Description
Technical Field
The utility model relates to a foundation ditch engineering technical field specifically is a novel foundation ditch structure of foundation ditch construction usefulness.
Background
The measures such as soil retaining structure, underground water control, environmental protection and the like required for ensuring the safety and stability of an underground space formed by downward excavation of the ground during the construction of the underground structure are called as foundation pit engineering, and the foundation pit engineering is system engineering integrating geological engineering, geotechnical engineering, structural engineering and geotechnical testing technology. The main content is as follows: engineering investigation, supporting structure design and construction, earth excavation and backfilling, underground water control, information construction, surrounding environment protection and the like. The simplest and most economical method for foundation pit construction is slope excavation, but the method is often limited by site conditions and the surrounding environment, so that a supporting system needs to be designed to ensure the smooth construction and better protect the surrounding environment. When the foundation pit is constructed, the waist beam is required to be adopted to support the foundation pit supporting structure, more waist beams are required to be built for better supporting the foundation pit supporting structure, so that the complexity of the foundation pit supporting structure is increased, a large number of waist beams are built, and the period of foundation pit engineering is greatly increased.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Not enough to prior art, the utility model provides a novel foundation ditch structure of foundation ditch construction usefulness has solved the problem that exists among the above-mentioned background art.
(II) technical scheme
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel foundation ditch structure of foundation ditch construction usefulness, includes the foundation ditch body, the right side of foundation ditch body is fixed with the manual bored concrete pile that digs, the manual top of digging the bored concrete pile is fixed with the guan liang, just the pile body from the top down of the manual bored concrete pile that digs is fixed with a plurality of prestressed anchorage cable.
Preferably, the outer side walls of the upper prestressed anchor cable and the lower prestressed anchor cable are positioned inside the manual hole digging cast-in-place pile and are fixedly provided with embedded pipes.
Preferably, double I-shaped steel is fixed between the foundation pit body and the manual hole digging cast-in-place pile on the left side of the outer wall of the middle prestressed anchor cable.
(III) advantageous effects
The utility model provides a novel foundation ditch structure of foundation ditch construction usefulness possesses following beneficial effect:
(1) The utility model discloses a set up a plurality of prestressed anchorage cable on the manual work is dug the hole bored concrete pile to set up the pre-buried pipe and replace the waist rail on the prestressed anchorage cable of upper and lower side, set up the waist rail simultaneously on middle prestressed anchorage cable, the form that has the waist rail and do not have the waist rail to combine is adopted like this, when guaranteeing foundation ditch supporting structure's stability, has also reduced putting up of waist rail, has simplified foundation ditch supporting structure's numerous and diverse degree, and has shortened foundation ditch engineering's construction cycle.
(2) The utility model discloses a prestressed anchorage cable's form supports the underground structure, has reduced the clearance in the fertile groove of foundation ditch body outward to after foundation ditch engineering is accomplished, need not backfill the fertile groove, the construction cycle who has shortened foundation ditch engineering like this further makes things convenient for constructor to be under construction to foundation ditch engineering more.
