The prefabrication building block is pierced with prestressing tendons, and the prefabrication building blocks are connected mutually via the anchoring of the prestressing tendons. The prefabrication building block is provided with horizontal and vertical pore paths through which the prestressing tendons can pass through. The continuous wall adopts prefabrication members totally without scene secondary casting and maintenance for concrete, so the scene construction of the concrete can be avoided entirely and duration can be shortened greatly. The prestressing can enhance the totality of the structure and save steel simultaneously. The prefabrication building blocks by which the prestressing assembly type underground continuous wall can be formed are also disclosed, and the building block is provided with horizontal and vertical pore paths.
Description
Technical field
The utility model relates to a kind of underground building structure, is specifically related to a kind of assembling diaphragm wall, relates to the blockwork that constitutes this assembling diaphragm wall simultaneously.
Background technology
Existing diaphragm wall has following several:
(1). traditional cast-in-place monolithic diaphragm wall
The traditional grooving of diaphragm wall employing mud off, reinforcing cage hangs, fluid concrete.Adjacent groove section adopts construction joint to connect.This method mud requirement is high, the on-site concrete engineering quantity is big, cell wall easily caves in, and problem such as can occur bag slurry (mud) after the concrete pouring, compactness is not enough, reinforcing bar exposes, percolating water, metope are coarse, particularly in caving grounds such as saturated aqueous grittiness, traditional construction method of underground continuous wall is verified very difficult assurance diaphragm wall wall quality in engineering practice.
(2). assembling and assembled integral diaphragm wall.
It is that elementary cell is built diaphragm wall that such diaphragm wall all adopts prefabricated units.Construction site for the relatively poor easy generation landslide of geology, solved the cast-in-place groove section of Cast-in-situs type diaphragm wall underground concrete and watered the concrete that often produces when smashing and stream phenomenon, also avoided because the bulging phenomenon of the reinforced concrete wall panel that the interior earth fall side of groove causes.Simultaneously to mud require low, the on-site concrete engineering quantity is little.
According to the intersegmental jointing form of prefabricated unit groove, be divided into assembling and assembled integral.The assembling joint is flexible joint, needs on-the-spot slip casting; The joint of assembled integral is rigid joint, needs cast-in-place concrete.Rigid joint can make the adjacent width of cloth of diaphragm wall be linked to be integral body, and it can Transfer of Shear can transmit moment of flexure again, must overlap and satisfy the lap length requirement of standard at the adjacent width of cloth body of wall of textural rigid joint reinforcing bar.And flexible joint generally can not be transmitted horizontal bending moment, and has the joint seepage problem.It does not require that textural adjacent width of cloth body of wall reinforcing bar will overlap yet, thereby joint rigidity is poor.
In addition, the connection between the elementary section also has the bolted mode of employing, as shown in Figure 1, cooperatively interacts between the prefabricated unit groove section 1, and connects as one by flange plate 3 and bolt 2, constitutes diaphragm wall.
Present assembling and assembled integral diaphragm wall, the connection of joint needs on-the-spot slip casting, fluid concrete or bolted mode.And the dry wall section generally adopts elongated wall section at depth direction, and construction weight is big, construction hoisting is difficult.
The utility model content
A technical problem to be solved in the utility model provides a kind of assembling diaphragm wall that does not need cast-in-site and be convenient to construct.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of prestressing force assembling diaphragm wall, be assembled by blockwork, be equipped with presstressed reinforcing steel in the described blockwork, the anchoring by presstressed reinforcing steel between the blockwork interconnects.
Preferably, be provided with horizontal and vertical duct in the described blockwork, described presstressed reinforcing steel is located in the described horizontal and vertical duct.
Preferably, also be provided with anchor slot on the described blockwork, be used for presstressed reinforcing steel is carried out anchoring.
Preferably, described blockwork is a cuboid, is respectively equipped with tenon or groove on its four sides.
Preferably, the seam crossing of described adjacent two blockworks is provided with spline or water-swellable bed course, can improve the water resistance of seam.
Compared with prior art, advantage of the present utility model comprises:
(1) adopts prefabricated units fully, do not need the second pouring and the concrete maintenance of on-site concrete, avoided the construction of on-site concrete fully, greatly the shortage duration;
(2) adopt small-sized prefabricated units, reduce freight and field erected lifting cost and use;
(3) meticulous joint design and adopt prestressing technique can improve the water resistance of joint as the assembly unit means is avoided the percolating water of joint;
(4) compare with existing assembling diaphragm wall, do not need the joint that bolt, pin connection are set, make splicing easy, the efficient height;
(5) adopt suitable worker's method and equipment, grooving, assembling, sinking are finished together;
(6) prestressing force can also improve the globality of structure, saves steel simultaneously.
Another technical problem to be solved in the utility model provides a kind of blockwork that is used to constitute above-mentioned prestressing force assembling diaphragm wall.
In order to solve the problems of the technologies described above, be provided with horizontal and vertical duct in the blockwork of the present utility model, be used to wear presstressed reinforcing steel.
Preferably, also be provided with anchor slot on the described blockwork, be used for presstressed reinforcing steel is carried out anchoring.
Preferably, described blockwork is a cuboid, is respectively equipped with tenon or groove on its four sides.
