Description

The old method of continuous partial work for anold and timeworn sewer pipes

The present invention relates to the continuous sewage pipe continuous partial repair method and its chapter, which will be described in more detail, to continuously process the process of cleaning the old sewage pipe, in particular concrete pipe, preliminary treatment of damaged sites, intensive maintenance of damaged sites, etc. It relates to a aging sewer pipe continuous partial repair method ("CPRS process" named by the applicant) and a device thereof.

The first official sewer was recorded as an extension of 468 m of sewage, built in Montmartre, Para, in 1370, and then by the mid-World War II, it was aimed at increasing the sewage system in order to catch up with the tide of the ages to address the spike in demand. Put it. The concept of comprehensively designing and planning a sewerage network system by introducing the network concept to the sewer system that has been indiscriminately unintentionally in the 1850s and not only a specific pipeline, It began in Western Europe, centered in the Americas, and in the Americas, centered in New York and Chicago.

However, since the 1970s, the main water and main pipes, the main supply line of water, and the collapse of sewer pipes have increased dramatically. Knowing that this is the result of decades of neglect of maintenance on conduits, the necessity of repairing or replacing old pipes to extend the life of the semi-permanent facilities has emerged. Emerged into the matter.

At this time, when there was no technology related to the repair and reinforcement of sewage pipes, the only way to repair the old ones was to enter the sewer pipe, partially repair the missing parts, and in extreme cases, to replace all the sewer pipes with new ones. How to replace was only. The two methods were unreasonable, such as exposing the worker to the risk of safety accident in the former case, and considering the inconvenience and enormous waste of the long time road control in the latter case.

Since the mid-1970s, new concepts for repairing sewage systems have been developed like a bamboo shoot from year to year. The new methods can be used only if the existing sewage pipes are structurally intact and the water supply capacity is adequate or adequate, the method to restore the structural capacity of the sewage pipes to its original state, and the infiltration / inflow of the sewage pipe system (Infiltration / Inflow). In addition, various methods have been developed, such as a method of effectively increasing water supply capacity by reducing I / I).

About 80 kinds of sewage rehabilitation methods and pipeline rehabilitation techniques are used worldwide for the sewage pipe maintenance, and the classification work to systematically classify them is performed by ISTT, CEN, WEF & ASCE. This was done at the institution. However, there are many similar concepts, such as overlapping or modified / improved methods, and there are unregistered methods, but the same concept, but different names depending on the materials and work methods used, and not all developed methods in each country. The international standard classification system of sewage pipe maintenance and reinforcement law has not been established.

Among these, the excavation method is simple in its concept and equipment / materials, while the non-excavation method is subdivided according to the object, purpose, and characteristics of the method, and replaces existing pipes without digging. It can be divided into renovation method that repairs the pipe while keeping it as it is. In the past, when the diameter was more than 500 mm, the worker went into the sewer and worked, but as the awareness of the safety of the working environment is heightened, the robot equipped with CCTV and repair equipment is replaced by the non-excavation repair.

Here, non-excavation method of sewage pipe repair / reinforcement method means that cracks, short circuits, steps, leaks, wall loss, depression, seam loosening, connection breakage, connection due to the increase of stress caused by poor construction or repeated load Relying on conventional excavation replacement methods in case of failure to maintain structural strength due to defects such as pipe protrusion / relaxation and breakage of manholes, and inability to perform sewage transport due to increased penetration / inflow through damaged parts The existing sewage pipe maintenance system is equipped with state-of-the-art equipment and special lining materials (tubes) to repair various defects in a short time without excavation of the road, and to maintain the strength and roughness coefficient of the new fuse and durability that is equivalent to about 50 years. New concept of sewage pipe maintenance technology that can be reborn.

A-1) Non Excavation Method

Non-excavation method is a technology that minimizes or completely eliminates the need for excavation, and is an engineering technology for installing and repairing pipes, water pipes, cables, etc. in the basement. Non-excavation methods can be applied in various ways, from installation of fuses to replacements and renovations of existing pipes.

1) Fuse Installations

Tube installation methods are generally classified into propulsion methods, shield methods, and the like. The propulsion method is a method of embedding the conduit by pushing the conduit from the oscillation shaft to the hollow shaft with a jack. There are a cutting edge propulsion technique, a semi-shield technique, a traction propulsion technique, and a small-caliber propulsion technique. Here, the small-caliber propulsion method is classified into 30-50 types. The auger method and the slurry pressurization method are called microtunnel methods in the West.

The shielding method is to build a conduit by pushing a solid forged outer shell called a shield with a cross section slightly larger than the conduit, excavating therein, and performing work such as primary and concrete reconstruction.

2) Replacement

If the condition of the pipeline does not improve under any repair or reinforcement method, it is advisable to make a complete replacement. Usually this condition is specific to a particular area, and in other areas it is economical to apply partial or full remuneration. In the case of hydraulic overload, the repair and reinforcement method will not be effective. Therefore, the existing pipeline should be replaced or the auxiliary sewer pipe should be constructed.

In recent years pipe bursting, microtunneling, directional drilling, fluid jet cutting, impact moling, impact ramming, auger Non-excavation replacement techniques, such as auger boring, have been used. In less crowded areas, narrow trenching may be used to minimize excavation.

3) Renovation

Even if the function of the conduit is unsatisfactory, it is appropriate to reconstruct the tube rather than replace it if the structural value remains. Before starting any maintenance work, the condition of the pipe must be checked. It is often more economical to repair a tube than to replace the entire tube if the condition of the tube is structurally fragile, or if it is structurally normal but hydraulically poor.

The sewer rehabilitation method uses existing structures to form part of the pipeline or to create new linings, which can be divided into three categories: pipe linings, segment linings, and structural and nonstructural coatings.

① pipe lining

Pipe lining is to install lining continuously or in short section inside sewage pipe. It is applied to sewage pipe of various size and cross section by using slip lining (continuous pipe and single pipe), field hardening pipe (CIPP), deformation pipe, and pipe making method. can do.

Cured-In-Place-Pipe (CIPP) is a domestically developed technology developed by (1) a method of inserting a liner for insertion into a tube and (2) curing the inserted liner. There are three main types according to the method.

First, the INS method, the SWED method, and the IN-LINER method are used to invert, insert, and heat the liner using water pressure. Introduced in Korea, the plan to move the reversal position of the liner from the upper part of the scaffold to the lower end of the manhole was devised to improve workability and material saving.

Secondly, the liner is towed by a winch and introduced into the pipeline, and then expanded using air pressure to thermally cure. There are a SUPER LINER method and an SZ method. It was introduced in Korea and devised a way to cure nonwoven fabrics in a short time by using hot air during construction.

Third, there are HOSE-LINING, PHOENIX, etc. as a method of thermosetting after inverting and inserting the liner using air pressure.

② segment lining

Segment linings are suitable for sewer pipes with diameters greater than 42 inches (1,050 mm) and are available in a wide variety of configurations. For structural reasons the seams should not be located near the well. Segments are installed through manholes with their lids removed or through specially designed tools if they are not easily accessible.

Segments should be installed in a dry state or with little water, so the flow direction must be dispersed or the sewage must be diverted. The annular space between the lining and the existing conduit is infused with high strength grout at relatively low pressure (34.5 kPa (5 psi)). Segment liners are made of many different materials to increase their resistance to corrosion. Thin linings can be used in combination with cast-in-place concrete to prevent corrosion, or grout can be injected into the surrounding ground after installation. Segment lining is designed as a composite lining where existing conduits and grouts work together.

③ structural and non-structural coatings

In situ coatings are used to increase the strength of existing conduits or to increase their service life by protecting existing structures from corrosion or wear. This method also improves the water capacity.

In coating work, shotcrete and cast-in-place concrete are used only for sewer pipes larger than 1,200 mm (48 in) in diameter. If the amount of infiltration is large, it is difficult to work, so a control method is required before and during the work.

In Korea, it is very rare to have a conduit that maintains its rehabilitation function for more than 20 years. As well as sewage pipes, other facilities buried underground were also installed along the roads, so the roads of Korea were left to be found on the road after 10 years of opening. Therefore, a new repair and reinforcement method is needed under the premise that physical replacement alone cannot solve the fundamental problem.

In order to solve the problems as described above, the present invention has been developed a method that can continuously perform the process of cleaning the sewage pipe, preliminary treatment of the damaged area, intensive maintenance of the damaged site,

First, by using the sewage transfer pipe and sewage transfer pump between the sewer pipes except the section where the partial repair method is implemented, the special protection cover is used to bypass the sewage to the ground and to prevent obstacles to the vehicle operation on the ground. The sewage can be transported using casing so that the sewage flow does not interfere with the partial repair process.

Second, it was able to drastically reduce the daily process and construction costs by cleaning the wastes and wastes in the sewer pipes subject to partial repairs, and at the same time performing the partial repair method consisting of various process units.

Third, in the partial repair method, the rapid freezing method using liquid nitrogen was applied, and the tree roots, etc., in the damaged sewer line were prematurely necrotic to prevent damage to the sewer pipe in the future.

Fourth, the maximum efficiency of the strength reinforcement and reinforcement process of broken sewer pipes was obtained by using glass fiber and reinforced fastening concrete.

Fifth, the entire process of partial repair including sewage pipe cleaning is carried out by using a continuous working unit, which shortens the air and reduces the construction cost compared to the work processes and methods that were performed through each individual construction process. It is a technical problem to be achieved by the present invention to provide an old sewer pipe continuous partial repair method (CPRS method) and the device that can bring about the effect.
