Description

Construction method of selecting the bottom (bottom) and the underwater asbestos using the release block mat and the lifting frame. {.}

The present invention relates to a construction method related to the selection of underwater bottom (bottom bottom) of the sea surface (floor bottom) and the underwater sandstone surface after dredging during the construction of structures in rivers and coasts such as Haman.

The construction methods up to now have been used by divers and foreigners who use underwater robots or underwater stoppers.However, divers use natural weather such as weather (air), algae (flow) and contrast (clear, cloudy). Due to climatic conditions, the number of working days decreased, excessive labor cost, air delay, and uncertainty of construction quality were confirmed.In case of underwater 'robot' or cutting-edge robot using high-tech equipment, Lack of adaptability, heavy expensive equipment purchase cost and future utilization rate are burdened.

In order to solve the defects described above, the present invention uses a commercially available 'cren', barge, and tugboat to mount a concrete release block mat to a lifting frame using the weight of the 'block mat' and the flatness of the bottom surface. In order to solve the desired construction by dragging from the bottom.

The present invention is intended to pick the sea floor by the flatness of the release block (w ⁰ 2. TON) to the screen 12 meth meth weight (24. ⁰ TON) and the ground area (20M ^2).

Blockmet binds the leading end and one row of trailing blocks to the lifting frame at an inclination of 45 ° to reduce the resistance of irregularities during the selection process, and the dragging and dragging wires connected to the lifting frame using 'cren' and tugboat. At this time, the unit block of 'Blockmet' is flexible, so the 'Met Hook Wire' reduces the impact and reduces the weight of each block even if the uneven surface of the bottom has a partial impact or resistance at the end of the block. It is possible to flatten the bottom uneven surface evenly.

Depth 5. ⁰ M-20. ^{The zero} draw method by tug is efficient and the depth within 5. ^O M is more efficient by dragging right and left by 'swing' of 'Cren'.

The invention leveling work by the submerged tank construction methods so far (standard pumsem calculating ^{1. 5 ~2. 0 M 2 /} hr) more efficient construction method of the present invention are more efficient as 30M ² / hr water stations 'robot' Compared to the way of using underwater doja, the commonly used 'cren', barge, and tugboat can be used to reduce the burden of expensive underwater equipment purchase and economical and efficient construction is possible.

Based on the accompanying drawings of the present invention described above --------

1 is a perspective view of the assembly of the block and the lifting frame of the present invention, Figure 2 is a side view of the use state of Figure 1 and Figure 3 is an embodiment of applying the present invention to the bottom (bottom) level and Figure 4 Another embodiment of the present invention is applied to the selection of underwater asbestos.

Reference numeral (1) is a lifting frame, which is formed by assembling 12 release blocks (2) and (2 ') with connecting rings on four sides, and lifting them with a' met hook wire '(1'). 1) and can be inserted into the cran (7) and the bottom (8) of the medallion working position with the 'cran hanger wire' (3) and 'cran wire' (3 '). 'Wire' (4 ') is dragged onto the tugboat (5) by dragging the wire (4') bound to the release block mat (2) (2 ') and the lifting frame (1).

At this time, the unevenness of the sea bottom (bottom) 8 is selected by the block 2 'and the flat bottom surface of the entire block block' 45 'and the release block mat 2 and the block 45 °. (2 ') are each assembled with' U bolt 'in the connecting ring, and the hanging frame (1) is suspended by the' met hanger wire 'so that the bottom surface (bottom) (8) is irregular or struggling (9) It is also possible to reduce the shock and resistance of bumps and bumps on the front end of the block mat, and to select the bottom (8) and the bottom of the stone (9) through the release block drag method. By shifting the position to the cran (7) and repeat the drag operation will be able to easily perform the underwater stop operation and the selection operation.

Unexplained reference numeral 10 is a stone seat 11, buoy 12 is sea level.

The present invention solves the low efficiency of the existing method of underwater selection by the submersible and the reduction factor of the actual working days due to weather (wind), algae (flow), contrast (clear, cloudy) and the expensive equipment underwater 'robot', underwater To achieve technical and economic effects by developing a method with efficiency that surpasses the construction ability of Doja.

In general, the present invention can be carried out by 'cren', tugboat, barge, which are commonly used in the field, and can control the weight and the plane of the 'block mat' according to the site conditions. 5. Below ⁰ M, the method of dragging left and right by 'swing' of 'cren' is easy. For example, the result of selecting by using 'cren' and tugboat together in the arrangement of Sasatutu,

1. ⁵ to 2 per hour of diving tank. ⁰ M ² working capacity was standing up, so the efficiency of 30M ² per the invention increases the efficiency of a 15-fold compared to the (standard construction pumsem) to obtain a cost savings of 70%.

The present invention, which can solve low efficiency without putting manpower into dangerous underwater work, can avoid the purchase of expensive underwater equipment with a low frequency of use, thereby reducing the burden on construction companies and having the construction efficiency and economic efficiency to utilize commercial equipment. It is a very useful invention.
