Technical Field

The invention relates to the technical field of barrages or weirs of hydraulic engineering, in particular to an integrated steel gate.

Background

At present, the types of the water retaining gates adopted on various small water gates of projects such as long-distance water transfer (transportation), farmland water conservancy, reservoirs, impounded water and the like mainly comprise two types, namely a sliding plane gate and a fixed wheel gate. The plane gate can be opened and closed along the gate slot, and has plane water-retaining panel, the fixed wheel gate is a plane gate with wheels as supporting walking parts on the edge beam, and the sliding gate is a plane gate with slide or slide blocks as supporting walking parts on the edge beam. The two types of gates can be divided into a down-hole type gate and an exposed top type gate from the form of a gate opening, and are divided into a one-way water retaining type gate and a two-way water retaining type gate from the water retaining direction. The sliding plane gate can be divided into a sliding steel gate and a cast iron gate according to different materials, and the fixed wheel gate can be divided into a cantilever wheel type plane steel gate and a simple support wheel type plane steel gate from different types of supporting rollers. The structure of the sliding gate and the fixed wheel gate mainly comprises a gate leaf, a water stopping device, a supporting device and a gate embedded part; the water stopping device generally adopts rubber or rubber-plastic composite water stopping, belongs to a flexible water stopping device, and is pressed tightly by water pressure to stop water by prepressing for a certain amount to cling to the water stopping seat plate to seal gaps around the door leaf so as to stop water leakage; the gate slot is mainly a gate supporting and guiding device formed by in-situ pouring of each embedded part and secondary concrete; the gate embedded part transfers the load born by the gate to concrete and mainly comprises a main steel rail, a return rail, side rails, a sill and a door head. The embedded parts are installed and firmly connected with the exposed anchor bars embedded in the first-stage concrete, and then the second-stage concrete is poured. The main rail, the reverse rail and the side rail are all arranged on the door groove, and the water stop seat plate is usually welded on the main rail or the reverse rail and the door head by adopting a stainless steel plate. The dew top gate has no lintel. Cast iron gates are machined from a single casting piece or from multiple castings after machining. The gate embedded part is an assembly part of a main rail, a reverse rail, a side rail or a limiting block, a bottom sill and a door head which are processed by cast iron, the gate and the embedded part assembly part are integrally ground to reach certain precision and then have a certain water stopping function, and the gate embedded part belongs to a rigid water stopping device and mainly depends on the action of water pressure or the combined action of the water pressure and external mechanical force to force a water stopping plane to close and stop water. The main drawbacks of the above-mentioned gate type are as follows:

1. the main drawbacks of cast iron gates are:

1) the cast iron gate has not been formed into the specification of design, manufacture, installation and acceptance of the hydraulic engineering cast iron gate in the water conservancy industry since the advent of the cast iron gate, and no standard exists no matter the design or the manufacture quality is consistent, so that the cast iron gate forms the current situations of numerous domestic manufacturers, incapability of uniformly controlling the quality and frequent engineering accidents;

2) the size of the gate water retaining orifice is limited, the water retaining height is low, namely limited by materials and processes, the width of the cast iron gate is within 3m, the door plate is segmented when the size is large, and the maximum water retaining height of the cast iron gate with various specifications is limited within 6 m;

3) the manufacturing process is complex, the precision requirement is high, the material defects and the like are difficult to achieve the due functions of the gate, the water stopping effect is poor due to serious water leakage, accidents and even disasters occur frequently due to stress deformation and corrosion of the gate or the door frame, and the gate or the door frame is stuck and stuck due to the water pressure damage of the gate or the door frame;

4) because of rigid water stopping, the reverse water stopping level cannot exceed the height of the door and the water leakage is serious, and the requirement of bidirectional water stopping cannot be really realized;

5) the manufacturing pollution is serious, the cast iron gate can not ensure normal production and the product quality can not be ensured under the influence of national environmental protection laws, regulations and policies at present.

2. The main drawbacks of the steel plane gates:

1) the height of a door leaf beam system and the structural size of an edge beam of the fixed wheel gate and the sliding gate need to be calculated and determined according to factors such as the size of an orifice, the type of the orifice (exposed top type and down-the-hole type), the water blocking height, bidirectional water blocking or unidirectional water blocking, the supporting type (a slide block, a cantilever wheel and a simple support wheel) and the like; the embedded parts are all steel structure workpieces or cast steel workpieces welded by steel profiles, the section size and the structure size of the embedded parts are determined according to the factors, and the embedded parts are fixed, connected and assembled, and then poured concrete is formed to form facilities required by the functions of the gate, such as supporting, lifting guiding, water stopping and the like. Under the circumstances, the medium and small-sized plane steel gates can not form series products so far, the gates of almost every medium and small-sized water gates need professional technicians to do a large amount of non-standard product design work, gate manufacturers manufacture the gates according to non-standard product design drawings, and installation units install the gates according to the design.

2) The fixed wheel gate and the sliding steel gate have relatively more complex structures. The gate embedded parts usually comprise independent main rails, return rails, side rails, sill, lintel, auxiliary rails and the like, the material consumption is large, the manufacturing and installation engineering quantity is large, the procedures of measurement paying-off, inspection, welding, assembly and the like are more, and the installation precision is low and is not easy to control, the construction period is long and the engineering cost is high due to poor visibility conditions in a gate hole.

The main line of water delivery engineering of a certain hydraulic engineering Shandong segment is about 487km from the Korea canal to the Texas big-tun reservoir, the main line of the Jiaodong segment is about 704km from the east Pinghu to the Mishan reservoir of the Weihai, and the water delivery is built in 2014. Along the line, the water distribution gate, the check gate, the inverted siphon, the culvert gate and other buildings are provided with thousands of seats. Wherein, the total number of the small culvert gates adopting cast iron gates is more than 500; 7 pump stations and 3 regulation and storage reservoirs. In order to solve the problems of water quality guarantee and the like of water delivery engineering, a cast iron gate of about 200 small culverts at the chatting section of the engineering is required to be transformed so as to solve the problems that the original cast iron gate cannot be blocked by reverse water stop, the gate leaf cannot be normally opened and closed due to deformation and corrosion, and the like at intervals.
