Abstract

The invention relates to the field of construction, in particular, to the structures of observation wells of underground utilities. The purpose of this invention is to facilitate adjustment of the height of the tip and increase operational reliability by eliminating the shift of the tip. The inspection well has a bottom 1, walls 2, an overlap 3, a cover 4. The height of the well head is made up of a composite of the top 5 and bottom 6 of the annular sections. The overlap 3 is provided with an annular nozzle 7 located concentrically to the intermediate ring 8. Between them, an annular gap is formed filled with bulk material 9. The lower section 6 of the tip is inserted into the gap between the nozzle 7 and intermediate ring 8 and supported on the bulk material 9. The lid 4 of the well is supported on upper annular section 5 tip. 1 il.

seals) and re-insert elements 6.5 and 4.

If it is necessary to lower the level of the lid (shorten the well), remove elements 4.5 and 6 sequentially, and also remove loose material 9, insert ring 8, pour loose material back to the required one. The viewing mark is shown on the drawing (taking into account the sealing factor ) and insert elements 6.5 and 4 back.

underground communications utility, section The observation pit of the underground utilities has the bottom 1, the walls 2, the breakthrough 3, the cover 4. The height of the well head is made up of a composite of the top-15 and 5 and the bottom 6 of the annular sections. The overlap 3 is provided with an annular nozzle 7 located concentrically to the intermediate ring 8. Between them, an annular gap is formed, filled with 20

NB1Y bulk material 9. The bottom section 6 tip is wound up in the gap between the pipe 7 and the intermediate ring 8 and is supported on the bulk material 9. The lid 4 of the well is supported on the top 5 ring-25

Aiming the tip section. ;

Adjusting the height of the location of the well can be done as follows.

If it is necessary to increase the level of the grout 4 (extension of the well), remove the elements 5 and 6, successively pour loose material to the desired level (taking into account the coefficient, compaction) and reinsert the elements 6.5 and 4.

If necessary, lower the level of the lid (shorten the well), remove elements 4.5 and 6 in series, and also remove loose material 9, insert ring 8, pour loose material back to the required amount and insert elements 6.5 and 4 back.
