Tethered isolation and floating floating foundation system and its construction method

The technical field to which the present invention pertains: the construction method of the isolated and isolated floating foundation system, in particular, is completed in the factory as shown in Figures 20, 21, and 22 with steel bars, stencils, and water-insulating foam materials (21, also serving as internal molds). And various types of floating base unit modules (25W0S0 to 25W2S2, referred to as unit modules), bollards (22) and side mold side supports (24) composed of the upper assembly (23a) of the elastic isolation movable support All types of unit modules can be transported to flood-prone areas by existing vehicles and roads for assembly into a complete floating foundation module (referred to as a floating base module) and after reinforcing the sideform side braces and assembling the top plate reinforcement, only The floating foundation of the required volume can be completed by pouring the watertight concrete on site; then the bollard (4) and the installation buoy (5) are buried on the site to connect the tether (16) with the floating foundation bollard (22). The construction method of the entire tethered and isolated floating foundation system; to greatly simplify the on-site construction work of the floating foundation and solve the difficulty that the traditional large-volume floating foundation cannot be transported from land to flood-prone areas.

Prior art related to the present invention:

1. The traditional floating foundation is shaken horizontally when it encounters an earthquake. When the local surface moving direction (17) is to the left as shown in Fig. 1(a), the traditional floating foundation (1) moves in the direction due to the inertial force. Right (18), the traditional floating foundation, the bollard frame (14) and the traditional bollar (13) will collide with each other; when the local plane moves in the opposite direction, it will make the traditional floating foundation, the bollard frame and the traditional bollar Being pulled, such reciprocating action will damage the bobbin frame (14) and detach it, so when flooded, it will cause the traditional floating foundation (1) to have four drifts and collide as shown in (a1) of Fig. 1 The danger of destruction.

2. When the traditional floating foundation vibrates vertically up and down in the event of an earthquake, as shown in Figure 1 (b), when the local surface moving direction (17) is upward, the traditional floating foundation (1) moves downward due to the inertial force. (18), the traditional floating foundation (1) and the ground will collide with each other. The traditional floating foundation will collide with the ground and cause the floating base plate and the outer wall to be damaged. Therefore, when flooded, it will be as shown in Figure 1 (b1). The infiltration of water into the traditional floating foundation (1) via the damage can result in the risk of the sinking of the floating foundation sinking.

3. The traditional floating foundation (1) is fixed as shown in Figure 1 (c) with the tether (16) directly connected to the traditional anchor (15) under the ground. When the flooding is high, it will be as 1 (c1) shows that the traditional anchor foundation (15) is deep under the water surface, which will tilt the traditional floating foundation (1). When the water flow rate is large, the floating foundation may be overturned and sunk.

4. The traditional floating foundation is bulky at the water's edge or in the dock, and then towed by the waterway to the mooring anchor. However, this method cannot be used for land-based flooded areas due to its large size and cannot be transported by land. It is flood-proof, so the bulky floating foundation in the inland flooded area can only be manufactured on site; but the large floating foundation needs to be bent at the site according to the order of the bottom plate, the wall body and the top plate. The group is demolished, other supporting members are installed, and then the concrete is poured in accordance with the sequence to complete the application of the floating foundation. Therefore, the construction work is complicated and takes a long time.

The content of the invention:

1. The present invention is a mooring-isolated floating base system and a construction method thereof. The system has a partition wall (2c) and a water-repellent foam material (21) under the bottom plate as shown in Figures 7 and 40. The watertight reinforced concrete isolated floating foundation (2) of the seismic isolation support (23a) is placed on the ground support basic plate (3) with the movable support lower steel raft (23b1), and then on the floating foundation The bollard (22) is a tethered floating base system connected by a tether (16) and a buoy (5) passing through the bollard (4); the floating foundation and the tethered system are protected from damage during an earthquake. When the water rises above the ground, even if it is hit by drifting wood or floating objects, it can safely float on the fixed-seismic floating base system in the fixed area of the water.

2. The construction method of the system for seismic isolation and floating foundation system is completed in the factory as shown in Figures 20, 21 and 22 with steel bars, stencils, protective layer blocks, water-tight foaming materials (21) and elastic partitions. Each of the floating base unit modules (25W0S0 to 25W2S2, referred to as a unit module) composed of the upper assembly (23a) of the seismic activity support; and the bollard (22) shown in Figures 10 and 15 is completed in the factory, Float (5), The column (4) and the side mold side support (24) and other components; and after the completion of the ground basic version (3) on the site as shown in Figures 30, 33 and 37, the various unit modules are combined on the basic plate, and After the unit modules strengthen the side mold side braces (24) and form the floating foundation top plate steel bars (2a1), the watertight concrete is poured on site to complete the reinforced concrete isolation floating foundation (2); as shown in Figures 39 and 40 The installation of the bollard (4) and the installation of the buoy (5) and the tether (16) are carried out on site to complete the construction of the entire tethered isolation and floating foundation system.

1. At present, the traditional floating foundation is subjected to an earthquake and the floating foundation is horizontally vibrated by the inertial force. The traditional floating foundation (1) shown in Figure 1 (a) will be combined with the traditional bobbin beam frame (14). The traditional bollards (13) collide and pull each other, causing the traditional bobbin bundle frame (14) to be damaged and detached. Therefore, when flooding, the traditional floating foundation (1) is drifted as shown in (a1) of Fig. 1 Risk of being hit by falling trees or floating objects.

2. The traditional floating foundation is subjected to an earthquake and the floating foundation is vertically vibrated up and down due to the inertial force. As shown in Fig. 1(b), the traditional floating foundation (1) will collide with the ground, which will result in the traditional floating foundation and the outer layer. The wall is damaged, so when flooded, as shown in Figure 1 (b1), water will seep into the traditional floating foundation through the damage, which will cause the floating foundation to tilt to the danger of sinking.

3. The other traditional floating foundation (1) is fixed as shown in Figure 1 (c) with the tether (16) directly connected to the traditional anchor (15) under the ground. When the flooding is very high, as shown in Figure 1. The (c1) shows that the traditional anchor foundation (15) is deep under the water surface, and the traditional floating foundation is inclined. When the water flow rate is large, the floating foundation may be overwhelmed.

4. The traditional floating foundation is bulky at the water's edge or in the dock, and then towed by the waterway to the mooring anchor. However, this method cannot be used for land-based flooded areas due to its large size and cannot be transported by land. Flood prevention. Therefore, the large floating base in the inland waters of the flood-prone area can only be manufactured on site due to the inability of land-based transportation; however, the large-scale floating foundation needs to be bent at the site according to the order of the bottom plate, the wall body and the top plate. Reinforcement, group demoulding, installation of other matching components and pouring concrete to complete the construction of the floating foundation, so the construction work is complicated and takes a long time.

1. The tethered floating base of the present invention (2) has a resilient isolation movable support upper assembly (23a, including a bottom Teflon plate) at the bottom as shown in Figures 7 and 9, and the floating foundation is placed to contain activities. Supporting the ground support plate (3) of the lower steel shovel (23b1, top surface containing Teflon plate), when the floating foundation and the ground move horizontally relative to each other during the earthquake, the upper part of the floating base supports the upper part The low friction between the (23a) and the ground-based version (3) of the Teflon plate will cause the floating foundation to slide on the ground basic plate without being damaged by the horizontal force of the earthquake; when the floating foundation is used (16) After connecting the bollard (22) and the float (5) on the bollard (4) at a considerable distance from the floating foundation to form a mooring system, the floating foundation can be subjected to an earthquake and the tethering system does not The impact is damaged, so when the water rises above the ground, as shown in Figure 5, it can safely float on the fixed surface of the water without drifting around to cause the danger of collision.

2. The tethered floating base of the present invention (2) as shown in Figures 7 and 9 has an elastic isolation movable support upper assembly (23a, rubber bearing pad (23a5)). When there is vertical relative movement, the rubber support pad can absorb the energy of the vertical vibration, so that the floating foundation does not damage the bottom plate and the outer wall due to the vertical force of the earthquake. Therefore, when the water floods above the ground, the above-mentioned mooring system can naturally float safely on the water fixed range as shown in Fig. 5 without drifting around to cause the danger of being destroyed.

3. The tethered floating base of the present invention (2) is shown in Figures 6 and 7 because of the partition wall (2c), which partitions the interior of the floating foundation into a plurality of independent inner compartments, and the space of the inner compartment Filled with the water-insulating foaming material (21), when the floating foundation is floating, even if the outer wall or the bottom plate is damaged by the impact of the drifting wood or floating objects, the water seepage cannot enter the space inside the floating foundation and remain floating. The original buoyancy of the foundation allows the floating foundation to float safely on the surface without sinking.

4. The present invention, as shown in Figures 7 and 40, is provided by a bollard (22) on a floating foundation and a bollard (4) at a considerable distance from the floating foundation and a tumbler (5) passing therethrough to tie the tether (16) Connected to form a mooring system; as shown in Figure 5, the buoy (5) floats up and down the water along the bollard (4) when flooded, so when the flooding is higher than the ground, the float is connected via the buoy (5) The tether (16) of the foundation (2) and the bollar (4) can still be level with the water surface, so that when the water flow rate is large, the floating foundation is not caught by the inclined tether and is overturned.

5. The construction method of the tethered floating floating foundation system of the present invention is to solve the problem that the large-volume floating foundation of the factory cannot be transported by land and the large-volume floating foundation is manufactured on site, because the on-site construction work is complicated. The problem that takes a long time is as follows:

A tethered floating base of the required volume can be completed. According to the combination of the unit modules shown in Figures 24 and 25, in addition to the floating base of the smaller volume of 2 rows X2 columns and 2 rows X3 columns, if the number of unit modules shown in Figure 26 is more than this The number of unit modules is more. The combination unit module can complete 5 rows X5 columns or larger. Floating foundation, which can greatly simplify the construction work of large-volume floating foundation on-site manufacturing and shorten the construction time, and solve the problem that the traditional large-volume floating foundation can only be towed by the waterway after completion of the waterside or dock. It is difficult to transport from land to flooded land areas.

d. Finally, the installation of the bollar (4) and the installation of the buoy (5) are carried out at the site as in Figures 39 and 40, and the tether (16) is attached to the bollard (22) of the floating foundation to complete the floating tether.
