Description
Technical Field
The utility model is used for the safety protection cover plate of the deep foundation pit opening in the foundation construction of the power transmission iron tower, and can also be used for the safety protection cover of the deep foundation pit opening in other capital construction projects.
Background
In recent years, with the big environment of energy saving and clean energy development advocated by the nation, novel energy generation such as solar power generation and wind power generation is very important, and the method also accords with the energy development plan of carbon peak reaching and carbon neutralization vigorously advocated by China. The AC/DC (ultra) high-voltage transmission line is a carrier for carrying electric energy, the AC/DC (ultra) high-voltage transmission line needs to pass through a plurality of mountains and unmanned areas, the foundation design of the transmission line tower is mostly deep foundation pits within phi 1.8m of more than 10 meters, and a pit opening needs to be additionally provided with a cover plate in order to ensure the safety and environmental protection requirements of personnel in a construction site.
The traditional cover plate is covered by a simple iron plate, is thick and heavy, and is inconvenient to transport in the up-and-down transportation and construction processes; the cover sealing mode easily causes safety accidents such as slipping and falling injury of constructors in rainy and snowy days; meanwhile, a closed space is formed after the cover is covered to the pithead, harmful gas accumulation is easy to cause, and safety production accidents such as poisoning and suffocation are easy to occur due to improper operation. Therefore, a safety protection cover plate for the deep foundation pit opening is urgently needed to solve the problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems of effectively and reliably protecting the deep foundation pit opening, reducing the accumulation of toxic and harmful gases in the foundation pit, preventing constructors and wild animals from falling into the foundation pit, protecting the deep foundation pit opening from collapse within 1m and facilitating the transportation of deep foundation pit opening protection facilities and materials.
In order to solve the technical problem, the utility model provides a safety protection cover plate for a deep foundation pit opening in power transmission iron tower foundation construction, which is characterized in that: including the top cap framework, the grid board, protective case installs in shaft tower foundation ditch mouth, the top cap framework is installed above foundation ditch mouth, protective case passes through the bolt with the top cap framework and articulates, the grid board is spread above the top cap framework, it has the round hole to open on the grid board, the circular grid board that matches with the round hole is inlayed in round hole department, circular grid board is divided into two at diameter department and is become two semi-circular grid boards, two semi-circular grid boards are connected and can be smoothly this round hole of closing cap through folding paper in diameter department.
Furthermore, the edges of the two semicircular grating plates are provided with opening handles, so that the opening is convenient.
Further, the top cover framework is installed on the side wall of the foundation pit of the tower through the ground anchor rod.
According to the utility model, the protective sleeve is arranged at the foundation pit opening, so that the periphery of the foundation pit opening is effectively protected, and collapse of the pit opening is prevented; the grid plates above the top cover framework connected with the protective sleeve are provided with round holes, the round grid plates embedded in the round holes are divided into two semicircular grid plates at the diameter positions, and the two semicircular grid plates are connected at the diameter positions through hinges, so that the deep foundation pit opening protective device and the material can be conveniently transported, the round holes can be smoothly sealed, and constructors and wild animals can be prevented from falling into the foundation pit; meanwhile, the cover plate is not sealed with the pithead, so that harmful gas is favorably dispersed, and safety production accidents such as poisoning and suffocation are avoided.

FIG. 2 is a plan view of the present invention;
fig. 3 is a schematic view showing the installation relationship of the grating plate and the circular grating plate of the present invention.
Detailed Description
Referring to fig. 1 to 3, the concrete embodiment of the utility model includes a top cover framework 1, a circular grid plate 2, a protective sleeve 5, a grid plate 6 and a ground anchor rod 8, wherein the top cover framework 1 is formed by welding galvanized square pipes with the wall thickness of 60x100mm not less than 5mm, the steel galvanized grid plate 6 with the thickness of 5mm is fully paved on the top surface of the top cover framework 1, and the size of a cover plate depends on the size of a deep foundation pit and is generally within 1.8 m. Install protective case 5 in the foundation ditch mouth of shaft tower, this protective case is glass steel pipe, and its diameter should be with foundation ditch mouth size phase-match, and protective case 5 adopts bolt 4 articulated mode to be connected with top cap framework 1 for it prevents the crater cave mouth and collapse around to protect. Round holes are formed in the grid plates 6 above the top cover framework 1 connected with the protective sleeve 5, the peripheries of the openings of the grid plates are welded by flat steel to be covered, and burrs are polished. The circular grating plates 2 matched with the circular holes are embedded in the circular holes, and are divided into two parts at the diameter positions, edge covering and polishing are also carried out, so that the two semicircular steel grating plates are connected at the diameter positions through hinges and can smoothly cover the circular holes. The edges of the two semicircular grating plates are provided with opening handles 7, so that the opening is convenient. The top cover framework 1 is installed on the side wall 9 of the tower foundation pit through a ground anchor rod 8.
The load of the patent cover plate is considered according to the load of the routing inspection steel platform, and the construction bearing weight is not considered. The effective deep basal pit of this kind of patent apron protects the mouth, effectively guarantees that constructor and wild animal do not fall the foundation ditch, effectively prevents that harmful gas from gathering, effectively prevents the safety in production accident, reduces the inconvenient scheduling problem of transportation, makes the work progress more standard and standard, effectively guarantees safe civilized construction.
The middle parts of the integral cover plates are connected by hinges, the ventilation pipe can be placed down only by lifting one side cover plate in the forced replacement ventilation operation, and the operation is convenient, safe and reliable. Yellow and black paint is coated on the surface of the grid plate on the top surface of the cover plate, the cover plate is attractive and striking in appearance, the safety protection reliability in the construction process of the deep foundation pit of the transmission tower foundation is fully ensured, and the cover plate has a great popularization significance particularly in the construction on the paths of mountainous regions and unmanned areas.
