The major technique innovative point
One, the construction period is short, the investment return ratio is high
Owing to the mountain area population decentralization, have inconvenient traffic, the unit telephone traffic is low, in recent years, because the host support price descends, the base station construction cost also descends year by year, but the construction of original communication shaft tower is because raw material appreciate, artificial and cost of transportation rises, and the shared proportion of construction investment is more and more higher.Reaching under the situation of identical coverage effect, 18 meters high isometrical shaft towers obviously have the investment return ratio that is higher than other communication tower because the construction period is short, cost is low.
Two, the scope of application is wide
The construction of 18 meters bars can be suitable for multiple geological condition.Generally confirm that at the scene place width and on-site soil are not the rock stratum that can't excavate fully, other soil property situation, for example: weak saprolite such as sand, loess, cohesive soil, middle saprolite, severely-weathered soil all can be built.This tower capital construction is comparatively simple, and the cement chassis of building one 1 meter * 1 meter 18 meters bar bottoms is aided with 8 backguys again and just can makes the body of rod satisfy the requirement of safe handling with the power of holding.Through design accounting: the maximum wind pressure that 18 meters cement pole structures can bear is 0.8KN/m
2, the blast in most of area, area, Sanming City has only 0.4KN/m
2, 18 meters bars can be similar to Sanming City this landlocked mountain area use in a big way.
Three, low to the job site conditional request
The construction of 18 meters bars is lower to the job site conditional request, has just catered to the remote mountain areas demand of building a station with a varied topography.It is as long as the scene provides a place can carry out the welding of 6 meters bodies of rod of 3 joints, and base station, the nearly all mountain area of this condition can be satisfied.
Four, applicability is strong
Through body of rod Structure Calculation, 18 meters bars can be supported two-layer platform up and down, and every layer of platform is by two secondary whippletree square crossings, every layer of platform can be supported 4 slave antennas, can support at most 8 slave antennas are installed, and the antenna mounting means is flexible, both can have supported omnidirectional antenna also can support the installation of directional antenna.
Five, easy to maintenance
Tower compared to other type needs whole body of the tower is carried out the integral body maintenance, it is comparatively simple and easy that the maintenance of 18 meters bars just shows, generally speaking, only need be the hardware except that the cement body of rod every the member of periodic maintenance half a year, and the weld seam of the body of rod, as long as regularly these members are carried out anticorrosion processing of rust removing, guarantee that the situation that relaxes, comes off does not appear in the junction, and the operating position of making regular check on backguy just can guarantee that the safety of 18 meters isometrical bars normally uses.And the simple and easy cat ladder on body of rod limit helps attendant's upper boom to carry out the maintenance of the body of rod and platform, also is convenient to the dismounting and the adjustment of antenna.(annotating: need carry out supplementary maintenance when standing typhoon weather or natural calamity and might jeopardize tower body safety).
