Abstract
The utility model relates to a waist beam used for a composite soil nailing wall which is composed of three parts including channel steel, a reinforcing mesh and a U-shaped pit surface. The reinforcing mesh is made to be U-shaped and arranged at the U-shaped pit surface. The channel steel is arranged in a U-shaped groove of the U-shaped reinforcing mesh. The U-shaped pit surface is disposed on a slope surface of a deep foundation pit. The waist beam used for the composite soil nailing wall has following advantages: space is saved; the slope surface of the deep foundation pit can be made to be the straight-slope composite soil nailing wall during construction to facilitate construction by a main construction unit and is made smooth so that the slope surface of a side slope is directly made into an outer membrane by the main construction unit; manpower, material and financial resources are effectively saved; and construction period is shortened.
Description
Technical field
The utility model belongs to architectural design field, particularly a kind of for composite soil nailing wall concealed type waist rail.
Background technology
Along with social development and the mankind's progress, the requirement that people use space is more and more higher, a large amount of ultra-deep foundation pits and extra-high start to emerge in large numbers, and common soil-nail wall support can not satisfy the demands, and increasing slope retaining takes composite soil nailing wall mode to carry out supporting.
In Composition Soil Nailing Walls, prestressed anchor need to be locked on steel waist rail, and the selection of steel waist rail is generally channel-section steel.Channel-section steel becomes " recessed " font, and its long limit is parallel, and to be attached to soil nail wall domatic upper, and minor face is perpendicular to domatic.
Along with complexity increase or the raising to space requirement of engineering, for larger space being provided to other the work itemss, soil nail wall often needs to make straight slope, be that slope angle becomes 90 degree, in this case, be attached to outstanding domatic 10～20 centimetres of waist rail on domatic, just can not meet instructions for use, how conserve space, engineering demands just becomes a difficult problem.
Summary of the invention
The purpose of this utility model is the deficiencies in the prior art, proposes a kind of composite soil nailing wall concealed type waist rail that is used for, and it is plane that described concealed type waist rail can make straight domatic in guaranteeing domatic supporting role, has effectively saved engineering construction space.
A kind of composite soil nailing wall concealed type waist rail that is used for is made up of channel-section steel, steel mesh reinforcement and " recessed " type pitted surface three parts; Described steel mesh reinforcement is compiled into " recessed " type, is arranged at " recessed " type pitted surface place, and described channel-section steel is arranged in " recessed " groove of " recessed " steel bar net, and described " recessed " type pitted surface is positioned on deep foundation ditch domatic.
Further, " recessed " groove depth of described " recessed " type pitted surface is greater than channel-section steel bond length.
Further, described steel mesh reinforcement and domatic between have an anti-corrosion measure: lay anti-corrosion material thin layer, or smear cement mortar thin layer, or sprayed mortar thin layer.
Further, on described steel mesh reinforcement, be coated with layer of concrete, in concrete slab, make slope leveling by hidden waist rail, be convenient to follow-up construction.
Further, composite soil nailing wall can be made to straight slope, and slope leveling, not affect the solid space of the required use of follow-up construction.
Further, can complete domatic on polish by cement mortar, the domatic exterior sheathing as agent structure is used.
One described in the utility model is for composite soil nailing wall concealed type waist rail, and its advantage is: can conserve space, can be by the domatic deep foundation ditch straight slope composite soil nailing wall of making when construction, and be convenient to the construction of main body construction unit; Slope leveling, does straight slope composite soil nailing wall at a lot of engine requests, and slope leveling, makes main body construction unit directly make exterior sheathing with side slope surface, can effectively save human and material resources and financial resources, shortens the construction period.
Accompanying drawing explanation
Fig. 1 schematic diagram for composite soil nailing wall concealed type waist rail described in the utility model;
In figure: 1, channel-section steel, 2 steel mesh reinforcements, 3, " recessed " type is domatic.
The specific embodiment
As shown in Figure 1, a kind of composite soil nailing wall concealed type waist rail that is used for is made up of channel-section steel 1, steel mesh reinforcement 2 and " recessed " type pitted surface 3 three parts; Described steel mesh reinforcement 2 is compiled into " recessed " type, is arranged at " recessed " type pitted surface 3 places, and described channel-section steel 1 is arranged in " recessed " groove of " recessed " steel bar net 2, and described " recessed " type pitted surface 3 is positioned on deep foundation ditch domatic.
Use a kind of mode for composite soil nailing wall concealed type waist rail described in the utility model to be:
During to prestressed anchor construction part, start to repair slope at slope excavation, repair a groove at prestressed anchor place, the degree of depth of described groove is greater than channel-section steel bond length.Then start to compile steel mesh reinforcement, according to slope shape, also weave into the shape of groove at groove steel mesh reinforcement.Steel mesh reinforcement is finished rear pore-forming, is lowered to steel strand, slip casting.
After above-mentioned steps, can have two kinds of modes to make waist rail according to actual conditions:
The first: if the useful life that composite soil nailing wall uses is short, do not consider the impact that in the short time, steel mesh reinforcement is corroded, can waist rail be directly installed on steel mesh reinforcement, then pad, anchor head, ground tackle are installed.After installing, carry out stretch-draw, continue lower step operation.
The second: longer if the useful life that composite soil nailing wall uses requires, need to consider the impact that steel mesh reinforcement is corroded.Can between 3 and 2, float spray one layer concrete, or smear cement mortar, or lay anticorrosion thin layer, then settle steel waist rail, continue subsequent handling, or in groove, under channel-section steel, lay the thin layer of one deck anti-corrosion material.
Waist rail described in above-mentioned is channel-section steel.
Claims (5)
1. one kind is made up of channel-section steel, steel mesh reinforcement and " recessed " type pitted surface three parts for composite soil nailing wall concealed type waist rail; Described steel mesh reinforcement is compiled into " recessed " type, is arranged at " recessed " type pitted surface place, and described channel-section steel is arranged in " recessed " groove of " recessed " steel bar net, and described " recessed " type pitted surface is positioned on deep foundation ditch domatic.
2. one as claimed in claim 1, for composite soil nailing wall concealed type waist rail, is characterized in that: " recessed " groove depth of described " recessed " type pitted surface is greater than channel-section steel bond length.
3. one as claimed in claim 1 for composite soil nailing wall concealed type waist rail, is characterized in that: described steel mesh reinforcement with domatic between have an anti-corrosion measure: laying anti-corrosion material thin layer, or smear cement mortar thin layer, or sprayed mortar thin layer.
