Fixed and reliable wellhead device for municipal engineering

Abstract

The invention discloses a fixed and reliable wellhead device for municipal engineering and relates to the technical field of municipal engineering. The fixed and reliable wellhead device for municipalengineering comprises an outer well lid, a drainage mechanism and a damping mechanism. Road surfaces are arranged on the outer side below the outer well lid, an inner well lid is arranged in the middle inside the outer well lid, a rotating shaft is arranged above the inner well lid, a movable shaft is arranged below the inner well lid, a sliding mechanism is arranged at the outer end of the innerwell lid, the drainage mechanism is arranged in the outer well lid, edge bosses are fixedly arranged on the outer side of the outer well lid, reinforcing rods are arranged above the edge bosses, andmounting plates are welded on four sides of each edge boss. The fixed and reliable wellhead device for municipal engineering in the invention has the beneficial effects that the edge bosses are arranged, thereby facilitating mounting of the inner well lid, the mounting plates are fixedly arranged inside the edge bosses at equal intervals, and the inside of each edge boss on the mounting plate partis solid casting, so that positioning bolts penetrate through thread grooves to jointly arrange the edge bosses and the outer well lid at the wellhead position.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a fixed and reliable municipal engineering wellhead device. Background technique [0002] Municipal engineering generally belongs to the country's infrastructure construction, which refers to the infrastructure construction of various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation and lighting in urban construction, and is an indispensable material for urban survival and development. The foundation is the basic condition for improving people's living standards and opening up to the outside world. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering. [0003] The drainage at the wellhead of the existing municipal engineering is small, and the size of the drainage cannot be adjusted according to the rainfall, and there is no cushioning fun...
