Abstract

The present invention has four main walls of relatively low height, and has a unit caisson with upper and lower openings, and forms a male key and a male key on the upper and lower sides and several sides of these caissons so that the male key can be inserted into the female key. It is about the design of a structure for constructing an upright pier using caissons having the same effect as a caisson upright pier, which is connected by installing one caisson, which is conventionally at a constant pier height, in a row by vertically stacking in multiple stages. .

Description

A constructed structure of upright quay which is used caisson}

The present invention relates to a technical field for constructing a pier, which is a facility for anchoring and mooring a vessel safely on the coast. The pier to which the vessel is docked as described above is generally gravity-loaded and piled according to its structure. There are sheet piles, bridge bridges, bridge bridges, etc., and there are characteristics of structural analysis, which are selected according to the needs. Generally, the walls are made of concrete, have good durability, and are constructed relatively. Many simple and easy gravity structures are used. These gravity structures can be further subdivided into caisson, block, cellular block, and L-block. The construction of the caisson-type structure, which is the most widely used among them, is the most stable as an upright body, and it is also robust against external waves. A structure that can be built for two.

As described above, the caisson type as a pier body for constructing the berth of the ship has the structure that the unit caisson has a bottom surface and has four main walls and is divided into a plurality of reinforcing walls therein, and the upper surface is an open structure. It is possible to build a quay with a relatively simple but solid structure. As the height of the unit caisson becomes the height of the quayside, the weight and volume of the unit caisson (normally 8 ~ 10M ³ ) are enormously large and heavy, so that problems such as extra-large cranes should be mobilized for moving and mounting work. Entails. In addition, the unit block size is small (about 2M wide), which is made up of four main walls and the hollow blocks (S) opened up and down to build the required pier height and hollow out high quality sand or sandstone in the interior space. As the block type is a hollow block is stacked in a stepped cross-sectional view as shown in the cross-sectional view of Figure 2, the upper side hollow block as shown in FIG. Since it is very difficult to form a special fastening and fixing structure at the connection welding part of the over and under hollow block, there is no structure that can cope with the horizontal lateral force applied from the outside. There is a problem that only limited construction of small pier.

The present invention eliminates the structural defects of the conventional caisson type upright breakwater and hollow block type upright breakwater as described above, and combines only the merits of both, so that the construction of a pier can be constructed without the mobilization of extra large crane even in the construction of large pier. The invention will be described in detail with reference to the accompanying drawings, but the structure of the unit caisson implemented in accordance with the present invention will be described with reference to FIG.

FIG. 6 is an exploded perspective view of a conventional caisson type upright wharf as a lower caisson C positioned at the bottom of the caisson placed on the bottom of the sea bottom F and an upper cai Ca stacked in a plurality of stages at an upper side thereof. Wherein one caisson is to be the height of the entire quay compared to the caisson is carried out in the present invention is to lower the height to stack a plurality of caisson to the height of the normal caisson type upright pier bar caisson unit cai When explaining the structure of the structure, the ratio of the aspect ratio to the plane is 10: 12, and the plane of the constant thickness (h / n (h) when h is the total height of the port) 4, The main walls (1) (2) (3) (4) are to be placed, but the two main lengths (1) and the male keys (5) having a constant thickness and width perpendicular to the middle part of the outer wall of the main wall (3) Dimensions inserted correctly The key is formed in the shape of a key, and the key (6a) (6b) (6c) (6d) is equal to the size of the male keys (5a) (5b) (5c) (5d) of a certain size in the middle of the upper surface of the four main walls of the unit caisson. The lower caissons C, which form the upper caissons Ca, and which are placed on the bottom surface base 9 of the bottom surface, are respectively divided into three middle portions of the four main walls 1a, 2a, 3a, and 4a. ) (5b) (5c) (5d) is protruding but there is no dimness on the bottom of the 4th main wall and the bottom is sealed by the bottom 7 and the outer circumference of the main wall 1a and the main wall 3a of the 4 main walls of the lower caisson C. The lower caisson (C) and the upper caisson (Ca) implemented in accordance with the present invention are formed by protruding and injecting the male key 5 and the female key 6, respectively, perpendicular to the middle of the wall, and the lower caisson (c) and the upper caisson. (Ca) Inside, a plurality of (two in the drawings) support walls 8 and 8a are partitioned in to form a unit caisson, and the lower caisson C is fixedly fixed to the upper surface of the seabed base end F. And ha Lay the upper caisson (C) in multiple stages with the required height on the top of the caisson (C), but the male keys (5a) (5b) (5c) (5d) are inserted into the female (6a) 6b (6c) (6d) Unit caissons and caissons are fixed in position, and these caissons are connected left and right along the quayside to form the required pier, filled with sandstone or high quality sand (9) inside the caisson, and a known concrete cap (10) at the top. The caisson docks will be constructed as a whole.

When the whole wharf is completed as above, it becomes a caisson-type upright wharf that is the most stable and solid wharf structure, but the existing caisson of huge size is laminated with several unit caissons to build the necessary pier height by stacking unit caissons. The super large crane is not required, so the construction is very easy and each unit caisson is up, down, left and right, respectively, with male keys 5, 5a, 5b, 5c, 5d and amchi 6, 6a, 6b. (6c) (6d) is formed and engaged with each other, so that the unit caisson can be provided by a caisson-type upright pier that is constructed in a more rigid structure without being separated by a horizontal external force or the like.
