Description
Technical field
The present invention relates to the mud-rock flow field of blocking, particularly relate to mud-rock flow that a kind of anti-megalith the impacts structure of blocking.
Background technology
In the past, anti-Zhiduo County of mud-rock flow was adopted to the gravity entity dam of blocking.The block way on dam of gravity entity can adopt free stone masonry, also can adopt plain concrete or steel concrete to build and form, and this kind of method mainly relies on the deadweight on the dam of blocking and the impact force that rigidity is carried out mud-rock flow.In < < disaster prevention engineering design standard > >, the gravity entity dam of blocking is had a detailed description.
The gravity entity dam shortcoming of blocking is: (1) opposing megalith impact capacity is poor; (2) energy-dissipating property is poor; (3) from great; (4) fragile with the direct contact position of megalith.The present invention is based on power consumption and protection integrated thought, propose spring lattice mud-rock flow that a kind of anti-megalith the impacts structure of blocking.
Summary of the invention
The object of this invention is to provide spring lattice mud-rock flow that a kind of anti-megalith the impacts structure of blocking.
the present invention isthe spring lattice mud-rock flow that anti-megalith the impacts structure of blocking, comprises connected node 5, the spring lattice mud-rock flow that anti-megalith the impacts anterior plane groined type structure forming for I shape steel column 1 and i-shape steel beam 2 of the fluoran stream surface of structure of blocking; Anterior I shape steel column 1 and i-shape steel beam 2 and rear portion are that the fluoran stream surface of steel concrete dam body 6 is parallel; Groined type bean column node place arranges spring 3, and spring 3 is perpendicular to the fluoran stream surface of the steel concrete dam body 6 at anterior groined type structural plan and rear portion; Groined type bean column node place arranges spring protecting jacket 4, spring protecting jacket 4 is for coordinating the round steel pipe of spring diameter, the pre-buried spring protecting jacket 4 in fluoran stream surface relevant position of corresponding steel concrete dam body 6, spring 3 two ends are placed in the spring protecting jacket 4 of groined type bean column node place and steel concrete dam body 6; The lower end of I shape steel column 1 is fixed on the basis of steel concrete dam body 6.
The invention has the beneficial effects as follows: by the improvement on dam that original gravity is blocked, in dam body fluoran stream surface front portion, groined type steelframe and spring are set, while blocking dam when megalith impacts, first contact anterior groined type steelframe, Compress Spring after anterior steelframe deforms, thereby consumed the part energy of megalith, played certain cushioning effect, and the single-point concentrated force of megalith is converted to multiple spot concentrated force by anterior steelframe and spring distributional effects, and reduced the size of impulse force, avoided the direct impact of megalith to rear portion concrete dam body, improved the ability that the anti-megalith of dam body impacts, overcome the gravity mud-rock flow dam of blocking and be subject to megalith and impact easily damaged shortcoming, owing to having improved the ability that the anti-megalith of dam body impacts, can suitably reduce the concrete amount of rear portion dam body, the safety that has improved dam body, technology is simple, is convenient to application.
Accompanying drawing explanation
Fig. 1 is the elevation of structure of the present invention, and Fig. 2 is the sectional side view in Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As shown in Figure 1 and Figure 2, the present invention is spring lattice mud-rock flow that a kind of anti-megalith the impacts structure of blocking, comprise connected node 5, the spring lattice mud-rock flow that anti-megalith the impacts anterior plane groined type structure forming for I shape steel column 1 and i-shape steel beam 2 of the fluoran stream surface of structure of blocking; Anterior I shape steel column 1 and i-shape steel beam 2 and rear portion are that the fluoran stream surface of steel concrete dam body 6 is parallel; Groined type bean column node place arranges spring 3, and spring 3 is perpendicular to the fluoran stream surface of the steel concrete dam body 6 at anterior groined type structural plan and rear portion; Groined type bean column node place arranges spring protecting jacket 4, spring protecting jacket 4 is for coordinating the round steel pipe of spring diameter, the pre-buried spring protecting jacket 4 in fluoran stream surface relevant position of corresponding steel concrete dam body 6, spring 3 two ends are placed in the spring protecting jacket 4 of groined type bean column node place and steel concrete dam body 6; The lower end of I shape steel column 1 is fixed on the basis of steel concrete dam body 6.
The plane groined type structure that described I shape steel column 1 and i-shape steel beam 2 form only has lower end to fix, and the left and right sides and upper end are all unfixing.
Anterior I shape steel column 1 is parallel with the fluoran stream surface of the steel concrete dam body 6 at rear portion with i-shape steel beam 2.
The above is only optimal way of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
