Description
Technical field
The utility model relates to the skeleton for diaphragm wall.
Background technology
Diaphragm wall is Foundation Design.During construction, adopt a kind of trench machine on the ground, along the periphery axis of deep excavation project, under mud off condition, excavate out a long and narrow deep trouth.After clear groove, install reinforcing cage in groove, then builds up a unit groove section with tremie method underwater concreting with tremie method.So carry out piecemeal, build up one continuous print steel concrete wall in underground, as intercepting water, antiseepage, load-bearing, water-retaining structure.Diaphragm wall is applicable to pumping plant, pond; Building foundation pit; Oil cellar and warehouse; Municipal administration pipe trench and culvert; The vertical shaft of the engineerings such as shield structure; Various deep foundation and pile foundation; Harbour, shore protection and dry dock; The impervious wall of water conservancy and hydropower, surface mine and tailing dam (pond) and environment-friendly engineering; Underground structure (such as underground railway, road tunnel, underground parking and underground street, shop and underground substation etc.) etc.
Diaphragm wall is owing to arranging and below ground, and the degree of depth reaches tens meters, and even more than 100 meters, subterranean wall is darker, also more affects by ground water seepage.Because diaphragm wall is constructed piecemeal, adjacent two section concrete junctions easily form seam, cause leaking.Solve seepy question, a kind of way is wherein the joint adopting special construction.But in most of occasion, even if joint design is good again, still thoroughly seepy question cannot be solved.Trace it to its cause, transfer joint for convenience, leave certain gap between joint and cell wall, when transferring reinforcing cage after-pouring, the concrete of fluid form can be walked around joint and flow to another section of adjacent reinforcing cage place.When building next section again, the concrete of newly building cannot form one with the concrete to stream before, and both can cause forming seam difference in setting time, and seam becomes the main cause that diaphragm wall leaks.

Preferably, described joint is also provided with flow-stopping plate; Described flow-stopping plate extends along described length of reinforcing cage direction and covers a part of reinforcing cage.
The skeleton for diaphragm wall in the utility model, isolation is adopted to be arranged on outside reinforcing cage, can effectively prevent from producing when this section of reinforcing cage concreting streaming, the concrete preventing this section from building streams to another section of adjacent reinforcing cage place, also the concrete would not poured into a mould respectively at adjacent reinforcing cage can not contact, also would not produce seam, thus solve seepy question.
Accompanying drawing explanation
Fig. 1 is that joint and reinforcing cage are transferred to the structural representation in groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
The utility model is arranged in conjunction with diaphragm wall skeleton that to arrange in groove 10 around foundation ditch be example explanation.As shown in Figure 1, for the skeleton of diaphragm wall, comprise multiple joint 20 and multistage reinforcing bar 30.Reinforcing cage 30 one or both ends are provided with joint 20, determine depending on the shape of diaphragm wall and the position of reinforcing cage 30.If diaphragm wall is ring seal structure, joint 20 is all set at reinforcing cage 30 two ends, between every two joints 20, is provided with reinforcing cage 30.If diaphragm wall is nonocclusive structure, then one section of reinforcing cage 30 along diaphragm wall length direction two only arranges joint in one end.Joint 20 leaks in junction after fill concrete for preventing adjacent two sections of reinforcing cages 30.Joint 20 comprises at least one plate body 21.On plate body 21, side is provided with wing plate 23; Opposite side arranges guiding device 50.
Spacer assembly is provided with between the cell wall 11 of reinforcing cage 30 and groove 10.Spacer assembly two ends are connected on reinforcing cage 30 end or described joint 20, at least one side closed by described reinforcing cage 30, for stopping that the concrete be filled in this reinforcing cage 30 streams to adjacent reinforcing cage place.Spacer assembly is flexible sheet material.In preferred exemplary as shown in the figure, spacer assembly is geotextiles 40.Geotextiles 40 two ends are connected on two joints 20.Meeting pitted surface and meeting native face of reinforcing cage 30 is provided with geotextiles 40, and the both sides of reinforcing cage 30 are all closed.Reinforcing cage 30 surrounds by two pieces of geotextiles 40 and two joints 20.Geotextiles 40, for stopping concrete, prevents from building concrete in wherein one section of reinforcing cage 30 place from streaming between joint 20 and the cell wall 11 of groove 10 to adjacent reinforcing cage 30.When first opening reinforcing cage 30 concreting of 100, the geotextiles 40 first opening 100 sections can prevent concrete from the reinforcing cage 30 streamed between joint 20 and cell wall 11 to closed 200, thus can avoid being cast in and first open a concrete at 100 places and contact with the concrete being cast in closed 200 place and produce seam, avoid danger of leaking.
Geotextiles 40 both adopted connector with the connection of joint 20, and as bolt 41 and nut 42 combine, or screw connects, and other fastening devicess also can be adopted to connect.In preferred exemplary as shown in the figure, some geotextiles 40 adopt bolt 41 to be connected with wing plate 23 with nut 42 combination.Bolt 41 is through wing plate 23 and geotextiles 40, and the nut 42 be threaded connection, is connected geotextiles 40 end with joint 20.Geotextiles 40 also can adopt iron wire (not shown) with the connection of reinforcing cage 30.Iron wire is utilized to pass geotextiles 40 by its bolt on reinforcing cage 30.
The plate body 21 of joint 20 is also provided with flow-stopping plate 70.Flow-stopping plate 70 end is arranged on plate body 21, extends, cover part reinforcing cage 30 along reinforcing cage 30 length direction.Flow-stopping plate 70 also can play prevent from streaming effect.In preferred exemplary as shown in the figure, guiding device 50 is provided with guide groove 51.Flow-stopping plate 70 end is provided with lead 71.Lead 71 is inserted in guide groove 51.
Geotextiles 40 is first arranged on joint 20 and reinforcing cage 30, transfers in dead slot 10 with joint 20 and reinforcing cage 30.Fill concrete, makes concrete wrap reinforcing cage 30.Groove 10 between every two joints 20 is one section, independently builds.One section of diaphragm wall is formed after concrete setting.After the completion of one section of diaphragm wall, then repeat above step next section of diaphragm wall is set, until diaphragm wall length meets the requirements.As shown in Figure 1, first first open 100 place's concretings at two sections, then at closed 200 place's concretings.
The skeleton for diaphragm wall in the utility model, the spacer assembly arranged outside reinforcing cage can effectively prevent concrete from streaming, and therefore also can not form unnecessary seam and the danger of leaking.In the construction of diaphragm wall process taking section construction, when especially adjacent two periods of construction of diaphragm wall interval times are longer, the utility model effect is especially obvious.Adopt guiding device 50, add the facility that joint 20 is laid with reinforcing cage 30.
Take Fig. 1 as reference, length direction described in the utility model is left and right directions, and width is above-below direction; Depth direction is perpendicular to paper direction.
Geotextiles in the utility model can also adopt steel sheet, sheet iron plate or nonmetal thin plate to replace.Steel sheet, sheet iron plate or nonmetal thin plate can adopt welding or securing member to be connected with joint or reinforcing cage end.
Embodiment in the utility model, only for being described the utility model, does not form the restriction to right, other equivalent in fact substituting, all in the utility model protection domain that those skilled in that art can expect.
