Description
Technical field
The present invention relates to bridge-collision-avoidance technical field, particularly relate to a kind of bridge-collision-avoidance energy dissipating anchor heavy stone used as an anchor.
Background technology
During conventional bridge-collision-avoidance designs, without the interception crashproof form of system this kind, bridge protection domain is less, in order to expand bridge protection domain, create interception this kind of novel crashproof system. Buoyancy aid generally all needs to be tied up in water by firm earth anchor, just considering to remove after completing its usage period, the mooring system of employing is more stable, but bridge is used interception system, then wish that it is without energy stable position during crash, can play energy dissipating effect when there being crash. If Impact energy is consumed (rigidity is crashproof) by the tension force of the location anchor chain and interception anchor chain that form interception system completely, then anchor chain type selecting can be very big, and corresponding auxiliary facility is also very big, causes cost higher, also makes troubles to construction. Therefore when ship hits, it is desirable to the mooring system of interception system drags of anchor, and can make to be hit buoyancy aid and produce suitable displacement, to reach the object of energy dissipating gradually.
Conventional location anchor has iron anchor. Iron anchor is being weighed anchor in the situation of angle, anchor holding power loss is bigger, when being embedded in soil, it does not have enough weigh anchor angle and uplift forces, it is very difficult to be unearthed, and for anticollision energy eliminating, wish that anchor is when being buried by silt, can under impact force effect, it is easy to be unearthed, and can continue energy dissipating under frictional force effect after being unearthed, therefore iron anchor cannot meet the demand of crashproof interception system.
Summary of the invention
Based on this, for above-mentioned technical problem, it is provided that a kind of bridge-collision-avoidance energy dissipating anchor heavy stone used as an anchor.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:

Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the anchor heavy stone used as an anchor block structural representation of the present invention.
Fig. 3 is the structural representation of the anchor heavy stone used as an anchor block body of the present invention.
Embodiment
As shown in Figure 1, a kind of bridge-collision-avoidance energy dissipating anchor heavy stone used as an anchor, comprises multiple anchor heavy stone used as an anchor block 1100 and anchor chain 1200, and multiple anchor heavy stone used as an anchor block 1100 is by anchor chain 1200 head and the tail series connection.
During use, can the anchor heavy stone used as an anchor block 1100 of multiple little quality all drop to the ground setting, and be buried in the earth, anchor heavy stone used as an anchor block 1100 is being embedded in Tu Zhongqian, its " anchor holding power " is frictional force, after being embedded in soil, its " anchor holding power " is earth pressure and frictional force sum, without clash into time can be stable be positioned in soil, total " anchor holding power " that the anchor heavy stone used as an anchor block 1100 of series connection produces, environmental load before can balancing shock, maintain the balance of intercepting system, single anchor heavy stone used as an anchor block 1100 is when clashing into, led pull-out soil one by one, then dragged by entirety, anchor heavy stone used as an anchor block 1100 is unearthed one by one and trailing process is the process of energy dissipating, the effect of flexible protection can be played.
Anchor heavy stone used as an anchor block 1100 comprises anchor heavy stone used as an anchor block body 1110 and anchor pole 1120.
Specifically, such as Fig. 2 and as shown in Figure 3, anchor heavy stone used as an anchor block body 1110 is in terrace with edge shape, and its end face is little, bottom surface big, and close to taper, when buoyancy aid is subject to clashing into, anchor heavy stone used as an anchor block body 1110 can be unearthed smoothly.
Herein, anchor heavy stone used as an anchor block body 1110 is designed to the truncated rectangular pyramids (5 tons belong to little quality in this area) of 5 tons of weights, and its rib and base are 77 �� of angles, and its end face is the square of the length of side 0.6 meter, and bottom surface is the square of the length of side 1.5 meters, and height is 2 meters.
Certainly, anchor heavy stone used as an anchor block body 1110 can also be many terrace with edges shapes such as three terrace with edges, five terrace with edges or six terrace with edges.
Anchor heavy stone used as an anchor block body 1110 can be concrete blocks, in order to prevent anchor pole 1120 slippage, is provided with Framework Of Steel Reinforcement in anchor heavy stone used as an anchor block body 1110, and anchor pole 1120 and Framework Of Steel Reinforcement are fixed.
Such as Fig. 2 and as shown in Figure 3, thin middle part, anchor pole 1120 two ends is thick, it is arranged in anchor heavy stone used as an anchor block body 1110, and the medullary ray of anchor pole 1120 and anchor heavy stone used as an anchor block body 1110 coincides, middle part is positioned at anchor heavy stone used as an anchor block body 1110, both ends are all exposed to outside anchor heavy stone used as an anchor block body 1110, and namely the head end of anchor pole 1120 is exposed to outside the end face of anchor heavy stone used as an anchor block body 1110, and tail end is exposed to outside the bottom surface of anchor heavy stone used as an anchor block body 1110.
Wherein, anchor pole 1120 can ensure that the anchor heavy stone used as an anchor block body 1110 of one or more anchor heavy stone used as an anchor block 1100 damages other anchor heavy stone used as an anchor blocks 1100 rear and connects all the time, and anchor pole 1120 can adopt anchor chain steel to make, and its intensity is at least suitable with connected anchor chain.
As shown in Figure 1, the head end of the anchor pole 1120 on first anchor heavy stone used as an anchor block be used for bridge-collision-avoidance energy dissipating with buoyancy aid be connected.
As shown in Figure 1, the two ends of each anchor chain 1200 are connected with anchor pole 1200 end on the anchor heavy stone used as an anchor block 1100 before and after it respectively.
Specifically, the two ends of anchor chain 1200 are fixed with shackle 1220 indirectly by change 1210, and anchor chain 1200 is connected with the end of the anchor pole 1120 of anchor heavy stone used as an anchor block 1100 by shackle 1220.
As shown in Figure 1, change 1210 is arranged between two intermediate links 1230, and revolving cup 1210 is indirectly connected with shackle 1220 through an intermediate link 1230 and a common link 1240.
In addition, the head end of the anchor pole 1120 on first anchor heavy stone used as an anchor block can also be connected with buoyancy aid by the anchor chain 1200 of as above structure, namely, in multiple little quality anchor heavy stone used as an anchor block 1100, the head end of the anchor pole 1120 of first anchor heavy stone used as an anchor block 1100 is connected with buoyancy aid by shackle 1220, change 1210, intermediate link 1230 and common link 1240.
The setting of change 1210 is possible to prevent anchor chain 1200 and produces kink, meanwhile, the setting party of shackle 1220 the connection of multiple anchor heavy stone used as an anchor block 1100 and fractionation.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and not it is used as limitation of the invention, as long as in the spirit of the present invention, to the change of the above embodiment, modification all by the Claims scope dropping on the present invention.
