复合井盖基层破裂的原因及预防

来源:/添加时间:2018-09-18 14:30:24

目前市场上对于井盖这种产品的需求越来越大了。但与此同时出现的问题也愈发的明显了起来,诸如井盖失窃、井盖损坏、井盖价格过高等等情况纷至沓来,那么为了解决这些问题复合井盖应运而生,下面就来讲一下关于复合井盖基层破裂的原因及预防。

There is a growing demand for such products in the market. But at the same time, the problems are becoming more and more obvious, such as the stolen cover, cover damage, cover prices are too high and so on, so in order to solve these problems, composite well cap emerged, the following on the composite well cap base fracture reasons and prevention.

一、复合井盖基层破裂的原因

1. The cause of the fracture of the composite manhole cover.

1、基层问题主要是地面起砂严重、基层强度不高、基层开裂、产生空鼓后,经重压产生裂缝。

1. Grass-roots problems are mainly serious ground sand, base strength is not high, base cracking, after the occurrence of vacancy, cracks produced by heavy pressure.

2、复合井盖施工中水泥自流平加水过多、基层没有打扫干净,界面剂使用不当造成表面失水过快,产生干缩裂缝,水分快速流失,水泥水化反应没有充分进行,也会产生表面粉化,后期养护不当也会引起起鼓开裂。

2. In the construction of composite well cover, excessive water addition in cement self-leveling, no clean base, excessive surface water loss, drying shrinkage cracks, rapid water loss, cement hydration reaction is not fully carried out, surface powdering will also occur, and improper maintenance will also cause bulging and cracking.

3、施工厚度越大,累计应力越大,起鼓开裂风险也会加大。施工厚度5.0mm以内,这种膨胀收缩造成的内应力尚不足以造成直接起鼓。

3, the greater the construction thickness, the greater the cumulative stress, and the risk of cracking will increase. Within the thickness of 5.0mm, the internal stress caused by the expansion contraction is not enough to cause the drumming directly.

4、有些复合井盖自流平水泥超过5mm厚度就有开裂起鼓风险,这是由自流平收缩膨胀所致,而少许工人不知道或不在意收缩膨胀的危害。

4. Some composite wellbore caps with self-leveling cement thickness exceeding 5mm have the risk of cracking and bulging, which is caused by self-leveling shrinkage and expansion, and a few workers do not know or care about the harm of shrinkage and expansion.

二、复合井盖基层破裂的预防

Two. Prevention of base break of compound well cover

1、为保持盖外表的美观,表面花纹和字迹的清晰,以沥青路面施工时应用簿铁皮或木板覆盖在井盖上,黑色井盖也可用废机油等刷涂盖面,防止沥青喷在井盖上。

1. In order to keep the appearance of the cover beautiful, clear surface patterns and handwriting, cover the well cover with thin sheet of iron or wood during the construction of asphalt pavement, and the black well cover can also be brushed with waste oil to prevent asphalt from spraying on the well cover.

2、井盖的砖砌体砌筑,应按照设计院设计的井盖尺寸确定其内径或者说长X宽、方圆,也可相应参照标准执行,并在井盖外围浇铸宽为40cm的混凝土保护圈,保养期要在10天以上。

2. Brick masonry masonry of the well cover should be built according to the size of the well cover designed by the design institute to determine its internal diameter or length X-wide, square circle, and also can be carried out according to the corresponding reference standards, and cast a 40 cm wide concrete protective ring around the well cover, the maintenance period should be more than 10 days.

3、在沥青路面上安装井盖时,一定要注意避免施工机械直接碾压井座,在路面整体浇铸时,应予在路面预留比井座略大的孔,在沥青铺完后安置。

3. When installing the well cover on the asphalt pavement, we must pay attention to avoiding the construction machinery to roll the well base directly. When casting the whole pavement, we should reserve the hole slightly larger than the well base on the pavement and place it after the asphalt paving.

4、混凝土将井座浇铸或沥青铺设后,应及时将井盖打开清洗,避免砂浆或沥青将检查井盖与座浇成一体,以免影响日后开启。

4. After concrete pouring or asphalt laying, the well cover should be opened and cleaned in time, so as to avoid mortar or asphalt pouring the inspection well cover into a whole, so as not to affect the future opening.

以上就是关于复合井盖基层破碎的原因及预防,希望能对大家有所帮助。

The above is the reason and prevention of the breakage of the compound manhole cover, and I hope it can help everyone.
