Abstract
The utility model relates to an underground continuous wall with high stiffness, which is characterized in that the underground continuous wall is composed of a longitudinal wall body and a lateral wall body which are connected into a whole, wherein the lateral wall body is positioned at the side surface of the longitudinal wall body. The stiffness of the underground continuous wall is increased by using an equivalent stiffness method. The utility model has the advantages of simple structure, low cost, convenient construction and full resources, and can be constructed by using conventional underground continuous wall devices.
Description
Technical field
The utility model relates to the diaphragm wall in engineering fields such as civil construction, municipal administration, water conservancy, relates in particular to big rigidity diaphragm wall.
Background technology
Existing steel bar concrete diaphragm wall is generally yi word pattern and arranges that its section (thickness) is subjected to the restriction of grooving capacity of equipment, and maximum ga(u)ge is about 1.5m.In order to improve the rigidity of diaphragm wall, traditional method is to strengthen the section of diaphragm wall (thickness) simply, but owing to be subjected to grooving capacity of equipment and the quantitative limitation of grooving number of devices, become slot thickness big more, grooving equipment is few more, and cost is also high more, the equipment that has even up to several ten million yuan.The grooving equipment of big section (more than the 1.5m) is scarce resource, and the grooving cost is very high.At present, to darker underground construction, for satisfying the requirement of retaining soil, sealing, load-bearing, for reducing calculated height (degree of depth), set up and put anchor pole or interior support, but there are the following problems for these two kinds of methods: (1) anchor pole exists waterproof, corrosion-resistant problem, and the underground construction design life that has is 100 years, and anticorrosion problem is difficult to solve all the time; (2) permanent underground structure adopts anchor pole to have the problem of anchor stress loss; (3) support in and can adopt, but seriously influence soil excavation for the underground support structure.Along with The development in society and economy, because the degree of depth of underground structure is more and more darker, higher requirement has been proposed for the rigidity of underground diaphragm wall, thus the increasing big rigidity diaphragm wall of requirement of engineering.
Summary of the invention:
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, propose a kind of simple in structure, cost is low, the big rigidity diaphragm wall of easy construction, makes it can utilize conventional continuous wall trench underground equipment to construct.
For achieving the above object, the utility model adopts following technical scheme: big rigidity diaphragm wall, it is characterized in that it is made of longitudinal wall that is connected as a single entity and longitudinal wall, and described longitudinal wall is positioned at the side of longitudinal wall.
In such scheme, described longitudinal wall is perpendicular to longitudinal wall.
In such scheme, described longitudinal wall adopts plane body of wall or folding face wall body or curved walls.
In such scheme, the longitudinal wall that has at least the two sides to be arranged in parallel, longitudinal wall is between adjacent longitudinal wall.
The utility model utilizes the method for equivalent stiffness to improve the rigidity of diaphragm wall, and it is simple in structure, cost is low, can utilize conventional underground diaphragm wall device to construct, easy construction, and resource is abundant.
