Mining under railways sealing off and covering anchorage skin hammer of the present invention vibrates method using a vibrating spear, which includes a barred body and skin Hammer, during the concrete perfusion into anchor slot, every perfusion 10~15cm concrete vibrating is primary, and is first carried out with barred body It vibrates, then guarantees concrete compaction to reach good effect of vibrating with skin hammering concrete surface, surfacing does not have There is bubble.

Detailed description of the invention

Fig. 1 is the construction schematic diagram that mining under railways sealing off and covering anchorage skin of the present invention hammers method of vibrating into shape;

Fig. 2 is the structural schematic diagram of vibrating spear of the present invention.

Specific embodiment

Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art referring to specification text Word can be implemented accordingly.

As depicted in figs. 1 and 2, the present invention provides a kind of mining under railways sealing off and covering anchorage skin hammer and vibrates method, comprising:

Step 1: in 1 surface built-in metal bellows of box beam anchor slot as filling concrete hole 2, the wavy metal The section of pipe is in down big up small trapezoidal;

Step 2: providing a vibrating spear, the vibrating spear includes barred body 3 and skin hammer, and the skin hammer includes a connecting sleeve 5 With a hammer body 6, the upper end of the hammer body 6 is connected to one end of spring 4, and the other end of the spring 4 is connected to the barred body 3 Middle part, the connecting sleeve are sheathed on the outside of the spring, the drift of the length of the connecting sleeve and the spring; By the filling concrete hole into the anchor slot concrete perfusion, and during concrete perfusion, every perfusion 10 ~15cm concrete vibrating is primary, and first the barred body is inserted into the concrete, the sustained vibration 30 in the concrete ~60s, then the barred body is taken out from the concrete, the vibrating spear is moved up and down, the hammer body is made to hammer institute repeatedly Concrete surface is stated, hammering continues 10~20s, until the anchor slot is filled up.

During sealing off and covering anchorage, by filling concrete hole into anchor slot concrete perfusion, and in filling process, every perfusion 10~15cm just vibrates once, when vibrating, barred body is first inserted into concrete, 30~60s of sustained vibration, then move up and down and vibrate Stick, makes hammer body hammer concrete surface repeatedly, and hammering continues 10~20s.By the above process, it is ensured that concrete compaction, Smooth surface, without bubble.

Skin hammer is connected to barred body by spring, and when moving up and down vibrating spear, spring stretches repeatedly, to make skin hammer hammering In concrete surface, this helps to improve the frequency of skin hammer hammering, and skin hammer more closes the dynamics of the hammering of concrete surface It is suitable, it is more advantageous to the defect for eliminating concrete surface, improves the compactness of concrete.Connecting sleeve can be to avoid excess compression bullet Spring guarantees the service life of spring.

Moreover, the section of metal bellows in down big up small trapezoidal, facilitate concrete in this way and passes through metal bellows It falls into and is deposited in anchor slot, especially in process of vibrating, concrete is relatively easy to deposit downwards under vibration auxiliary, thus Help to improve the compactness of concrete.

Preferably, the mining under railways sealing off and covering anchorage skin is hammered into shape in method of vibrating, in the step 2, in the mistake of concrete perfusion Cheng Zhong, every perfusion 10cm concrete vibrating are primary.

Preferably, during mining under railways sealing off and covering anchorage skin hammer vibrates method, in the step 2, first the vibrating spear is inserted Enter into the concrete, 30~60s of sustained vibration in the concrete, then the vibrating spear is taken from the concrete Out, the vibrating spear is moved up and down, the hammer body is made to hammer the concrete surface repeatedly, hammering continues 10~20s, until will The anchor slot fills up.

Preferably, the mining under railways sealing off and covering anchorage skin hammers method of vibrating into shape, further includes: Step 3: continuing to the concrete Concrete perfusion in fill orifice, every perfusion 5~8cm concrete vibrating is primary, and the vibrating spear is first inserted into the concrete In, the sustained vibration first time period in the concrete, then the vibrating spear is taken out from the concrete, it moves up and down The vibrating spear makes the hammer body hammer the concrete surface repeatedly, hammers and continues second time period, until by the coagulation Native fill orifice fills up;Also, from bottom to top, one layer concrete of every perfusion, the first time period increase 5s, second time Duan Zengjia 3s, after being filled with the first layer concrete, first time period 5s, second time period 3s.

Filling concrete hole is relatively narrow, and space is smaller, it is easier to lead to the problem of density and spend.Therefore, 5~8cm of every perfusion is just It vibrates primary, and rises with layer-by-layer, the time vibrated every time increase accordingly, i.e. time of vibration of the barred body in concrete increases Add, the time of skin hammer hammering also increases, this can guarantee that concrete is uniformly distributed, and guarantee filling concrete hole and anchor slot Junction will not be layered.

Preferably, the described mining under railways sealing off and covering anchorage skin hammer vibrates in method, in the step 3, the hammer body in a ring, The hammer body is set on the barred body, and the hammer body is connected to the barred body by multiple springs.

Annular hammer body can play better hammer effect, and then improve the efficiency and effect vibrated, and guarantee concrete dense It is real, it is durable.

Preferably, during mining under railways sealing off and covering anchorage skin hammer vibrates method, elasticity layer is arranged in the lower end surface of the hammer body 7, the elastic layer with a thickness of 2~3cm, the elastic layer is full of hole in the elastic rubber by being made of elastic rubber.

Elastic layer can be such that the hammer force degree of hammer body is reasonably distributed and uniform, reach good effect of vibrating.

Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited In specific details and legend shown and described herein.
