Description
Technical field
The utility model relates to a kind of local steel lining structure in front and back of diversion tunnel gate slot.Be applicable to the gate slot protection of carrying the diversion tunnel engineering under erratic boulder and the more situation of bed load in the Hydraulic and Hydro-Power Engineering in big flow, high flow rate, the current secretly.
Background technology
Diversion tunnel is as extensively adopting in the numerous at home and abroad Hydraulic and Hydro-Power Engineerings of a kind of main earial drainage building of engineering construction phase.Diversion tunnel need carry out shutoff before reservoir filling, therefore gate slot and shutoff gate need be set.Often there are big, the characteristics such as flow velocity is high, carry a large amount of erratic boulders in the current secretly, bed load is more of flow in flood season in Hydraulic and Hydro-Power Engineering on some great rivers.Because the gate slot position of diversion tunnel often current is relatively more disorderly, very easily produce cavitation erosion, and often suffer the wearing and tearing of erratic boulder bump and bed load, very serious to the destroying concrete structure before and after the gate slot; Jeopardize structural safety, what in running, have can't overhaul, and because the distortion of gate slot; Increased the difficulty of time lock greatly; Very likely cause lock failure down, gently then postpone the reservoir filling time, influence generating duration and total duration of engineering; And then influence the project income, heavy then jeopardize engineering safety.So, study suitable diversion tunnel gate slot front and back structural defence measure and just become very necessary and urgent.
Summary of the invention
The technical problem that the utility model will solve is: a kind of local steel lining structure in front and back of diversion tunnel gate slot is provided, is intended to reduce runtime gate slot and front and back structural damage, improve lock success fraction down, reduce the potential safety hazard and the uncertain factor of engineering.
The technical scheme that the utility model adopted is: the local steel lining structure in the front and back of diversion tunnel gate slot; Be furnished with gate slot on the section concrete structure of gate hole; It is characterized in that: steel lining before the upstream side of said gate slot is arranged; The downstream cloth postpone steel lining of gate slot, preceding steel lining all is linked to be integral body through dowel and concrete structure with the back steel lining.
Metal construction embedded part in the said gate slot connects into integral body through welding and said preceding steel lining and back steel lining.
Steel lining has included base plate steel lining assembly and abutment wall steel lining assembly with the back steel lining before said.
Said base plate steel lining assembly is welded into an integral body by base plate steel plate, the steel plate of putting more energy into, stiffener angle and dowel; Put more energy into steel plate and stiffener angle is welded on to square crossing on the base plate steel plate in length and breadth; The dowel that is welded on the stiffener angle stretches in the concrete structure; Have the reservation grout hole on the base plate steel plate, have on the steel plate of putting more energy into and starch the hole.
Said abutment wall steel lining assembly is welded into an integral body by abutment wall steel plate, the steel plate of putting more energy into, stiffener angle and dowel; Put more energy into steel plate and stiffener angle is welded on to square crossing on the abutment wall steel plate in length and breadth; The dowel that is welded on the stiffener angle stretches in the concrete structure; Put more energy into to have on the steel plate and starch the hole.
The beneficial effect of the utility model is: the utility model all adopts the steel lining protection in the front and back of gate slot, has protected the structural integrity of gate slot effectively, improves lock success fraction down greatly, reduces the potential safety hazard and the uncertain factor of engineering.

The specific embodiment
Like Fig. 1, shown in Figure 2, present embodiment is the gate hole section concrete structure 4 that is furnished with gate slot 1.This example is steel lining 2 before the upstream side of gate slot 1 is arranged; The cloth postpone steel lining 3 in the downstream of gate slot 1, said preceding steel lining 2 has included base plate steel lining assembly (being used to protect the base plate of gate slot front and back) and abutment wall steel lining assembly (being used to protect the abutment wall of gate slot front and back) with back steel lining 3.
Like Fig. 3, Fig. 4, shown in Figure 5, said base plate steel lining assembly is welded into an integral body by base plate steel plate 9, the steel plate 5 of putting more energy into, stiffener angle 6 and dowel 7.The steel plate 5 of putting more energy into is welded on the base plate steel plate 9 to square crossing with stiffener angle 6 in length and breadth, and the steel plate 5 of putting more energy into plays the effect of strengthening rigidity with stiffener angle 6, and the height of the steel plate 5 of putting more energy into equates with the width of angle steel.The diameter of dowel 7 is Ф 22; Long L=1000mm; Density with 1500 * 500mm is welded on the stiffener angle 6; Dowel inserts in the base plate (comprising the base plate of gate slot front and the base plate of gate slot back) of concrete structure 4 during concreting, makes base plate steel lining assembly and concrete structure 4 be linked to be integral body.Have on the base plate steel plate 9 and reserve grout hole 9-1, the diameter of grout hole is Ф 60mm, offers a grout hole on the every lattice base plate that is formed by put more energy into steel plate 5 and stiffener angle 6.Simultaneously on the steel plate 5 of putting more energy into, have between two angle steel and starch hole 5-1, the diameter of starching the hole thoroughly is Ф 120mm.
