Description

Submerged type penetrating beam structure of embedded tube bank of hydropower house Technical Field The invention relates to the field of underground buildings, in particular to a structure formed by crossing beam steel bars by embedded pipes in a floor slab. Background The underground powerhouse of the hydropower station is generally of a frame structure and mainly comprises beams, floors, upright posts and the like. The floor is generally provided with beams for supporting at intervals of a certain span, and the floor and the beams are integrally poured to form a flat top surface. According to the functional requirement, a plurality of embedded pipes are usually arranged between the floor slabs, and the embedded pipes are used for penetrating pipelines of various devices. Before concrete is poured, the embedded pipes are arranged in gaps among the floor slab steel bars and are arranged along the horizontal direction, when the embedded pipes pass through the steel bars of the beam, the longitudinal bars and the stirrups on the upper part of the beam are dense, and the embedded pipes are large in number and need to be grouped, so that the difficulty of the embedded pipes passing through the steel bars of the beam is increased. The conventional construction method of the embedded pipe penetrating beam is that each embedded pipe directly penetrates through gaps of reinforcing steel bars at the upper part of the beam along the horizontal direction, and when the reinforcing steel bars at the upper part of the beam are too dense, the condition that the embedded pipes cannot normally penetrate easily occurs. In actual construction, the embedded pipe is often forced to pass through the steel bars of the beam by bending and extruding the embedded pipe and prying the steel bars at the upper part of the beam. On the one hand, after the embedded pipe forcedly passes through the steel bars of the beam, the steel bars at the upper part of the beam are locally deformed and displaced, so that the concrete pouring at the part is difficult, the thickness of the protective layer at the top of the beam is easy to be reduced, the quality problem caused by the position deviation of the stressed steel bars is solved, and the construction quality of the beam is seriously influenced. On the other hand, the construction of the embedded pipe is difficult, the embedded pipe is easy to bend excessively after being deformed, the local cross section is reduced, even the pipe blockage occurs, the pipeline is penetrated in the embedded pipe in the later period, the number of the embedded pipes is large, and the risk of pipe blockage is high. The embedded pipe passes over the top of the beam steel bar, so that the steel bar of the beam is not disturbed, and the later pouring concrete is not influenced, but the top surface of the floor slab and the top surface of the beam are generally required to be flush, and the thickness of the floor slab is required to be increased, so that the construction cost is increased. Disclosure of Invention The invention provides a submerged penetrating beam structure of a pre-buried pipe row of a hydropower station factory building, which solves the problems that the construction of a pre-buried pipe penetrating beam in a floor is difficult and the construction quality is easy to influence. The embedded pipe row sinking type beam penetrating structure of the hydropower house comprises two steel bars of the horizontal floor slabs and steel bars of the beam, wherein the steel bars are positioned between the two floor slabs, the top surface of the floor slab and the top surface of the beam are positioned on the same horizontal plane, the embedded pipes are arranged in gaps of the steel bars of the floor slab and penetrate through the gaps of the steel bars of the beam, at least two embedded pipes are fixed side by side to form an embedded pipe row, the embedded pipe row is fixedly connected with the steel bars of the floor slab, each embedded pipe comprises two straight pipe sections positioned in the two floor slabs and a penetrating Liang Guanjie, the two straight pipe sections penetrate through the steel bars of the beam, the two straight pipe sections are respectively connected to two ends of the beam penetrating pipe sections, the beam penetrating pipe sections are sequentially divided into an upper straight pipe section, an inclined pipe section, a lower straight pipe section, an inclined pipe section and an upper straight pipe section, the height of the position of the lower straight pipe section is lower than the height of the steel bars positioned in the upper straight pipe section and penetrates through the gaps of the steel bars in the middle of the beam, an included angle formed by the inclined pipe section and the upper straight pipe section is an obtuse angle. In order to adjust the distance between two adjacent embedded pipes in the embedded pipe row, the embedded pipe row is better suitable for t
