Precipitation construction method of impermeable interlayer
The invention relates to a precipitation construction method for an impermeable interlayer, which comprises the following steps of: during foundation pit construction, when an excavation slope encounters the impermeable interlayer, constructing a water stop wall positioned below the impermeable interlayer on the excavation slope; and a horizontal dewatering well is drilled in the impermeable interlayer from the excavation slope surface, and dewatering is conducted on the impermeable interlayer through the horizontal dewatering well till foundation pit construction is completed. According to the dewatering construction method for the impermeable interlayer, a solution is provided for emergencies in the foundation pit construction process, water and soil at the impermeable layer are prevented from flowing into the foundation pit through the arranged water stop wall, dewatering is conducted on the impermeable interlayer through the horizontal dewatering well, the situation that water in the impermeable interlayer flows into the foundation pit is avoided, and the foundation pit is protected. And smooth foundation pit construction is ensured. The construction method is convenient to operate and good in dewatering effect.
本发明涉及一种不透水夹层的降水施工方法，包括如下步骤：在基坑施工中，于开挖坡面遇到不透水夹层时，于开挖坡面上施做一道位于所述不透水夹层下方止水墙；于开挖坡面向所述不透水夹层内打设水平降水井，利用所述水平降水井对所述不透水夹层进行降水，直至基坑施工完成。本发明提供了一种不透水夹层的降水施工方法，为基坑施工过程中遇到的突发情况提供解决方案，利用设置的止水墙防止不透水层处的水土流入基坑内，利用水平降水井对不透水夹层进行降水，避免不透水夹层内的水流入基坑内，保证基坑施工的顺利进行。本发明的施工方法操作方便，降水效果好。
