Description
技术领域technical field

背景技术Background technique
在地下工程中,基坑施工时,为了保证施工的正常进行,需要进行有效的排水,往往会在基坑底面和顶面设置排水沟,有组织的将基坑内的水排出。通常排水沟需要采用矩形砖砌排水沟,但砖砌排水沟一般要经过基础垫层、排水沟两侧砌砖、砖表面刷水泥砂浆等步骤才可完成,施工步骤不仅繁琐,施工周期长,同时地下工程结束后,排水沟所用的砖通常拆卸后当做建筑垃圾处理,造成材料的浪费,不能实现对排水沟所用材料的重复使用,再者,随着砖的价格不断增长,排水沟的建造成本也在逐年增加。In underground engineering, during foundation pit construction, in order to ensure the normal progress of construction, effective drainage is required. Drainage ditches are often set on the bottom and top surfaces of the foundation pit to drain the water in the foundation pit in an organized manner. Usually, the drainage ditch needs to use rectangular brick drainage ditch, but the brick drainage ditch generally needs to go through the steps of foundation cushion, brick laying on both sides of the drainage ditch, and cement mortar on the brick surface. The construction steps are not only cumbersome, but the construction period is long. At the same time, after the underground project is completed, the bricks used in the drainage ditch are usually disassembled and treated as construction waste, resulting in a waste of materials and the reuse of the materials used in the drainage ditch cannot be realized. Furthermore, as the price of bricks continues to increase, the construction of drainage ditch Costs are also increasing year by year.
正是因为排水沟的作用重要,但现有技术不仅增加了施工成本,而且材料重复利用率低,因此需要有新的适用于地下工程用的可回收排水装置。Just because the effect of drainage ditches is important, but existing technology has not only increased construction cost, and material recycling rate is low, therefore needs to have the new recyclable drainage device that is applicable to underground engineering.
另外,还需要在基坑周边设置挡水墙以避免对基坑造成损坏,但目前挡水墙的施工步骤繁琐,施工周期长,且材料不能重复使用,造成工作成本以及材料的浪费,同时,排水沟和挡水墙采用人工砌墙,容易在排水过程中拼接处容易发生渗漏。In addition, it is necessary to install a water retaining wall around the foundation pit to avoid damage to the foundation pit. However, the current construction steps of the water retaining wall are cumbersome, the construction period is long, and the materials cannot be reused, resulting in waste of work costs and materials. At the same time, Drains and retaining walls are artificially built, which is prone to leakage at the joints during the drainage process.
