Abstract
The utility model relates to an optical cable lays technical field, discloses an optical cable lays structure for conduit. The water delivery pipe comprises a water delivery pipe body, wherein the water delivery pipe body comprises an internal application section, a sleeve is arranged on the internal application section, the sleeve is arranged in the water delivery pipe body along the axial direction of the water delivery pipe body, and through holes which are respectively connected with two ends of the sleeve in a sealing mode are formed in the wall of the water delivery pipe body. The sleeve is arranged in the internal laying section of the water pipe, and then the optical cable is arranged in the sleeve, so that the optical cable can be laid conveniently under complex geological conditions; the utility model discloses simple structure, the installation degree of difficulty is little, reduces the optical cable and lays the cost, avoids adopting the directional drilling precision low problem that the push pipe method construction brought, reduces because the construction environment is complicated or the risk of obviously bringing.
Description
Technical Field
The utility model relates to an optical cable lays technical field, especially relates to an optical cable lays structure for conduit.
Background
At present, relevant valves can be arranged along large-scale long-distance water delivery steel pipes in China, valves are convenient to automatically control, corresponding communication optical cables can be laid along the way in water delivery pipeline construction, a conventional grooving and pipe burying construction section can be laid along with the water delivery steel pipes in a burying and synchronizing mode, when the burying project needs to cross existing buildings, the water delivery steel pipes are generally constructed by a pipe jacking method, the optical cables are laid by directional drills, but the directional drills are low in precision, construction difficulty can be increased for complex geological conditions, other complex conditions can exist for underground buried objects, for example, important equipment such as military optical cables, gas or oil delivery pipelines can be buried, and safety risks exist in the process of construction by the directional drills under the condition that the burying conditions of the underground buried objects cannot be accurately identified.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem provide an optical cable lays structure for conduit, be convenient for lay at the optical cable under the complicated geological conditions condition.
The utility model provides a technical scheme that its technical problem adopted is: a optical cable laying structure for conduit, including the raceway, the raceway includes the interior section of applying, and the interior section of applying is provided with the sleeve pipe, and the sleeve pipe sets up in the raceway along raceway axial direction, and the raceway pipe wall is provided with the through-hole with sheathed tube both ends sealing connection respectively.
Further, the method comprises the following steps: the sleeve pipe is provided with the flexion near through-hole one side, and the crookedness of flexion is less than the maximum crookedness of optical cable.
Further, the method comprises the following steps: the through hole is oval.
Further, the method comprises the following steps: the inner diameter of the sleeve is matched with the outer diameter of the laid optical cable.
Further, the method comprises the following steps: the sleeve is welded with the water pipe at the through hole.
The utility model has the advantages that: the sleeve is arranged in the internal laying section of the water pipe, and then the optical cable is arranged in the sleeve, so that the optical cable can be laid conveniently under complex geological conditions; the utility model discloses simple structure, the installation degree of difficulty is little, reduces the optical cable and lays the cost, avoids adopting directional boring construction precision low on the one side problem to appear, reduces because the construction environment is complicated or the risk of obviously bringing.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic top view of the through hole of the present invention;
labeled as: a water pipe 1, a sleeve 2 and a through hole 3.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, the optical cable laying structure for a water pipe of the present invention comprises a water pipe 1, the water pipe 1 comprises an internal laying section, the internal laying section is provided with a sleeve 2, the sleeve 2 is arranged in the water pipe 1 along the axial direction of the water pipe 1, and the pipe wall of the water pipe 1 is provided with through holes 3 which are respectively connected with two ends of the sleeve 2 in a sealing manner; the sleeve 2 is provided with a bending part on one side close to the through hole 3, and the bending degree of the bending part is smaller than the maximum bending degree of the optical cable.
When facing the complicated condition of construction geological conditions, in order to reduce the construction risk and the construction difficulty of laying the optical cable, set up the interior section of applying on raceway 1, set up the optical cable in sleeve pipe 2. The setting of 2 flexion of sleeve pipe is decided according to the maximum crookedness that the optical cable that lays can bear, ensures that the optical cable can normally be installed, does not influence operating condition.
Specifically, as shown in fig. 1 and 2, the through hole 3 is oval, and the matching surface of the sleeve 2 on the pipe wall of the water pipe 1 is oval, so that the bending degree of the optical cable during installation is reduced.
Specifically, the inner diameter of the sleeve 2 is adapted to the outer diameter of the laid optical cable.
Specifically, sleeve pipe 2 and raceway 1 are in through-hole 3 department welded connection, and the welding is accomplished the back and is carried out ultrasonic inspection and detect to the welding seam, and unqualified need carry out repair welding, guarantees that the two is sealing connection state, avoids the water overflow in raceway 1 to leak out.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
