Background technology
Along with China's wind power industry is rapidly developed, Wind turbines single-machine capacity is increasing, runner diameter is increasing, hub height is more and more higher.The supporting construction of traditional Wind turbines is steel cone tower, sectional making, it is connected with, steel tower has good looking appearance, feature easy for installation, but along with the development of Wind turbines maximization, for meeting stress and rigidity needs, the diameter of steel tower is increasing, when hub height is more than 100m, the diameter of its end section tower is considerably beyond the arrowhead of conventional highway transportation, thus limits the development that Wind turbines maximizes.
The problem of transport difficult for solution large-scale wind electricity unit steel tower diameter is excessive, need to reduce the height of steel tower, bottom tower will be changed into concrete tower by steel tower, and top tower still uses the steel tower of routine, the steel tower on top reduces due to height reduction, stress, and its diameter just can meet the requirement of conventional highway transportation.The concrete tower of bottom is owing to diameter is big, weight big, and complicated construction technique, concrete tower is in addition to needs meet structural strength and rigidity requirement, in addition it is also necessary to can transport easily and install, and reduce investment outlay.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, it is provided that a kind of construction technology is simple, transport and easy for installation, cheap sectional prefabricating type concrete tower.
This utility model be the technical scheme is that a kind of sectional prefabricating type concrete tower, including base foundation and the overall concrete tower tapered in round platform, concrete tower upper end is connected to the steel tower matched with its diameter, it is characterized in that described concrete tower is spliced by the prefabricated tower segments of several horizontal fragmentations, all it is preset with in each prefabricated tower segments and in base foundation and is mutually aligned up and down and the prestress wire poling of rounded distribution, in poling elongated wear prestress wire and in the top and base foundation of concrete tower after stretch-draw anchor.
The wall thickness of described each prefabricated tower segments is 300~500mm, and each section of centre in addition to top section is with the prefabricated tower segments of end section is truncated cone-shaped;The side view of the prefabricated tower segments of top section is circular arc, and top is provided with the anchor of prestress wire, and top outer is provided with maintenance and mounting platform;The prefabricated tower segments of end section is connected with base foundation, and is provided with the door entered within tower.
Described base foundation bottom is provided with the anchoring operation hole of the prestress wire corresponding with prestress wire poling.
The unilateral tapering of described concrete tower is between 0.1~0.2, and its strength grade of concrete is between C40~C70.
Described prestress wire poling is PE pipe or pvc pipe.
The beneficial effects of the utility model are:
1, this utility model uses the concrete tower of sectional prefabricating type, and the construction quality of precast concrete is preferable, intensity can be guaranteed, and the size of each segmentation, weight are less, in that context it may be convenient to transport and install, and cost is relatively low.
2, segmented mode of the present utility model is horizontal fragmentation, does not carry out vertical section, the prefabricated tower segments negligible amounts that such segmented mode is formed, and each section is overall frustum cone structure, it is simple to lifts and splices.
3, prestress wire poling is preset in prefabricated tower segments of the present utility model so that the strength and stiffness of whole concrete tower can be effectively guaranteed.
4, this utility model arranges the anchor of prestress wire at the top of the top prefabricated tower segments of section, arranges the anchoring operation hole of prestress wire in foundation bottom, it is simple to the stretch-draw of prestress wire and anchoring operation.

Detailed description of the invention
As shown in figures 1-4, the present embodiment is a sectional prefabricating type concrete tower high for 30m, including base foundation 2 and the overall concrete tower 1 tapered in round platform, concrete tower upper end is connected to the steel tower joined with its diameter phase region, concrete tower 1 is spliced by prefabricated tower segments 1-1 of 6 horizontal fragmentations, all it is preset with in each prefabricated tower segments 1-1 and base foundation 2 and is mutually aligned up and down and the prestress wire poling 3 of rounded distribution, in this poling elongated wear prestress wire 4 and in the top of concrete tower 1 and base foundation 2 after stretch-draw anchor.
In the present embodiment, concrete tower 1 is spliced by prefabricated tower segments 1-1 of 6 horizontal fragmentations, and overall in truncated cone-shaped after splicing, unilateral tapering is between 0.1~0.2, and this example is 0.1;A diameter of 4.0m of this tower upper end, is connected to the steel tower matched with its diameter, and the diameter of lower end (according to stress it needs to be determined that) is 10.0m, is connected with base foundation 2.Prefabricated tower segments 1-1 each section of centre in addition to top section is with end section is truncated cone-shaped, and its wall thickness is between 300mm~500mm, and this example is 400mm;The prefabricated tower segments of top section is to adapt to the bending of prestress wire, and its side view is circular arc, and arc radius is 60m, and the top of the prefabricated tower segments of top section is provided with the anchor 5 of prestress wire, and outside is provided with maintenance and mounting platform 6;The prefabricated tower segments of end section is connected with base foundation 2, and is provided with the door entered within tower.
Each prefabricated tower segments 1-1 is all prefabricated on ground, and its strength grade of concrete is between C40~C70, and this example is C60;Time prefabricated, stack shell arranges conventional nonprestressed reinforcement.Being preset with the prestress wire poling 3 being mutually aligned up and down in each section of prefabricated tower segments 1-1 and base foundation 2, this prestress wire poling is PE pipe or pvc pipe, and this example is PE pipe.Arrange the anchoring operation hole 2-1 of prestress wire 4 in base foundation 2 lower end, the lower end of prestress wire anchors in anchoring operation is cheated.
The present embodiment is by after prefabricated for all of prefabricated tower segments 1-1 completing, use the mode Piecemeal erection of lifting, in prestress wire poling 3, prestress wire 4 is worn after all installing, before prestress wire poling, outside needs oiling, prestress wire 4 poling post-stretching, and its upper and lower end is anchored in anchor 5 and anchoring operation hole 2-1.
