Description
技术领域 technical field
本实用新型涉及一种地下工程，特别涉及一种地下防水工程的止水结构。 The utility model relates to an underground project, in particular to a water stop structure for an underground waterproof project.
背景技术 Background technique
现有的水利或其他地下防水工程施工中，其相邻结构均采用铜片嵌装进行止水，目前公知的施工方法都是 “预埋法”，即在砼浇筑前预埋铜片的一半、另一半留作相邻结构连接的方法。采用“预埋法”施工，先要开挖施工，开挖作业会对周围的地基造成不良影响，会导致周边建筑物不均匀沉降等问题；为克服该问题，现有技术中还有一种逆作法施工方法，即先从地面向下开挖一定深度的槽孔，相邻槽孔之间呈相接圆设置，钻孔完成后向所钻孔中灌注混凝土，固化后构成坚固的地下连续墙，地下连续墙一般围合成封闭的形状，构建完成后再进行开挖施工，可避免对周围建筑物的不良影响，其应用在地铁站、地下室、支护结构等建设中，其带来的问题是铜片止水无法预埋，目前只能采用膨胀橡胶安装于相邻结构的伸缩缝间，利用膨胀橡胶的膨胀来止水。其受现场条件、建筑物表面平整度、连接方法、自身强度和寿命等影响，很难有效解决渗漏问题。 In the construction of existing water conservancy or other underground waterproofing projects, the adjacent structures are all embedded with copper sheets to stop water. At present, the known construction methods are all "pre-embedded methods", that is, half of the copper sheets are pre-embedded before concrete pouring. , The other half is reserved as a method for connecting adjacent structures. Using the "pre-embedded method" construction requires excavation first, and the excavation operation will cause adverse effects on the surrounding foundations and cause problems such as uneven settlement of surrounding buildings; in order to overcome this problem, there is also a reverse The method of construction is to excavate slots of a certain depth from the ground, and the adjacent slots are arranged in a contiguous circle. After the drilling is completed, concrete is poured into the drilled holes, and a solid underground continuous wall is formed after curing. , the underground diaphragm wall generally forms a closed shape, and excavation construction is carried out after the construction is completed, which can avoid adverse effects on surrounding buildings. It is used in the construction of subway stations, basements, and supporting structures. The problems it brings The reason is that the copper sheet water stop cannot be pre-embedded. At present, expansion rubber can only be used to install between the expansion joints of adjacent structures, and the expansion of the expansion rubber can be used to stop the water. It is difficult to effectively solve the leakage problem due to the influence of site conditions, building surface flatness, connection method, self-strength and life span.

其进一步改进在于所述环氧砂浆层表面涂抹有封闭表层。 Its further improvement is that the surface of the epoxy mortar layer is coated with a closed surface layer.
所述止水件安装槽的深度为6~7cm，止水件安装槽的高度为12~15cm。 The depth of the installation groove of the water stop is 6-7cm, and the height of the installation groove of the water stop is 12-15cm.
本实用新型中，环氧树脂打底层可加强混凝土和环氧胶泥之间的连接性能；环氧胶泥是由环氧树脂和乙二胺固化剂组成，为塑性材料，其粘结能力强，固化时间易于控制，连接后水密性能好，能与铜片可靠连接；而环氧砂浆为干硬性材料，便于填塞。环氧砂浆初步固化后，在其表面涂抹一层环氧树脂涂料形成封闭表层可以填满环氧砂浆的气孔和缝隙，达到全面封闭的效果。最后，通过将铜片止水件的另一侧浇筑在相邻结构的混凝凝土内，在铜片止水件的另一侧也能达到良好的密封效果，铜片止水件的折弯部留在伸缩缝内，可补偿沉降差、收缩变形等情况，保证具有良好的密封防水效果。本结构用于逆作法地下防水工程的施工中，具有与预埋法同样的密封防水效果。 In the utility model, the epoxy resin primer can strengthen the connection performance between the concrete and the epoxy mastic; the epoxy mastic is composed of epoxy resin and ethylenediamine curing agent, which is a plastic material with strong bonding ability and is easy to cure. The time is easy to control, the watertight performance is good after connection, and it can be reliably connected with the copper sheet; while the epoxy mortar is a dry hard material, which is easy to fill. After the epoxy mortar is initially cured, apply a layer of epoxy resin paint on its surface to form a closed surface layer that can fill the pores and gaps of the epoxy mortar to achieve a comprehensive sealing effect. Finally, by pouring the other side of the copper waterstop into the concrete of the adjacent structure, a good sealing effect can also be achieved on the other side of the copper waterstop. The bent part stays in the expansion joint, which can compensate for poor settlement, shrinkage deformation, etc., and ensure a good sealing and waterproof effect. The structure is used in the construction of the underground waterproof project by the reverse method, and has the same sealing and waterproof effect as the pre-embedded method.
