摘要
为了解决传统混凝土挡墙安全可靠但缺少生态性的问题,在其陡立的临水侧墙面上设置数排生态槽进行景观绿化,可形成具有生态美景、方便落水者攀爬上岸、提供动物栖息空间等优点的混凝土生态挡墙。针对生态槽壁立模、浇筑难度大、施工效率低等问题,提出先阶梯后砌体槽壁的施工方法,并分水上水下两种情况研究了单元生态槽砌体槽壁厚度影响因素及参数确定方法。结果表明:槽壁厚度与槽高、砌体弯曲抗拉强度、水流速、冲刷角度等因素密切相关。工程实例表明,单元生态槽砖砌体槽壁厚度以15 cm为宜,而工程造价仅相当于厚10 cm混凝土的一半,并提出了一组较为理想的生态槽设计数据。
In order to solve the problem that the traditional concrete retaining wall is safe and reliable but lacks ecology,several rows of ecological grooves were arranged on the steep waterfacing side wall surface for landscape greening,which could form a concrete ecological retaining wall with the advantages of ecological beauty,convenience for swimmers to climb ashore and providing animal habitat.Aiming at the problems of formwork erection,difficult pouring and low construction efficiency of ecological tank wall,the construction method of first step and then masonry tank wall was proposed,and the influencing factors and method for determining parameters of brick masonry tank wall thickness of unit ecological tank were studied under water and above water.The results show that the thickness of the groove wall is closely related to the groove height,bending tensile strength of masonry,water flow rate,scouring angle and other factors.The engineering example shows that the wall thickness of brick masonry for unit ecological tank is 15 cm,while the engineering cost is only half of the concrete thickness of 10 cm.A set of ideal design data for ecological tank was proposed.
