Abstract

The utility model discloses a pressure-proof environment-friendly well lid. According to the pressure-proof environment-friendly well lid, a lid body is filled with cement, a reinforcing steel bar and a switch are arranged inside the lid body, the inner surface of the lid body is semicircular, the surface of the lid body is flat and is formed by plastic or glass fiber reinforced plastic in a pressing mode, the middle portion of the lid body is a cavity, the cavity is filled with cement, the reinforcing steel bar arranged inside the lid body is semicircular, a groove and the switch are arranged inside the lid body, a guide groove is further formed in the groove, clamping bolts are connected with the switch through connecting lines, and a plastic pipe is arranged inside the cavity. According to the pressure-proof environment-friendly well lid, the problem that an ordinary well lid which is formed by iron in a casting mode and a cement well lid are large in strong pressure intensity is solved, weight of the pressure-proof environment-friendly well lid is almost the same as the weight of the ordinary well lid which is formed by iron in the casting mode and the weight of the cement well lid, cost of the well lid is low due to the fact that the plastic used is recovered waste plastic, high pressure can be borne, the service life is long, the well lid is not prone to breakage, the well lid can not be lost easily, and the well lid is an environment-friendly material.

Description

A kind of resistance to compression environmental protection well cover

Technical field

The utility model relates to a kind of resistance to compression environmental protection well cover.

Background technology

Well lid is on the city has stable political situation traffic route, use steel, iron well lid easy-to-rust and steal lose, too heavy, the easy defective such as embrittlement, cause vehicle or injury to personnel, be head it off, but the technician studies the cement well lid cracky, there is the operation glass fibre reinforced plastic manhole covers in market recently, though corrosion resistance, intensity are high, but weight, light cost are high, and inconvenience is promoted the use of, the utility model adopts the combined type multiple material mutually to replenish for solving this technical problem.

Summary of the invention

The defective and the technical problem that produce for solving the existing market well lid, the utility model glass fiber reinforced plastic, cement, plastics and reinforcing bar, and lock is set.

The technical scheme that the utility model technical solution problem adopts is that this resistance to compression environmental protection well cover is comprised of well lid and well head cover, well lid is made of cap surface, lid and lid inner face, filled by cement in the lid, in add reinforcing bar, if switch, the lid inner face is the semicircle arcuation, bonding connection between each parts; Cap surface is plane, and is more bigger than lid, forms the convex edge cover rim, is made of glass fiber reinforced plastic, and its thickness is 1.5-2cm; Top surface forms with plastics (or glass fiber reinforced plastic) compacting, and the centre is cavity, is filled by cement, with the cap surface bonding connection; Lid Nei Jianeijia reinforcing bar is the semicircle arcuation; Lid arranges groove and switch, and groove is also established guide groove, and snib is connected with line with switch, settles plastic pipe in cavity; The sheathed projection of well head, under edge on the well head and the well head along between.

The beneficial effects of the utility model are to use glass and cement, plastic or other material, increase reinforcing bar and employing semicircle mechanism, solving common cast iron casting well lid and cement well lid, to suppress intensity large, and weight is suitable, and used plastics are waste and old recycling, adopt in addition lock machine to close, play anti-theft function, keep Land leveling, vehicle can not move later, so this well lid cost is low, and pressurized is large, life-span is long, unsuitable damaged, lose, belong to environment-friendly materials.

Description of drawings:

Fig. 1 is the well lid drawing in side sectional elevation, 1 cap surface among the figure, 2 switches, 3 cover rims, 4 lids, 5 lines, 6 grooves, 7 snibs, 8 lid inner faces, 9 reinforcing bars

Fig. 2 is the enlarged drawing of facing of Fig. 1 groove 6, among the figure 6 with 7 with Fig. 1 in identical, 10 projections, 11 guide grooves

Fig. 3 is well head cover top view, and 10 is identical with Fig. 2 among the figure, edge on 12 well heads, edge under 13 well heads

The specific embodiment:

This resistance to compression environmental protection well cover, be comprised of well lid and well head cover, well lid is made of cap surface 1, lid 4 and lid inner face 8, is filled by cement in the lid, gain in weight, in add reinforcing bar 9, gain in strength, establish switch 2, rise and pin well lid, lid inner face 8 is the semicircle arcuation, and it is main also to play resistance to compression, bonding connection between each parts; Cap surface 1 is plane, and is more bigger than lid, forms convex edge cover rim 3, is made of glass fiber reinforced plastic, and its thickness is 1.5-2cm, uses this material both attractive in appearance, and durable again, compressive strength is large; The compacting of top surface 1 usefulness plastics (or glass fiber reinforced plastic) forms, and the centre is cavity, is filled by cement, with cap surface 1 bonding connection; Lid 1 Nei Jianeijia reinforcing bar 9 is the semicircle arcuation; Lid 4 arranges groove 6 and switch 2, and groove is also established guide groove, and snib 7 is connected with switch 2 usefulness lines 5, settles plastic pipe in cavity; The sheathed projection 10 of well head, on the well head along 12 and well head under along 13 between.

The method of operating of this well lid, well lid and well head cover are closed, identical with the cover rim 3 of well lid along 12 on the well head, under the well head along 13 with the well body under along coincideing, the projection 10 of well head cover enters groove 6 by the guide groove 11 on the well body 4, opening switch 2 is under the affecting of line 5, snib 7 blocks projection 10, and well lid is just installed, and the non-management people is not with unlocking key not open.
