12、時(shí)水引水管對(duì)線槽進(jìn)行澆水浸濕,使墻體充分濕潤(rùn)（若墻體濕潤(rùn),則不需要）。 The temporary water pipe of the floor must be used to water and soak the groove before fixing the electric box,make the wall fully moist (if the wall is wet, it is not necessary).152021/3/14 清理開(kāi)槽部位 clean dust and sand of the groove162021/3/14 濕潤(rùn)墻體 wet the wall 172

Cement mortar should be used to repair the groove. 232021/3/14 開(kāi)槽修補(bǔ) Groove fill242021/3/14三、質(zhì)量控制 Quality control 3.1箱盒面距粉刷面進(jìn)出控制不好原因分析:抹灰未按要求在

16、線盒固定前設(shè)置粉刷厚度控制基準(zhǔn)點(diǎn)（即灰餅）,因此箱盒固定時(shí)進(jìn)出控制無(wú)參照物,難以做到與后期粉刷面齊平。Reasons for poor control of inlet and outlet of the box surface from the painted surface:The painting team of the project department did not set the painting thickness control reference point (i.e., plaster sample) before the cable box was fixed acc

17、ording to the requirements. Therefore, there was no reference for the inlet and outlet control when the box was fixed, so it was difficult to be even with the later painting surface.252021/3/14 3.2預(yù)埋階段后砌墻上翻及下翻線管定位不準(zhǔn)確,工人施工比較隨意,未考慮后期線盒及電箱配管時(shí)線管排列需求。The positioning of the pre-burial stage is not correct

18、, and the workers are relatively arbitrary in construction, without considering the arrangement requirements of the later conduit and box.262021/3/14 3.3二次配管補(bǔ)槽后空鼓開(kāi)裂原因分析: 1.強(qiáng)弱電箱等線管多且密集處,開(kāi)槽寬度不足,線管之間無(wú)間距,開(kāi)槽深度不足,線管未進(jìn)行有效固定或固定點(diǎn)不足,補(bǔ)槽時(shí)砂漿無(wú)法與砌體墻有效粘接; 2.配管補(bǔ)槽前基層處理不到位,未清理附灰及灑水浸濕,水泥砂漿強(qiáng)度不夠,導(dǎo)致砂漿與線管及砌體粘接強(qiáng)度不足,水泥砂漿與砌體的

19、粘接力無(wú)法與收縮力相平衡,從而導(dǎo)致空鼓、開(kāi)裂與基層脫離現(xiàn)象; 3.補(bǔ)槽完成后未灑水養(yǎng)護(hù)。 1.The conduit and box is much and dense, groove wide is not enough, The depth of the groove is not enough, no effective tie, and the mortar cannot effectively bond with the wall when the groove is filled; 2.The cement mortar is not strong enough, resulting bonding strength not enough. 3.No water spraying maintenance after the filled of groove .272021/3/14 3.4:多個(gè)開(kāi)關(guān)插座并列在一塊時(shí),應(yīng)根據(jù)開(kāi)關(guān)插座大小確定線盒間距。 When multiple switch and sockets are fixed together, the electric box gap should be determined according to the size of the switch and socket.282021/3/14四
