Description
Technical field
The present invention relates to underground utilities active well technology, be specifically related to a kind of precast splice type cable active well and job practices thereof.
Background technology
Existing underground utilities active well has several like this forms: active well and splicing prefabricated components formula active well that active well, cast-in-situ concrete active well, concrete block formula active well, splicing prefabricated components and the reinforced concrete cast-in-situ mode that adopts loam brick to be built into combines.The active well of wherein preceding four kinds of forms or have that intensity is low, easy to leak, non-resistant shortcoming, or the deficiency of long, workmanship poor reliability of construction period is arranged.With splicing prefabricated components mode construction work well do not need to carry out at the scene that a large amount of cast-in-situ concrete operations, speed of application are fast, easily backfill, antidetonation and barrier performance be good, is one of constructure scheme of constantly exploring of cable work technology and constructor.
But, at home, still do not have the precast splice type active well so far and occur.Abroad, the precast splice type active well is more common in Japan and Europe.Existing precast splice type active well is taked round drawer formula structure, and promptly the well type is got circle, is folded to fall to forming by the prefabricated ring of multilayer.This round shaft structure, carry out prefabricated units production though be convenient to utilize the mould and the technology of producing tubing, and the lateral pressure and the vertical pressure that acts on the well body of the soil body can be used or also can bear without reinforcing bar to prefabricated units less, but the shape choice of this active well is too little, be difficult to satisfy various occasions and use, especially be difficult to the needs of the various active wells in the appropriate cable construction.
Summary of the invention:
The purpose of this invention is to provide cable work well and job practices thereof by the assembled approximate rectangular build of some prefabricated component blocks, square build or dome gallery type.
Precast splice type cable active well provided by the invention comprises prefabricated component blocks, seal and connector, it is characterized in that: the cable work well that forms with splicing prefabricated components can be approximate rectangular build, square build or dome gallery type, described prefabricated component blocks shape is as approximate rectangular build, the block of the cable work well well body of square build or dome gallery type, its dividing method is for being divided into the well body two parts up and down earlier, longitudinally be that the cable direction of travel is divided into some building blocks more then, described prefabricated component blocks comprises termination upper member piece, termination lower member piece, changeover portion upper member piece, changeover portion lower member piece, well head section upper member piece, well head section lower member piece, ponding well building block is in each mutual pairing, height after the stack of lower member piece is the height of well body; The seam crossing that all prefabricated component blocks are spliced mutually all is lined with seal; Connect with connector between the prefabricated component blocks.
In order to improve the splicing intensity of active well, the vertical height of adjacent building block is different before and after on the horizontal direction, promptly makes the horizontal direction seam of adjacent building block up and down not be on the same horizon.
Job practices provided by the invention is carried out as follows:
I. cable work well bracing of foundation pit construction;
Ii. excavation of foundation pit;
Iii. concrete cushion is built;
Iv. at the impervious processing coating of the native face brushing of meeting of prefabricated component blocks concrete surface, paste the hydro-expansive rubber waterstop;
V. by getting on, get off, order assembly unit prefabricated component blocks is from front to back put seal at the seam crossing pad of contiguous prefabricated building block again, connects each prefabricated component blocks with connector;
Vi. cut off the prefabricated component blocks drop hanger, mend the impervious processing coating of brush concrete surface at former drop hanger position;
Vii. cable duct bank interface construction;
Viii. backfill.
Precast splice type cable active well provided by the invention and job practices thereof, it is little effectively to have overcome existing round drawer formula structure precast splice type active well shape choice, is difficult to the deficiency of the needs of various active wells in the appropriate cable construction.
Description of drawings
Fig. 1 is the structural representation of precast splice type cable active well provided by the invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the precast splice type cable active well can be approximate rectangular build, square build or dome gallery type; Cable work well comprises prefabricated component blocks, seal 7 and bolt group 8; Described prefabricated component blocks comprises two termination upper member pieces 1, two termination lower member pieces 1 ', four changeover portion upper member pieces 2, four changeover portion lower member pieces 2 ', two well head section upper member pieces 3, well head section lower member piece 3 ', well head section lower member piece 5, ponding well building block 6, changeover portion upper member piece 4, a changeover portion lower member piece 4 '; Height after each upper and lower building block stack of matching mutually is the height of well body; In order to improve the splicing intensity of active well, the vertical height of adjacent building block is different in the horizontal direction, be that termination upper member piece 1 is unequal with changeover portion upper member piece 2 vertical heights, changeover portion upper member piece 2 and well head section upper member piece 3, changeover portion upper member piece 4 vertical heights are unequal, termination lower member piece 1 ' is unequal with changeover portion lower member piece 2 ' vertical height, changeover portion lower member piece 2 ' and well head section lower member piece 3 ' and 5, changeover portion lower member piece 4 ' vertical height is unequal, makes the horizontal direction seam of adjacent building block up and down not be on the same horizon thus.The seam crossing that all prefabricated component blocks are spliced mutually all is lined with seal 7; Connect with bolt group 8 between the prefabricated component blocks.If need to change well body longitudinal length, can realize by the upper and lower building block of increase and decrease changeover portion.
Present embodiment is constructed with method as follows:
I. cable work well bracing of foundation pit construction;
Ii. excavation of foundation pit;
Iii.C10 plain concrete cushion layer 9 is built;
Iv. at the impervious processing coating of the native face brushing of meeting of prefabricated component blocks concrete surface, paste the hydro-expansive rubber waterstop;
V. by getting on, get off, order assembly unit prefabricated component blocks is from front to back put seal 7 at the seam crossing pad of contiguous prefabricated building block again, connects each prefabricated component blocks with bolt group 8;
Vi. cut off the prefabricated component blocks drop hanger, mend the impervious processing coating of brush concrete surface at former drop hanger position;
Vii. cable duct bank interface construction;
Viii.. backfill.
