Description

Steel casing brick drainage inspection shaft

Technical Field

The utility model relates to a drainage structures, in particular to steel casing pipe brick drainage inspection shaft.

Background

In a water supply and drainage pipeline system, a drainage inspection well is suitable for rain and sewage drainage pipelines, has important functions of connecting pipelines, inspecting and maintaining pipelines and the like, is a necessary accessory structure convenient for regular inspection and dredging of pipelines and preventing pipeline blockage, and generally comprises a cover plate, a well cover, a shaft and a base, various pipelines such as rainwater, sewage, water supply and the like need to be buried at the lower part of an urban road, and a corresponding drainage inspection well is arranged on a road surface layer. At present, drainage inspection wells for drainage pipelines mainly have the following three types: (1) laying a drainage inspection well by bricks; (2) a concrete module type drainage inspection well; (3) prefabricated assembled reinforced concrete drainage inspection shaft. The construction process of the drainage inspection well (2) and the drainage inspection well (3) is complex, and the process of the drainage inspection well (1) is simpler than the processes of the drainage inspection well (2) and the drainage inspection well (3), so that most of the drainage inspection wells used in the construction engineering are of the form (1). However, the drainage inspection well constructed by using the bricks and the cement mortar generally adopts a construction mode of excavating and taking earthwork and then constructing, when the drainage inspection well with larger burial depth needs to be constructed or a drainage inspection well is newly added on a drainage pipeline which is already constructed, the range of excavated earthwork needs to be gradually enlarged from bottom to top during construction, corresponding protection and support measures need to be taken to avoid collapse of the earthwork during construction, and the earthwork needs to be refilled to the outer side of the drainage inspection well after construction, so that the construction difficulty is high, the risk coefficient is high, and the construction period is long.

Disclosure of Invention

The utility model aims to solve the technical problem that a steel casing pipe brick drainage inspection shaft is provided, this kind of drainage inspection shaft can accomplish great buried depth's drainage inspection shaft construction under the condition that need not large tracts of land earthwork excavation and do not have other earthwork to it is more convenient to newly add the drainage inspection shaft construction on the drainage pipe to accomplishing the construction.

In order to solve the technical problems, the technical scheme is as follows:

the utility model provides a steel casing pipe brick drainage inspection shaft, includes apron, pit shaft and bed course, and the apron sets up at the upper end opening part of pit shaft, and the bed course setting is opened at the lower extreme opening part of pit shaft on the apron has the inspection socket, installs inspection socket closing cap on the inspection socket, its characterized in that: the shaft comprises a steel sleeve shaft outer wall and a brick masonry shaft inner wall, the inner side face of the steel sleeve shaft outer wall is tightly combined with the outer side face of the brick masonry shaft inner wall, and the lower end of the steel sleeve shaft outer wall is provided with at least two notches for the drainage pipes to penetrate through.

When the steel sleeve brick drainage inspection well is constructed, firstly, the outer wall of a steel sleeve shaft is directly sunk at the position where the drainage inspection well needs to be arranged, so that a drainage pipe passes through the outer wall of the steel sleeve shaft through a gap; excavating the earthwork at the inner side of the outer wall of the steel sleeve shaft to expose the drain pipe; then breaking the drain pipe, arranging a bottom cushion layer, and sealing the lower end opening of the outer wall of the steel sleeve shaft and a gap between the notch and the drain pipe; and finally, building the inner wall of the brick masonry shaft on the inner side of the outer wall of the steel sleeve shaft, enabling the outer side surface of the inner wall of the brick masonry shaft to be tightly combined with the inner side surface of the outer wall of the steel sleeve shaft, and sequentially arranging the cover plate and the well cover, thereby completing the integral construction of the drainage inspection well. When the drainage inspection well is constructed, the outer wall of the steel sleeve shaft is firstly sunk into the drainage pipe, the drainage pipe penetrates through the outer wall of the steel sleeve shaft through the gap, and then earthwork in the outer wall of the steel sleeve shaft is excavated, so that the range to be excavated is limited through the outer wall of the steel sleeve shaft, meanwhile, the outer wall of the steel sleeve shaft can play a role in supporting and protecting when earthwork is excavated and the inner wall of the brick masonry shaft is built, the drainage inspection well with larger burial depth is arranged or a drainage inspection well is newly added on the completed drainage inspection well with larger burial depth, large-area excavation is not needed, the drainage inspection well is more convenient to add, and earthwork does not need to be backfilled to the outer side of the drainage inspection well after building, so that the construction difficulty and the construction risk coefficient are reduced; the pit shaft adopts the mode that steel casing pit shaft outer wall and brick brickwork pit shaft inner wall combined together, makes the section of thick bamboo wall of pit shaft have higher intensity to steel casing pit shaft outer wall can increase the leakproofness of pit shaft, effectively prevents that the problem of poor, the easy infiltration of well casing wall rigidity in traditional brick brickwork inspection shaft from appearing in the drainage inspection shaft in this application.

In a preferred scheme, the bottom cushion layer is a concrete cushion layer.

The number of the gaps through which the water supply and drainage pipes penetrate can be two or more, the trend of the drainage pipes generally comprises a straight line trend, a T-shaped trend or a cross trend when the drainage inspection well is arranged, and the positions and the number of the gaps can be set according to the trend of the drainage pipes.

The lower extreme of above-mentioned brickwork pit shaft inner wall is sealed with the junction of bed course, and brickwork pit shaft inner wall is sealed with the junction of drain pipe surface.

The beneficial effects of the utility model reside in that: the drainage inspection well can complete the construction of the drainage inspection well with larger burial depth under the conditions of not needing large-area earthwork excavation and not needing other earthwork supporting measures, and is more convenient to construct by newly adding the drainage inspection well on the drainage pipeline which completes the construction.
