Abstract
The utility model disclose a special-shaped well cover combination of an inspection well, comprising a special-shaped well cover (2), a special-shaped well seat (1) and a special-shaped well curb (4), wherein the well cover (2), the well seat (1) and the well curb (4) built-in the well seat (1) are all uniform shape of triangle, or diamond, or pentagon, or hexagon, or heptagon, or octagon, or fan, or pentagram, or stared polygon. The well cover (2) is provided with a down-concave groove at the center. The well cover (2) is connected with the well seat (1) through a hinge, or directly being paved on the well curb (4) of the well seat (1). The special-shaped well cover combination of an inspection well of the utility model is capable of reducing the subsidence degree or inclination degree of the inspecting well under pressure effect, and utilizing a hinge to connect one side of the well cover to the well seat, making the well cover freely open and close. The special-shaped well cover combination of an inspection well changes the force condition of common well cover during being pressed, making the well cover uneasy to turn over, which can reduce traffic accidents.
Description
Technical field
The utility model relates to manhole shaft, in particular to the well lid of manhole shaft, also relates to relative well seat and walling crib.
Background technology
The well lid of manholes such as traditional drainage inspection well, rainwater inspection well, sewage manhole all is circular, square or rectangle basically.Circular manhole uses the most extensive.But traditional manhole often exist well lid easily pushed by wheel and rout up, shortcoming such as casting iron well lid is often stolen.These problem already cause people's attention.The Chinese patent application part that relates to the manhole well lid reaches thousands of.Most technical schemes are to improve from well lid structure and material, but still adopt traditional circle or rectangle.As CN00112189.8 " plumbing manhole cover, seat and production technology thereof ", CN00132052.1 " manhole cover made of composite material and well seat " etc.But these schemes thoroughly do not solve the shortcoming that existing manhole well lid exists yet.For this reason, people constantly study new well lid, make its more convenient durable, road travel and pedestrian safer.
Summary of the invention
The purpose of this utility model is to provide the combination of manhole abnormity well lid, to overcome the shortcoming of existing manhole well lid.
For reaching this purpose, the manhole abnormity well lid combination of designer's design comprises special-shaped well lid, special-shaped well seat and special-shaped walling crib, pre-buried special-shaped walling crib is unified shape on abnormity well lid, special-shaped well seat and the special-shaped well seat, being connected of well lid and well seat can adopt hinge to connect, and also can adopt traditional mode bedding on the walling crib of well seat.
Abnormity well lid, special-shaped well seat with and on special-shaped walling crib do not adopt traditional circle, square, rectangle, they or be triangle, or be rhombus, or be pentagon, or be hexagon, or be heptagon, or be octagon, or be fan-shaped, or be pentalpha, or be polygonal star, even can be arbitrary shape, but easy for installation in order to make, adopt equilateral triangle or regular polygon or rhombus usually.
Adopt special-shaped well lid, and make the well lid plane consistent with ground level, special-shaped well lid center covers pit shaft, and the angle on each limit supports on the ground, can reduce the pressure to manhole such as vehicle, pedestrian, thereby prevent the sinking of manhole; There is a recessed groove at the well lid center, supplies the fixedly usefulness of well lid.
The material of abnormity well lid can adopt materials such as cast iron, glass fiber reinforced plastic, steel concrete, polypropylene fiber concrete, polymer matrix composites to make.
Manhole abnormity well lid provided by the utility model combination can alleviate the degree that manhole sinks under pressure or tilts; And can adopt hinge that one side of well lid is connected on the well seat, and opening and closing freely, well lid is difficult for being pushed and routing up by wheel; Can reduce traffic accident.
