1、水泥砂浆或混凝土基层，必须坚固、密实、平整；基层的坡度和强度应符合设计要求，不应有起砂、起壳、裂缝、峰窝麻面等现象。平整度应用2m直尺检查，允许空缝不应大于5mm。
1. The cement mortar or concrete base must be firm, dense and flat; the gradient and strength of the base shall meet the design requirements, and there shall be no sanding, shelling, cracks, pits and pits. The flatness shall be checked with a 2m ruler, and the allowable gap shall not be greater than 5mm.
2、当在水泥砂浆或混凝土基层表面进行块材铺砌施工时，基层的阴阳角应做成直角；进行其他种类防腐施工时，基层的阴阳角应做成斜面或圆角。
2. When the block paving construction is carried out on the surface of cement mortar or concrete base course, the internal and external corners of the base course shall be made into right angles; when other kinds of anti-corrosion construction is carried out, the internal and external corners of the base course shall be made into inclined surfaces or rounded corners.
3、 基层必须干燥。在深为20mm的厚度层内，含水率不应大于6%。当设计对湿度有特殊要求时，应按设计要求进行施工。
3. The base must be dry. The water content shall not be greater than 6% in the thickness layer with a depth of 20 mm. When the design has special requirements for humidity, the construction shall be carried out according to the design requirements.
4、 基层表面必须洁净。防腐蚀施工前，应将基层表面的浮水、水泥渣及疏松部位清理干净。基层表的处理方法。宜采用砂轮或钢丝刷等打磨，然后用干净的软毛刷、压缩空气或吸尘器清理干净。当有条件时，可采用轻度喷砂法，使基层形成均匀粗糙面。
4. The base surface must be clean. Before anti-corrosion construction, the floating water, cement slag and loose parts on the base surface shall be cleaned. Treatment method of base surface. Grinding wheel or wire brush should be used for grinding, and then clean with clean soft brush, compressed air or vacuum cleaner. When conditions permit, light sand blasting can be used to form a uniform rough surface of the base course.
5、 已被油脂、化学药品污染的表面或改建、扩建工程中已被侵蚀的疏松基层，应进行表面预处理，处理方法应符合下列规定：
5. The surface polluted by grease and chemicals or the eroded loose base course in reconstruction and expansion project shall be pretreated, and the treatment method shall meet the following requirements:
6、 被油脂、化学药品污染的表面，可使用溶剂、洗涤剂、碱液洗涤或用火烤、蒸汽吹洗等方法处理，但不得损坏基层；
6. The surface polluted by grease and chemicals can be washed with solvent, detergent and alkali solution or treated with fire baking and steam blowing, but the base course shall not be damaged;
7、 被腐蚀介质侵蚀的疏松基层，必须凿除干净，用细石混凝土等填补，养护之后按新的基层进行处理。
7. The loose base course eroded by corrosive medium must be chiseled clean, filled with fine aggregate concrete, etc., and treated as a new base course after maintenance.
8、封底层：在经过处理的基层表面，均匀地涂刷封底料，不得有漏涂，流挂等缺陷，自固化不宜少于24H。
8. Bottom sealing layer: on the surface of the treated base course, the bottom sealing material shall be brushed evenly, without defects such as missing coating and sagging, and the self curing time shall not be less than 24h.
9、修补层：在基层的凹陷不平处，应采用树脂胶泥料修补填平，自然固化不宜小于24H，用树脂胶泥料修刮平基层。
9. Repair layer: at the concave and uneven parts of the base course, the resin glue slurry shall be used for repair and filling, and the natural curing time shall not be less than 24h. The resin glue slurry shall be used for repair and scraping of the base course.
