technical field

The invention relates to an urban-rural integrated floating net building group.

Background technique

The overall layout of the current urban buildings has blocks, belts, rings, series, clusters, constellations, nets, etc., but in fact their common feature is still a densely populated urban area composed of dense buildings. Some scattered building groups form sparsely populated villages, among which railways, highways, rural water conservancy, urban industrial and domestic water supply, sewage treatment, and public facilities such as gas, electricity, communications, culture, entertainment, and transportation take up a lot of land, It consumes a huge amount of people and property, but there are still dead ends in services. Overcrowded urban areas are difficult to overcome traffic congestion. In earthquakes, floods, typhoons, tsunamis and other disasters, dense populations are difficult to evacuate quickly and are vulnerable to greater damage. Overpopulation Sparse rural areas make it difficult to provide rural areas with the same public services as urban ones due to the increased cost of public facilities due to scattered distribution. Existing rural water conservancy projects are also difficult to increase the area of irrigated fields, which limits agricultural production. Urban roads and The construction of underground pipelines requires repeated excavation of the ground, which affects normal production and living order. Existing water, electricity, gas and other pipelines are mostly in the form of branches, and service interruption during fault maintenance will have a large impact and take a long time. Implementation of urban However, it is difficult to avoid the above-mentioned problems, because this is not just a simple problem of population gathering, but also a problem of the layout and structure of all industrial and agricultural public service facilities, that is, the lack of high investment efficiency The disadvantages caused by the urban-rural integrated building complex structure urgently need to be solved to eliminate the subsequent huge amount of human and property consumption on such unsatisfactory public facilities, so that it can benefit the people more.

As for the horizontal fluctuations caused by storms, huge waves, and strong earthquakes, the larger free flow of water between the floating bridge 4 and the bottom of the waterway 1 The large inertia pontoon bridge 4 only produces a small horizontal shift, thereby reducing or even eliminating the damage to the tunnel 3 and the passing maglev vehicle.

As shown in Figures 3 and 4, a water tank 7 is provided at the bottom of the buoyant tank 6 so as to correct the draft height difference of the buoyant tank 6 by changing the water level in the water tank 7 .

As shown in Figure 3, the minimum depth and width of the waterway 1 where the upper floor pontoon bridge 21 and the middle floor pontoon bridge 22 are located will ensure that the pontoon bridge 4 covered with the tunnel 3 under the local maximum tide and earthquake action will not touch the bottom and touch the bank, but the lower floor pontoon bridge 23, The base pontoon 24 allows the damping pad 20 made of various flexible or elastic materials including silt, straw, bamboo and wood components, aquatic plants and the water body surrounded therein to touch the bottom of the waterway 1 or the bank during a strong earthquake. .

As shown in Figures 3 and 4, some joints between the longitudinal members 13 and the transverse members 14 of the pontoon 4 are connected with expansion joints 9 to eliminate the length change of the pontoon 4 caused by thermal expansion and contraction.

As shown in Fig. 6, the telescoping joint 9 includes flanges 15 made on the two ends of the longitudinal member 13 that protrude outwards or are drawn inwards or the flange 15 of the abdominal hole of the transverse member 14, and the joints fixed on a member Assemblies 16, the thrust fluid bladder 17 clamped in the gap between the flanges 15 on the two components to be connected, the tension fluid bladder 18 attached to the gap between the other side of the flange 15 and the connecting component 16, communicating the thrust The throttling device 33 of the liquid bag 17 and the pulling force liquid bag 18 eliminates the slow temperature change of the floating bridge 4 by the controlled liquid flow between the thrust liquid bag 17 and the pulling force liquid bag 18, and at the same time makes the expansion joint 9 work in wind, waves, Under the sudden impact of tides and earthquakes, the required rigidity is still maintained for a long enough time to limit the deformation of the floating bridge 4 within a safe range, so as to gain time for emergency deceleration parking and reversing of vehicles in the floating bridge 4 .

All the above-mentioned components are not all required to be equally available in all regions, but are more or less configured or even omitted according to geographical and climatic conditions according to local conditions; And pontoon bridge 4 earthquake-resistant cost, suppression of typhoon raging intensity, increase production and living space, and connect the continents of the world to improve economic integration.

Apparently, the present invention can make the urban and rural building groups be continuously distributed in a narrow strip along the traffic route, and make the buildings on each pontoon bridge arrange in parallel with pipelines such as traffic, water, gas, electric power, communication, etc., thereby greatly reducing the consumption of passenger and cargo transportation. Timely and reduce transportation costs, shorten the length of public pipelines, achieve lower construction costs, provide equal levels of public services to integrated cities and villages, and reduce potential safety hazards caused by natural disasters such as earthquakes. It is a high-efficiency urban-rural integration It can solve the various disadvantages caused by the shortage of this structure.
