Description

Detachable maintenance gate

Technical Field

The utility model relates to a manger plate facility, concretely relates to dismantled and assembled maintenance gate is applicable to the maintenance manger plate difficult problem of solving large-span work gate such as bottom shaft drive steel gate.

Background

In view of the requirements of the landscape around the river channel or navigation, along with the improvement of the design and manufacture technology of the hydraulic steel structure, a plurality of water gates can select a single-hole large-span gate as a working gate. For example, the long-span bottom shaft drives a steel gate, which is a widely adopted long-span water gate working gate type at present. Maintenance of water retaining facilities must be temporary because permanent structures are not allowed across the entire river surface for landscaping or navigation reasons. At present, no temporary water retaining facility which is low in manufacturing cost and easy to operate and is required for overhauling the large-span working gate exists, so that most of overhauling of the large-span bottom shaft driving steel gate is performed by underwater operation of divers, and the problems of high difficulty, high danger, extremely low efficiency, high cost and limited achievable overhauling and maintenance projects exist.

And the cost is also ignored in individual projects, and a floating gate is adopted as an inspection gate. The main defects are as follows:

(1) the cost is high: the cost of the floating gate used as a working gate maintenance water retaining facility is even higher than that of the working gate;

(2) it is extremely inconvenient to use: the floating gate is towed to the position near the sluice access gate groove from the storage ground by a barge, the floating gate is pulled to and closely attached to the access gate groove, water is filled into the floating gate to enable the floating gate to sink to the bottom sill of the sluice groove, and a temporary water pump is used for pumping out water in the sluice chamber between two floating gates. And after the maintenance of the working gate is finished, the floating gate is hauled to the stored wharf by reversely executing the flow.

(3) The maintenance cost is high: the anticorrosion maintenance of the large floating door needs to be carried out in a dock, so that the large floating door needs to be hauled to a shipyard closest to the shipyard to carry out maintenance measures such as anticorrosion and the like. The larger the floating door size is, the larger the required dock is, the more difficult the maintenance conditions are to be met, and the maintenance cost is high.

The door leaf is formed by connecting a plurality of sections of water retaining units, and adjacent sections of water retaining units can be sleeved together. Reliable water stopping devices are arranged among the water stopping units, at the bottom of the water stopping units, at the side sections of the water stopping units and the gate wall, namely, water stopping among the sections is arranged among the water stopping units, bottom water stopping is arranged at the bottom of the water stopping units, and floating water stopping is arranged between the side sections of the water stopping units and the gate wall, so that a good water stopping effect is realized. The door slot is pre-buried with stagnant water bedplate and stand basis, has guaranteed the fastness of the continuity of stagnant water and stand and basic connection. The connecting component comprises two welded steel structural members, one of the two welded steel structural members is connected with the longitudinal beam of the water retaining unit by high-strength bolts from top to bottom, the other welded steel structural member is connected with the flange plate of the upright column by high-strength bolts from top to bottom, the connecting part of the two steel structural members is provided with a waist-shaped hole and is connected by the high-strength bolts, so that error adjustment and firm connection between the door leaf and the upright column are realized, water pressure is transmitted to the upright column through the door leaf and the connecting component, and then the upright column is transmitted to the concrete foundation, and the water retaining safety of the whole maintenance gate is ensured.

The utility model has the advantages that: the mechanical model is clear and convenient to design; the door-shaped structure is simple and convenient to manufacture; the manufacturing cost is low; the operation is simple, safe and efficient under the anhydrous environment; the single-piece component has small size (the length of a single section can be controlled within 4m, the water retaining height is determined according to the actual overhaul water level of the project), and the single-piece component is convenient to store; no special requirements on the overhaul and maintenance site and no complex components, so the overhaul and maintenance are simple and easy to implement and the cost is low.
