Description
Technical Field
The utility model relates to an anti structure technical field that floats of underground tunnel especially relates to an anti structure that floats of underground continuous wall and roof combination.
Background
With the rapid development of cities in China, deep foundation pit engineering, particularly main foundation pits of subway stations, emerge in large quantities like spring bamboo shoots after rain. In the dense area of municipal pipeline, can't apply as the capping beam, utilize underground structure and earthing dead weight to hardly satisfy anti floating requirement. Therefore, in order to develop an underground space and ensure the stability of an underground structure, the combination of the underground continuous wall and the top plate for anti-floating design has important significance.
At present, anti-floating measures of deep foundation pit engineering mainly have two modes: firstly, arranging uplift piles under a station bottom plate; and secondly, a capping beam is arranged to be tightly attached to the underground continuous wall and the waterproof layer of the top plate. The former needs to specially treat the joint of the uplift pile and the bottom plate, and if the treatment is improper, water leakage is easily caused, and the engineering quality is seriously influenced; the latter needs to embed a large amount of reinforcing bar connectors in advance, and the site operation can not avoid the reinforcing bar connectors to shift, and the construction is difficult and can not guarantee the construction quality.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an anti structure of floating that underground continuous wall and roof combine that the atress is clear and definite, construction convenience, cost are lower.
In order to achieve the above object, the utility model discloses an anti structure of floating that underground continuous wall and roof combine's concrete technical scheme is:
an anti-floating structure of a combination of an underground diaphragm wall and a roof, comprising: the underground continuous wall is internally provided with underground continuous wall reinforcing steel bars; the top plate is arranged above the underground continuous wall, and top plate steel bars are arranged in the top plate; the galvanized steel plate is arranged at the joint of the underground diaphragm wall and the top plate, round holes are formed in the galvanized steel plate, underground diaphragm wall steel bars penetrate through the round holes of the galvanized steel plate and are welded with the top plate steel bars and the galvanized steel plates respectively, so that the top plate and the underground diaphragm wall form an integral structure to meet the anti-floating requirement, the underground diaphragm wall steel bars penetrate through the round holes of the galvanized steel plates and are welded with the galvanized steel plates together, the galvanized steel plates ensure the waterproof sealing performance of the joint of the underground diaphragm wall and the top plate, the underground diaphragm wall steel bars are welded with the top plate steel bars together, the structural integrity can be ensured without embedding a steel bar connector, and the construction is convenient.
Furthermore, the aperture and the pitch of the round holes are the same as the diameter and the pitch of the underground continuous wall steel bars.
Furthermore, the underground continuous wall steel bars are longitudinally arranged.
Further, the roof reinforcing bar is for transversely setting up.
Further, the top plate is a precast concrete top plate or a cast-in-place concrete top plate.
Further, the underground continuous wall is cast by concrete.
The utility model discloses an anti structure of floating of underground continuous wall and roof combination's beneficial effect lies in, pass the galvanized steel sheet respectively through underground continuous wall reinforcing bar with the galvanized steel sheet, the welding of roof reinforcing bar is in the same place, make roof and underground continuous wall form an overall structure, concrete placement is wholly carried out with underground continuous wall to the roof, thereby satisfy the anti requirement of floating in the underground, should resist that to float the structure atress clearly and definitely, the cost is lower, it plugs into the ware to need not pre-buried reinforcing bar, convenient construction, the pipeline of roof top is not influenced simultaneously, improve city underground space utilization.
