Description

Baffle that stone drops is prevented to pit shaft

Technical Field

The utility model relates to the technical field of municipal engineering construction, in particular to a baffle for preventing stones from falling off a shaft.

Background

The inspection well in the urban road range refers to various underground pipeline inspection wells, valve wells, operation wells, maintenance holes, water inlet openings and the like of paved water supply, rainwater, sewage, reclaimed water, electric power, communication, fuel gas, heat, street lamps, traffic signals and the like in the range including motor lanes, non-motor lanes, sidewalks, green belts, isolation belts and the like between buildings on two sides of the urban road.

After the construction of the well is completed, the well cover is installed at the well mouth position, and concrete, asphalt pavement and the like are poured. In the process of well lid construction, a large amount of building materials such as stones are required to be used, at the moment, the well lid is not installed, a shaft is in an open state, stones for construction can fall into the shaft, and the inside of the shaft is affected; the space in the shaft is smaller, and the later cleaning is inconvenient, so that the shaft needs to be protected in the construction process, and stones are prevented from falling into the shaft.

Disclosure of Invention

Aiming at the problem that stones and stones fall into a shaft in the well lid construction process, the utility model provides a shaft anti-stone falling baffle for preventing stones from falling into the shaft by blocking the shaft.

The utility model solves the technical problems by adopting the scheme that: the utility model provides a pit shaft prevents stone baffle that drops, includes bottom plate, umbrella face and umbrella vaulting pole, wherein is fixed with the base of connection usefulness on the bottom plate, and many umbrella vaulting poles are evenly installed in the outside of base, the umbrella vaulting pole be the elasticity vaulting pole, the umbrella face is installed on the umbrella vaulting pole, the outer end of umbrella vaulting pole surpasss the outward flange of bottom plate, the outer end of umbrella vaulting pole is provided with and colludes the ring, colludes to be connected with the stay cord on the ring, the stay cord is outside the pit shaft, the outer eaves outline size of umbrella vaulting pole is greater than the size of pit shaft.

Wherein, the outside of base evenly installs 8 umbrella vaulting poles, the stay cord has 4-8, evenly installs on corresponding umbrella vaulting pole.

The size of the bottom plate is the same as that of the shaft, and a flexible anti-skid pad is arranged at the edge position of the bottom plate.

The hard stay bars with certain length can be fixed on the outer side of the base, the hard stay bar arrays are distributed on the outer side of the base, and umbrella stay bars are fixed at the outer ends of the hard stay bars.

The utility model has the beneficial effects that:

according to the utility model, an umbrella support structure with the outline size of the outer eave slightly larger than the diameter of the shaft is adopted, the umbrella support structure is vertically arranged in the shaft, the edge of the umbrella support naturally warps under the action of elastic extrusion to form a bowl-shaped concave, the edge of the umbrella support is clung to the side wall of the shaft to shield the whole shaft, and sundries such as fallen stones fall into the shaft and can be directly collected on an umbrella cover which is supported by the umbrella support rod, so that the stones are prevented from falling into the shaft directly. After construction, pull the stay cord of connection on umbrella vaulting pole, the stay cord drives umbrella vaulting pole incurvate, and the outer eaves profile of umbrella vaulting pole reduces, and crooked radian increases, and the stone rolls down to umbrella vaulting pole center further, pulls out the stone on the umbrella face through the stay cord, has avoided the problem that the stone dropped in the pit shaft, ensures that the stone can not drop in the pit shaft, keeps the clean and tidy in the pit shaft, has avoided the trouble of later stage clearance pit shaft.

Detailed Description

The utility model will be further described with reference to the drawings and examples.

Example 1: in order to solve the problem that sundries such as stones fall into a shaft in the well lid construction process, the utility model provides a shaft stone falling prevention baffle shown in fig. 1-3, the baffle is transversely arranged in the shaft to form a shielding layer, the falling stones, stones and the like are directly collected on the baffle, the baffle and the sundries falling on the baffle are put forward together after construction is finished, and the stones are prevented from falling into the shaft.

The concrete structure is as shown in the figure, this pit shaft anti-stone baffle that drops includes the bottom plate 1 that is used for supporting and installs the umbrella face 2 and the umbrella vaulting pole 3 that are used for collecting the stone that drops on the bottom plate, set up a fixed base 11 that is used for connecting on bottom plate 1, be array form evenly fixed many umbrella vaulting poles 3 on the base, umbrella face 2 is made on umbrella vaulting pole 3, utilize umbrella vaulting pole 3 to prop up the umbrella face, the outer end of umbrella vaulting pole 3 forms circular profile, the size of this circular profile is greater than the diameter of pit shaft, set up simultaneously at the outer end of umbrella vaulting pole 3 and collude the ring, utilize collude ring connection stay cord 4, stay cord 4 is towards the well head of pit shaft, can pull out this baffle through pulling stay cord 4.

As shown in fig. 4, when in use, the baffle for preventing stones from falling from the shaft is vertically installed in the shaft, and the size of the upper umbrella stay 3 is slightly larger than the diameter of the shaft, so that the elastic umbrella stay 3 is upwards tilted under the extrusion of the side wall of the shaft, and the umbrella cover 2 supported by the umbrella stay 3 forms a concave arc shape and is in a bowl-shaped structure. The outer end part of the umbrella stay bar 3 can be clung to the side wall of the shaft, so that the shaft can be blocked.

The stay cord 4 is connected to the outer end of umbrella vaulting pole 3, and the length of stay cord is determined by the degree of depth of pit shaft, and stay cord 4 needs four at least to the stay cord 4 of connection need symmetry set up, keeps the baffle balanced when guaranteeing to pull out this baffle, prevents that the slope from leading to blocking the stone of collecting, stone to drop in the pit shaft. Meanwhile, after the baffle plate for preventing the stone from falling off the shaft is arranged in the shaft, the pull rope can be fixed on the side wall of the shaft or at the wellhead, and the pull rope is used for hanging and pulling the baffle plate to provide supporting force for the installation of the suspended baffle plate.

Further, the size of the bottom plate is the same as the size of the shaft, a flexible anti-slip pad is arranged at the edge position of the bottom plate, when the shaft anti-stone falling baffle is arranged, the bottom plate clamping sleeve is arranged in the shaft, the edge of the bottom plate and the inner wall of the shaft form a state of extrusion clamping sleeve, and the suspension supporting force of the baffle is provided by virtue of the friction force between the edge of the bottom plate and the shaft. The well lid construction is used all is little stone, and the size is little, and weight is limited, also has the template to restrict in the work progress simultaneously, avoids dropping of stone, consequently the pit shaft anti-stone baffle that drops only needs to prevent limited falling object, and weight can not be too big, relies on the unsettled installation of the friction between bottom plate and the pit shaft provided support force enough to satisfy pit shaft anti-stone baffle that drops to and the bearing of dropping stone.

The foregoing has outlined the basic principles, features, and advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model, which is defined by the appended claims.
