Abstract
The utility model discloses a power cable trough hand hole well. The power cable trough hand hole well comprises a well body composed of a bottom plate and a well wall arranged on the side of the bottom plate. The upper end of the well body is closed through a cover plate, a communication signal cable trough is formed in the well body and in the inner side of the transverse well wall on one side, a gap is reserved between the communication signal cable trough and the bottom plate and is communicated with a cable rail-passing pipeline arranged at the lower end of the transverse well wall, and communicated power cable inlets are formed in the vertical side walls on the two sides of the well body. The communication signal cable trough, the cable rail-passing pipeline, and the power cable inlets are independently arranged inside the power cable trough hand hole well, so that mutual interference of electromagnetism is avoided. The space inside the well can meet the requirement of power cable connection equipment and manual operation space and provide effective protection for electrical equipment and does not influence the width of the subgrade surface, the subgrade strength, the stability and the safety of a ballastless track, and therefore the power cable trough hand hole well is applied to the subgrade of the ballastless track of a high-speed railway.
Description
Technical field
The utility model relates to technical field of civil engineering, refers to particularly a kind of Cable Groove hand hole well being applied in ballastless track of high-speed railway roadbed.
Background technology
In China Express Railway system, stand after " four electricity " (four electricity refer to: traction power supply, equipment power supply, communication cable, signal cable) engineering as a subsystem, it may be subject to the various pipelines of environmental disturbances and connection, difference and the maintenance of pipeline, maintenance facility, all hidden, bury underground in online lower engineering, and with line under engineering synchronous construction, be referred to as: railway bed with station after " four electricity " interface.
At present, railway bed has become with the Interface design of rear " four electricity " the engineering ancillary structure in station the important composition content that high-speed railway subgrade designs, in ballastless track roadbed and the design of ad eundem railway bed, all should consider to bury underground in advance " four electricity " cable tank circuit in roadbed, for the hand hole well of cable construction, maintenance and cable across roadbed, cross rail facility.Because rear " four electricity " the engineering design technology deposit in China Express Railway track base without broken stones and station is still incomplete, the Interface Engineering of built or complete design, the form of structure of its Cable Groove hand hole well and interior space dimension, standard disunity, and all fail to meet completely the requirement of each relevant speciality.At present promulgated practical Environment in Railway Engineering Construction generalized reference atlas figure number: in path (2010) 8401, in Cable Groove hand hole well, communication, signal cable adopt embedded bar bracket to pass in holder extension mode, communication, signal cable are exposed in power cable well, also do not meet strong, weak electricity cable and divide groove to lay requirement.
Therefore, need improve prior art.
Summary of the invention
The purpose of this utility model is exactly that a kind of Cable Groove hand hole well being applied in ballastless track of high-speed railway roadbed will be provided, to solve the problem in background technology.
The technical solution of the utility model is: a kind of Cable Groove hand hole well, it comprises by base plate and is arranged on the well bore that the borehole wall on base plate limit forms, described well bore upper end is by cover plate capping, it is characterized in that: in described well bore, be provided with communicaton and signal cable groove, described communicaton and signal cable groove is arranged on the horizontal borehole wall inner side of a side, between communicaton and signal cable groove and base plate, be provided with space, described space is crossed rail pipeline with the cable that is arranged on described horizontal borehole wall lower end and is communicated; The vertical side walls of described well bore both sides is provided with the power cable entrance communicating.
In such scheme:
Described space, by Concrete Filled, is provided with in described concrete with cable and crosses the through hole that rail pipeline communicates.
The horizontal borehole wall of described opposite side offers cable leading and goes out roadbed preformed hole, and described cable leading goes out roadbed preformed hole and crosses the corresponding setting of rail pipeline with cable.
Described communicaton and signal cable groove is L-type.
Described borehole wall lower end is provided with the spilled water hole of a plurality of spaced sets, in described spilled water hole, is provided with pvc pipe.
The described borehole wall offers seam, and described cover plate lid is located on seam.
Independently be provided with communicaton and signal cable groove in the utility model, cable is crossed rail pipeline and power cable entrance, to avoid the mutual interference of electromagnetism phase.In well, space can meet power cable connection device and manual operation space simultaneously, and provide effective protection for electric fixtures, and not affecting ballastless track roadbed face width degree, subgrade strength and stability and safety, is a kind of Cable Groove hand hole well being applicable in ballastless track of high-speed railway roadbed.
Accompanying drawing explanation
Fig. 1 is schematic cross section of the present utility model;
Fig. 2 is flat generalized section of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of Cable Groove hand hole well as shown in Figure 1 and Figure 2, it comprises by square floor 6 and is arranged on the well bore 2 that the borehole wall 1 on base plate 6 limits forms, in well bore 2, be that power cable dish line, equipment are settled and manual operation district, the interior bulk of well bore 2 need meet power cable annular disk embroidery, reserved redundant length and equipment is settled, manually-operated needs; Well bore 2 upper ends are by cover plate 5 cappings, cover plate 5 is formed by concreting, in well bore 2, be provided with communicaton and signal cable groove 2.1, communicaton and signal cable groove 2.1 is arranged on the horizontal borehole wall 1 inner side of a side, and communicaton and signal cable groove 2.1 waters and builds up integral body with the horizontal borehole wall of this side; Between communicaton and signal cable groove 2.1 and base plate 6, be provided with space, described space is crossed rail pipeline 3 with the cable that is arranged on the described horizontal borehole wall 1 lower end and is communicated; The vertical side walls of well bore 2 both sides is provided with the power cable entrance 2.2 communicating.
In the present embodiment:
Space between communicaton and signal cable groove 2.1 and base plate 6 is filled by concrete 3.2, is provided with cable and crosses the through hole that rail pipeline 3 communicates in concrete 3.2.The concrete of filling not only can play to communicaton and signal cable groove 2.1 effect of support, can also strong, weak electricity cable with armored concrete slab, separate, to avoid the mutual interference of electromagnetism phase.
