Description
Technical Field
The invention belongs to the technical field of plugging devices, and particularly relates to a plugging device for a drainage pipeline.
Background
Many drainage pipe networks in old cities of domestic cities are seriously affected by running, overflowing, blocking and leakage due to overdue service and long-term overhaul, and especially in rainy seasons where geological disasters are easy to occur, the conditions of pipe canal leakage and road collapse frequently occur, so that serious adverse effects and potential safety hazards are brought to the life and traveling of urban residents.
At present, drainage pipelines are blocked in a plurality of ways, and the general method is divided into three categories: temporary facility plugging, fixed facility plugging and tool plugging. The method mainly comprises the following steps:
(1) plugging a gunny bag: the method is applied to plugging of medium and small-sized drainage pipes and canals which lack reliable plugging equipment, are short in plugging time and are low in water pressure; its advantages are low cost and suitability for pipe channels of various diameters and cross-section shapes; the disadvantages are poor reliability and durability, and difficulty in removal.
(2) Plugging a wall body: wall body plugging can be divided into brick wall plugging and block plugging, and at present, large-scale and ultra-large-scale drainage pipe channels are influenced by various adverse factors and lack of reliable plugging devices and equipment, so that external water is guided to reduce the water level in the pipe channels, and then manual underground operation wall building plugging basically becomes the most common or even the only feasible measure in the current industry; the device has the advantages that the device is suitable for pipe ducts with different pipe diameters and section shapes, and the use safety coefficient is high; the defects are that the danger of manual underground operation is high, the dismantling cost is high and is extremely difficult, and the operation management is adversely affected due to the insufficient water passing capacity of the drainage pipe channel caused by the fact that the wall plug is not completely dismantled.
(3) Air bag plugging: the plugging agent is generally applied to plugging of medium and small-sized pipelines, and few practical cases of large-sized pipelines are also available; the sealing device has the advantages of convenient use, wide application conditions and effective sealing; the air bag has the disadvantages that the air bag is scratched by the surface barb of the drainage pipe canal due to material reasons to cause greater potential safety accidents, and the larger the pipe diameter is, the smaller the water head pressure born by the air bag is, and the greater the danger is. Major safety accidents are caused by airbag rupture at home and abroad, such as America and the like, and the situation that an oversize pipeline is plugged by adopting an inflation tube plug at home and abroad is rare.
(4) A water stop plate: the water stop plate is a non-standardized tool and consists of a wood plate, a rubber plate, a sponge water stop strip, a support and the like; the pipe duct plugging device has the advantages that the pipe duct plugging device is suitable for pipe ducts with various sizes and section sizes, safe in operation, effective in plugging and convenient to install and dismantle; the defect is that the device is only suitable for inspection wells and circular well walls with pipe orifices not provided with mud grooves.
(5) A slot gate plate: the flashboard gate belongs to a fixed facility and consists of a gate slot and a flashboard; the advantages are convenient sealing and dismounting, safety and effectiveness; the disadvantage is that it can only be used in a few places where the sluice trough and the associated hoisting equipment have been installed.
In the plugging method, for drainage pipeline plugging and water guiding, except for a fixing facility for fixing a slot flashboard which is already built at the initial stage of pipeline construction, air bag plugging is widely applied in recent years, but the dangerous situation of air bag puncture is easy to occur due to the influence of various factors in the air bag plugging, and the serious loss caused by air bag damage occurs at home and abroad every year.
