Technical problem to be solved by this invention is to provide a kind of pre-fabricated electric cables well and cable duct cast-in-place structure syndeton, and the construction method of this syndeton, cause the pre-fabricated electric cables well borehole wall and concrete pack to ftracture to solve because differential settlement, cast-in-place concrete structure exist the factors such as retractility, the technical problem such as to leak.
For realizing above-mentioned technique effect, the invention discloses a kind of pre-fabricated electric cables well and cable duct cast-in-place structure syndeton, comprise plural reinforcing bar connector, plural comb arrangement of reinforcement, plural cable sleeve and plural cable duct bank, described reinforcing bar connector one end connects the L shape reinforcing bar be embedded among the borehole wall, the other end connects described comb arrangement of reinforcement, multiple cable sleeve is set in the borehole wall and is socketed described cable duct bank one by one, outside the borehole wall, have a plate groove to mate with comb concrete pack.
Described syndeton is further improved and is, described reinforcing bar connector adopts with described L shape reinforcing bar and described comb arrangement of reinforcement and is threaded.
The invention also discloses the construction method of a kind of pre-fabricated electric cables well and cable duct cast-in-place structure syndeton, comprise the following steps:
Step 1, in pre-fabricated electric cables well reinforcing bar binding process, arranges a L shape reinforcing bar and adopts colligation or welding manner to be fixed on pre-fabricated electric cables well borehole wall arrangement of reinforcement, and be threaded with described reinforcing bar connector by described L shape reinforcing bar;
Step 2, at reserving hole place installing cables sleeve pipe, is fixedly connected with borehole wall arrangement of reinforcement;
Step 3, before pre-fabricated electric cables well is built, reserves plate groove at the borehole wall, the dark 30mm of plate groove;
Step 4, pre-fabricated electric cables well reaches intensity, after installation in position, carries out the construction of its periphery concrete pack, adopts die head threading machine to process comb arrangement of reinforcement, outside comb arrangement of reinforcement and embedded bar connector are connected firmly;
Step 5, installing cables comb after reinforcement construction completes, guarantees that same cable sleeve interface is tight;
Step 6, shuttering, carries out the connection that the pre-fabricated electric cables well borehole wall and cast-in-situ concrete are encapsulated, strictly need control, guarantee that the Concrete Filled in plate groove is closely knit in the concrete construction of seaming position.
The invention has the advantages that:
1) globality of pre-fabricated electric cables well and concrete pack is ensured by the bar connecting of the borehole wall and encapsulating;
2) solve waterproof requirement by cable sleeve, solve issuable uneven subsidence by the aboveground reserved plate groove of pre-fabricated electric cables;
