The utility model provides a technical scheme that above-mentioned problem adopted is: a tower anchor pier integrated pedestrian suspension bridge comprises a main cable, a loose cable sleeve, a loose cable strand, a sling, a main beam, a support, an anchor tower and an anchor pier; the method is characterized in that: the anchor tower is fixedly arranged on the anchor pier, the anchor tower and the anchor pier are eccentrically arranged, and the anchor tower tilts backwards relative to the anchor pier; the cable scattering sleeve is arranged at the end part of the main cable, the cable scattering sleeve scatters the end part of the main cable into a plurality of cable scattering strands, and the cable scattering strands are anchored at the upper part of the anchor tower; a support is arranged on the top surface of the anchor pier; the sling is arranged on the main cable; the main beam is suspended on the sling, and the end part of the main beam is supported on the support.
The cross section of the anchor pier is a rectangular section.
The cross section of anchor tower be the rectangular section.
The utility model discloses be provided with anchor pier haunches at the combination position of anchor pier and anchor tower.
Many scattered rope strand resultant force action point be located the longitudinal axis of anchor tower.
The girder divide into a plurality of sections, hang respectively on the hoist cable, the section one end of last girder hangs on the hoist cable, the other end supports on the support.
Compared with the prior art, the utility model, have following advantage and effect: the utility model discloses utilize dead weight of anchor tower and anchor pier to come balanced main cable power, replace traditional anchor span and anchorage through setting up anchor pier and anchor tower, greatly reduced engineering quantity, construction cost and the construction degree of difficulty, also can not produce too much destruction to massif natural environment, the comparatively complicated condition of specially adapted mountain area geology topographic condition.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.
The embodiment of the utility model provides an including main push-towing rope 1, loose cable cover 11, loose cable strand 12, hoist cable 2, girder 3, support 31, anchor tower 4, anchor pier 5 and anchor pier haunches 51.
The anchor piers 5 are fixedly arranged on the mountain bodies at two ends. The cross section of the anchor pier 5 is a rectangular section.
The anchor tower 4 is fixedly arranged on the anchor pier 5, the anchor tower 4 and the anchor pier 5 are eccentrically arranged, the anchor tower 4 tilts backwards relative to the anchor pier 5, and the purpose is to balance the horizontal component force of the main cable 1 by utilizing the gravity of the anchor tower 4, so that the anti-overturning moment of the anchor pier 5 and the anchor tower 4 is improved. The cross section of the anchor tower 4 is rectangular, and the width of the transverse bridge direction is the same as that of the anchor pier 5.
The anchor pier haunching 51 is arranged at the joint part of the anchor pier 5 and the anchor tower 4, and the anchor pier haunching 51 can smoothly transmit the horizontal force and the vertical force of the anchor tower 4 to the anchor pier 5, so that the connection part of the anchor tower 4 and the anchor pier 5 is not subjected to stress concentration and is damaged, and the structural stress is more reasonable.
