Detailed Description

The present application is described in further detail below with reference to the accompanying drawings.

The embodiment of the application discloses a flystone protector in a pile shaft blasting process, refer to fig. 1 and 2, including the guard plate 1 covered at the well head, the cross-sectional dimension of guard plate 1 is to be greater than the cross-sectional dimension of well head, the bottom of guard plate 1 has a plurality of springs 2 in tensile state through welded mode equipartition, and the one end that spring 2 kept away from guard plate 1 is connected with division board 3, division board 3's cross-sectional dimension is the same with division board 1's cross-sectional dimension, then through cover guard plate 1 and division board 3 together and establish in well head department, when having the flystone to splash towards the well head, division board 3 effectively intercepts the flystone, and buffer under the effect of spring 2 and reduce the impact, then avoid guard plate 1 to be lifted off, and after the impact of flystone is intercepted and buffered, still reducible noise that produces, be favorable to the surrounding living environment;

further because of job site environment complicacy, for convenient fixed in well head department with guard plate 1, still be connected with a plurality of pressure ropes 4 at the top of guard plate 1, pressure rope 4 both ends extend guard plate 1 and are connected with stock 5, stock 5 peg graft into subaerial, support through pressure rope 4 and press at guard plate 1 top then, then peg graft stock 5 into subaerial around the well head, effectively realize the fixed to guard plate 1, simple to operate, labour saving and time saving, and pressure rope 4 in this embodiment sets up along the protection diagonal symmetry for guard plate 1 atress is even, firm effectual, reduces the condition that lifts off.

Referring to fig. 2, in this embodiment, further in order to improve the protection effect on the flyrock, the bottom of the isolation board 3 is sequentially connected with the first isolation net 6 and the second isolation net 60 from top to bottom, the first isolation net 6 and the second isolation net 60 are both reinforced steel meshes formed by welding transverse ribs and longitudinal ribs, the mesh of the first isolation net 6 is smaller than the mesh of the second isolation net 60, then the second isolation net 60 is used for effectively blocking the flyrock with larger volume, the first isolation net 6 is used for isolating the flyrock with smaller volume, and the flyrock directly contacted with the isolation board 3 is effectively reduced, so that the flyrock directly falls into the well after being blocked layer by layer, even if larger blasting impact occurs, the protection board 1 is not directly lifted, and the structure is stable.

And the flyrock that contacts with division board 3 is also less flyrock, also effectively reduces division board 3 and appears the damaged condition to in this embodiment, still be connected with reinforcing plate 8 in the position that division board 3 bottom is located the centre, reinforcing plate 8's cross-sectional dimension is greater than the internal diameter of well head, receives the influence of well head size, and the flyrock mainly strikes division board 3 intermediate position, therefore, the middle part of division board 3 is comparatively weak, under reinforcing plate 8's effect, effectively prolongs division board 3's life.

Referring to fig. 1 and 2, in this embodiment, in order to reduce noise generated by flying stone impact, the baffle plates 7 are further connected to opposite sides of the protection plate 1 and the isolation plate 3, and the springs 2 are connected between the two baffle plates 7, so that a sound insulation channel is formed between the two baffle plates 7, and after larger noise is generated, the propagation of the noise is weakened gradually under the action of the double-layer baffle plates 7, thereby improving the surrounding living environment and protecting the environment.

Referring to fig. 1 and 2, in this embodiment, because the protection plate 1 is installed on the construction site, in order to facilitate storage, shipment and installation of the protection plate 1, the top of the protection plate 1 is detachably connected with the connecting rod 9, one end of the pressing rope 4 away from the anchor rod 5 is fixedly connected with the connecting rod 9, the pressing rope 4 is abutted to the top of the protection plate 1, then the pressing rope 4 and the anchor rod 5 can be detached from the protection plate 1 together in a detachable connection manner, and after the protection plate 1 is covered on a wellhead, the pressing rope 4 and the anchor rod 5 are connected with the protection plate 1, so that the structure is quite simple.

When the novel pressure rope is used, the threaded hole 90 is formed in the top of the protection plate 1, the connecting rod 9 is in threaded fit with the threaded hole 90, the pressure rope 4 and the anchor rod 5 are installed in a threaded connection mode, and the novel pressure rope is quite convenient and stable in structure.

Referring to fig. 1, in this embodiment, further in order to facilitate carrying of the protection plate 1, a handle 10 is further disposed on the protection plate 1 along a circumference thereof, so that the operation of a worker is facilitated by the handle 10, and a hanging ring 91 is further fixedly disposed on the top of the connecting rod 9, and since there are many hoisting devices or some excavating devices on the construction site, the carrying of the protection plate 1 can be realized by carrying the protection plate 1 by means of the hoisting and excavating devices in a lifting manner, and the operation intensity is effectively reduced.

The implementation principle of the flyrock protection device in the pile well blasting process is as follows: when the pile well is blasted, the protection plate 1 is positioned at the wellhead, the protection plate 1 is fixed through the pressing rope 4 and the anchor rod 5, the installation is convenient, the time and the labor are saved, when flying stones splash towards the wellhead, the flying stones with larger volume are blocked under the action of the second isolation net 60 and the first isolation net 6, then a part of flying stones with small volume impact the isolation plate 3, impact force is effectively reduced under the action of the spring 2, the situation that the protection plate 1 is lifted and flown is avoided, the noise is less in transmission, and the pile well is quite environment-friendly.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
