Background
Municipal works underground pipe networks are numerous, a drainage pipe network is the life line of the municipal works underground pipe networks, and a drainage inspection well is a window of the drainage pipe network. The pipeline connecting device has the advantages that the pipeline connecting device is used for connecting a pipe network with the ground, and plays a role in overhauling pipelines, removing sludge and connecting pipelines with different heights in different directions. In actual engineering, the types of inspection wells are many, such as a solid clay brick inspection well, a plastic inspection well, a cast-in-place reinforced concrete inspection well and the like. The first prior art is as follows: traditional municipal pipeline inspection shaft construction adopts solid clay brick laying, cement plastering mode mostly. The above-mentioned prior art has at least the following disadvantages: the solid clay brick inspection well has low strength, high water permeability and non-compact mortar among gaps, and after the solid clay brick inspection well is used for a period of time, the surface of the solid clay brick inspection well falls off and the inside of the solid clay brick is loose, so that the whole well body is easy to sink, the surrounding pavement is settled, and even underground water resources can be polluted. And because the raw material of the clay brick is sandy clay, a large amount of cultivated land resources are occupied and wasted during sintering. The second prior art is: at present, enterprises which are specially used for plastic inspection wells appear in domestic markets. The common plastic inspection wells include Ruipu plastic inspection well, Hema plastic inspection well, and Suitai plastic inspection well. The second prior art has at least the following disadvantages: plastic manhole inherently has many advantages of its own, but also has its inevitable drawbacks.

In addition, the foundation of the plastic inspection well is troublesome to process, and the problem of inclination of a shaft is easy to occur in the backfilling process, so that repeated construction is brought, and the uncontrollable cost is increased. The prior art is three: concrete block manhole is generally considered as an ideal substitute for clay bricks, and is the manhole material which is used more at present. The third prior art has at least the following disadvantages: although the concrete blocks are used for replacing clay bricks, the construction still needs on-site wet operation, the construction period is long, the condition of airing the groove for a long time on site cannot be completely got rid of, and the concrete blocks are not suitable for quick construction of pipelines. The concrete block type inspection well is suitable for small building inner diameter (about 1 m), poor in anti-seismic and anti-seepage effects, and has great difference due to different material sources, appearance sizes and production processes. The prior art is four: the cast-in-place reinforced concrete inspection well has good stability, high strength and ideal tightness. The prior art has at least the following disadvantages: the cast-in-place reinforced concrete inspection well has the advantages of long construction period, high difficulty, complex process, large amount of pouring templates required on site, high risk of deep well operation and no accordance with the requirement of short construction period of the actual municipal inspection well.
The current prefabricated inspection shaft straightness inconvenient control that hangs down when the installation, especially the prefabricated inspection shaft of multistage stack, after one section installation slope of bottommost, under the accumulative error, can lead to upper segment part to interfere seriously, the inspection shaft is easy to split, and the well lid at top easily produces the slope simultaneously to cause the ground unevenness.

When the lower shaft 1 is prefabricated, the stainless steel rings 8 are fixed at proper positions, the stainless steel rings 8 on the two sides need to ensure good coaxiality and the same height, and then the stainless steel rings 8 are solidified together when the lower shaft 1 is poured. The stainless steel ring 8 can better bear the local acting force applied by the rotating shaft 9, and the lower shaft 1 is prevented from cracking. The stainless steel ring 8 is installed at the upper end of the lower shaft 1 so that the lower end has a large weight when the rotation shaft 9 is inserted, thereby generating a large component force to drive the rotation of the lower shaft 1 when it is inclined. So that the lower wellbore 1 can be in a more vertical state.
Preferably, the center of the installation through hole 14 is 15cm-30cm away from the upper end surface of the lower shaft 1, and the lower position is too low, so that the lower shaft 1 cannot generate enough component force to drive the rotation when inclined, and the upper position is too high, so that the lower shaft 1 is easy to crack at the position. The diameter of the installation through hole 14 is 2-6cm, and the wall thickness of the stainless steel ring 8 is 3-7 mm. Its diameter needs to guarantee can not buckle when pivot 9 will descend pit shaft 1 to hoist, and pivot 9 is preferred to adopt stainless steel to make lower pit shaft 1 can the free rotation.

The splicing is convenient, the inspection well is arranged into a plurality of sections, and the installation and the manufacture are both convenient. Preferably, the well body adjusting device further comprises a well body adjusting cylinder 4 and a well lid adjusting cylinder 6, wherein the well body adjusting cylinder 4 is clamped between the lower well shaft 1 and the connecting end cover 5, one end of the well body adjusting cylinder 4 is provided with a ridge groove matched with the lower well shaft 1, and the other end of the well body adjusting cylinder is provided with a ridge 13 matched with the connecting end cover 5; the well lid is adjusted a 6 joints in top apron 7 with connect between the end cover 5. The height of the inspection well can be conveniently adjusted by adjusting the number of the well body adjusting cylinders 4 and the well cover adjusting cylinders 6, and the inspection well is suitable for inspection wells with different requirements.
Preferably, the edge of the grouting through hole 12 is provided with an annular boss 11, and the annular boss 11 is higher than the inner bottom surface of the lower shaft 1. The annular projection 11 is arranged so that concrete does not overflow into the lower shaft 1 when grouting down the lower shaft 1 through the grouting through hole 12.
In order to stably control the inspection well not to incline after the installation is finished, a fixing pile 2 is arranged in the grouting through hole 12, the tip end of the fixing pile 2 penetrates through the grouting through hole 12 and is inserted into the bottom of the pit, a limiting table 21 is arranged at the other end of the fixing pile 2, and when the fixing pile is installed in place, the limiting table 21 abuts against the annular boss 11. The diameter of the fixing pile 2 is the same as the diameter of the grouting through hole 12, and the fixing pile 2 is inserted after grouting is completed, so that the cylindrical surface of the fixing pile 2 is limited by the cylindrical surface of the grouting through hole 12, and the lower shaft 1 is controlled not to incline easily. When the bottom surface of the pit partially collapses, the lower shaft 1 can only move downwards in the vertical direction integrally under the guiding action of the fixing piles 2, and the local inclination cannot be generated, so that the detection well is integrally stable after being installed. Preferably, a sealing ring 3 is arranged between the limiting table 21 and the annular boss 11. It is possible to avoid concrete from entering the lower shaft 1 when installing the spud pile 2.
