Problems solved by technology

Cement products are heavy, low in strength, especially poor in stain and corrosion resistance, high labor intensity during installation and inspection, and short service life; manhole covers made of cast iron can be recycled and easily lost, causing damage to pedestrians and vehicles. Security threats; due to the accelerated progress of municipal engineering science in our country, the integrated and systematic management of water, electricity, gas, and optical cables has been gradually implemented, and the area of ​​inspection manhole covers needs to be increased, with lighter weight, higher strength, anti-fouling, anti-corrosion, anti-shock and anti-theft. Comprehensive requirements make traditional cast iron manhole covers have no advantages

Embodiment 1

[0019] The wood core clad composite material anti-theft manhole cover described in embodiment 1 of the present invention, as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 As shown, it includes a well cover main body 2 and a frame 1. The well cover main body is composed of a wooden core 9 and a composite material layer 10 coated on the outer surface of the wooden core; built-in locking mechanism on the

[0020] Further, the wood core is a pressed board made of pine strips or solid wood strips cross-laminated at 90 degrees, and the thickness of the wood core is 45mm.

[0021] Further, the composite material layer is composed of unsaturated resin and glass fiber fabric, and the thickness of the composite material layer is 25mm.

[0022] Further, the built-in locking device includes a rotatable built-in lock 3 and an unlocker 4 that cooperates with the built-in lock. The lower part of the built-in lock is provided with an L-shaped clip 7; the frame is pr...

Abstract

The invention discloses an anti-theft well cover with a wooden core coated with a compound material. The anti-theft well cover comprises a well cover body and a frame, wherein the well cover body comprises a wooden core and a compound material layer covering the outer surface of the wooden core, wherein a built-in locking device capable of locking the well cover body onto the frame is arranged on the well cover body. A crossly-laminated solid wood plate is adopted as the wooden core, and the compound material with a certain thickness covers the outer surface of the wooden core, so that the anti-theft well cover is endowed with good corrosion resistance, aging resistance and slip resistance; and the anti-theft well cover comprises the frame with an insert hole and a built-in locking hole as well as a well cover with a built-in lock part and a special lock remover, so that compared with the conventional cement product and cast iron material, the anti-theft well cover has the advantages of high strength, light weight, corrosion resistance, long service life and the like, and the problem that the well cover is lost is also radically solved.

Description

technical field [0001] The invention relates to the field of inspection manhole covers for sidewalks and non-motor vehicle lanes in municipal engineering, in particular to a light-weight, anti-theft, anti-corrosion and impact-resistant wooden core-coated composite material anti-theft manhole cover. Background technique [0002] Existing municipal engineering sidewalks and inspection manhole covers for non-motor vehicle lanes are usually cement products and cast iron structures. Cement products are heavy, low in strength, especially poor in stain and corrosion resistance, high labor intensity during installation and inspection, and short service life; manhole covers made of cast iron can be recycled and easily lost, causing damage to pedestrians and vehicles. Security threats; due to the accelerated progress of municipal engineering science in our country, the integrated and systematic management of water, electricity, gas, and optical cables has been gradually implemented, a...
