Description

Interlocking block and port structure using interlocking block and construction method of port structure using interlocking block {Interlocking block And Port structure using interlocking blocks And Construction method of port structure using interlocking block}

The present invention relates to a port structure, and more specifically, to secure the stability of the port structure by securing the fastening force between the upper/lower/left/right blocks, to prevent relative displacement and unequal settlement between blocks with shear resistance, to reduce costs and construction costs, and to In addition, it relates to an interlocking block and a port structure using the interlocking block, which can secure economic feasibility due to the improvement of construction quality, and a method of constructing a port structure using the interlocking block.

In general, a port consists of water body facilities and outlying facilities where ships can safely enter and depart, mooring facilities such as a quay wall where ships can dock and load and unload passengers or cargo quickly and safely, and industrial complexes behind cargo. The port transportation facilities for transport should be basically provided, and functional facilities and support facilities to build a high value-added port cluster and foster it as a comprehensive logistics base should be comprehensively linked.

In particular, the quay wall is a ship mooring facility with a wall made for boarding/unloading of passenger ships and loading and unloading of cargo. A wall built vertically in the sea direction of the pier so that ships can safely dock and handle cargo and passengers. In other words, it is a mooring facility with a front water depth of 4.5m or more, and refers to a quay facility where ships of 1,000 tons or more are docked.

According to the structural type of these quay wall structures, they are divided into gravity type, pier type, shelf type, steel pile type, and auxiliary pier. Other types of quay walls such as steel piles and floating piers are distributed around 3%.

In addition, the gravity-type quay wall can be classified into an interlocking block type, a caisson type, and a cellular block type according to the structure used for the wall. When looking at the cases, interlocking block type (79%), caisson type (15%), and cell block type (6%) were investigated. Therefore, more than half of the quay wall structures in Korea, more than 60%, are gravity-type quay wall interlocking block type.

Gravity-type quay walls are designed to resist external forces such as earth pressure, water pressure, and superimposed loads with the wall's own weight and frictional force by excavating to the seabed support layer with a solid foundation, forming a mound with foundation stones, and then mounting an interlocking block or caisson or cell block as a structure. As a structure type, the advantages of this type are simple construction, good constructability, and easy maintenance. However, compared to the pier-type quay wall, the construction period is relatively long and the initial construction cost is high.

The interlocking block type is a form of pre-fabricating interlocking blocks on land with unrooted concrete, mounting them in several stages on the foundation stone, and then pouring concrete on the top to complete it.

It is the most commonly applied construction method because it can be constructed with relatively small offshore equipment, but it has the disadvantage that it requires a lot of construction cost.

The caisson type requires a launching facility for the caisson in the series of processes of manufacturing the caisson of a large concrete enclosure on land or on a floating dock and mounting it at the planned location by an offshore crane or tugboat, etc. Therefore, sufficient water depth must be secured, and the caisson must be filled immediately after installation to prevent displacement of the caisson.

It has good structural integrity and has the advantage of shortening offshore work time, but it requires large offshore equipment, requires high construction costs, and has difficulties in use if the planned schedule is not met. There is a disadvantage in that it is rather uneconomical because it takes a lot of cost for preparation facilities to install it.

The cell block type is a form in which a box-shaped hollow block made of reinforced concrete called cellular is manufactured in advance on land, mounted on the foundation gravel, filled inside the cell with gravel, etc. Although the cost of construction is lower than that of the formula, the construction management process is very complicated compared to the progress by repeating the process of multiple types of construction several times, so additional equipment is required, 11) has many disadvantages.

Here, a detailed look at whether the interlocking block type is widely adopted among the structures of the quay wall is as follows.

First, the caisson type is economical in a large quay wall structure with a long quay wall extension, even if the caisson manufacturing and launching facility costs are higher than other types. That is, since the filling material in the caisson compartment can be replaced with a material cheaper than concrete, the filling material is generally sand, crushed rubble, sandstone, and steel slag.

A caisson is usually a large concrete enclosure of 1,000 tons or more, and its size is at least B 20m×L 8m×H 15m or more. Accordingly, the caisson type requires large offshore equipment, and if the caisson is not filled immediately after the caisson is mounted, there are many cases of deviated from the construction baseline and remounted due to waves and sailing waves.

And, the cell block type is a box-shaped hollow block, and the upper and lower surfaces are open. In a series of construction processes that fill the inside of the cell with a filling material after the cell block is completed, the multi-step construction process is very complicated, and the sea work time is long, which makes the construction management vulnerable. On the other hand, the disadvantage is that it is difficult to select workers due to environmental imperfections, while the construction cost is cheaper than the interlocking block type.

On the other hand, the interlocking block type has the disadvantage that it requires the most construction cost per unit m, but it is relatively easy and safe compared to other types such as quality control, safety management, and construction management, and it can be constructed with small-scale offshore equipment, and the construction period is short. This short length is referred to as the most widely adopted construction method for quay wall structures.

Meanwhile, interlocking blocks, a gravity-type structure that accounts for 79% of the quay wall structures that are mooring facilities, are unrooted concrete with a width of 2 to 4 m, a thickness of about 2 m, and a length of 4 to 8 m. It is urgently necessary to improve whether or not to manufacture it, and the upper concrete of the breakwater, which is an outer facility, is a huge mass concrete structure. The unit construction cost is very high as the construction cost is very high, and since most concrete pouring is done at sea, it is necessary to urgently improve the reduction of the construction cost and the shortening of the construction period.

1 and 2, the reason that the role of the shear key is not reflected in the design in the current design standard is because the clearance gap of the shear key is about 5 cm to 10 cm. However, if the self-weight of the structure is reduced, the harbor structure is pushed as much as the clearance gap, and there is a problem that the overall distortion occurs with respect to the normal line of the entire structure.

Hereinafter, the present invention having the above schematic configuration will be described in more detail to facilitate implementation.

The interlocking block 10 of the present invention is formed with a long length of a rectangular cross-sectional shape as shown in FIG. 4 by using concrete, and a pair of protrusions 12 are formed on both sides 11 in the longitudinal direction to alternate with each other.

Here, the protrusion 12 is a core technology of the present invention for securing the crushed stone filling space 20 between the side surface 11 and the inner surface of the protrusion 12 .

That is, when the protrusions 12 of the interlocking block 10 are installed in a line so as to be in close contact with the side surface 11 of the other interlocking block 10 as shown in FIG. 5, between adjacent interlocking blocks 10 A crushed stone filling space 20 that can be filled with crushed stone can be formed.

This crushed stone filling space 20 has a rectangular shape between the protrusion 12 and the side surface 11 as the protrusions 12 of a pair of adjacent interlocking blocks 10 are positioned on the same line in the front-rear direction. formed to achieve

Therefore, the crushed stone filling space 20 can be filled with crushed stone to form crushed stone pillars 30, which are shown in Figs. By interlocking a plurality of interlocking blocks 10 installed in multiple stages in a line in the normal direction of the port structure (S) or the water landing (L), the port structure while maintaining the fastening force between the upper and lower interlocking blocks (10) more firmly (S) provides stability and provides the effect of minimizing the relative displacement between the interlocking blocks 10 due to the shear resistance between the crushed stone pillars (30).

It effectively prevents the crushed stone filled in the crushed stone filling space 20 from leaking to the outside.

In addition, the interlocking block 10 is an auxiliary protrusion ( 18) is formed to protrude, respectively, and these auxiliary protrusions 18 are installed compared to the general interlocking block 10 even though the port structure S of the same length is constructed by expanding the left and right thickness of the interlocking block 10 as a whole. It provides a special effect that can significantly reduce the construction cost.

On the other hand, the interlocking block 10 must be installed in multiple steps upward in a state in which they are installed in a line in order to construct a port structure.

That is, the construction method of the port structure using the interlocking block configured as described above is as follows.

According to FIG. 19 , there is a step (S10) of reinforcing the ground of the seabed and installing the sandstone mound 40.

There is a step (S20) of configuring the first word assembly 100 by installing the interlocking blocks 10 in a line on the sandstone mound 40.

There is a step (S30) of configuring the second word assembly 200 by stacking the interlocking blocks 10 in a line so as to be in the opposite direction on the upper end of the first word assembly 100 (S30).

There is a step (S40) of configuring the third word assembly 300 by stacking the interlocking block 10 on the upper end of the second word assembly 200 in the same direction as the first word assembly 100.

The crushed stone filling space 20 formed between the interlocking blocks 10 is filled with crushed stone to form crushed stone pillars 30 (S50).

It has a step (S60) of pouring concrete on the upper end of the third word assembly (300) to form the upper concrete (50).

Here, after the forming step (S60) of the upper concrete 50, a step (S70) of filling the backfilling rubble 60 in the rear of the first, second, and third-level assemblies 100, 200, and 300 is performed.

At this time, the step of laying the filter mat 61 on the surface of the backfilling rubble 60 (S80), and after embedding the buried soil 62 in the upper part of the filter mat 61, the standing concrete 50 and the horizontal surface It may further include a step (S90) of paving the pavement path 63 to achieve this.

After the construction step (S40) of the third word assembly 300, an additional assembly ( 400) can be further configured.

On the other hand, after the installation step (S10) of the sandstone mound 40, the step (S100) of installing a foundation block 70 having a plurality of grooves 71 corresponding to the sandstone mound 40 may be further included (S100). .

For this purpose, a plurality of interlocking blocks 10 installed in a line constitute the first word assembly 100 as shown in FIGS. 5 and 7 , and at the upper end of the first word assembly 100 as shown in FIGS. The second word assembly 200 is constructed by stacking other interlocking blocks 10 in a line so as to be opposite to the first word assembly 100, and at this time, the interlocking constituting the second word assembly 200 is The protrusion 12 of the block 10 is installed in multiple stages by being stacked so as to overlap the upper end of the protrusion 12 of the interlocking block 10 constituting the adjacent first word assembly 100, the first stage assembly 100. And the second word assembly 200 exhibits the same effect as repeatedly masonry zigzag mutual bricks can be maintained even more robust.

And on the upper end of the second word assembly 200, the interlocking block 10 is laminated in the same direction as the first word assembly 100 to constitute the third word assembly 300, so that in the end, the second word assembly 200 ) and have the result that the third word assembly 300 is stacked in the opposite direction.

The first word assembly 100, the second word assembly 200, and the third word assembly 300 are large in size with a wide front and rear width of the port structure (S). It is also possible to install them in parallel to achieve this.

In addition, the interlocking block 10 is additionally grafted with a technology for maximizing shear resistance.

As a technical configuration for this, as shown in FIGS. 11 to 12, the protrusion 12 on the opposite side to which the wave pressure is applied and the shear resistance groove 15 are recessed at the lower end, and the shear resistance is formed at the protrusion 12 and the upper end. The interlocking block 10 stacked in multiple stages by forming the shear resistance jaw 16 corresponding to the groove 15 exhibits excellent workability by further strengthening the shear resistance generated in the front and rear directions while maintaining a solid upper and lower binding force. The crushed stone filled in the crushed stone filling space 20 is not pushed further by the shear resistance sill 16 even when wave pressure is applied, and maintains the rigidity of the crushed stone pillar 30 It provides a special effect that can withstand the pressure more efficiently .

That is, as shown in Fig. 18, the shear resistance groove 15 and the shear resistance jaw 16 respectively correspond to the upper and lower block body 10a, and when the interlocking block 10 is constructed by lamination without play. Even if the wave pressure is irregularly generated from the outside, the interlocking block 10 into the harbor can withstand the normal without deviating from the normal line.

Accordingly, an unnecessary process of forming the knot groove 17 and the binding protrusion 17a on the side surface 11 can be eliminated, and the interlocking block 10 can reduce the weeding cost.

Next, the construction method of the port structure using the crushed stone pillar 30 and the interlocking block 10 of the present invention having the above-described configuration will be described.
