Description

Concealed automatic lifting and sewage interception maintenance system for the water inlet of the drainage project

technical field

The utility model relates to a sewage interception and maintenance technology in a waterlogging drainage project, in particular to a concealed automatic lifting and lowering pollution intercepting and maintenance system for a waterlogging drainage project which has special requirements on architectural landscapes and is suitable for a waterlogging drainage project with many floating objects during the waterlogging drainage period.

Background technique

For the inlets of drainage projects built in urban wetlands, parks, rivers and lakes, etc., usually higher requirements for landscape effects are required. The upper part of the building is realized, and the part of the building that is exposed to the water surface is rather abrupt, and it is difficult to coordinate with the original landscape on the water surface.

In addition, when the flood discharge flow and flow velocity are large, the water flow often carries a large amount of dirt and sediment, which can easily cause blockage and deposition of the water inlet. , The safety risk is relatively large when manual wading is used for cleaning.

Utility model content

The purpose of the utility model is to provide a hidden automatic lifting and blocking sewage maintenance system for the waterlogging drainage project water inlets with high landscape requirements such as urban wetlands, parks, rivers and lakes. On the one hand, the automatic control of pollution blocking, silt reduction and maintenance can be realized safely and reliably.

The purpose of the utility model is achieved through the following technical solutions: a hidden type automatic lifting and maintenance system for the water inlet of the drainage project, which mainly includes a shaft-type water inlet, a floating box-type gate, a vertical stainless steel trash rack, and a horizontal stainless steel trash barrier. Grid, control room, maintenance channel.

The shaft-type water inlet is the inlet for flood discharge, and the size is determined according to hydraulic calculation, followed by a drainage tunnel. The elevation of the top of the water inlet is generally set to be 0.5m to 1m lower than the normal water level, and no buildings are arranged on the upper part to ensure that the original landscape effect will not be affected during the non-drainage period.

The floating box gate is composed of a stainless steel floating box, a concrete slot, a hydraulic jacking mechanism and an equipment room. The concrete slot is located at the top of the shaft-type water inlet. Below the concrete slot is an equipment room with a ring-shaped reinforced concrete structure. The stainless steel floating box is arranged in the concrete slot. Top rod connection. The self-weight of the stainless steel floating box is set to be slightly larger than the buoyancy at the normal water level. During the maintenance period, the stainless steel floating box is raised to 0.5m above the normal water level by means of the hydraulic jacking mechanism located at the lower part of the stainless steel floating box. The hydraulic jacking mechanism at the lower part can jack up the stainless steel floating tank without providing a large thrust, which not only saves energy consumption, but also has high reliability. During the drainage period, the stainless steel floating box is raised to about 1m above the top elevation of the water inlet by the hydraulic jacking mechanism. At this time, the stainless steel floating box is equivalent to a sand barrier with adjustable height, which can greatly reduce the amount of sediment entering the drainage tunnel from the water inlet. Prevent the drainage tunnel from affecting the flow capacity due to siltation. The lower hydraulic push mechanism is arranged in a closed equipment room, which is isolated from the water surface and is not easy to rust.

In order to enhance the pollution blocking effect during the flood drainage period, the first pollution blocking facility can be arranged upstream of the river confluence entrance of urban wetlands, parks, rivers and lakes to filter out most of the floating objects. The vertical stainless steel trash rack is arranged on the top of the stainless steel floating box, and the height of the vertical stainless steel trash rack is raised to about 1m above the flood level during the drainage period. The vertical stainless steel trash rack and the horizontal trash rack are combined to strengthen the trash retention. A small amount of debris accumulated in the shaft-type water inlet can be cleaned up after the flood recedes. After two sewage blocking facilities, there are very few sundries that can enter the shaft-type water inlet and tunnel, which can ensure the smooth drainage of waterlogging during the flood period.

The control room can be arranged far away from the water inlet and on the shore where the landscape requirements are not high. During the flood season, personnel on duty in the control room can control the hydraulic jacking mechanism according to the water level to adjust the height of the stainless steel floating box and the vertical stainless steel trash rack to achieve the best effect of intercepting sewage and sand. During the maintenance period, the hydraulic jacking mechanism is controlled to raise the stainless steel floating tank to 0.5m above the normal water level, the water in the shaft is drained with a water pump, and the shaft-type water inlet is repaired.

The maintenance channel is a reinforced concrete structure buried in the ground, one end is connected with the equipment, and the other end serves as an entrance leading to the ground. The main function of the maintenance channel is for the staff to enter the equipment room from the outside to carry out daily maintenance and repair of the hydraulic jacking mechanism. The entrance of the maintenance channel can be arranged separately on the shore near the water inlet or in the control room.

The beneficial effects of the present utility model are:

1) There is no need to arrange buildings on the upper part of the water inlet, which does not affect the original water surface landscape effect and saves project investment;

2) During the drainage period, the floating box gate can also be used as a sand barrier, which greatly reduces the amount of sediment entering the drainage tunnel. The vertical stainless steel trash rack at the top of the stainless steel floating box and the horizontal stainless steel trash rack at the top of the shaft can be used as the second Road pollution blocking facilities to further intercept floating objects;

3) The gate adopts the floating box type, which reduces its own weight. The buoyancy of a part of the water can also be used when lifting during the maintenance and drainage periods, which reduces the load of the lower hydraulic jacking mechanism. Even if the floating box gate is deposited by sediment, the hydraulic The thrust provided by the jacking mechanism is also far less than the thrust required to lift the conventional gate;

4) The utility model realizes automatic control for maintenance and pollution blocking, and no manual wading is required during the drainage period, and the safety is guaranteed.
