The present invention relates to a manhole breaker replacement propulsion method and the device, and in detail, to develop a propulsion method that can be applied to small diameter steel pipe propulsion method using a water jet excavation method suitable for domestic urban conditions, After the work is completed, it can be used as a manhole of sewage conduit as it is, and in addition, in connection with the repair and replacement method of the old sewage conduit that has been actively constructed in Korea recently, the manhole trench propulsion replacement method for replacing the old manhole with a new manhole And to the apparatus.

In recent years, the sewer pipe laying construction has been increasing by the non-adhesive technique represented by the propulsion method, instead of the conventional open method, due to difficult construction conditions and improvement of the construction environment. Among them, the small-caliber propulsion method with a propulsion diameter of 800 mm or less occupies about 80% or more of the entire propulsion work in the sewage business. Looking at the known manhole hole propulsion method known in the prior art, there is a Sibiche (CCB) Kecom-S method and the REVO method.

The CCB Kecom-S method installs all-rotary indenters and excavators (locates the all-rotator indenters in the mouth position, horizontally with out-riggers), and guide casing ( Rotational indentation and excavation of guide-casing is carried out, and rotational indentation and excavation is attached to the lower end of manhole block of concrete product, set in guide-casing, and then rotational indentation and adhesion starts. It is. In the case of ground with groundwater, excavation work is carried out while pouring water (to maintain balance with groundwater pressure).

In the connection of the block and the casing, after repeating the rotational indentation and excavation while welding and connecting the block, the temporary casing is bolted, the rotational indentation and the excavation work are carried out to a predetermined depth, After the excavation work is completed, install the bottom block and inject special grout material between the block and the bottom block.The completion of the manhole is carried out by washing the inside of the hole to complete the hole. It is a method to use as a manhole after completion of construction.

In the REVO method, a steel pipe casing is placed in the main body, press-fitted using shaking, and then excavate the soil in the casing underwater while maintaining a hydraulic pressure balance, and then casing again. After rocking indentation, excavate the earth and sand in the casing, and then place the underwater concrete using the injection pipe on the bottom, and after the underwater concrete is poured, the casing is drawn to the groundwater level, After hardening the concrete, the casing (Casing) to clean the inside is a method of completing the granules.

Looking at the conventional old manhole repair method, there is the ELL 100 (LLC) method, incineration of sewage sludge is mixed with clay, and repairs the inner wall of the old manhole using a ceramic tile at a high temperature, another The manhole lining replacement (Manhole Lining Renewal) method is known, a method for repairing the old manhole inner wall using a synthetic resin mold excellent in acid resistance and corrosion resistance is known.

On the other hand, temporary construction methods using H beams or sheet piles, which have been conventionally used to build manholes of small-caliber landscape propulsion, are designed to avoid traffic obstacles in accordance with increasingly difficult construction conditions. Construction should be possible within a short space within a short time, and in order to secure the safety of site workers as well as to prevent disasters of third parties involved in the construction, unmanned construction of the mine works involved in excavation is requested, and local residents In consideration of this, further prevention measures such as vibration, noise, ground depression, etc. accompanying construction are required, and these requirements are becoming increasingly difficult to apply in the city center. In addition, there has been a problem that the construction period is prolonged by increasing the traffic jam by manually replacing the manhole manufactured in a conventional factory on the road.

In order to solve the above problems, conventionally, the casing steel pipe is pushed vertically while pushing the oscillator to the oscillating pressure, and the earth and sand in the casing steel pipe is carried out to the ground by using an excavator, whereas, for the first time, It is a granular propulsion method that can be applied to the small-diameter steel pipe propulsion method using water jet excavation method without using the rocking indentation method. It is an object of the present invention to provide a manhole breaker replacement replacement method using the vertical propulsion method using the excavation force of a water jet and a device thereof by pushing a propulsion pipe or a manhole vertically underground while carrying out a ground part using a pump. It is a technical task to achieve.

In order to achieve the above object, the first part of the present invention is a system for excavating the propulsion pipe leading part (refer to FIGS. 2 and 3) of four sets of water jet drive systems and earth transfer pumps installed on the ground. The water jet water supply pipe and the sediment suction pipe connected to the system are connected to the propulsion pipe leading part, and the mixed solution such as water and abrasive is sprayed through two water jet injection exposures set at 45 ° C in both directions, respectively. Pre-excavate the soil and suck water from the soil suction pipe inlet of the soil transfer pump installed 30 ~ 50cm above the water jet spray nozzle. While discharging, it plays a role of gradually pushing the propulsion pipe vertically.

The second part is a rotary excavator moving device located at the upper part of the propulsion pipe (see Figs. 2 to 4), and attaches a turning ring gear in a circular shape around the upper surface of the propulsion section, and includes a water jet water pipe and a soil discharge pipe. The box-type device is a rotary excavator by the driving of the rotary motor for moving the excavating device is responsible for causing the rotary movement along the turning ring gear.

In addition, the rotary excavator moving device constitutes four sets, each of which is connected to four sets of water jet driving system and the earth transfer pump system installed on the ground, and is connected to each rotary excavator moving device. Was able to excavate and discharge the head of the propulsion tube while reciprocating the rotation angle of 90 °.

The third part is the propulsion lead blade and propulsion pipe. The propulsion lead blade is made of steel so that the tip is sharpened so that it is less resistant when it is pushed vertically to the ground. Steel pipes should be used as bases or reach bases, and concrete manholes or resin polymer manholes can be used to construct manholes or replace old manholes. Thus, the propulsion pipe and propeller blades were not separated during vertical propulsion.

The fourth part is a hydraulic propulsion pipe lifting device <see Figs. 1 to 4> by fixing the ground to the ground by using a ground fixing anchor of the lower end of the propulsion pipe lifting device consisting of four sets (set), and then the outer surface of the propulsion pipe In order to protect the propulsion tube, the propulsion tube is supported by the propulsion pipe support belt. Progress gradually.

The fifth part is an inner casing pipe and an inner casing pipe support (see Figs. 1 and 3). The casing steel pipe is installed inside the propulsion pipe by using a support to protect the water jet supply pipe and the soil discharge pipe from the internal soil. The support was divided into four quarters and four at 90 °. After the propulsion work was completed, the support was demolished, and the inner casing steel pipe could be recycled at the next construction to reduce the construction cost. In addition, four sets of rotatable excavator moving devices were allowed to perform a 90 ° reciprocating motion around the support.

The construction procedure of the propulsion method of the granules for use as a forward device or the reaching base of the small-caliber propulsion method or the installation method of the propulsion method for installing a new manhole is shown in FIGS. 7 to 11. After the pipe lowering device is installed around the propulsion pipe, the propulsion lead blade and the first propulsion pipe are held in close contact with the hydraulic lifting device, and then four sets of water jet drive and earth transfer pump are installed on the ground. Drive and progressively propel the propulsion pipe vertically while performing excavation and earth discharge through the water jet injection device and the soil suction pipe, respectively, and excavate the earth and sand inside the inner casing pipe by using the in-pit earth excavation device. To the ground.

After the propulsion is completed, withdraw the inner casing pipe support and inner casing pipe, the rotary excavator moving device and the turning ring gear, the water jet water pipe and the soil suction pipe, and then install the ground block on the ground. After that, the floor is completed by injecting the special bonding grout material, and when the groundwater is present in the inside of the manhole (manhole), the bottom is completed by injecting underwater concrete into the floor using a Doremi tube. And in the case of the manhole, the hole is connected to the sewer pipe in the inner wall of the manhole for the connection to the sewer pipe, using the connecting material, the connection work with the sewer pipe, install the manhole cover and finish the construction.

The use of this method to replace the aging manhole can be divided into two ways. If the new manhole is larger than the old aging manhole (see Fig. 12 to Fig. 15), the inner casing and propulsion pipe outside the existing manhole. Vertical propulsion work was carried out with the manhole in place, and the sewer pipe connected to the old manhole was cut by water jet injection. After the propulsion work was completed, the waterjet concrete cutting device was taken into the old manhole to cut the lower part, and the old manhole was taken out to the ground using a towing crane device on the ground and discarded. Then, after the bottom block and the special grout material is injected to form a floor, the connection pipe is connected inside to allow easy connection with the existing sewer pipe. If the new manhole is smaller than the old manhole (see Figs. 16-19), the water jet injection device was used to vertically propel the old manhole by cutting the new manhole propulsion pipe and the inner casing pipe. After this is completed, after removing the residue in the inner casing pipe, the bottom block and the special grout material is injected to form a floor, and the connection work with the existing sewer pipe using the connection pipe inside the new manhole. Thereafter, grout material or mortar is injected and filled into the old manhole and the new manhole gap to be integrated.
