Description
Technical field
The utility model relates to underground civil construction project technical field, is specifically related to a kind of change rigidity diaphragm wall space enclosing structure.
Background technology
In recent years, flourish along with the domestic city underground engineering construction emerged in large numbers a large amount of deep big foundation pits.Be subjected to the restriction of engineering surrounding enviroment condition, " the cheating in the hole " that is no lack of some asymmetrical large tracts of land abnormity foundation ditches in these foundation ditches and is formed by depth hole.A kind of form of asymmetric foundation ditch is depth hole, and namely foundation ditch both sides height is inconsistent, and the cantilever segment internal force on top and distortion all big, lower support section internal force and distortion are less relatively, and the design of enclosure wall has more highly difficult, causes upper support to be difficult to set up.Be to strengthen its section thickness on the basis of as shown in Figure 1 and Figure 2 conventional board-like diaphragm wall to so existing method of special-shaped foundation ditch, increase the rigidity of enclosure wall, the thickening ground-connecting-wall 1 shown in Fig. 3-5.But owing to be subjected to grooving capacity of equipment and the quantitative limitation of grooving number of devices, diaphragm wall thickness is more big, and grooving equipment is more few, and difficulty of construction is also more big, and cost is also more high, can cause a large amount of wastes.
Summary of the invention
The purpose of this utility model is exactly in order to solve the deficiency that the above-mentioned background technology exists, and a kind of change rigidity diaphragm wall space enclosing structure that can go along with sb. to guard him the different force parts on the different depth in the foundation ditch is provided.
The technical solution adopted in the utility model is: a kind of change rigidity diaphragm wall space enclosing structure, comprise top body of wall and bottom body of wall, and described top body of wall comprises longitudinal wall and the longitudinal wall that is connected as a single entity, longitudinal wall is positioned at the side of longitudinal wall; Described bottom body of wall is that the longitudinal wall of top body of wall extends the part of protruding longitudinal wall downwards.
Further, described longitudinal wall is perpendicular to longitudinal wall.
Further, described longitudinal wall is plane body of wall or folding face wall body, and folding face wall body is " T " font or " L " font, and a folding face of folding face wall body is perpendicular to longitudinal wall.
Further, described top body of wall comprises the longitudinal wall that two sides at least be arranged in parallel, and longitudinal wall is between adjacent longitudinal wall.
The utility model adapts to the requirement of going along with sb. to guard him of asymmetrical special-shaped foundation ditch stress condition different parts by the diaphragm wall of different-stiffness is set, and greatly reduces construction costs and engineering difficulty, has higher economy, technical benefits.The diaphragm wall supporting of big rigidity is adopted in the cantilever segment internal force of foundation ditch middle and upper part and distortion all bigger zone, conventional board-like diaphragm wall supporting is adopted in the less relatively zone of lower support section internal force and distortion, can go along with sb. to guard him the different force parts on the different depth in the foundation ditch preferably.The utility model is simple in structure, and can utilize conventional underground diaphragm wall device to construct low, the easy construction of cost.
