Description
Technical Field
The utility model relates to a blasting flyrock protector can be used to close on engineering blasting operation fixed facilities safety protection.
Background
During engineering blasting operation, some fixed facilities are very close to a blasting point and inconvenient to remove, and the fixed facilities are very easy to damage under the impact of blasting flyrock, so effective protective measures are needed to be taken for protection.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple manufacture, simple to operate, safe and reliable saves construction cost's blasting flyrock protector who closes on blasting fixed facilities.
The purpose of the utility model is realized like this:
the utility model discloses blasting flyrock protector includes the sand bag that plays the cushioning effect to blasting flyrock, is located the bamboo springboard that sand bag both sides are used for fixed sand bag, is located the scaffold frame of the fixed sand bag in the sand bag outside and bamboo springboard, sets up respectively between foundation surface and structure and prevents the stock that the scaffold frame took place to topple under blasting flyrock strikes, and the sand bag is fixed with bamboo springboard and scaffold frame, plays the cushioning effect to blasting flyrock, prevents the blasting flyrock to fixed facilities's damage.
The scaffold comprises upright rods, longitudinal horizontal rods, transverse horizontal rods and cross braces, wherein the intersection positions of any two of the upright rods, the longitudinal horizontal rods, the transverse horizontal rods and the cross braces are connected by fasteners, and the whole scaffold plays a role in fixing sand bags.
The device of the utility model is simple in manufacture, simple to operate, safe and reliable saves construction cost. In actual construction, parameters such as the width, the diameter, the degree and the distance of the blasting flyrock protective device are properly adjusted according to the distance between the fixed facility and a blasting point, the blasting scale and the like, and the method can be widely applied to safety protection of various fixing facilities close to blasting operation.

Fig. 2 is the structural section schematic diagram of the blasting flyrock protective device of the utility model.
Fig. 3 is an enlarged view of a portion a in fig. 2.
Detailed Description
Referring to fig. 1-3, the utility model discloses blasting flyrock protector, include sand bag 1 to blasting flyrock play cushioning effect, be located sand bag both sides and be used for the bamboo springboard 2 of fixed sand bag, be located the sand bag outside and constitute the scaffold frame of fixed sand bag and bamboo springboard by pole setting 3, vertical horizon bar 4, horizontal horizon bar 5 and bridging 6. The crossing positions of any two of the vertical rod, the longitudinal horizontal rod, the transverse horizontal rod and the cross brace are connected by a fastener 8, and the whole sand bag fixing device has the function of fixing the sand bag. Anchor rods 7 are provided between the foundation surface 9 and the structure 10 to prevent the scaffolding from toppling under the impact of blasting flyrock.
The utility model discloses preparation, installation, application method as follows:
anchor rod and scaffold construction
Drilling an anchor rod hole manually by using an air leg drill, stirring mortar on site by using a forced stirrer, injecting the stirred mortar into the anchor rod hole by using a grouting machine, inserting an anchor rod, and building a scaffold after the mortar reaches the age. The scaffold is manually erected by scaffold steel pipes, and the nodes are connected by fasteners.
Bamboo springboard and sand bag installation
The bamboo gangplank is manually bound on the scaffold steel pipe by binding wires, fine sand is manually filled in the woven bag, and the bamboo gangplank is manually moved to the position between two layers of bamboo gangplanks and is orderly stacked.
Blasting flying stone removal prevention
After the blasting operation is finished, the sand bag is manually moved out, then the scaffold is dismantled from top to bottom, and finally the exposed anchor rods are cut off by oxygen acetylene.
