城市地下水利工程矩形结构竖井施工研究：以东深供水支线龙口阀井区域为例

Research on the construction of rectangular structure vertical shaft in urban underground water conservancy engineering: Taking the Longkou Area of Dongshen Water Supply Branch Line as an example

摘要

城市地下水利工程中，矩形结构竖井的施工过程是一项既复杂又至关重要的工程任务。这项任务对于确保城市水资源的稳定供应、有效防洪排涝以及地下水环境的保护和维护都扮演着极其重要的角色。在进行竖井施工时，竖井的断面布置及其形状、尺寸的确定是一个需要慎重考虑的环节。这些因素的决策不仅受到使用功能和施工条件的影响，还必须综合考虑地质条件、涌水量、提升设备的性能、生产效率以及安全出口的设置等多方面因素。在这些考虑因素中，地质条件显得尤为关键，因为它直接关系到断面布置的形式以及支护结构的设计。目前，在众多水利工程项目中，常用的断面形状主要包括圆形、方形和矩形。其中，圆形断面因其在施工和维护上的便利性以及较高的断面利用率而最为常见。然而，在某些特定的地质条件或城市空间限制的情况下，方形或矩形断面可能更为适宜。

Abstract

In urban underground water conservancy projects, the construction process of a rectangular shaft is a complex and crucial engineering task. This task plays an extremely important role in ensuring the stable supply of urban water resources, effectively preventing floods and draining water, as well as protecting and maintaining the groundwater environment. During the construction of the shaft, determining the layout and shape, as well as the dimensions of the shaft's cross-section, is a step that requires careful consideration. The decision on these factors is not only influenced by the functional use and construction conditions but must also take into account various aspects such as geological conditions, water inflow, the performance of hoisting equipment, production efficiency, and the setting of safety exits. Among these considerations, geological conditions are particularly critical as they directly relate to the form of the cross-section layout and the design of the support structure. Currently, in many water conservancy projects, commonly used cross-section shapes include circular, square, and rectangular. Among them, the circular cross-section is the most common due to its convenience in construction and maintenance and its high cross-section utilization rate. However, in certain specific geological conditions or urban spatial constraints, a square or rectangular cross-section may be more appropriate.
