Plastic concrete and method for constructing vertical diaphragm wall
The invention discloses plastic concrete, a vertical anti-seepage wall constructed by the plastic concrete and a construction method of the vertical anti-seepage wall. The plastic concrete is prepared from the following components in parts by mass: 440 to 460 parts of water, 155 to 185 parts of cement, 35 to 73 parts of modified bentonite, 62 to 203 parts of limestone powder and 1320 to 1380 parts of machine-made sand. The construction method comprises the following steps: staking out in survey and constructing a guide wall; dividing plates and constructing in sections; preparing wall protecting slurry; digging a groove; pouring concrete and preparing an anti-seepage wall; and verifying drilling of the diaphragm wall. According to the method, the construction process of the plastic concrete diaphragm wall is improved, so that the plastic concrete diaphragm wall can be more efficiently, stably and fully applied in enclosing a polluted site or controlling a high-permeability dam, the grooving guarantee rate is greatly increased, the project progress is fast, interference factors are few, various resources can be well utilized, and the method is suitable for popularization and application. And meanwhile, a monitoring program after the wall is formed is standardized, and the quality problem caused by improper construction is avoided.
本发明公开了一种塑性混凝土及构建垂直防渗墙及其构建的方法。所述塑性混凝土，包括以下质量份计的组分：水440‑460份、水泥155‑185份、改性膨润土35‑73份、石灰石粉62‑203份、机制砂1320‑1380份。构建方法包括：测量放样及导墙施工；板块划分及分段建造；护壁泥浆配制；沟槽开挖；混凝土浇筑及防渗墙制备；防渗墙验证钻孔。本发明通过对塑性混凝土防渗墙施工流程的完善，使得塑性混凝土防渗墙可以更高效、稳定地在围封污染场地或控制高渗透性水坝中得到充分应用，大大提高了成槽保证率，工程进度快、干扰因素少、各种资源能较好的利用，形成良好的经济效应，同时规范了成墙后监测程序，避免因不当施工产生的质量问题。
