Abstract
The utility model relates to a special protective tool used for guaranteeing the safety of underground operating personnel during the construction process of a manual hole digging concrete pile, in particular to an underground safety shield of a manual hole digging pile, which comprises a reinforced support frame and a protective cover plate. The cross section of the reinforced support frame is round and the round protective cover plate is mounted on an upper port of the reinforced support frame. The round protective cover plate comprises a fixed cover plate and a movable cover plate. The fixed cover plate is fixed on the upper port of the reinforced support frame, and the fixed cover plate and the movable cover plate are connected by a flange. The fixed cover plate and the movable cover plate are half round, made of wood plates with thickness of 50mm, and have light weight and good protection performance. The underground safety shield of the manual hole digging pile has a simple structure, is easy to process, is lower in cost, can be used for completely and effectively preventing people from being hurt by falling objects during the manual hole digging pile construction process and preventing events such as object falling and local collapsing during the well pile construction from hurting underground workers.
Description
Technical field
The utility model relates to a kind of special protection apparatus of in the manually digging hole filling pile work progress, guaranteeing the underground operators life security, specifically a kind of hand excavated pile downhole safety protective cover.
Background technology
Hand excavated pile is modal a kind of foundation structure type, and its degree of depth confirms that according to geological conditions shallow has only several meters, and dark reaches tens of meters.According to geological condition, generally can adopt concrete or steel retaining wall that supporting is carried out in the well stake, prevent to produce cave-in accident.But for the another one potential safety hazard---object hits does not but have the reliable precautionary measures.In present manual digging pile construction, generally all can build the walling crib more than the height 200mm by laying bricks or stones at well head, tumble in the well with the foreign material that prevent well head; Require underground operators to wear safety helmet simultaneously, prevent to be injured by a crashing object by foreign material.These ways are feasible in more shallow well pile driving construction; But work as the well stake degree of depth above ten meters; Its protective action is almost lost, and when malfunctioning or diameter drops greater than the stone of 50mm when the elevator facility that soil occurs hanging, must cause the injures and deaths of underground operators.
The utility model content
The technical problem that the utility model will solve provides a kind of simple, safety, is suitable for, reliable and be convenient to the hand excavated pile downhole safety protective cover of underground labour's constructing operation, protect operating personnel when underground work, can not injured by the object that falls in the high-altitude.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of hand excavated pile downhole safety protective cover comprises the reinforced bar support frame, protective cover plate; The cross section of reinforced bar support frame is circular, and the port of reinforced bar support frame is installed circular protective cover plate, and circular protective cover plate comprises securing cover plate and removable cover, and securing cover plate is fixed in the port of reinforced bar support frame, and hinge is connected securing cover plate with removable cover.
The operating principle of the utility model is that the reinforced bar support frame is supported on the well stake substratum, freely descends with digging depth.When the operator drop to fill sand in the hopper of down-hole after, the operator opened removable cover conveniently when hand steered hopper slowly rose to the height of protection cage; Pass through the reinforced bar support frame position of upper of hopper this moment after removable cover is opened; Stretch out one's hand the removable cover that closes subsequently.When hopper descended, the personnel in the pit opened the removable cover hopper of leaving behind and then closes again.Operating personnel are in the safe space from start to finish.
The utility model is simple in structure, handling ease, and cost is low, can avoid the junk in the manual digging pile construction process to hurt sb.'s feelings fully effectively, can reach the set goal.
The utility model special protection apparatus can be resisted incidents such as the object that takes place in the well pile driving construction falls, partial collapse the underground labour is damaged; The reinforced bar support frame has certain intensity, rigidity and bearing capacity, ensures for stranded workman provides security protection and the time of implementing rescue.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1-reinforced bar support frame, 2-lateral loops muscle, 3-circular protective cover plate, 301-removable cover, 302-securing cover plate, 4-arc handle, 5-hinge, 6-Protective small mesh net.
The specific embodiment
As shown in the figure: a kind of hand excavated pile downhole safety protective cover comprises reinforced bar support frame 1, circular protective cover plate 3; The cross section of reinforced bar support frame 1 is circular; The port of reinforced bar support frame 1 is installed circular protective cover plate 3; Circular protective cover plate 3 comprises securing cover plate 302 and removable cover 301, and securing cover plate 302 is fixed in the port of reinforced bar support frame 1, and hinge 5 is connected securing cover plate 302 with removable cover 301.Securing cover plate 302 is a large semi-circular, and removable cover 301 is that smaller part is circular, make with the plank that 50 mm are thick, and light weight, barrier propterty is good; Also can securing cover plate 302 and removable cover 301 all be made into semicircle; The stable circular support body that reinforced bar support frame 1 is made up of the reinforcing bar of four φ 22.Reinforced bar support frame 1 highly is 2 meters to 2.2 meters.Generally the height than the operator exceeds 300 to 500mm.
For enough assurance support strengths, reinforced bar support frame 1 top is established in four road φ, 18 reinforcing bars and is bound round as lateral loops muscle 2, and lateral loops muscle 2 spacings are 100mm; For making things convenient for digging, do not establish the lateral loops muscle in lateral loops muscle about 1.5m scope below 2.
Reinforced bar support frame 1 upper side is provided with highly roughly 500mm Protective small mesh net 6, and Protective small mesh net 6 can be wrapped in reinforced bar support frame 1 upper side with colour bar cloth; Can prevent that so the trickle sand and dust that drop from getting into operator's intraocular.
Arc handle 4 is housed below the removable cover 301; Before the workman goes into the well the utility model is put into well, the operating personnel opens removable cover 301 entering shaft bottoms, shuts removable cover 301 conveniently.After underground operators is filled hanging basket to soil, give signal of top operating personnel, and removable cover 301, treat to cover removable cover 301 more conveniently after hanging basket rises.
In work progress, because underground operators is under this protective frame with protective effect always,, also can be kept out by circular protective cover plate even there are foreign material such as stone to fall down, can not cause bottom operating personnel's actual bodily harm.
