地下连续墙施工技术及其质量控制
摘要
地下连续墙施工技术作为一种先进的地下工程结构形式和施工工艺，在深基坑地基工程处理中，特别是高层建筑、重型厂房及大型地下设施等工程中，得到了广泛应用。本文深入探讨了地下连续墙的施工技术及其质量控制方法，旨在为该技术的规范应用与工程质量的提升提供理论依据和实践指导。本文介绍了地下连续墙施工技术的基本原理和工艺流程。地下连续墙施工通过专门的挖槽设备，在泥浆护壁的条件下，沿深基础或地下建筑物周边开挖出具有一定宽度的沟槽，然后吊放钢筋笼，并在充满泥浆的沟槽中浇筑混凝土，形成连续的地下墙体。施工过程中，需经过导墙修筑、泥浆制备与处理、掘进成槽、钢筋笼制安、混凝土浇筑等多个关键工序，各环节相互衔接，共同保证地下连续墙的施工质量和稳定性。本文详细阐述了地下连续墙施工过程中的质量控制要点。在材料选择方面，需确保钢筋、混凝土等材料的质量和性能符合设计要求；在基坑开挖与支护工程中，需采取合适的开挖方法和支护措施，以保证基坑的稳定性；在地下连续墙的安装和施工工艺中，需严格控制测量定位、钢筋绑扎、混凝土浇筑等环节的施工质量；在施工完成后，还需进行质量检验和监测，以确保地下连续墙满足设计要求和规范标准。本文总结了地下连续墙施工技术的优势及其质量控制的重要性。地下连续墙以其高强度、稳定性、适应性强、隔水性好及施工噪音低等特点，在地下工程中发挥着重要作用。然而，其施工难度大、造价高、质量控制点多等特点也要求我们在施工过程中必须严格把控每一个环节，确保施工质量和工程安全。

Abstract
As an advanced structural form and construction technology of underground engineering, the construction technology of underground diaphragm wall has been widely used in the treatment of deep foundation pit, especially in high-rise buildings, heavy plants and large underground facilities. In this paper, the construction technology and quality control method of underground diaphragm wall are deeply discussed, aiming at providing theoretical basis and practical guidance for the standardized application of this technology and the improvement of engineering quality. This paper introduces the basic principle and process flow of underground diaphragm wall construction technology. Through special trenching equipment, under the condition of mud wall protection, trenches with a certain width are excavated along the deep foundation or around the underground building, and then the steel cage is suspended, and concrete is poured in the trench filled with mud to form a continuous underground wall. In the construction process, it is necessary to go through a number of key processes such as guide wall construction, mud preparation and treatment, digging into grooves, steel cage installation, concrete pouring, etc., and each link is connected to ensure the construction quality and stability of the underground continuous wall. This paper expounds the key points of quality control in the construction process of underground diaphragm wall in detail. In terms of material selection, it is necessary to ensure that the quality and performance of steel bars, concrete and other materials meet the design requirements; In the excavation and support engineering of foundation pit, appropriate excavation methods and support measures should be taken to ensure the stability of foundation pit. In the installation and construction process of underground diaphragm wall, the construction quality of measurement and positioning, reinforcement binding and concrete pouring should be strictly controlled. After the completion of construction, quality inspection and monitoring are also required to ensure that the underground diaphragm wall meets the design requirements and specifications. This paper summarizes the advantages of underground diaphragm wall construction technology and the importance of quality control. Underground diaphragm wall plays an important role in underground engineering because of its high strength, stability, strong adaptability, good water insulation and low construction noise. However, its construction difficulty, high cost, quality control points and other characteristics also require that we must strictly control every link in the construction process to ensure construction quality and project safety.
