Taking the project specifically designed and constructed by the applicant as an example, namely a black dragon beach scenic area sewage main pipe project, a drop well of the project is of an ultra-large and ultra-deep type, the inner diameter of the well reaches 6m, and the depth exceeds 18m, as shown in fig. 1-4, the main structure of the drop well body is still constructed according to the existing construction design standard, for example, the wall of the drop well body 1 is communicated with sewage pipelines 2 and a mud sinking well 3 from all directions, the bottom of the drop well body 1 is constructed with a sewage pipeline 4, a tunnel 5 and the like, the difference is that an inspection ventilation opening 6 with the size of 4.5 × 1.5.5 m is arranged at the top of the drop well body 1, an anti-overturn railing 7 is additionally arranged at the top of the inspection ventilation opening 6, the inspection ventilation opening 6 is sealed by a grid cover plate 8 and a steel cover plate 9, a drop net 10 is arranged at the lower part of the grid cover plate 8, a protection ladder 11 is arranged downwards along the wall of the ventilation opening 6, the protection ladder 11 extends to the wall of the drop well body 1 until the wall of the drop well body 1, then a spiral drop canal 12 is constructed with a drop canal 12, the step is communicated with a sewage branch pipe 13 of the drop cage 12.5, and the sewage pipeline of the drop well wall of the.
Further, a partition plate 14 is constructed by reinforced concrete along the spiral direction of the drop canal 12 to separate the drop canal 12 into a rainwater drop canal 1201 and a sewage drop canal 1202, wherein the wall of the drop canal 1, the drop canal 12 and the partition plate 14 jointly form the sewage drop canal 1201, the width of the sewage drop canal can be 0.5m, one side of the partition plate 14 far away from the wall of the drop canal 1 forms the rainwater drop canal 1202, the width of the rainwater drop canal 1202 can be 0.9m, the thickness of the partition plate 14 can be 0.1m, the rainwater drop canal 1202 is located below an overhaul ventilation opening 6, rainwater enters the rainwater drop canal 1202 through the overhaul ventilation opening 6, the sewage drop canal 1201 is communicated with a sewage pipeline 2, sewage enters the sewage drop canal 1201 through the sewage pipeline 2, and the drop canal 12 guides rainwater to the bottom of the drop canal 1 in a spiral conveying mode.
Firstly, sewage in the sewage pipeline 2 is discharged into the sewage drop channel 1201, the sewage drop channel 1201 conveys the sewage to the position of a sewage branch pipe chute 13 in a spiral conveying mode, then the sewage is discharged into the sewage pipeline 4 through the sewage branch pipe chute 13, the sewage drop channel 1201 pretreats settled sand and settled mud in the conveying process, no coarse garbage enters a working well, noise is gradually eliminated through wall reflection in the conveying process, energy is slowly consumed to a low-energy state through spiral conveying, the problems of sewage energy dissipation and noise elimination of the ultra-large ultra-deep drop well are effectively solved, correspondingly, rainwater on the ground enters the rainwater drop channel 1202 through an overhauling vent 6 and reaches the well bottom through the spiral conveying of the rainwater drop channel 1202, the conveying process can also achieve the technical effects of noise elimination, energy dissipation, sand settling and sludge elimination, and noise elimination and energy dissipation when the rainwater enters the drop well body 1 in a large flow are eliminated integrally, the spiral conveying mode does not need additional mechanical equipment, has no energy consumption, and can be effectively applied to the large-scale urban ultra-deep work inspection well.
In the above embodiment, the main purpose of building the drop canal 12 into the step structure is that, for the rain drop canal 1202, the rain drop canal 1202 can be used as a stair for maintenance while conveying rain water, so as to form a special maintenance channel for maintenance personnel, which is convenient for the maintenance personnel to go into the well for maintenance, and provides convenience and safety guarantee for maintenance personnel; for the sewage drop canal 1201, the stepped bottom surface is helpful to improve the effect of pretreatment of sewage, sediment and mud, and prevent the foreign matter and garbage from adversely affecting the drop well body 1, and certainly, the bottom surface of the sewage drop canal 1201 may not be provided with a stepped structure, for example, may be directly provided with a planar structure, and may also perform energy dissipation and noise elimination on sewage, but the pretreatment effect on sewage, sediment and mud is poor, and at the same time, it is not convenient to integrally construct the sewage drop canal 1201 and the rainwater drop canal 1202, which increases the construction cost, and thus, it is not a preferred embodiment.
Further, when the rainwater fall canal 1202 is used as an overhaul stair, in order to further improve the safety of the rainwater fall canal 1202, a stainless steel rail 15 is installed on the outer edge (i.e., the outer side) of the rainwater fall canal 1202, so as to further guarantee the safety of overhaul personnel.
Further, in the above embodiment, the isolation plate 14 is mainly provided to form an access stair on the drop canal 12 to provide a dedicated access passage for the service personnel, and the access passage can be used as a rainwater conveying passage at the same time, so that the purpose of flexible utilization is achieved. Of course, it is not limited to only one isolation plate 14 on the drop canal 12, and it is also possible to provide two isolation plates 14 or more on the drop canal 12 to divide the drop canal 12 into three parts, and in these three parts, the service passage is necessary, otherwise, it is not necessary to use the isolation plate 14, therefore, although the above embodiment only exemplifies the case of only one isolation plate 14, according to the concept of the present invention, it is not limited to providing one isolation plate 14. Accordingly, the relative position relationship between the rainwater drop channel 1202 and the sewage drop channel 1201 is not a mandatory requirement, but considering that sewage enters the drop well body 1 through the sewage pipeline 2 and the sewage pipeline 2 is directly communicated with the drop well body 1 through the well wall, in order to facilitate sewage discharge into the drop well body 1, the arrangement mode that the sewage drop channel 1201 is close to the well wall is preferably adopted, and the arrangement mode is also convenient for a maintainer to use the rainwater drop channel.
Further, based on the utility model discloses a design, the utility model discloses still include a rain sewage energy dissipation method who is applied to large-scale ultra-deep drop well, it includes following step:
step 1, arranging an overhaul vent 6 at the top wellhead of a drop well body 1, building a spiral step drop canal 12 along the well wall from the lower part of the overhaul vent 6 until the bottom of the drop well body 1, namely a sewage discharge pipeline 4, is built;
step 2, installing a partition plate 14 on the drop canal along the spiral direction of the drop canal 12 to divide the drop canal 12 into a sewage drop canal 1201 and a rainwater drop canal 1202, wherein the sewage drop canal 1201 is close to the well wall, the rainwater drop canal 1202 is close to the outer edge of the drop canal 12, and the outer edge of the rainwater drop canal 1202 is provided with a railing 15 to form a protection structure.
When the method for dissipating the energy of the rainwater and the sewage is applied to the ultra-large and ultra-deep drop well of the dry pipe project of the sewage in the scenic spot of the Heilongtan, the remarkable energy dissipation and noise elimination effects are achieved, the large delivery capacity and the large specification of the rainwater and the sewage of the ultra-large and ultra-deep drop well are caused, the technical effects of energy dissipation and noise elimination cannot be achieved by using the traditional energy dissipation mode of the drop well, and in the traditional energy dissipation structure of the drop well, a special maintenance channel is difficult to design, and when a maintenance worker overhauls the ultra-large and ultra-deep drop well, the safety threat is great.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
