The steel inclined throwing support is arranged in a foundation pit, the other end of the steel inclined throwing support is connected with a buttress of a constructed bottom plate, basin-type excavation is mostly adopted for controlling the deformation of the foundation pit, back pressure soil with certain width and height is reserved on the section of the steel inclined throwing support, the steel inclined throwing support is installed after the construction of the bottom plate outside a back pressure soil area is finished, the reserved back pressure soil is excavated after the installation of the steel inclined throwing support is finished, and then the bottom plate at the position is constructed, so that the earthwork of the foundation pit is excavated twice, the bottom plate is constructed twice, the space of the back pressure soil area is smaller, the excavation difficulty of the back pressure soil is larger, the construction period of the whole foundation pit is influenced, and the steel pipe inclined pile support for supporting the foundation pit is used for solving the problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a steel pipe batter pile support for excavation supporting possesses that the construction speed is fast and prevent that the foundation ditch from warping effectual advantage, has solved current support construction steps and has many and lead to the progress slow and prevent the poor problem of foundation ditch deformation effect.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a steel pipe batter pile supports for foundation ditch supporting, includes foundation ditch retaining structure, the surface of foundation ditch retaining structure is poured by the concrete and is had concrete hat beam, one side of concrete hat beam is provided with the steel pipe batter pile telescopic joint, the one end bolt of steel pipe batter pile telescopic joint has connecting elements, and connecting elements's the other end pours into in the concrete hat beam, the other end bolt of steel pipe batter pile telescopic joint has the steel pipe batter pile.
Preferably, the bottom end of the steel pipe inclined pile is welded with a pile tip.
Preferably, a water stop steel plate is welded inside the steel pipe inclined pile.
Preferably, a concrete force transmission belt is poured between the foundation pit enclosure structure and the basement bottom plate.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses a foundation ditch retaining structure, the steel pipe batter pile, the concrete crown beam, the setting of connecting elements and steel pipe batter pile telescopic joint, it is many and lead to the progress to slow and prevent the poor problem of foundation ditch deformation effect to have solved current support construction steps, this support is when using, foundation ditch earthwork open-type excavation can be realized to the foundation ditch that the steel pipe batter pile supported, do not keep the back pressure, the basement bottom plate is under construction once, thereby it is fast to realize the construction speed, and the steel pipe batter pile supports the setting and does not go out the red line in the foundation ditch inboard, the secondary need not be considered and retrieve while the steel pipe batter pile supports and can apply prestressing force, the control foundation ditch that can be better.
