Detailed Description
The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.
As shown in fig. 1 to 8, the through type electric inspection well structure suitable for quick assembly comprises a bottom plate 1, a vertical shaft 2, a manhole cover plate 3, a protruding block 4 arranged on the upper surface of the bottom plate 1, a groove 5 arranged on the lower surface of the vertical shaft 2 and used for clamping the protruding block 4, a steel bar sleeve unit 6 arranged on the upper surface of the bottom plate 1, an in-groove steel bar unit 7 arranged on the lower surface of the vertical shaft 2 and used for being in threaded connection with the steel bar sleeve unit 6, and a sealing layer unit 8 arranged between the upper surface of the bottom plate 1 and the lower surface of the vertical shaft 2 and used for filling the steel bar sleeve unit 6 and the in-groove steel bar unit 7 in grouting.
In this embodiment, the manhole is rectangular or circular, and the corresponding bottom plate 1, vertical shaft 2, and manhole cover 3 are also rectangular or circular, and the manhole cover 3 is further provided with a manhole cover mounting structure.
The protruding blocks 4 and the grooves 5 are arranged in pairs and aligned left and right, when the vertical shaft 2 is lowered, the protruding blocks and the grooves are just clamped, the reinforcing steel bar sleeve units 6 and the reinforcing steel bar units 7 in the grooves all comprise a root portion of a pre-buried threaded reinforcing steel bar, and the full threaded connection effect between the protruding blocks and the grooves is finally achieved.
Finally, the sealing layer unit 8 is formed by curing a sealing material, which may be an epoxy resin, an epoxy mortar, or a high-performance cement mortar. The thickness of the sealing layer unit 8 depends on the temporary fixing height of the vertical shaft 2, that is, when the sealing layer unit 8 is filled with grouting, the vertical shaft 2 can be suspended by a hoisting mechanism and/or supported by the screw structure of the steel bar sleeve unit 6 and the in-groove steel bar unit 7.
Still alternatively, the thickness of the protruding block 4 is greater than the depth of the groove 5, and at this time, the thickness of the sealing layer unit 8 between the bottom plate 1 and the vertical shaft 2 is greater, and the thickness between the protruding block 4 and the groove 5 is the thickness caused by the uneven contact surface, which is not optimal for the sealing effect of the sealing layer unit 8, but may omit the requirement of continuous suspension operation of the lifting mechanism.
The steel bar sleeve unit 6 comprises a lower threaded steel bar 601 with the lower end pre-embedded in the bottom plate 1 and the upper end exposed, and an inner threaded pipe 602 which is arranged on the lower threaded steel bar 601 and is used for being in threaded connection with the steel bar unit 7 in the groove.
In this embodiment, the reinforcing sleeve unit 6 needs to be located away from the protruding block 4, and similarly, the in-slot reinforcing unit 7 and the groove 5 are also laterally offset.
The steel bar sleeve unit 6 further comprises a radial column 603 which is arranged on the outer ring surface of the internal thread pipe 602, is positioned between the lower surface of the vertical shaft 2 and the upper surface of the bottom plate 1, and is used for rotationally lifting the internal thread pipe 602 and inserting the sealing layer unit 8.
In this embodiment, the radial column 603 has at least the following 2 roles;
the distance between the lower surface of the vertical shaft 2 and the upper surface of the bottom plate 1 is 1-5cm, and the space is inconvenient for the hand to extend into, so that the internal thread pipe 602 is difficult to rotate upwards, the radial column 603 is properly protruded outwards and can be used as a force application part for rotating the internal thread pipe 602, and the hand does not need to extend into the space greatly at the moment, so that the space is very convenient and safe;
secondly, the sealing layer unit 8 needs grouting to be filled in the steel bar sleeve unit 6 and the steel bar unit 7 in the groove, at this time, the structure of the steel bar sleeve unit 6 is more complex and three-dimensional due to the radial column 603, so that the connection strength between the steel bar sleeve unit 6 and the sealing layer unit 8 is higher, the screw connection strength of the steel bar sleeve unit 6 and the steel bar unit 7 in the groove is higher, and the screw connection stability is longer.
Of course, the length of the radial columns 603 should not be too great to protrude beyond the extent of the area of the lower surface of the vertical well bore 2.
The in-tank rebar unit 7 includes a vertical groove 701 provided on the lower surface of the vertical shaft 2 and used for inserting the lower screw rebar 601, and an upper screw rebar 702 provided on the inner top surface of the vertical groove 701 and used for screwing the inner screw pipe 602.
In this embodiment, when the vertical shaft 2 is lowered to a preset depth by using the lifting mechanism, the lower twisted steel 601 is vertically aligned with the upper twisted steel 702, at this time, the internally threaded pipe 602 is rotationally lifted, so that the steel bar sleeve unit 6 and the in-groove steel bar unit 7 can be connected into a whole, and when the sealing layer unit 8 is poured subsequently, the lifting mechanism can be maintained or withdrawn, or in the latter way, the weight of the vertical shaft 2 is temporarily pressed on the steel bar sleeve unit 6 and the in-groove steel bar unit 7, which is also possible.
The in-groove reinforcing steel bar unit 7 further comprises a lower slurry inlet 703 which is arranged between the outer side surface of the vertical shaft 2 and the vertical groove 701 and is used for rotationally lifting the internal thread pipe 602 and pouring the sealing layer unit 8.
In this embodiment, the sealing material of the sealing layer unit 8 has a path of travel of the lower slurry inlet 703, the vertical groove 701, and the lower surface of the vertical shaft 2. Finally, the sealing layer unit 8 can bond and seal the vertical shaft 2 and the bottom plate 1, and can fill and structurally strengthen the steel bar sleeve unit 6 and the steel bar unit 7 in the groove.
The in-tank reinforcement unit 7 further comprises an upper grout outlet 704 which is arranged between the outer side surface of the vertical shaft 2 and the vertical tank 701 and has a height higher than that of the lower grout inlet 703.
In this embodiment, the upper grout outlet 704 may ensure that the sealing material flows more smoothly, and may completely fill the vertical groove 701, so as to further promote grouting filling and structurally strengthen the actions of the reinforcing bar sleeve unit 6 and the reinforcing bar unit 7 in the groove.
The vertical cross-sectional shapes of the lower pulp inlet 703 and the upper pulp outlet 704 are circular, and the diameter of the lower pulp inlet 703 is larger than that of the upper pulp outlet 704.
In this embodiment, the lower inlet 703 may also need to be extended into an arm or into a wrench for rotating the internally threaded tube 602, so that the diameters of the lower inlet 7038-15cm and the upper outlet 7042-3cm are respectively.
The sealing layer unit 8 comprises a transverse sealing layer 801 arranged on the upper surface of the base plate 1 and the upper surface of the protruding block 4, a vertical sealing column 802 arranged on the upper surface of the transverse sealing layer 801 and positioned in the vertical groove 701, and a transverse sealing column 803 arranged on the vertical sealing column 802 and positioned in the lower slurry inlet 703 and the upper slurry outlet 704.
In this embodiment, the thickness of the transverse sealing layer 801 is not necessarily equal everywhere, so that sufficient adhesion and sealing between the lower surface of the vertical shaft 2 and the upper surface of the bottom plate 1, including the protruding block 4 and the groove 5, is ensured, and the radial column 603 is located in the transverse sealing layer 801.
The vertical sealing column 802 is mainly used for sealing the screwed position between the internally threaded pipe 602 and the upper threaded steel bar 702, so that the internally threaded pipe 602 is not unscrewed after being installed. Finally, the transverse sealing columns 803 are used for sealing the lower slurry inlet 703 and the upper slurry outlet 704, so that no other holes exist on the vertical shaft 2, and the structural strength of the vertical shaft can be further improved. Of course, the "hole" does not include any line openings, in other words, at least 4 line openings are provided in the vertical shaft 2, i.e. in front of each other, in front of each other.
Annular wood board grooves 9 for blocking the sealing layer units 8 are respectively arranged on the upper surface of the bottom plate 1 and positioned at the inner side and the outer side of the protruding block 4.
In this embodiment, if the annular wood board groove 9 and the annular riser installed in the groove are not provided, the cured and formed shape of the transverse sealing layer 801 is insufficient and neat during pouring of the sealing layer unit 8, and the bonding and sealing strength of the transverse sealing layer 801 are reduced.
Wherein the upper end of the annular riser cannot block the lower slurry inlet 703.

In addition, in S2, the suspended state is maintained at least until all the reinforcing bar sleeve units 6 and the reinforcing bar units 7 in the groove are fully screwed, and the size of the installation pit is required to be slightly larger than that of the inspection well, otherwise, the lower grout inlet 703 and the upper grout outlet 704 are required to be all opened on the inner side surface of the vertical shaft 2, and both methods can ensure that the sealing material of the sealing layer unit 8 is smoothly poured.
In S3, if the suspended state is maintained, the curing effect of the seal layer unit 8 is facilitated, and there is no risk of crushing the reinforcing bar sleeve unit 6 and the in-groove reinforcing bar unit 7, but this is costly and inefficient, so that the reinforcing bar sleeve unit 6 and the in-groove reinforcing bar unit 7 are provided with 8-15 pairs, and the suspended state, if released, is not greatly affected.

Thirdly, the sealing layer unit 8 also covers and fills the reinforcing steel bar sleeve unit 6 and the reinforcing steel bar unit 7 in the groove, so that the screw structure of the reinforcing steel bar sleeve unit and the reinforcing steel bar unit is higher in strength, and the waterproof sealing performance of the sealing layer unit 8 is enhanced.
Fourth, the screwing operation of the reinforcing sleeve unit 6 and the in-groove reinforcing unit 7 is simpler and more flexible, the radial column 603 is used for rotating the internally threaded pipe 602, and the lower grout inlet 703 can assist in rotating the internally threaded pipe 602.
Fifth, the radial columns 603 may further increase the connection strength between the reinforcing steel bar sleeve unit 6 and the sealing layer unit 8, so that the self-firmness of the reinforcing steel bar sleeve unit 6 on the base plate 1 is further improved.
Sixth, when the sealing layer unit 8 is poured, the inner and outer 2 annular wood board grooves 9 are inserted into the wood boards, so that the curing and forming effects of the sealing material at the sealing layer unit 8 can be ensured to be more stable.
