Description

A removable maintenance gate

technical field

The invention relates to a water retaining facility, in particular to a detachable maintenance gate, which is suitable for solving the maintenance water blocking problem of a large-span working gate such as a bottom shaft-driven steel gate.

Background technique

In view of the requirements of the surrounding landscape or navigation of the river, with the improvement of hydraulic steel structure design and manufacturing technology, many sluice gates will choose single-hole large-span gates as working gates. For example, the large-span bottom shaft drives the steel gate, which is the type of large-span sluice working gate that is widely used at present. Due to landscape or navigation reasons, no permanent structures are allowed across the entire river, so the maintenance of the water retaining facilities must be temporary. Up to now, there is no temporary water retaining facility with low cost and easy operation required for the maintenance of large-span working gates. Therefore, the maintenance of large-span bottom shaft-driven steel gates is mostly performed by divers underwater, which is difficult and dangerous. High, extremely inefficient, expensive, and limited maintenance programs achievable.

There are also individual projects that use floating doors as maintenance gates regardless of the cost. Its main flaws are:

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

(2) It is extremely inconvenient to use: the floating door is towed from the storage place to the vicinity of the access door slot of the sluice by the barge, the floating door is pulled towards and close to the access door groove, and the floating door is filled with water to sink the floating door to the bottom sill of the door groove , use a temporary water pump to drain the water in the lock chamber between the two floating doors. After the maintenance of the working gate is completed, the above process is reversed to haul the floating gate to the storage dock.

(3) High maintenance costs: The anti-corrosion maintenance of large floating doors needs to be carried out in the dock, so it needs to be towed to the nearest shipyard for anti-corrosion and other maintenance measures. The larger the scale of the floating door, the larger the dock required, the maintenance conditions are difficult to meet, and the maintenance cost is high.

SUMMARY OF THE INVENTION

In order to solve the problem that the prior art maintenance gate type is difficult to meet the maintenance water blocking requirements of large-span working gates, especially large-span bottom-shaft driven steel gates, the present invention provides a removable maintenance gate to solve problems such as bottom-shaft driven steel gates Water retaining problems during maintenance and repair of large-span working gates. Under the condition of effective water blocking, the working gate can be repaired and maintained safely, efficiently, comprehensively and thoroughly.

The invention is based on the principle of easy assembly and easy disassembly, and adopts the measures of section sealing, sealing and sleeve connection between sections, forming cofferdams in sections, and setting upright columns inside to fix each section, so as to set up a solid block across the river surface. water facility.

The technical scheme adopted by the present invention to solve the technical problem is as follows: a detachable maintenance gate, including a door leaf, a door slot, a column and a connecting member, the door leaf and the column are fastened and connected by the connecting member, and the column and the column are embedded in The column foundation in the door slot is fastened and connected, and a water stop is set between the door leaf and the door slot to achieve a good leak-proof effect. The door leaf is composed of a plurality of water retaining units connected to each other, and adjacent water retaining units can be sleeved together. Reliable water stop devices are provided between the water retaining units of each section, the bottom of the water retaining unit, the water retaining unit of the side section and the gate wall, that is, there is an inter-section water retaining device between the water retaining units of each section, and the bottom of the water retaining unit is provided with a water retaining device. Bottom water stop, there is a floating water stop between the side water retaining unit and the gate wall, so as to achieve a good water stop effect. The door slot is pre-buried with the water stop seat plate and the column foundation, which ensures the continuity of the water stop and the firmness of the connection between the column and the foundation. The connecting member consists of two welded steel structural members, one of which is connected to the longitudinal beam of the water retaining unit by high-strength bolts from top to bottom, and the other is connected to the flange plate of the column by high-strength bolts from top to bottom. The connection parts of the steel members are provided with waist-shaped holes and connected by high-strength bolts, so as to realize the error adjustment and firm connection between the door leaf and the column, so that the water pressure is transmitted to the column through the door leaf and the connecting member, and then by the column. Give the concrete foundation to ensure the safety of the water retention of the entire access gate.

The beneficial effects of the invention are as follows: the mechanical model is clear, which is convenient for design; the door-shaped structure is simple and convenient for manufacture; The water retaining height is determined according to the actual maintenance water level of the project), which is convenient for storage; there are no special requirements for the maintenance site and no complex components, so the maintenance is simple and easy to implement and the cost is low.
