidden to weld the reinforcement materials directly to the working face of the main rail, anti-rail, bottom sill, or water seal plate.  

2.6   埋件上所有不锈钢材料的焊接接头，必须使用相应的不锈钢焊条进行焊接。 

2.6 All stainless steel welded joints on buried parts must be welded with corresponding stainless steel electrode.  

2.7   埋件安装经检查合格，要按设计图纸要求及配比，控制好砼混凝土的现浇工序及工艺。处理好浇筑后的混凝土表面及下道工序在5~7d内浇筑二期混凝土。混凝土一次洚筑不宜超过5.0m，在浇筑过程中应防止撞击，并应采取措施捣实混凝土。 

2.7 Installation of buried parts after inspection qualified, according to the design drawings and mix requirements, to control the cast-in-place concrete process and technology. The two stage concrete will be poured in the 5~7d after the concrete surface and the next working procedure are disposed well. The concrete should not exceed 5.0m in one pouring. The impact should be prevented during pouring and measures should be taken to tamp the concrete.  

2.8   闸门埋件的安装要符合技术及规范要求，采用全站仪或水平仪、垂球、拉钢丝线等检查测量，埋件二期混凝土拆模后，应对埋件进行复测，作好记录，并检查混凝土面尺寸，清除遗留的钢筋和杂物。对所有的工作面进行清理，门槽范围内，影响闸门安全运行的外露物必须清除干净。 

2.8 Installation of embedded parts of sluice gates should conform to technical and normative requirements. Total station or level instrument, vertical ball, steel wire and other inspection and measurement should be used. After demolition of the second stage concrete of embedded parts, the embedded parts should be re-tested, recorded, and the size of concrete surface checked to remove the remaining reinforcement and debris. Clean up all working faces, within the scope of the door slot, the exposed matter affecting the safe operation of the gate must be removed.  

2.9   埋件工作表面对接头的错位进行缓坡处理。工作面的焊疤、焊缝、余高以及凹坑应铲平、焊平和磨光埋件所有工作面上的连接焊缝，在安装工作完毕和浇筑二期混凝土后，仔细打磨，其表面粗糙应与焊妆构件一致。 

2.9 the working surface of the buried part is treated with gentle slope for the dislocation of the joint. The welding scar, weld seam, residual height and pit of the working face should be leveled, welded and polished. After installation and placement of the second stage concrete, the surface roughness should be the same as the weld makeup component.  

2.10   安装好的门槽。除了主轨导轨面、水封座的不锈钢表面外，其余外露表面，进行防腐处理。 

2.10 installed door slot. Besides the surface of the main rail and the stainless steel surface of the water seal seat, the other exposed surfaces are treated with corrosion protection.  

2.11   工程挡水前应进行试槽。

2.11 the test tank should be tested before water blocking.
