Abstract
The utility model relates to a portable inspection well protective device. The portable inspection well protective device comprises a top plate. An inner side frame is welded at the bottom of the top plate, wherein the size of the inner side frame is matched with that of a well cover which needs to be protected and the inner side frame is used for clamping and fixation. The portable inspection well protective device has the advantages of being simple in process, labor-saving, capable of preventing the well cover being damaged and guaranteeing that appearance of the well cover is clean and tidy, free of secondary pollution, capable of better meeting strength requirements, not prone to being damaged easily, and light in self weight of a finished product.
Description
Technical field
The utility model relates to a kind of manhole protective device, particularly a kind of portable manhole protective device.
Background technology
Tradition worker method constructing operation complexity, cost is bigger, and the finished product well lid is had destruction.
The utility model content
Technical problem to be solved in the utility model provides a kind of not fragile, and finished product is from the manhole protective device of heavy and light.

Description of drawings
Fig. 1 is the utility model square structure schematic diagram;
Fig. 2 is the utility model circular configuration schematic diagram;
In the accompanying drawing, the list of parts of each label representative is as follows:
1, top board, 2, rim, 3, lift the hole, 4, support bar.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As illustrated in fig. 1 and 2, this worker method adopts steel plate, and (steel plate thickness generally is advisable at 4mm) is according to the appearance and size cutting of well lid.(plate size has more 2-4mm) than well lid size and forms steel protection top board 1 usually.Below top board 1, press fixedly rim 2 of well lid internal orifice size welding steel.Material adopts both light, and the channel-section steel of rigidity is arranged again.In order to satisfy the rigidity requirement, can in rim, increase by two word support bars 4.In order to lift conveniently moving, in the appropriate location of protection top board, the circular bore of two diameter 20mm of processing is for lifting hole 3 at last.By " lifting handle " that the dimensioned of " lifting the hole " satisfies requirement of strength, (press inlet for stom water inside casing size) is when paver is passed by under the horizontal force action of generation.Rectangle frame is adjacent to rim, can not produce to move horizontally; Upper former is pressed the inlet for stom water housing and is made, and just covers the rainwater crib during placement, does not produce under the situation about moving horizontally in template, guarantees the not contaminated and crib pavement quality on every side of crib.
This device was promoted completely in West Road, Qinshui highway construction in 2011, and in advance 5 days durations, total well 366 covers of this engineering adopt this device to save 37332 yuan of costs than traditional bamboo offset plate, have saved 85% cost, have tangible economic benefit.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
