Description
Technical field
The present invention relates to a kind of construction method of utilizing downtown roads to lay the road slot minitype communication pipe, belong to technical field of cable transmission.
Background technology
The construction of conventional cable transmission network, at first broken road ditching on downtown roads or walkway is embedded in communication pipe underground, by the mode of artificial traction, lays ordinary optical cable in pipeline again.
Existing road groove optical cable construction mode is to leave a narrow slit on the downtown roads road surface, buries in the slit and puts an optical cable.Though this form of construction work has short, the advantage flexibly of building time, because road groove system of laying is disposable, installs gradually with the little cable of air-blowing and compare, for later network capacity extension reduction with the obvious advantage, and when breaking down, optical cable is difficult for changing.
The existing micro-control push pipe mode that is used for road groove optical cable laying, owing to be subjected to the influence of complicated subterranean pipe line when constructing in the city, its application is restricted, and there is weak point in the detectivity of micro-control pipe jacking equipment, makes the operation of micro-control push pipe have very big danger.
Road groove microchannel is on downtown roads, across or along road, adopt cast-cutting saw, narrow groove of cutting makes up microchannel in groove on road.
Summary of the invention
The objective of the invention is to propose a kind of construction method of utilizing downtown roads to lay the road slot minitype communication pipe, make the construction of communication pipe in the city convenient more, destruction to original road and urban operating mechanism when communication pipe is laid is reduced to negligible degree, but also not connected people (hand) hole can be interconnected.Provide support for setting up the optical cable Metropolitan Area Network (MAN), the end of Metropolitan Area Network (MAN) is linked in the communication microchannel very easily.
The downtown roads that utilize that the present invention proposes are laid the construction method of road slot minitype communication pipe, may further comprise the steps:
(1) according to setting the planning or the design route picture ditch line of rabbet joint,, digs out groove, and make channel bottom smooth along the ditch line of rabbet joint cutting road surface of finishing;
(2) bury at an end of groove and put four-way or threeway microtubule difference box, the other end of groove buries near manhole or cross-connecting box place puts the microtube joint box;
(3) spread fine sand at described channel bottom, thickness is 5～15 millimeters, and the conduit saddle that tiles on fine sand is placed on little cable pipe cloth on the conduit saddle in the groove, and makes little cable manage two ends to stretch into respectively in microtube joint box and the microtubule difference box;
(4) put shroud above the sub-pipe in groove, shroud and following slit are filled up with fine sand, at last cover plate is covered on shroud;
(5) remove loose material, dust or mud in the groove, in groove, pour instant coagulant and mending agent into, smooth until the groove periphery.
In the said method, the width w of groove is 40～60 millimeters, and the degree of depth h of groove is 200～300 millimeters.
The downtown roads that utilize that the present invention proposes are laid the construction method of road slot minitype communication pipe, and its advantage is:
1, having wide range of applications of the inventive method, the end that can be used for Metropolitan Area Network (MAN) inserts, and links up existing communication pipeline and tubule footpath rain (dirt) waterpipe and makes up replenishing of microchannel system.
2, compare with existing road groove optical cable, owing to adopt the little cable of microtubule, the network capacity extension is with the obvious advantage, and during Cable's Fault, repairing is easy, and recovery communication is fast.
3, compare with existing micro-control push pipe mode, construction is not limited by underground pipe network flexibly, and construction is dangerous minimum.
