所謂的溝槽邊緣的裂縫，主要就是針對(duì)家里在水電改造的時(shí)候，墻面上所開的溝槽接縫。在溝槽內(nèi)布置水管線管之后，一般都是使用相應(yīng)的材料對(duì)溝槽進(jìn)行恢復(fù)，在恢復(fù)過(guò)程中沒(méi)有處理好就可能出現(xiàn)裂縫。常見原因如下：

　　The so-called cracks at the edge of the groove are mainly aimed at the joints of the grooves opened on the wall during the water and electricity renovation at home. After arranging water pipes in the trench, corresponding materials are usually used to restore the trench. If not properly treated during the restoration process, cracks may occur. The common reasons are as follows:

　　原因分析

　　Cause analysis

　　①回填溝槽的時(shí)候，溝槽內(nèi)回填材料不密實(shí)。使用回填材料來(lái)回填溝槽的時(shí)候沒(méi)有將內(nèi)部填塞密實(shí)，例如管道底部虛空的，就容易造成溝槽的開裂。

　　① When backfilling the trench, the backfill material inside the trench is not dense enough. When using backfill materials to fill the trench back and forth, if the interior is not filled tightly, such as the void at the bottom of the pipeline, it is easy to cause the trench to crack.

　　②溝槽回填材料選擇不正確。對(duì)于水電的溝槽，個(gè)人認(rèn)為應(yīng)該是高強(qiáng)的水泥砂漿或者是細(xì)石混凝土回填，不允許使用粉刷石膏回填。

　　② The selection of backfill material for the trench is incorrect. For water and electricity trenches, I personally believe that high-strength cement mortar or fine aggregate concrete should be used for backfilling, and the use of plaster for backfilling is not allowed.

　　③回填以后，沒(méi)有對(duì)溝槽的回填材料進(jìn)行養(yǎng)護(hù)。例如使用水泥砂漿回填溝槽，沒(méi)有及時(shí)的灑水養(yǎng)護(hù)，導(dǎo)致水泥砂漿失水而出現(xiàn)了開裂。

　　③ After backfilling, the backfill material for the trench was not cured. For example, using cement mortar to backfill trenches without timely watering and curing resulted in cement mortar losing water and cracking.

　　處理方法

　　Handling method

　　①首先將溝槽開裂部位的混凝土或者是水泥砂漿輕輕的剔鑿掉，這時(shí)一定要注意不要破壞里面的管線。

　　① Firstly, gently chisel off the concrete or cement mortar at the cracked part of the trench, and be sure not to damage the pipelines inside.

　　②在溝槽的內(nèi)部使用掛鋼絲，鋼絲網(wǎng)一定要掛嚴(yán)實(shí)。

　　② Use hanging steel wire inside the groove, and the steel wire mesh must be hung tightly.

　　③建議大家使用水泥砂漿抹，涂抹的時(shí)候最起碼要分兩遍來(lái)進(jìn)行。如果通過(guò)水泥砂漿的厚度超過(guò)了30mm，需掛兩層鋼絲網(wǎng)。抹灰第一遍完成以后在表面再掛一次，以此增強(qiáng)其抗裂的能力。

　　③ It is recommended that everyone use cement mortar to apply, and at least two coats should be applied. If the thickness of the cement mortar exceeds 30mm, two layers of steel wire mesh need to be hung. After the first coat of plastering is completed, hang it again on the surface to enhance its crack resistance.
