Abstract

A modular concrete inspection well relates to an inspection well for various underground pipes, and comprises a prefabricated well bottom board, a bottom protecting board, a bottom cylinder with a piping hole, a cylindrical shell section, and a cone bench type wellhead. The utility model is characterized in that the bottom protecting board is fixed on a bottom board, the bottom protecting board is cased on the bottom cylinder which is to support and to be fixed on the well bottom board, the cylindrical shell section is fixedly connected on the bottom cylinder through a complementary type spigot-and-socket butt-joint port, and the wellhead is fixedly connected on the cylindrical shell section through the complementary type spigot-and-socket butt-joint port. The utility model is fast in speed of well construction, short in period, and easy in construction, and the quality of wells is easy to guarantee.

Description

The assembly type concrete inspection well

Technical field

The utility model relates to a kind of buried pipeline manhole.

Background technology

The manhole of existing buried pipeline all is to adopt traditional grooving, fluid concrete basis, loam brick layering to build pit shaft, shaft in wall by laying bricks or stones to wipe one's face, install the job practices of walling crib and well lid and build, and operation is many, troublesome poeration, long construction period.Because it is bigger that construction is subjected to artificially to reach the influence of natural conditions, thereby the quality of well is difficult for guaranteeing, uses and safeguards and brought totally unfavorable influence for later.Moreover traditional method shaft building construction ground area is big.

Summary of the invention

The purpose of this utility model provides and a kind ofly is suitable for that all kinds of buried pipelines use, and the shaft building constructing operation is easy, and the cycle is short, the assembly type concrete inspection well that the quality of well is easy to guarantee.

The assembly type concrete inspection well by prefabricated shaft bottom plate, river bottom protection plate, have end tube, shell ring and the frustum type well head of taking over the hole and constitute, the river bottom protection plate is fastened on the plate of shaft bottom, end jacket casing dress river bottom protection plate and supporting are fixed on the plate of shaft bottom, and end tube and river bottom protection inter-board interface tamp floating with cement mortar and with sealing joint.Shell ring is fixed on the end tube by complementary socket joint docking port supporting, and interface tamps floating sealing with cement mortar.Well head is fixed on the shell ring by complementary socket joint docking port supporting, and interface tamps floating sealing with cement mortar.

In order to adapt to different instructions for uses, further improving of assembly type concrete inspection well be, on the river bottom protection plate plate face wall by river bottom protection plate symmetrical centre being arranged is the groove of cambered surface, and groove two groove ends dock with end socket joint pore.

For the ease of being connected of manhole and underground pipe, socket joint pore place, the end barrel of assembly type concrete inspection well has the tubulature mouth, and plate is equipped with at tubulature mouth place.Plate plate face constitutes the part of end tube tube wall surface, and its upper surface constitutes the part of tube upper surface, the end, and its lower surface constitutes a part of taking over the hole wall surface of the hole.

The assembly type concrete inspection well is made of prefabricated concrete well spare, and on-the-spot the assembly assembling cement mortar sealed interface, constructing operation is easy, and speed of shaft sinking is fast, and the cycle is short, and the quality of well is easy to guarantee.Shaft building construction area area is little, is beneficial to civilized construction.

Description of drawings

Fig. 1 is an assembly type concrete inspection well appearance assumption diagram.

Fig. 2 is the sectional view of manhole shown in Figure 1.

The specific embodiment

Shown in the accompanying drawing a kind of embodiment of the present utility model, below in conjunction with description of drawings embodiment of the present utility model.

As Fig. 1, shown in Figure 2, assembly type concrete inspection well cross section is circular, by prefabricated reinforced concrete well base plate (4), steel fibrous concrete river bottom protection plate (8), tube at the bottom of the steel fibrous concrete (3), shell ring (2) and frustum type well head (1) constitute, it is the groove that passes through river bottom protection plate symmetrical centre (9) of cambered surface that wall is arranged on the river bottom protection plate plate face, adapter hole (7) is arranged on the end tube, (10) and be loaded on the plate (5) at tubulature mouth place, (6), the river bottom protection plate connects with cement mortar and is adhesively fixed on the plate of shaft bottom, end jacket casing is adorned the river bottom protection plate and is adhesively fixed on the plate of shaft bottom with cement mortar, river bottom protection plate groove two notches are taken over the hole with two of end tube and are docked, end tube and river bottom protection inter-board interface tamp floating sealing with the cement pump slurry, the plate plate face of end tube constitutes the part of end tube tube wall surface, the plate upper surface constitutes the part of tube upper surface, the end, its lower surface constitutes a part of taking over the hole wall surface of the hole, shell ring is fastened on the end tube by complementary socket joint docking port, interface tamps floating sealing with cement mortar, the frustum type well head is fixed on the shell ring by complementary socket joint docking port supporting, and interface tamps floating sealing with cement mortar.
