1、 Disclosure and setting out

主要是由項目經(jīng)理要對工人進(jìn)行技術(shù)交底，然后再是工人師傅根據設計要求放線(xiàn)，一般來(lái)說(shuō)開(kāi)槽寬度50mm。放線(xiàn)應當精準到位，無(wú)缺漏情況。

The project manager shall make technical disclosure to the workers, and then the worker's master shall set out according to the design requirements. Generally speaking, the slotting width is 50mm. The setting out shall be accurate and in place without omission.

二、舊物拆除

2、 Demolition of old objects

若有電線(xiàn)及開(kāi)關(guān)插座，那么接下來(lái)就是拆除原有電線(xiàn)及開(kāi)關(guān)插座。

If there are wires and switch sockets, the next step is to remove the original wires and switch sockets.

三、開(kāi)槽鉆孔

3、 Slotted drilling

依據施工現場(chǎng)實(shí)際的放線(xiàn)位置進(jìn)行開(kāi)槽，開(kāi)槽時(shí)必須注意開(kāi)槽深度。過(guò)墻和過(guò)梁的地方需要鉆孔，鉆孔時(shí)的孔徑、孔距一般為100mm；電線(xiàn)和水管不能走一個(gè)孔。

The slotting shall be carried out according to the actual setting out position on the construction site, and the slotting depth must be paid attention to during slotting. Where the wall and lintel pass through, drilling is required, and the hole diameter and hole spacing are generally 100mm; You can't go through a hole with a water pipe.

四、布管

4、 Pipe laying

根據在施工現場(chǎng)開(kāi)設的溝槽進(jìn)行布排管，在有水房間進(jìn)行布排管時(shí)電管應布設在墻上、頂上。強弱電線(xiàn)不允許走廚房、衛生間陽(yáng)臺的地面。

The pipes shall be arranged according to the grooves opened at the construction site. When the pipes are arranged in the room with water, the electric pipes shall be arranged on the wall and top. Strong and weak wires are not allowed to walk on the ground of kitchen, toilet and balcony.

在穿線(xiàn)時(shí)，一根電線(xiàn)管內所穿電線(xiàn)的截面積之和必須小于該管道內截面的40%。一般情況下16mm的電線(xiàn)不宜超過(guò)3根，20mm的電線(xiàn)不宜超過(guò)4根。

When threading, the sum of the cross-sectional areas of the wires in a wire pipe must be less than 40% of the cross-sectional area in the pipe. Generally, there should not be more than 3 16mm wires and 4 20mm wires.

五、檢查線(xiàn)路

5、 Check the circuit

運用萬(wàn)用表、歐姆表檢查線(xiàn)路暢通無(wú)阻，不出現短路以及斷路的現象，導線(xiàn)間絕緣電阻大于等于0.5mΩ，為安裝開(kāi)關(guān)插座作準備。

Use multimeter and ohmmeter to check that the line is unobstructed, there is no short circuit and open circuit, and the insulation resistance between conductors is greater than or equal to 0.5m Ω, so as to prepare for the installation of switch socket.

六、安裝開(kāi)關(guān)插座等

6、 Install switch socket, etc

在安裝之前不允許應用房屋內各插座，只能應用公司指定拖線(xiàn)盒。注意開(kāi)關(guān)插座面板應平整、緊貼建筑物表面。同一場(chǎng)所的開(kāi)關(guān)切斷位置一致，且操作靈活，接點(diǎn)接觸可靠。

Before installation, it is not allowed to use all sockets in the house, but only the cable box specified by the company. Note that the switch socket panel should be flat and close to the building surface. The cut-off positions of switches in the same place are the same, with flexible operation and reliable contact.
