Description
Technical field
The present invention relates to underground civil construction project technical field, be specifically related to a kind of variation rigidity underground continuous wall-enclosure structure.
Background technology
In recent years, flourish along with domestic city underground engineering construction, has emerged in large numbers a large amount of deep big foundation pits.By the restriction of Around ambient conditions, be no lack of some asymmetrical large area abnormity foundation ditches in these foundation ditches and cheated by the depth " cheating in hole " of forming.A kind of form of asymmetric foundation ditch is depth hole, and namely foundation ditch both sides height is inconsistent, the cantilever segment internal force on top and distortion are all comparatively large, lower support section internal force and distortion relatively little, the design of enclosure wall has more highly difficult, causes upper support to be difficult to erection.Be on the basis of the board-like diaphragm wall of routine as shown in Figure 1 and Figure 2, strengthen its section thickness to so existing method of special-shaped foundation ditch, increase the rigidity of enclosure wall, thickening ground-connecting-wall 1 as in Figure 3-5.But owing to being subject to grooving capacity of equipment and the quantitative limitation of grooving number of devices, diaphragm wall thickness is larger, and grooving equipment is fewer, and difficulty of construction is also larger, and cost is also higher, can cause a large amount of wastes.
Summary of the invention
Object of the present invention is exactly the deficiency existed to solve above-mentioned background technology, provides a kind of variation rigidity underground continuous wall-enclosure structure can gone along with sb. to guard him the different force parts on different depth in foundation ditch.
The technical solution used in the present invention is: a kind of variation rigidity underground continuous wall-enclosure structure, comprises upper wall body and lower wall body, and described upper wall body comprises the longitudinal wall and longitudinal wall that are connected as a single entity, and longitudinal wall is positioned at the side of longitudinal wall; Described lower wall body is the part of longitudinal wall to downward-extension protrusion longitudinal wall of upper wall body.
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 upper wall body comprises the longitudinal wall that at least two sides be arranged in parallel, and longitudinal wall is between adjacent longitudinal wall.
The present invention is by arranging the diaphragm wall of different-stiffness, and what adapt to asymmetrical special-shaped foundation ditch stress condition different parts goes along with sb. to guard him requirement, greatly reduces construction costs and engineering difficulty, has higher economy, technical benefits.The cantilever segment internal force of foundation ditch middle and upper part and all larger region of distortion adopt the diaphragm wall supporting of large rigidity, lower support section internal force and the relatively little region of distortion adopt conventional board-like diaphragm wall supporting, can go along with sb. to guard him the different force parts on different depth in foundation ditch preferably.Structure of the present invention is simple, and conventional underground diaphragm wall device can be utilized to construct, and cost is low, easy construction.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, is convenient to be well understood to the present invention, but they do not form restriction to the present invention.
As shown in figs 6-12, the present invention includes upper wall body 4 and lower wall body 5, upper wall body 4 comprises the longitudinal wall 6 and longitudinal wall 7 that are connected as a single entity, longitudinal wall 6 be positioned at longitudinal wall 7 side and perpendicular to longitudinal wall 7.Described lower wall body 5 is the part of longitudinal wall 7 to downward-extension protrusion longitudinal wall 6 of upper wall body 4.
As illustrated in figures 7-11, described longitudinal wall 6 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 7.
As shown in Figure 7, longitudinal wall 6 is plane body of wall, and this plane body of wall forms upper wall body 4 together with longitudinal wall 7, is large rigidity diaphragm wall, and its form of fracture is " T " font.Lower wall body 5 is the part of longitudinal wall 7 to downward-extension protrusion longitudinal wall 6 of upper wall body 4, and its thickness and longitudinal wall 7 uniform thickness, form conventional board-like diaphragm wall.
As shown in Figure 8, longitudinal wall 6 is folding face wall body, and its form of fracture is " T " font.Should form upper wall body 4 by " T " font folding face wall body together with longitudinal wall 7, be large rigidity diaphragm wall, its form of fracture is " work " font.Lower wall body 5 is the part of longitudinal wall 7 to downward-extension protrusion longitudinal wall 6 of upper wall body 4, and its thickness and longitudinal wall 7 uniform thickness, form conventional board-like diaphragm wall.
As shown in Figure 9, Figure 10, longitudinal wall 6 is folding face wall body, and its form of fracture is " L " font.Should form upper wall body 4 by " L " font folding face wall body together with longitudinal wall 7, be large rigidity diaphragm wall, its form of fracture is " fourth " font.The difference of Fig. 9, Figure 10 is that " L " font folding face wall direction is different.Lower wall body 5 is the part of longitudinal wall 7 to downward-extension protrusion longitudinal wall 6 of upper wall body 4, and its thickness and longitudinal wall 7 uniform thickness, form conventional board-like diaphragm wall.
As shown in figure 11, upper wall body 4 comprises the longitudinal wall 7 that two sides be arranged in parallel, and longitudinal wall 6 is between two sides longitudinal wall 7, and perpendicular to longitudinal wall 7, this upper wall body 4 form of fracture is lattice shape.Lower wall body 5 is the part of a longitudinal wall 7 to downward-extension protrusion longitudinal wall 6 of upper wall body 4, and its thickness and longitudinal wall 7 uniform thickness, form conventional board-like diaphragm wall.
As shown in figure 12, be the transverse cross of lower wall body 5, its thickness and longitudinal wall 7 uniform thickness, form conventional board-like diaphragm wall.
As shown in figure 13, the schematic diagram in asymmetric foundation ditch is applied to for variation rigidity underground continuous wall-enclosure structure of the present invention, in foundation ditch, side adopts variation rigidity continuous underground wall structure of the present invention, what longitudinal wall 7 was this space enclosing structure faces foundation ditch part, longitudinal wall 6 is the part away from foundation ditch, opposite side adopts side board type diaphragm wall 3, and centre is connected by internal support of foundation pit 2.
The longitudinal wall 6 of upper wall body 4 of the present invention can be connected for rigid structures by i iron or prince's steel plate with between longitudinal wall 7.Figure shown by the present invention is only a part for variation rigidity underground continuous wall-enclosure structure, and during practical application, this space enclosing structure longitudinal wall may reach hundreds of rice by longitudinal extension.Variation rigidity underground continuous wall-enclosure structure of the present invention can adopt concrete material, and Reinforced Concrete Materials also can be adopted to make, its longitudinal wall 7 and lower wall body 5 perpendicular to the ground.
