Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figures 1 to 5, a kind of underground construction of the present utility model special pair of rib concrete edge wall member, the main abutment wall being used as underground structure.Prestressed concrete abutment wall or non-prestressed concrete abutment wall can be designed to according to different engine requests, namely prestressed reinforcement or nonprestressed reinforcement are set on concrete prefabricated board 1, or simultaneously interval arrangement prestress reinforcing bar and nonprestressed reinforcement on concrete prefabricated board.When side wall concrete is built, this pair of rib abutment wall serves as the effect of template, and this pair of rib abutment wall is again the ingredient of agent structure simultaneously, therefore, does not need to use template, can reduce construction costs when underground construction abutment wall is constructed.
Particularly, a kind of underground construction of the present utility model special pair of rib concrete edge wall member comprises concrete prefabricated board 1, and the top of concrete prefabricated board 1 is provided with the concreting hole 6 that two diameters being positioned at vertical rib 3 both sides are not more than 200mm.Concrete prefabricated board is provided with cross section and is " T " font and orthogonal vertical rib 3 and cross rib 2, reinforcing bar with longitudinal ribs 9 is provided with in the lateral part that rib 3 cross section indulged in " T " font, be provided with cross rib reinforcing bar 8 in the lateral part in " T " font cross rib 2 cross section, flank intensity can be improved; The end of vertical rib 3 and cross rib 2 arranges reserved steel bar 10, to strengthen the connection effect of concrete prefabricated board.Reinforcing bar with longitudinal ribs 9 and cross rib reinforcing bar 8 are nonprestressed reinforcement, and steel-bar arrangement indulges the end of rib and lateral part, cross rib cross section at " T " font, are owing to easily ftractureing in end.Be provided with in the horizontal direction of concrete prefabricated board and reinforcing bar 7 in the plate of cross rib reinforcing bar interlaced arrangement.
The vertical portion that rib cross section indulged in " T " font is arranged with the vertical rib preformed hole 5 that width is 25mm, and the vertical portion in " T " font cross rib cross section is arranged with the cross rib preformed hole 4 that width is 25mm, is used for wearing reinforcing bar.Particularly, the height of vertical rib preformed hole is identical with the vertical Partial Height that rib cross section indulged in " T " font, and the height of cross rib preformed hole is identical with the vertical Partial Height in " T " font cross rib cross section.That is preformed hole does not occupy solid concrete, therefore can not weaken concrete intensity, is beneficial to the transport of plate, lifting.
In use, flank side both can be inside for this pair of rib concrete sidewall, again can be outside, can grasp flexibly according to Practical Project.Particularly, for underground structure, in inside configuration is, namely structural outer is outward towards the side of the soil body.When flank is inside, arrangement prestress reinforcing bar in concrete rib, to improve the anti-crack ability of flank; When flank is outside, arrangement prestress reinforcing bar in concrete slab, improves the anti-crack ability of concrete prefabricated board.
As shown in Figure 6, the special superimposed wall of a kind of underground construction, comprise underground construction special pair of rib concrete edge wall member, concrete 14 has been built between concrete prefabricated board 1 and the soil body 11, stiffening rib is towards soil body side and arrange prestressed reinforcement in concrete prefabricated board, side near the soil body 11 in concrete 14 is provided with side wall reinforcing bar 12, and side wall reinforcing bar 12 is connected with concrete prefabricated board by lacing wire 13.
As shown in Figure 7, the special superimposed wall of a kind of underground construction, comprise underground construction special pair of rib concrete edge wall member, concrete 14 has been built between described concrete prefabricated board 1 and template 15, stiffening rib is towards template side, concrete prefabricated board is towards soil body side and arrange prestressed reinforcement in stiffening rib, and the side near template 15 in concrete 14 is provided with side wall reinforcing bar 12, and side wall reinforcing bar 12 is connected with concrete prefabricated board by lacing wire 13.
