Description
Technical Field
The utility model belongs to the technical field of bury the blow off pipe and overhaul the construction, concretely relates to heavy-calibre buries a blow off pipe deeply and dams sealing structure.
Background
The large-diameter deep-buried sewage discharge pipe generally refers to a sewage discharge pipe with the diameter of not less than 1200mm and the buried position basically more than 6-8m, the buried position of the sewage discharge pipe even reaches more than 15 m in some special areas, the sewage flow in the sewage discharge pipe is large, the running water is high, taking the sewage discharge pipe with the diameter of 1500m as an example, the daily sewage flow of the sewage discharge pipe reaches 8 ten thousand tons, and the design pressure of the pipeline is 1.6 MPa; in order to facilitate regular maintenance, cleaning and dredging, inspection wells are generally arranged at the intersection of drainage pipelines, a turning part, a pipe diameter or gradient changing part, a drop part and a straight pipe section at intervals, the inspection wells are communicated with pipelines, and the water level in the inspection wells is at least higher than a drainage pipe; when the regular maintenance or the emergency repair and maintenance of the pipeline are required, the drainage pipe in the maintenance or emergency repair section needs to be blocked, and then the sewage in the interception section is discharged through the water pump; the blow off pipe shutoff is generally selected at the intersection of blow off pipe and inspection shaft, adopts rubber gasbag and brick wall to the mouth of pipe shutoff at the blow off pipe mouth of pipe, stops up the pipeline with rubber gasbag earlier, then builds a wall at the mouth of pipe, and the main following problem that has of current brick wall shutoff mouth of pipe in practical application:
1) the construction difficulty is high: the water level of the inspection well is higher than that of the drain pipe, the wall building at the pipe opening of the drain pipe is diving operation, different from the common wall building on land, the construction difficulty is quite large, and the requirement of the diving operation is provided for constructors because the constructors need to dive into water for construction;
2) the construction period is long: the wall building is that blocks are connected together through special cement, taking a drain pipe with the diameter of 1500mm as an example, the wall building is completed in all basically normal conditions about half a day, the wall dismantling is more time-consuming, the wall dismantling operation generally needs more than one day because the requirement of strong impact resistance of the wall is high and the adhesive force between the blocks is larger;
3) the plugging cost is high: the wall building plugging is operated in water, and the requirement on the impact strength of a wall body is high, so that the requirement on cement is extremely high, the adopted cement is special cement, a blow-off pipe with the diameter of 1500mm is taken as an example, the cost of the brick heads and the cement used for building the pipe orifice plugging wall is about 1 ten thousand RMB, when the overhaul or rush-repair operation is finished, the wall body needs to be dismantled, the cement and the brick blocks become waste products, the discharge amount of construction waste is increased, and the disposal of the construction waste needs to bear corresponding cost;
4) the construction risk is high: firstly, the wall building operation is completely submerged operation and has long operation time, sewage in the pipeline has various rotten objects, and the risk of long-time operation is high; secondly, if the rubber air bag at the front part cannot bear the impact of water drainage in the pipe in the construction process, the rubber air bag can be flushed out, the sealing brick wall collapses, sewage in a house can be flushed out at a more urgent and larger flow rate, constructors can be flushed away by the torrent in the pipe, particularly, when severe weather such as rainstorm occurs in the construction process or the upstream discharge amount is increased suddenly, the water level in an adjacent inspection well rises, the water flow in the pipe is more urgent, the impact force is larger, and the situation can cause that operators in the wall building and wall dismantling construction processes face a great risk of being flushed away by running water;
5) the danger of the overhaul operation is high: the risk is mainly caused by that the impact strength can not meet the related requirement due to the fact that the construction quality can not meet the set requirement, the wall building construction is diving operation, workers dive into sewage to build a wall, the working environment is extremely bad, the quality stability of the wall is subject to a plurality of human factors, for example, the proficiency of the workers, the sight obstacle of the diving operation, the cement curing condition in the field construction process and the like can possibly cause that the quality of the wall can not meet the set requirement, so that the impact resistance of the wall is reduced, when the maintenance or the emergency repair is carried out, rainstorm or the discharge of overlarge flow is encountered, the drainage capacity of a temporary discharge pipeline is often lower than that of a normal pipeline, so that the water level in an inspection well can be rapidly increased, the pressure born by a closure position can be rapidly increased, if the limit wall is exceeded, the wall can be washed down, and the staff carrying out the maintenance or the emergency repair operation in the pipeline can encounter, there is a risk of being washed away by the sewage.
In conclusion, the traditional wall building method for intercepting and plugging the large-diameter and deep-buried sewage discharge pipe has various defects, the plugging method which is low in cost, easy and safe in construction, large in impact resistance and stable is found, and the problem which needs to be solved urgently in the implementation of overhauling or rush-repair operation of the large-diameter and deep-buried sewage discharge pipe is solved.
