Description
Technical field
It the utility model is related to the slope protection pile constructing structure in ground construction, more particularly to a kind of bank protection knot with concealed beam
Structure.
Background technology
The deep pit digging of modern construction engineering, it must typically coordinate using supporting construction, with just can ensure that architectural engineering
The normal construction of lower structure, pile-anchor retaining are widely used in pattern foundation pit supporting structure field as a kind of support form of main flow.
In general, anchored pile supporting includes the slope protection pile of some Lin Keng sides for being arranged at foundation pit side-wall, and insertion
Prestress anchorage cable in inter-pile soil body, meanwhile, it is attached between slope protection pile and prestress anchorage cable by steel waist rail.General steel waist
The structure of beam is similar with bank protection pilework, using reinforced concrete structure, i.e., after the completion of bank protection pile driving construction, what is selected
Construction angle-table bracket etc. in several slope protection piles, fixation of the plane then formed using all angle-table brackets as steel waist rail are lifted flat
Face, in the steel reinforcement cage of colligation steel waist rail thereon, and last formwork casting concrete, form steel waist rail.Under this execution conditions, steel
Waist rail at least extends 300 to 400 millimeters from the Lin Keng sides outer wall of slope protection pile to foundation ditch inside, and therefore, this steel waist rail is also referred to as
For plug-in steel waist rail, also, the anchorage of prestress anchorage cable also general provision facing in the side wall of hole to plug-in steel waist rail, drawn with being formed
The stretch-draw prestressing force of tight inter-pile soil.
Headspace is less between underground agent structure and supporting construction, or foundation pit side-wall needs to do bank protection wall, risen
When lining or waterproof, plug-in steel waist rail can not only take the space in foundation ditch, and can hinder the construction of bank protection wall.
Utility model content
The purpose of this utility model is to provide a kind of protective slope structure with concealed beam, and it passes through to slope protection pile and steel waist
The change of the steel reinforcement cage set location of beam so that the hole side wall of facing of steel waist rail flushes with the hole side wall of facing of slope protection pile, reduces steel waist
Occupancy of the beam to space in foundation ditch.
Above-mentioned purpose of the present utility model technical scheme is that：A kind of bank protection knot with concealed beam
Structure, including some slope protection piles, and the steel waist rail being connected between slope protection pile, the hole side wall of facing of the slope protection pile are provided with one
Sunken groove, the steel waist rail are embedded in the groove, and the steel waist rail face hole side wall and slope protection pile face hole side external surface
It is tangent.
By using above-mentioned technical proposal, groove is set in slope protection pile, can be by steel waist rail reinforcing bar when doing steel waist rail
Cage is directly embedded into groove, and using the bottom land of groove as the plane of lifting of steel waist rail, under this structure, steel waist rail " embedded " is extremely
In slope protection pile, concealed beam is formed, compared to plug-in steel breast beam structure, this structure can save the plug-in required occupancy of script steel waist rail
Foundation ditch inner space, meanwhile, the outer surface of steel waist rail and slope protection pile to face hole side external surface tangent so that foundation pit side-wall can
To form a smooth plane, in order to do bank protection wall and waterproof layer etc. thereon.
Preferably, slope protection pile includes bank protection pile cages, and the bank protection pile cages include some vertical muscle and stirrup, Lin Keng
The vertical muscle of side forms the groove to bank protection pile cages internal bend, is fitted together in the groove and is provided with geomery and adapts to
Steel waist rail insertion slope protection pile part cuts filling block, can cut at filling block except described in the bank protection pile cages and fill out
Filled with slope protection pile concrete bodies.
By using above-mentioned technical proposal, during using reinforced concrete pile, the earth-retaining effect and shearing resistance effect of slope protection pile
Preferably, and when welding bank protection pile cages muscle bending is indulged into Lin Keng sides, to avoid place's recess space, then so that filling can be cut
Block is embedded in, and so, when pouring slope protection pile concrete bodies into bank protection pile cages, can cut space that filling block is occupied can not
Slope protection pile concrete bodies are filled, therefore, this position forms groove after removal can cut filling block, is poured compared in slope protection pile
The mode that slope protection pile concrete bodies form groove is cut after building, this mode is more time saving and energy saving, and the groove shapes rule formed
It is whole, do not interfere with the setting-in of steel waist rail.
Preferably, tensioning has prestress anchorage cable in the inter-pile soil between the adjacent slope protection pile, and the prestress anchorage cable is worn
The anchorage for facing hole side wall no more than steel waist rail is installed with the end gone out.
By using above-mentioned technical proposal, after prestressed anchor cable stretching, it is firm inter-pile soil to play a part of, still,
When carrying out spraying mixed to foundation pit side-wall, the flatness of foundation pit side-wall can be influenceed by stretching out the anchorage of the soil body, and by anchorage end set
Face hole side wall no more than steel waist rail, when to steel waist rail casting concrete, anchorage is directly embedded in inside steel waist rail by concrete, with
Prevent anchorage from protruding foundation pit side-wall, hinder the making of bank protection wall.
Preferably, the groove extends radially to the center of slope protection pile along slope protection pile.
By using above-mentioned technical proposal, depth of the groove along slope protection pile radial direction, be steel waist rail width, in order to more reliable
Slope protection pile is connected as a single entity by ground, and depth of groove is extended into bank protection pile center, to increase in the case where not weakening slope protection pile intensity as far as possible
The horizontal width of steel waist rail.
In summary, the utility model has the advantages that：Groove is set in slope protection pile, when doing steel waist rail,
Steel waist rail steel reinforcement cage can be directly embedded into groove, and plane is lifted using the bottom land of groove as steel waist rail, in the structure
Under, in steel waist rail " embedded " to slope protection pile, concealed beam is formed, compared to plug-in steel breast beam structure, this structure can save script steel
The inner space of the foundation ditch taken required for waist rail is plug-in, meanwhile, the outer surface of steel waist rail and slope protection pile face hole side external surface
It is tangent so that foundation pit side-wall can form a smooth plane, in order to do bank protection wall and waterproof layer etc. thereon.
