Description
Technical Field
The utility model belongs to the technical field of excavation supporting, concretely relates to deep basal pit supporting drainage structures.
Background
The foundation pit is a soil pit excavated at the design position of the foundation according to the elevation of the foundation and the plane size of the foundation. Before excavation, an excavation scheme is determined according to geological and hydrological data and by combining the conditions of buildings nearby the site. The deep foundation pit supporting structure is a supporting structure adopted for the bottom wall of the deep foundation pit and the surrounding environment in order to ensure the safety of the construction of an underground structure and the surrounding environment of the deep foundation pit.
In the correlation technique, before the construction is strutted to the foundation ditch, constructor usually can carry out the drainage to the deep basal pit, but rainfall precipitation etc. causes the ponding once more of foundation ditch diapire very easily, soaks the foundation ditch bottom and influences the support intensity of foundation ditch bottom, consequently, how to improve the problem that foundation ditch support drainage is the urgent need of solving at present.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical problem, the utility model provides a deep basal pit struts drainage structures, the concrete scheme is as follows:
a deep foundation pit supporting drainage structure comprises a hollow L-shaped supporting plate frame, wherein a plurality of drainage pipes penetrate through the rear side of a vertical section of the L-shaped supporting plate frame; the two ends of the drain pipe are sealed, the drain pipe comprises a pipe body, a plurality of water seepage holes are uniformly distributed on the surface of the pipe body outside the L-shaped supporting plate frame, a water outlet is formed in the bottom of the pipe body inside the L-shaped supporting plate frame, and a coarse filter screen and a fine filter screen are sequentially arranged inside the pipe body from outside to inside; the bottom of the vertical section of the L-shaped supporting plate frame is sequentially provided with a sandstone layer, a nylon net layer and a steel wire mesh layer from top to bottom; and the L-shaped supporting plate frame is also provided with a drainage pump for draining accumulated water in the L-shaped supporting plate frame.
Based on the above, the rear side of L type supporting plate frame still is equipped with multichannel strengthening rib.
Based on the above, the rear side and the bottom of L type supporting plate frame all are equipped with many stock.
The utility model discloses relative prior art has substantive characteristics and progress, specifically speaking, the utility model has the following advantages:
the utility model discloses can guarantee the stability of underground structure with the high-efficient discharge of infiltration of foundation ditch lateral wall, structural design is simple, practical.
