Description
Technical Field
The invention belongs to the technical field of communication, and particularly relates to a method for installing a cable prefabricated well.
Background
In recent years, with the continuous development of urban construction, pipeline construction becomes more and more important, and communication pipeline construction is an important part of municipal infrastructure. In the construction of communication pipes, it is necessary to construct communication wells at intervals on a road surface along a laying path in order to lay cables. The existing communication well generally adopts a field building process. The construction process has the following defects: firstly, the construction method occupies more workers and has long construction time; secondly, the brick structure has poor strength and low bearing capacity and is easy to damage; thirdly, the site masonry construction is easily affected by the weather environment, and the failure of the construction in rainy and snowy weather may cause the delay of the work period.
Disclosure of Invention
The invention provides a method for installing a cable prefabricated well, aiming at overcoming the defects of the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme: a method of installing a prefabricated well for a cable, the method comprising the steps of: a. and (3) treating the foundation of the installation position of the cable precast well, excavating a foundation trench:
b. constructing cushion concrete in the foundation trench:
c. the cable prefabricated well is prefabricated in four sections: lower well room, go up well room and well lid:
d. a plurality of reserved pipeline mounting holes are formed in the wall of the lower well chamber as required:
e. hoisting a lower well chamber to the cushion concrete, and then installing a corrugated pipe on the reserved pipeline installation hole:
f. hoisting the middle well chamber to the lower well chamber, connecting the middle well chamber and the lower well chamber through a first connecting mechanism, and hoisting the upper well chamber to the middle well chamber:
g. installing a well cover on the upper well chamber; before installation, all parts are processed, and during installation, all parts are only required to be respectively hoisted, so that the construction period is greatly shortened.
Preferably, the first connecting mechanism comprises an inserting plate and a screw which are arranged on the bottom of the middle well chamber and a slot which is arranged on the lower well chamber, and the inserting plate and the lower well chamber are both provided with threaded holes which are matched with the screw; when the well chamber is hoisted, the inserting plate is aligned to the inserting groove, then the inserting plate is inserted into the inserting groove, and then the bolt falls onto the inserting plate, so that the connection of the well chamber and the well chamber can be completed.
Preferably, elastic bulges are arranged on two sides of the inserting plate, and clamping grooves matched with the elastic bulges are arranged on the side walls of the inserting grooves; through the cooperation of elastic bulge and draw-in groove, can play good sealed effect.
Preferably, the upper part of the side wall of the slot is provided with an inclined surface; the inclined surface can play a guiding role for the insertion plate, so that the insertion plate is aligned with the slot conveniently.
In summary, all parts are processed before installation, and only need during installation hoist and mount respectively can, construction cycle has been reduced greatly.

Detailed Description
As shown in fig. 1 to 3, a method for installing a cable prefabricated well is characterized in that: the method comprises the following steps: a. treating the foundation of the installation position of the cable precast well, and excavating foundation trenches:
b. constructing cushion concrete in the foundation trench:
c. the cable prefabricated well is prefabricated in four sections: well chamber 1, well chamber 2, well chamber 3 and well lid 4 go up:
d. a plurality of reserved pipeline mounting holes 11 are formed in the wall of the lower well chamber 1 as required:
e. hoisting the lower well chamber to the cushion concrete, and then installing the corrugated pipe 12 on the reserved pipeline installation hole:
f. hoisting a middle well chamber onto a lower well chamber, connecting the middle well chamber and the lower well chamber through a first connecting mechanism, hoisting an upper well chamber onto the middle well chamber, wherein the first connecting mechanism comprises a plug board 41 and a screw 42 which are arranged on the bottom of the middle well chamber, and a slot 43 which is arranged on the lower well chamber, and the plug board and the lower well chamber are both provided with threaded holes matched with the screw; the slot 43 is arranged at the top of the well-descending chamber, and the upper part of the side wall of the slot is provided with an inclined surface 431; the inclined surface can guide the plugboard, so that the plugboard and the slot are aligned conveniently, when the well chamber is hoisted, the plugboard is aligned with the slot, then the plugboard is inserted into the slot, and then the bolt falls onto the plugboard, so that the connection of the well descending chamber and the well chamber can be completed; elastic bulges 43 are arranged on two sides of the inserting plate 41, and clamping grooves 44 matched with the elastic bulges are arranged on the side walls of the inserting grooves; through the cooperation of elastic bulge and draw-in groove, can play good sealed effect:
g. and installing the well cover on the upper well chamber.
