1.. Rubber sealing strip is made of natural rubber and various synthetic rubber as the main raw material, and the filling material mixed with various additives, through mixing, mixing, molding, the more varieties of different specifications, bridge, mountain type, P type, R type, U type, Z type, T type, H type, type B E type and Q type, etc.. The sealing material has good elasticity, wear resistance, aging resistance and tear resistance. It has strong deformation capacity and waterproof performance, and its temperature range is -45 -+60 C. The product should not be used when the temperature is more than +70 C, as well as the strong oxidation or the corrosion of organic solvents, such as oil.
2.主要設(shè)置在分部施工縫處,以增加兩次混凝土施工結(jié)合面積,主要來滿足施工縫防水要求,應(yīng)按其厚度分別采用折疊咬接或搭接；
The 2. is mainly located in the construction joints of the sub section, so as to increase the two times of the concrete construction joint area, mainly to meet the waterproof requirements of the construction joints.
3.止水帶鋼板型號(hào)是寬300mm,厚3mm的鋼板,長度3m1塊,材質(zhì)為Q235鋼。施工時(shí)用對(duì)拉螺栓做水平支撐架,確保止水帶的垂直度及高程滿足設(shè)計(jì)及規(guī)范要求;混凝土澆筑完畢后要及時(shí)清理止水鋼板上部被混凝土污染部分,防止上部混凝土澆筑時(shí)與鋼板結(jié)合不良;下部施工完畢后,盡早鑿毛清理,確保上部施工時(shí)混凝土能良好的結(jié)合;澆筑上部混凝土前,應(yīng)用高壓或水槍沖洗底部混凝土,清除上部結(jié)構(gòu)施工時(shí)散落的灰渣等污染物,在澆筑上部結(jié)構(gòu)混凝土?xí)r,首層應(yīng)該先澆筑2cm左右厚度的同等標(biāo)號(hào)砂漿,一方面潤濕先期施工的混凝土表層,起到良好的結(jié)合層的作用,另一方面來檢查模板支護(hù)情況,確保構(gòu)筑物外觀尺寸符合設(shè)計(jì)及規(guī)范要求。設(shè)置鋼板止水帶在一定程度上解決了因?yàn)槭┕すに囁较拗?留置施工縫而發(fā)生滲漏的問題。
3. water stop strip plate model is wide 300mm, thick 3mm steel plate, length 3M1 block, material is Q235 steel. With the bolt horizontal supporting frame construction, ensure the verticality and elevation of strip to meet the design requirements and specifications; after the concrete pouring to clean up the upper sealing plate is part of the pollution of concrete, concrete pouring and prevent the upper plate and lower side; after the construction as soon as possible, cut hair clean, ensure the concrete construction can be a good combination; the upper concrete pouring, using high pressure water gun flushing or bottom concrete, scattered clear upper structure construction when the ash and other pollutants in the upper part of the structure of concrete pouring, the first layer should be equally labeled first mortar pouring 2cm about the thickness of the concrete surface, a pre wetting construction, play a good combination of layers the role, on the other hand to check the template support, ensure the structure appearance size meet the design requirements and norms. To a certain extent, the installation of steel plate has solved the problem that the construction seams must be leaked because of the limit of the construction technology.
4.這種方法也有三方面的不足之處:①由于使用大量的鋼板及支撐構(gòu)件造,不經(jīng)濟(jì);②施工工藝較復(fù)雜,需分段焊接止水鋼板、支撐結(jié)構(gòu),在構(gòu)筑物鋼筋結(jié)構(gòu)復(fù)雜時(shí)安裝鋼板較困難,下部結(jié)構(gòu)施工完畢后,要清理被污染的鋼板;③防滲效果不理想,下部結(jié)構(gòu)澆筑混凝土?xí)r經(jīng)常碰撞鋼板,導(dǎo)致其變形移位,混凝土澆筑高程也難以控制,上部結(jié)構(gòu)澆筑混凝土?xí)r振搗困難,經(jīng)常因?yàn)槁┱癜粗圃觳馁|(zhì)分為： 橡膠止水帶（R），如：天然膠、氯丁膠、丁苯膠等
This method has 4. shortcomings in three aspects: 1. Due to extensive use of steel plate and a supporting component of high cost, not the economy; the construction process is relatively complex, need welding sealing plate, supporting structure, the installation plate is difficult in building steel structure is complex, the lower part of the structure after completion of construction, to clean the polluted the steel plate; the anti-seepage effect is not ideal, the lower part of the structure of pouring concrete often leads to the deformation of plate collision, displacement, concrete pouring height is also difficult to control, the upper structure of pouring concrete vibration is difficult, often because of the leakage of vibration in manufacturing rubber waterstop material is divided into: (R), such as: natural rubber, chloroprene rubber styrene butadiene rubber, etc.
塑料止水帶（P），如：聚氯乙烯、聚乙烯等
Plastic water stop (P), such as PVC, PE, etc.
金屬止水帶（M），如：銅、不銹鋼、碳鋼等
Metal water stop (M), such as copper, stainless steel, carbon steel, etc.
