Background
Along with the three-year action of upgrading and efficiency improvement of town sewage treatment and the improvement of the standards of rainwater drainage design in the reappearance period, the requirements for building and modifying town drainage pipelines are increasing day by day. Due to the requirements of urban construction, water treatment facilities are far away from the city center, drainage needs to be conveyed in a long distance, and part of drainage pipelines need to adopt a box culvert form. The construction of the drainage box culvert basically cannot realize one use and one standby, otherwise, the construction investment is huge. And the drainage box culvert is continuously operated after being put into operation, and certain difficulty is brought if the drainage box culvert needs to be dredged or overhauled.
In order to realize dredging or maintenance, the water transfer is usually carried out after the underwater temporary plugging in the box culvert is carried out at low flow, if the pressure box culvert needs a branch pump station to be matched with water stop, the operation process is complex, and the influence surface is large.
Disclosure of Invention
The invention aims to provide a drainage box culvert manhole which can overcome some defects in the prior art.
In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a drainage box culvert manhole, during its characterized in that drainage box culvert, every certain distance apart sets up one and examines and repair the well, establishes the picture peg floodgate slot in the examine and repair well, be equipped with the picture peg floodgate of dismantling with it complex in the picture peg floodgate slot, the picture peg floodgate entrance to a cave of establishing with picture peg floodgate complex is established at picture peg floodgate slot top box culvert top, establishes first pressure apron on the picture peg floodgate entrance to a cave, and the box culvert top around the slot still is equipped with the square entrance to a cave, establishes second pressure apron on the square entrance to a cave.
Furthermore, an access well is arranged every 500-2000 m in the drainage box culvert.
Furthermore, lifting hooks are arranged on the first pressure cover plate and the second pressure cover plate and used for lifting the cover plates.
Further, the width of the plug board gate opening is 500-1200 mm, the length of the plug board gate opening is matched with that of the plug board gate opening, and the length and the width of the square opening are both 1000-2000 mm.
Furthermore, a flange opening is arranged on the pressure cover plate, a detachable blind plate is arranged on the flange opening, the flange opening is plugged by the blind plate when the box culvert normally operates, and the pressure cover plate is opened when ventilation is needed.
The method for overhauling the drainage box culvert by using the drainage box culvert overhaul well is characterized by comprising the following steps of:
A. reducing the running water level of the pressure drainage box culvert to be below the ground elevation;
B. opening the second pressure cover plate 1, installing a water transfer pump and starting;
C. opening the first pressure cover plate 2 and inserting the flashboard 5;
D. overhauling the box culvert on the downstream water flow side of the spile gate, and taking out the spile gate 5 and the water transfer pump after the overhauling is finished;
E. and recovering the second pressure cover plate 1 and the first pressure cover plate 2, and recovering the normal operation of the box culvert.
Compared with the prior art, the invention has the following advantages and beneficial effects:
according to the technical scheme, underwater plugging is not needed in the arrangement of the inspection well, and the risk of water cut-off construction is greatly reduced. Meanwhile, the system can basically realize the operation without stopping water, does not need a branch pump station to stop water, reduces the operation complexity and influence in the dredging or overhauling process, and has practical application value.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
The invention relates to a drainage box culvert manhole, which is characterized in that:
every 500~2000m of drainage box culvert sets up an inspection shaft, establishes the picture peg floodgate slot 6 in the inspection shaft, be equipped with the detachable picture peg floodgate 5 of complex with it in the picture peg floodgate slot 6, the picture peg floodgate entrance to a cave of establishing with picture peg floodgate complex is established at box culvert top above the picture peg floodgate slot, establishes first pressure apron 2 on the picture peg floodgate entrance to a cave, and the box culvert top around the slot still is equipped with the square entrance to a cave, establishes second pressure apron 1 on the square entrance to a cave.
The use method of the invention comprises the following steps:
A. reducing the running water level of the pressure drainage box culvert to be below the ground elevation;
