Abstract
The utility model relates to a kind of double doing in the hole of stand column pile and cheats diaphragm wall structure.The purpose of this utility model is to provide simple, lower-cost double the doing in the hole of stand column pile of a kind of structure and cheats diaphragm wall structure, to reduce interim stand column pile quantity, solves the problem that in concrete placings process, diaphragm wall reinforcing cage easily floats.The technical solution of the utility model is: a kind of double doing in the hole of stand column pile cheats diaphragm wall structure, in shallow foundation hole, excavation has deep foundation ditch, the space enclosing structure of this deep foundation ditch adopts diaphragm wall, described diaphragm wall arranges reinforcing cage below deep pit digging scope, it is more than plain concrete wall, it is characterized in that: described plain concrete arranges steel lattice column within the walls, steel lattice column is vertically arranged, this steel lattice column lower end is positioned at below deep pit digging scope, and be fixedly connected with reinforcing cage, steel lattice column upper end rises to ground.The utility model is applicable to municipal administration, industrial and civil architecture.
Description
Technical field
The utility model relates to a kind of double doing in the hole of stand column pile and cheats diaphragm wall structure.Be applicable to municipal administration, industrial and civil architecture.
Background technology
The Deep Foundation Pits such as urban track traffic in recent years and Large Underground space development are progressively toward dark, general orientation development, and in some deep foundation ditchs such as transfer subway station or Large Underground spatial synthesis body etc., often occur that some dig dark comparatively large (>8m), and cheat in the hole of buried depth comparatively dark (cheating base plate buried depth >25m in hole), be limited by the limitation of the water-stop curtain effective lengths such as existing agitation pile, in these holes, pit enclosure structure often needs to adopt diaphragm wall.And consider cost, be convenient to the factors such as the later stage cuts, these diaphragm walls are often designed to half wall, and (namely reinforcing cage is only cheated below excavation scope and is arranged in hole, below be then generally plain concrete wall), so just exist steel concrete conduit be difficult under to diaphragm wall reinforcing cage reserved water smash in hole and due to reinforcing cage do not rise to ground impenetrably the measure such as face ballast prevent from watering smash concrete time the problem such as bottom rising of steel cage.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, simple, lower-cost double the doing in the hole of stand column pile of a kind of structure is provided to cheat diaphragm wall structure, to reduce interim stand column pile quantity, solve the problem that in concrete placings process, diaphragm wall reinforcing cage easily floats.
The technical scheme that the utility model adopts is: a kind of double doing in the hole of stand column pile cheats diaphragm wall structure, in shallow foundation hole, excavation has deep foundation ditch, the space enclosing structure of this deep foundation ditch adopts diaphragm wall, described diaphragm wall arranges reinforcing cage below deep pit digging scope, it is more than plain concrete wall, it is characterized in that: described plain concrete arranges steel lattice column within the walls, steel lattice column is vertically arranged, this steel lattice column lower end is positioned at below deep pit digging scope, and be fixedly connected with reinforcing cage, steel lattice column upper end rises to ground.
Described steel lattice column is cored steel structure, is arranged in reserved the watering of bottom diaphragm wall and smashes hole site.
Two steel lattice columns are symmetrically arranged with, along diaphragm wall axis arranged in every width diaphragm wall.
Between two steel lattice columns, angle steel bridging is set.
Described steel lattice column upper end welding angle steel.
The beneficial effects of the utility model are: the utility model is cheated in diaphragm wall and arranged steel lattice column in hole, make that diaphragm wall is double does stand column pile, greatly save interim stand column pile quantity.Steel lattice column doublely can do and hang muscle when reinforcing cage is transferred, and avoids additional to hang muscle.When the utility model solution diaphragm wall reinforcing cage does not rise to ground, concrete steel conduit is difficult to enter reinforcing cage smoothly and reserves the problem of watering and smashing hole; When solution diaphragm wall reinforcing cage does not rise to ground, the easy On The Floating of diaphragm wall reinforcing cage in concrete placings process.

Fig. 1 is pit enclosure sectional drawing in cheating in the utility model.
Fig. 2 cheats single width diaphragm wall expanded view in hole in the utility model.
Fig. 3 is the enlarged diagram in A portion in Fig. 2.
Detailed description of the invention
In shallow foundation hole 1, excavation has deep foundation ditch 2, and the space enclosing structure of this deep foundation ditch adopts diaphragm wall 3.Diaphragm wall 3 is designed to half wall, namely below deep foundation ditch 2 excavation scope, arranges reinforcing cage 4, is more than plain concrete wall 301.
For cheating Problems existing in diaphragm wall design, construction in hole in the present embodiment, on some subways of summary and municipal engineering practical experience basis, the double form of structure doing stand column pile of a kind of diaphragm wall is proposed, specific as follows:
As shown in Figure 1, steel lattice column 5 is arranged in plain concrete wall 301, makes to cheat in hole that diaphragm wall is double does stand column pile, to save stand column pile quantity.Steel lattice column 5 is vertically arranged, this steel lattice column lower end is positioned at below deep foundation ditch 2 excavation scope, and is fixedly connected with reinforcing cage 4, and steel lattice column upper end rises to ground.
Consider symmetry, every width diaphragm wall 3 arranges two steel lattice columns 5, and according to upper load size, selects steel lattice column model, arrange angle steel bridging 7, to ensure the stability (see Fig. 2) in lifting process between two steel lattice columns 5.Hang muscle when simultaneously two steel lattice columns 5 can be transferred as reinforcing cage 4, and hang muscle without the need to additional, cause waste.
Steel lattice column 5 is cored steel structure, being arranged on reserved the watering of bottom diaphragm wall and smashing hole site, smashing in hole when building concrete by steel lattice column 5 inner space by watering to bottom diaphragm wall under steel conduit.
Steel lattice column 5 top rises to ground, and is welded with angle steel 6 (Fig. 3) in end, so that when building concrete, carries out counterweight, prevent rising of steel cage by end angle steel to diaphragm wall reinforcing cage 4.
The present embodiment be comparatively applicable to along hole in cheat diaphragm wall need to arrange elongated interval stand column pile time, all the other situations can be arranged in conjunction with actual conditions.
