Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship lock construction, in particular to a cast-formed ship lock water delivery gallery diversion pier. Background Art
[0002] The operation of the ship lock is very busy, and a large number of ships pass through every day, which requires multiple water inlet and outlet operations. During the water inlet and outlet process, the water flow has a large impact on the corridor, which is destructive to a certain extent, especially when the high water level valve is just opened and closed, there will be a water hammer effect. At the sharp bend of the water flow in the water delivery corridor, vortices are easily formed to produce cavitation. This cavitation has a strong vibration effect on the structures in the water delivery corridor. Cavitation and water hammer will have a destructive effect on the defective parts of the concrete surface. In order to reduce the damage caused by cavitation and water hammer caused by the vortex formed at the sharp bend of the water flow in the ship lock water delivery corridor to the defective parts of the concrete surface, a diversion pier is set at the sharp bend of the water flow in the ship lock water delivery corridor, and a steel protective surface is added to the outer surface of the diversion pier built of reinforced concrete to protect the ship lock water delivery corridor and reduce the destructive effect of cavitation caused by the turbulent water flow on the water delivery corridor structure.
[0003] For the above reasons, the construction quality of the diversion pier is very important. The conventional diversion pier casting construction process is usually to first cast the diversion pier steel armor according to the design shape and size of the diversion pier, and then pour concrete into the diversion pier steel armor that has been tied with steel bars and fixed. Since the lower end of the diversion pier steel armor has an outward-inclined lower chamfer, the flowing concrete will produce a large buoyancy on the inner slope of the lower chamfer, which will cause the streamlined diversion pier's overall steel armor to float, causing leakage at the bottom of the steel armor, and even causing the overall steel armor of the diversion pier to shift. When problems are found during the pouring of concrete, it is necessary to stop pouring concrete or even remove the concrete inside the steel armor, and re-reinforce the overall steel armor of the diversion pier, which affects the construction progress and wastes a lot of concrete.
[0004] The conventional solution is to fix the steel armor of the diversion pier on the ground, use an impact drill to drill multiple vertical downward holes in the concrete ground around the steel armor of the diversion pier, and then install the gaskets with expansion bolts to these holes. One end of the gasket is welded to the bottom of the overall steel armor of the diversion pier, and then the overall steel armor of the diversion pier is fixed to the concrete ground. Since the expansion bolt screw rod is an indirect force to fix the steel armor, the buoyancy on the steel armor acts on the gasket and the expansion bolt screw rod, which will produce an upward pulling force and bending moment on the expansion bolt screw rod. If the size of the expansion bolt is too small or too few, the buoyancy of the steel armor will pull the expansion bolt, which will cause leakage at the bottom of the steel armor. Utility Model Content
[0005] In order to solve the above-mentioned problems of the prior art, the utility model provides a cast-formed diversion pier for a water conveyance gallery of a ship lock, which can resist the buoyancy generated by the bottom of the steel protective surface of the diversion pier, has good anti-floating effect, and can well fix the steel protective surface of the diversion pier on the concrete ground.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cast-formed diversion pier for a water conveyance gallery of a ship lock, comprising a protective surface matching the shape of the diversion pier, and a fixing rod arranged at the lower end of the protective surface, wherein the axial direction of the fixing rod forms an angle greater than 0 degrees and less than 90 degrees with the longitudinal direction of the protective surface, and a plurality of the fixing rods are arranged.
[0007] With the above structural design, fixing rods are driven into the concrete ground around the diversion pier face, and then the face is connected to the fixing rods, and then concrete is poured into the face. Since the buoyancy of the face is vertically upward, and the fixing rods around the face are inclined, and multiple fixing rods restrict the face at the same time, the vertical upward buoyancy received by the face cannot pull the inclined fixing rods out of the concrete, so the fixing effect is very good.
[0008] Preferably, the protective surface includes an outer protective surface, an inner protective surface arranged on the inner side of the outer protective surface, and a support rod arranged between the outer protective surface and the inner protective surface. Both ends of the outer protective surface and the inner protective surface are provided with outwardly folded chamfers, and the fixing rod is arranged at the lower end of the outer protective surface.
[0009] By adopting the above structural design, concrete can be poured in sequence. First, it is poured between the inner and outer protective surfaces to form a stable supporting structure, and then poured between the inner protective surfaces. This not only reduces the buoyancy of the concrete on the protective surfaces, but also prevents the deformation of the formed diversion pier and increases the stability of the diversion pier.
[0010] Preferably, the fixing rod is covered with external threads.
[0011] With the above structural design, when the fixing rod is driven into the concrete floor, the fixing rod and the concrete inclined hole wall are tightly matched, which will generate greater friction and further increase the anti-floating effect.
[0012] Preferably, a plurality of stabilizing rods are fixedly connected to the fixing rod, and the axial direction of the stabilizing rod forms an acute angle with the axial direction of the fixing rod.
[0013] With the above structural design, fixing rods are embedded in the concrete floor. The fixing rods will form a root-shaped cementing body on the concrete floor, which makes the fixing rods have greater pull-out resistance. After the fixing rods are connected to the outer protective surface, the protective surface is further prevented from floating.
[0014] Preferably, the lower end of the outer protective surface is fixedly connected to a plurality of support plates, through holes matching the fixing rods are provided on the support plates, and the upper ends of the fixing rods are connected to fixing nuts through threads.
[0015] With the above structural design, the fixing rod is connected to the outer protective surface through a nut, and the connection is quick, simple and convenient.
[0016] Preferably, the inclination directions of adjacent fixing rods are opposite.
[0017] The above structural design can prevent the fixing rods from tilting in the same direction, and prevent the protective surface from being subjected to lateral external forces, causing the protective surface to deviate in the left and right directions.
[0018] Compared with the prior art, the beneficial effects of the utility model are:
[0019] 1) Good fixing effect and anti-floating effect. Since the buoyancy of the protective surface is vertically upward, and the fixing rods around the protective surface are inclined, and multiple fixing rods restrict the protective surface at the same time, the vertical upward buoyancy of the protective surface cannot pull the inclined fixing rods out of the concrete.
[0020] 2) Concrete can be poured into the device in sequence, first pouring between the inner and outer protective surfaces to form a stable supporting structure, and then pouring between the inner protective surfaces. This not only reduces the buoyancy of the concrete on the protective surfaces, but also prevents the deformation of the formed diversion pier and increases the stability of the diversion pier.
[0021] 3) Save time and effort. The protective cover is quick and convenient to install, reducing the workload of staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The utility model provides a technical solution: a cast-formed diversion pier for a water delivery gallery of a ship lock, comprising a protective surface 1 matching the shape of the diversion pier, and a fixing rod 2 arranged at the lower end of the protective surface 1, wherein the axis direction of the fixing rod 2 forms an angle greater than 0 degrees and less than 90 degrees with the longitudinal direction of the protective surface 1, and a plurality of fixing rods 2 are provided. The inclination angle of the fixing rods ranges from 20 degrees to 40 degrees.
[0032] Generally speaking, the front and rear ends of the diversion pier are cylindrical diversion columns, and the middle part of the diversion pier is an arc structure connecting the two diversion columns. The width of the middle part of the diversion pier is roughly equal to the width of the diversion column. The protective surface is made of steel or other alloy materials to protect the entire diversion pier, in order to reduce the damage to the defective parts of the concrete surface caused by cavitation and water hammer caused by the vortex formed at the sharp turn of the water flow in the lock water delivery gallery. The protective surface 1 is made according to the shape of the diversion pier, and the protective surface 1 is also used as a mold for casting the diversion pier.
[0033] The protective surface 1 includes an outer protective surface 11, an inner protective surface 12 arranged on the inner side of the outer protective surface 11, and a support rod 13 arranged between the outer protective surface 11 and the inner protective surface 12. Both ends of the outer protective surface 11 and the inner protective surface 12 are provided with chamfers folded outward, and the fixing rod 2 is arranged at the lower end of the outer protective surface 11.
[0034] The inclination directions of adjacent fixing rods 2 are opposite.
[0035] When the device is in use, the staff first uses an impact drill to drill a plurality of inclined holes on the concrete floor, and then the staff drives the fixing rod 2 into the inclined hole, the diameter of the middle and upper part of the fixing rod 2 is slightly larger than the diameter of the inclined hole, and the diameter of the lower part of the fixing rod 2 is slightly smaller than the diameter of the inclined hole, and then the staff welds the outer protective surface 11 to the fixing rod, fixes the steel bars in the inner protective surface 12, and finally the staff pours concrete in sequence, first pouring between the inner protective surface 11 and the outer protective surface 12, and after forming a stable supporting structure, pouring into the inner protective surface 12, which not only reduces the buoyancy of the concrete on the protective surface, but also prevents the deformation of the formed diversion pier and increases the stability of the diversion pier.
[0036] Embodiment 2:
[0037] like Figure 5 As shown, the second embodiment is modified relative to the first embodiment. The fixing rod 2 is covered with external threads and is made of short threaded steel bars. The other parts are in accordance with the second embodiment.
[0038] When the device is in use, the staff first uses an impact drill to drill a plurality of inclined holes on the concrete floor, and then the staff installs the fixing rod 2 into the inclined hole, and then the staff welds the outer protective surface 11 to the fixing rod, fixes the steel bars in the inner protective surface 12, and finally the staff pours concrete in sequence, first pouring between the inner protective surface 11 and the outer protective surface 12, and then pouring into the inner protective surface 12 after forming a stable supporting structure. This not only reduces the buoyancy of the concrete on the protective surface, but also prevents the deformation of the formed diversion pier and increases the stability of the diversion pier.
[0039] Embodiment three:
[0040] like Figure 6 As shown, the third embodiment is modified relative to the first embodiment. A plurality of stabilizing rods 21 are fixedly connected to the fixing rod 2. The axial direction of the stabilizing rod 21 forms an acute angle with the axial direction of the fixing rod 2. The other parts are in accordance with the second embodiment.
[0041] When the device is in use, the staff first embeds the fixing rod 2 before the concrete floor is poured. The stabilizing rod 21 will form a root-shaped cementing body on the concrete floor, so that the fixing rod 2 has a greater pull-out resistance. Then the staff welds the outer protective surface 11 to the fixing rod, fixes the steel bars in the inner protective surface 12, and finally pours the concrete in sequence, first pouring between the inner protective surface 11 and the outer protective surface 12 to form a stable supporting structure, and then pouring into the inner protective surface 12. This not only reduces the buoyancy of the concrete on the protective surface, but also prevents the deformation of the formed diversion pier and increases the stability of the diversion pier.
[0042] Embodiment 4:
[0043] like Figure 7 As shown, the fourth embodiment is modified relative to the second embodiment. The lower end of the outer protective surface 11 is fixedly connected to a plurality of support plates 3, the support plates 3 are provided with through holes matching the fixing rods 2, and the upper ends of the fixing rods 2 are connected to the fixing nuts 4 by threads.
[0044] When the device is in use, the staff first uses an impact drill to drill a plurality of inclined holes on the concrete floor, and then the staff places the protective surface 1 on the concrete floor, the through holes on the support plate 3 correspond to the inclined holes, and then the staff passes the fixing rod 2 through the support plate 3 and then installs it into the inclined hole. The fixing rod 2 can be made of threaded steel bars, or the fixing rod 2 uses bolts, and then the staff installs nuts on the upper end of the fixing rod 2. Finally, the staff pours concrete in sequence, first pouring between the inner protective surface 11 and the outer protective surface 12, and after forming a stable supporting structure, pouring into the inner protective surface 12. This not only reduces the buoyancy of the concrete on the protective surface, but also prevents the deformation of the formed diversion pier and increases the stability of the diversion pier.

The lower end of the outer protective surface 11 is fixedly connected to a plurality of support plates 3, the support plates 3 are provided with through holes matching the fixing rods 2, and the upper ends of the fixing rods 2 are connected to the fixing nuts 4 through threads.
[0047] When the device is in use, the staff first embeds the fixing rod 2 before the concrete floor is poured. The stabilizing rod 21 will form a root-shaped cementing body on the concrete floor, so that the fixing rod 2 has a greater pull-out resistance. Then the staff will correspondingly sleeve the support plate 3 on the upper end of the fixing rod 2, and then install the nut. In order to facilitate the fixing rod 2 to pass through the support plate 3, the through hole is a long hole, and the steel bar is fixed in the inner protective surface 12. Finally, the staff pours concrete in sequence, first pouring between the inner protective surface 11 and the outer protective surface 12, and then pouring into the inner protective surface 12 after forming a stable supporting structure. This not only reduces the buoyancy of the concrete on the protective surface, but also prevents the deformation of the formed diversion pier and increases the stability of the diversion pier.
