Description
Technical Field
The utility model relates to a hydraulic and hydroelectric engineering technical field, concretely relates to catch basin structure suitable for steep rock matter side slope.
Background
The intercepting drain on the steep mountain is difficult to excavate in the work progress, and large-scale construction machinery is difficult to expand, and especially the horizontal distance length overlength of intercepting drain bottom plate starting point and side slope face makes the back slope of intercepting drain too high, has increased the excavation degree of difficulty of intercepting drain again like this, but if cancel the intercepting drain will bring certain potential safety hazard for excavating the side slope. Therefore, the reasonable arrangement of the intercepting drain structure is very important. In order to avoid excessive excavation of the intercepting drain, domestic and foreign professionals have made relevant researches on the intercepting drain, for example, in a rock slope intercepting drain (CN 206655190U), in order to avoid excessive excavation of a mountain caused by the excavation of the intercepting drain, the intercepting drain is made to be outside of a mountain slope surface, so that the excavation of the intercepting drain on the side slope is avoided, and certain hidden dangers exist, for example: the whole structure of the intercepting ditch is positioned outside the slope surface of the hillside, the backfilled stone slag is positioned between the slope surface and the concrete retaining wall, the surface of the backfilled stone slag is coated with mortar, and no steel bar is needed. The design is durable very poor like this, and during the torrential rain, rainwater accessible mortar is wiped the seepage and is backfilled in the stone sediment, and the stone sediment is very easily saturated, and gliding force increases, and the concrete barricade only relies on the dowel to be connected with the rock, is difficult to resist the stone sediment gliding force of increase, and there is the potential safety hazard in the catch basin structure.
Therefore, when the intercepting drain is designed, the excessive excavation of a steep rock slope needs to be avoided, and the bottom of the intercepting drain is required to be located on the rock slope, so that the structure is stable. The current research still has shortcomings.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a catch basin structure suitable for steep rock matter side slope, the utility model discloses the excessive excavation of rock matter side slope when both can having avoided building the catch basin can make the catch basin bottom plate sit on the basement rock completely again, increases the stability and the security of catch basin structure.
Therefore, the utility model adopts the following technical scheme: a groove is dug on the rock slope, a catch drain is arranged in the groove, a bottom plate of the catch drain is tightly attached to an excavation plane, a side elevation of the inner side wall of the catch drain is tightly attached to an excavation slope surface, and the outer side wall of the catch drain is vertically arranged on the bottom plate.
Further: and the bottom plate of the intercepting ditch is connected with the lower part rock through a dowel.
Further: the excavation slope ratio of the excavation slope surface is 1: 0.5.
Further: the inner side of the upper surface of the intercepting ditch is provided with a surface layer rib, and the surface layer rib consists of a main stressed steel bar and a construction steel bar.
Further: the main stressed steel bar is closer to the upper surface of the intercepting drain than the structural steel bar.
Further: the bottom plate of the intercepting drain is completely seated on the bedrock of the steep rock slope.
Further: the outer edge of the outer side wall is arranged at the intersection of the groove and the original terrain line.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses dig on the rock matter side slope and establish the slot, for traditional catch basin, set up the downstream side wall in the outside of the original topography line of rock matter side slope, the excessive excavation of rock matter side slope when can avoiding building the catch basin reduces the excavation volume, reduces the construction degree of difficulty. Further, the utility model discloses the intercepting ditch bottom plate is located on the basement rock completely, does not use materials such as backfill stone sediment, can increase the stability and the security of intercepting ditch structure like this.
