Technical Field
[0001] The utility model relates to a temporary protective cover, in particular to a temporary protective cover used for an inspection well shaft. Background Art
[0002] The existing temporary protective cover of the inspection shaft is usually made of bamboo plywood and square wood at the construction site. There are even cases where bamboo plywood is directly covered as a protective cover. The construction of the temporary cover of bamboo plywood and square wood is as follows: 3 to 4 square woods are arranged in parallel, and bamboo plywood is laid on them and fixed with nails. This kind of cover is usually uneven, and the size is different from the size of the shaft, which is easy to cause displacement and expose the shaft mouth. At the same time, the bamboo plywood itself is prone to aging and damage under natural conditions, which is easy to cause safety hazards.
[0003] Therefore, how to improve the stability, convenience and reusability of the temporary protective cover of the inspection well shaft, thereby reducing labor costs, comprehensive costs after recycling and safety risks, and optimizing and improving the existing temporary protective cover is an urgent problem to be solved.

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0014] Figure 1 It is a schematic plan view of a temporary protective cover for an inspection well shaft according to the utility model; Figure 2 It is a schematic elevation view of a temporary protective cover for an inspection shaft of the utility model.
[0015] See also Figure 1 and Figure 2 The utility model provides a temporary protective cover for an inspection shaft, comprising an upper cover plate 1 and a bayonet frame, wherein anti-slip strips 2 are arranged in a criss-cross array, the size of the upper cover plate is larger than the size of the bayonet frame, and the buckle frame is formed by splicing four sections of steel rings 3 with L-shaped cross sections, wherein the bottom horizontal steel sheet reinforces the inward bending resistance of the vertical steel sheet; a buckle steel sheet 4 is arranged on the outer side of the steel ring 3, and a semicircular through hole is penetrated in the middle of the buckle steel sheet 4.
[0016] The utility model provides a temporary protective cover for the inspection shaft, wherein the upper cover plate 1 is a galvanized steel plate with a thickness of 1.5 mm and a length and width of 1500 mm (designed according to the conventional typical inspection shaft inner size of 1000 mm*1000 mm, and other sizes are adjusted by analogy). The anti-slip strips 2 of two adjacent rows are processed and arranged as follows: one row is arranged at equal intervals in the horizontal direction, and the other row is arranged at equal intervals in the vertical and horizontal directions in an alternating manner to strengthen the anti-slip friction surface, such as Figure 3 and Figure 4 shown.
[0017] The utility model provides a temporary protective cover for an inspection shaft, wherein the steel ring 3 is a galvanized steel ring, and the length of each section of the galvanized steel ring is 960mm. The thickness of the galvanized steel ring is 1.5mm, the length of the L-shaped cross section is 3mm, and the height of the L-shaped cross section is 6.5mm. The snap-on steel sheet 4 is a galvanized snap-on steel sheet, and the number of the galvanized snap-on steel sheets is 8, with 2 galvanized snap-on steel sheets arranged on each section of the steel ring 3. The thickness of the galvanized snap-on steel sheet is 1mm, the total section height is 65mm, the width is 50mm, the radius of the middle inner semicircle is 14mm (the upper and lower ends are 18.5m high), such as Figure 5 and Figure 6 shown.
[0018] The temporary protective cover for the inspection shaft provided by the utility model has no deviation or separation after installation. The specific applications are as follows:
[0019] When installing the temporary protective cover of the inspection well shaft, align the buckle frame of the protective cover with the inner wall of the inspection well shaft. If the size of the well wall is smaller than the design size, the protective cover can be slowly pushed through the buckle steel sheet 4 until the steel plate fits the upper surface of the well shaft; if the size of the well wall is larger than the design size, the buckle steel sheet 4 of the protective cover can be fine-tuned with tools such as pliers to make the buckle steel sheet 4 basically fit the inner wall of the well shaft (the buckle steel sheet is adjusted left and right to fit the inner wall of the well shaft left and right), and at the same time, the protective cover plate fits the upper and lower surface of the well shaft. Complete the installation of the temporary protective cover of the inspection well shaft.
[0020] The temporary protective cover for the inspection well provided by the utility model has the following technical effects:
[0021] 1. Compared with conventional square wood bamboo plywood covers, this device saves labor production time. According to the current construction speed, each protective cover saves 30 minutes on average. For the 19-04 Zhoupu Maintenance Institute new construction project, there are 103 inspection wells. Considering the situation that bamboo plywood is easily damaged and repeatedly made, it is equivalent to saving 10 labors. At the same time, because this device has a high reuse rate, its service life is generally more than 5 years. The construction period of these wells is calculated as 3 months. This device can be used 20 times within its service life; according to the scale of Zhoupu Maintenance Institute, it can save about 200 labors. At the same time, it also saves a lot of square wood and bamboo plywood.
[0022] 2. Compared with conventional square wood bamboo plywood covers, this device has improved accuracy, stability and convenience. Conventional square wood bamboo plywood has large size deviations, and most covers fail to stably cover the shaft, are prone to displacement and falling off, are prone to aging, are prone to damage, and are prone to high-fall accidents. This device is accurate in size and compatible with shafts with certain dimensional deviations within the shaft, without displacement, damage, or detachment, which greatly improves the accuracy and stability of the cover. Traditional bamboo plywood is easy to damage, and workers often resist the need to repeatedly make, repair, and replace covers, causing delays in the covering of the covers. This device is made of thinner galvanized steel plates, which not only meet the strength and durability requirements, but are also very light and easy to install, and are formed in one step, which greatly improves convenience and stability. This greatly reduces the incidence of high-fall accidents in shafts.
[0023] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
