Underground continuous wall construction method
The invention relates to the technical field of foundation construction, and particularly discloses an underground continuous wall construction method. The underground continuous wall construction method comprises the following steps that 1, a groove is excavated in a preset position; 2, a reinforcement cage is hoisted in the groove; and 3, waste plastic modified concrete is poured into the groove, the step 1 and the step 2 are repeated, and after maintenance, an underground continuous wall is obtained. The waste plastic modified concrete is prepared from the following raw materials of, by weight, 220-230 parts of cement, 65-75 parts of coal ash, 70-80 parts of mineral powder, 710-730 parts of fine sand, 980-990 parts of gravel, 6-8 parts of a water reducing agent, 150-160 parts of water and 100-120 parts of modified waste plastic particles. The modified waste plastic particles are obtained by coating the surfaces of waste plastic particles with curing slurry and curing the curing slurry, and the curing slurry is prepared from the following raw materials of, by weight, 40-45 parts of cement, 1-1.5 parts of a cement accelerator and 25-35 parts of water. The underground continuous wall construction method has the advantage that the anti-permeability performance and the compressive strength of the underground continuous wall are improved.
本申请涉及地基施工技术领域，具体公开了一种地下连续墙施工方法，地下连续墙施工方法，包括以下步骤：步骤一，在预设位置开挖成槽；步骤二，在槽内吊放钢筋笼；步骤三，在槽内浇注废塑料改性混凝土，重复步骤一和步骤二，养护后，得到地下连续墙；废塑料改性混凝土由包含以下重量份的原料制成：水泥220‑230份；粉煤灰65‑75份；矿粉70‑80份；细砂710‑730份；碎石980‑990份；减水剂6‑8份；水150‑160份；改性废塑料颗粒100‑120份；改性废塑料颗粒是在废塑料颗粒表面涂覆固化浆经固化后得到，固化浆由包含以下重量份的原料制成：水泥40‑45份，水泥速凝剂1‑1.5份，水25‑35份。本申请具有提高地下连续墙的抗渗性能和抗压强度的优点。
