Concrete Structure Using Hydraulic System and Noise-Free Vibration Construction Method of Structures Using the System {CONCRETE CONSTRUCTION USING HYDRAULIC SYSTEM AND ANTI-NOISE NON-VIBRATION MANUFACTURING METHOD OF CONCRETE CONSTRUCTION}

The present invention relates to a concrete structure using a hydraulic system and a noise-free vibration-free construction method of the structure using the same, and more particularly, to reduce the process, time and cost of construction in the construction site of a narrow and poor working environment, poor ground, underground or underwater The present invention relates to a concrete structure using a hydraulic system and a noiseless vibration-free construction method of the structure using the hydraulic system to greatly reduce risks such as safety accidents and to minimize noise and vibration generated during construction.

In general, when constructing buildings or structures in construction sites such as ground, underground, and underwater, construction of temporary foundation muds, construction of underground boxes or underground reservoirs, installation of other underground structures and foundation of river bridges in ultra soft ground, The construction of the structure is carried out through work processes such as the installation of underwater foundation facilities and the well drilling method.

In the temporary construction work using sheet pile or earth plate method, which are generally used in basic construction, the occurrence of safety accidents such as ground subsidence or collapse, and conduction of temporary construction facilities are inexpensive, especially in the case of the sheet pile method. Due to the basic elasticity of steel during construction in the ground, ground settlement is inevitable due to the generation of adjacent boundary cracks and the voids and vibrations of the seat where the pile pile is drawn. Both soil plate work and sheet pile method have the big disadvantage of disturbing and flowing stable foundation ground in soft ground by using vibrations such as shock and vibrator from working load delivered from large heavy equipment such as crane.

In addition, in the case of the well-hole construction method, which is constructed in parallel with the temporary film construction method in the water or ultra soft ground, the bottom of the well is excavated to be settled to fall naturally due to the weight of the well. The disadvantage is that it takes a lot of time to correct the settlement.

Conventional SCW (Soil Cement Wall) and CIP (CAST-IN PLACED PILE) methods are high in safety but require large heavy equipment and large accessories.In the process of construction, industrial waste such as sludge is generated and construction costs are high. There is a disadvantage.

In addition, the foundation work in waterfront areas, such as the foundation of bridges and pumping stations in super soft grounds such as rivers, is more costly due to more preparatory processes than the construction work, such as construction of barriers and construction of construction sites. There is a disadvantage in that it takes time and time.

As shown in FIG. 1 to FIG. 4F, the concrete structure using the hydraulic system according to the present invention is a three-dimensional concrete structure manufactured on the ground so as to be seated on the upper portion of the foundation pile 20 constructed in the ground, underground, and water ( 10); A plurality of hydraulic cylinders 15 coupled to the bottom or side surface of the concrete structure 10 to robotize the concrete structure 10 and having a cylinder rod supported on an upper surface of the foundation pile 20; The controller 30 is configured to control the driving of the hydraulic cylinder 15 according to the operation of the hydraulic pump 25 to operate the hydraulic cylinder 15 alone or simultaneously.

In addition, the construction method of the concrete structure using the concrete structure according to the present invention is the basement construction of buildings, large box construction for underground laying, wells construction for bridge pier, transmission tower foundation construction, river underground structure construction, civil engineering and construction, It is to allow the installation of facilities without temporary facilities or temporary curtains in basic construction such as underwater construction. After manufacturing the concrete structure 10 to be installed on the ground, the hydraulic cylinders 15 are installed on the bottom or side of the hydraulic structure. Structural manufacturing step of manufacturing a robotized concrete structure by the device, File installation step of arranging the head of the pile horizontally after constructing a plurality of foundation piles 20 on the ground on which the concrete structure is installed, and the head The hydraulic cylinder 15 is seated on an upper portion of the lower surface of the concrete structure 10 after supporting the concrete structure 10. The excavation step of excavating and cutting the unsupported base pile by the maximum drawing distance of the cylinder after operating the hydraulic cylinder of one of the hydraulic cylinder after the step so as not to support the foundation pile to the cut foundation pile After the base pile cutting step consisting of the process of drawing out and supporting the cylinder, and cutting each foundation pile sequentially while operating the hydraulic cylinders mounted on the concrete structure individually as in the above process, and then individually Simultaneously drive the hydraulic cylinder so as to approach the foundation piles cut and arranged horizontally, the concrete structure is lowered, and the excavation step and the foundation pile cutting step are repeatedly performed, and the concrete structure is lowered to the target point of the ground. Will go through a descent step, and then Is made in a bottom portion of a concrete structure 10 reaches the point through a finishing step of curing by pouring the concrete floor.
4A to 4F, the cutting of the foundation pile is described in more detail. The hydraulic cylinder 15 is mounted on the head of the foundation pile 20 to excavate the lower surface of the structure while supporting the concrete structure 10. 4a and 4b, the cylinder of one of the hydraulic cylinders 15 mounted on the head of the foundation pile 20 is driven so as not to support the foundation pile (see FIG. 4c). The base pile which is not supported by the cutting machine is cut by the maximum descending distance of the cylinder (refer to FIG. 4D), and after the cutting of the foundation pile, the cylinder is lowered and supported again. In this state, the cylinder of another hydraulic cylinder is driven to The individual foundation piles 20 are cut through the cutting process (see FIGS. 4E and 4F) so as not to support them.
That is, while the other hydraulic cylinder is operated in the same manner as described above, the foundation pile is cut and supported again, and when the cutting of the foundation pile of all sections is completed, the hydraulic cylinder 15 is simultaneously driven to operate the concrete structure 10. It will be descended little by little.

The hydraulic cylinder 15 is provided with a cylindrical outer structure using a high-tensile steel (EH steel) -based material having a high tensile resistance to the outside, it is integrally coupled to the concrete structure (10).

CYLINDER CAPACITY of the hydraulic cylinder 15 is determined to use the appropriate capacity according to the working environment, such as the weight and soil quality of the structure, the difficulty of the work, the safety of the worker, and grooving saddle (GROOVED SADDLE) Single-acting, double-acting, hydraulic return type large-capacity hydraulic cylinders are built-in.

Here, the operation of the hydraulic cylinder 15 is always checked the construction state during the operation, such as the hydraulic pump within 17BAR to 700BAR, the flow rate and hydraulic pressure or the load diagram and construction pressure due to the working load according to the load of the working pressure heavy weight. And a controller connected to the measuring device and the hydraulic pump to control the driving of the hydraulic cylinder 15.

The hydraulic cylinder 15 is a flange bolt binding member or a hook-type binding member, wall bolt fastening so that the hydraulic cylinder 15 when the construction does not deviate from the concrete structure by the total weight of the concrete structure, acting on the bearing force and reaction force Concrete structure by preparing and integrating high strength nut arrangement plate or flange or high tension nut arrangement plate that binds hook loop with reinforcing bar to be fixed at base of structure or bottom of wall by making coalescence base such as installation method of cylinder upper and lower fingerboard. Complete the structure of any plate, box, cylinder, polygon, etc. At this time, in the process requiring high pressing force (when pile press-in), the high-strength bolt is used to couple the flange type or wall fixing plate with the high-strength bolt. 15) can be combined with the concrete structure.

When the hydraulic cylinder 15 integrated with the concrete structure 10 is driven using a hydraulic pump, a measuring device, and a controller, a concrete structure in which an operator can start the concrete structure 10 as needed. {Hereinafter, it will be referred to as 'concrete structure robot' as the remote operation of the concrete structure is possible}.

That is, by attaching a drive device using the hydraulic cylinder 15 to the concrete structure 10 to make a concrete structure robot that can be adjusted to be driven up and down according to the purpose of the operator, the hydraulic cylinder 15 to the concrete structure ( The installation location of the hydraulic cylinder 15 may be determined and manufactured so as to secure and maintain the flotation force stably according to the weight of 10), work load, site condition, soil quality, and construction difficulty.

That is, the weight and working load of the concrete structure 10 is measured and calculated through a measuring device, and the installation location of the hydraulic cylinder 15 mounted to the concrete structure 10 based on the calculated value and the site conditions. And the installation interval will be determined.

The hydraulic cylinder 15 generates the kinetic energy generated by simultaneous driving and independent driving by the operation of the operator, the kinetic energy causes the concrete structure 10 to move up and down, and the amount and speed of the It is robotized by being controlled by a controller.

On the other hand, the coupling method of the hydraulic cylinder may have a number of methods in addition to the above-described method, it is sufficient if the coupling method is enough to provide mobility by coupling to the concrete structure (10).

The concrete structure robot according to the present invention is structured in various forms to allow the floating concrete structure to be cured by a hydraulic cylinder, which is fixed to the ground, underground foundation piles, molds, etc. Compared to the method of construction in a fixed state, construction has safety, speed and economics.

For example, in the case of underground construction, this method can be applied by forming an underground structure on the ground rather than in a narrow environment with poor working conditions and high risk of collapse, fall, etc. In particular, the work environment such as ultra soft ground, waterfront area, ocean, etc. It is useful to apply this method in the field where large heavy equipment, fill, substitution, temporary soil wall, temporary barrier, etc. are needed. Furthermore, the construction period and reduction of construction costs are omitted by omitting the filling work and replacement work for the use of large heavy equipment and the work processes such as temporary wall and clogging, which occupy a large part of the construction cost, among the auxiliary processes that are preceded for the main processes at the sites listed above. It can be said to be a construction method that can prevent safety accidents such as ground subsidence, collapse, and fall generated during temporary construction work.

Hereinafter will be described step by step for the construction method of the concrete structure of the present invention.

In the ground first to produce a concrete structure (10), if the basement process of construction to produce a basement box on the ground, in the case of the well-hole method, the well bucket is produced on the ground first,

Then, when fixing a plurality of driving devices equipped with a hydraulic cylinder (15) on the floor according to the weight and use of the structure by tightening the high-strength bolt in the form of a flange, in the process requiring maneuverability hook-type on the floor In the bottomless through-hole structure, multi-vertical arrangement of high-tension nuts at regular intervals in the bottom wall of the inner wall is inserted in advance, and the hydraulic system is fixed by bolt type. The concrete structure robot that can control the movement of the back is completed.

In this state, the hydraulic cylinder 15 is arbitrarily manipulated to allow the concrete structure to move with the kinetic energy generated by simultaneous driving with independent driving, and the movement amount and speed are controlled by using a controller to control the structure as needed. Support the cylinder stroke length of, and excavate the lower part by the volume of the structure and the stroke length of the hydraulic cylinder.

After the excavation, the hydraulic piles 15 are driven and driven up one by one, and the foundation pile 20 is cut by the maximum descending length of the hydraulic cylinders 15, and the hydraulic cylinders 15 of the cut portions are lowered again. Support on the foundation pile (20). Other hydraulic cylinders are supported after cutting the foundation pile in the same way.

In this process, when the foundation piles are cut to have the same length, the hydraulic cylinder 15 is driven simultaneously to lower the concrete structure 10, and when the construction is completed, repeat the cutting process of the foundation piles in the same manner. Then, when it is settled at the planned target point, the concrete is poured and cured.

As described above, the present invention can support the air in the air as long as the stroke length of the hydraulic cylinder 15 on the foundation pile 20, the concrete structure 10 manufactured on the ground, using the hydraulic cylinder ( After excavating stepwise by the stroke length of 15), and repeatedly cutting the pile by individually driving the hydraulic cylinder 15 provided on the foundation pile 20, the hydraulic cylinder 15 is simultaneously operated. Drive down the concrete structure 10 and repeatedly carry out it in several steps to settle the concrete structure 10 at the target point. The contact gap between the outer wall of the structure and the space that is destroyed is minute, By not allowing the space to collapse or fall down, there is no need to separately install the temporary soil wall, temporary wall construction and backfilling process. The cost savings and accident prevention due to the shortening of the construction period, the ground collapsed, including safety, cost-effectiveness, can be called with the process speed.

One embodiment of the present invention described above and shown in the drawings should not be construed as limiting the technical spirit of the present invention, concrete that is maneuvered by a self-hydraulic cylinder of ordinary skill in the art It will fall within the protection scope of the present invention as long as it will be apparent to those skilled in the art, such as manufacturing and constructing facilities using the structure.
