Description

A kind of prestressed anchor cable pile sliding wall along river road shoulder

Technical field

The utility model relates to the high embankment retaining structure in mountain highway, the railway engineering building field, relates in particular to a kind of prestressed anchor cable pile sliding wall along river road shoulder.

Technical background

In present highway, railway construction, the high embankment highway section retaining structure of part engineering adopts the anchored pile board wall.The anchored pile board wall is applicable to that embankment highly is in the filled-up ground of 12～20m, and it is littler, rational in infrastructure than general retaining wall volume, and cost is lower than bridge, is the light-duty retaining structure of a kind of flexibility.Load for the ease of anchor cable stretch-draw on pile body, the pile body of present anchored pile slab-wall structure is the side's of employing stake form usually, and adopts manually digging hole method pore-forming.

After the breast boards of separate type retaining wall generally directly was positioned over the rib post at present, the soil body was relatively large to the active force of breast boards, causes the arrangement of reinforcement of breast boards more.The anchored pile slab-wall structure is in order to bring into play the acting in conjunction of piled anchor at present, and the spacing of anchor cable is generally 3～4m, and the spacing of anchor cable in geotechnical body is less than normal, and " group's anchor effect " takes place easily.

Summary of the invention

The purpose of this utility model is the shortcoming and defect that exists at prior art, and a kind of prestressed anchor cable pile sliding wall along river road shoulder is provided.

The purpose of this utility model is achieved in that

The utility model is at the roadbed groundwater table is higher relatively along the river, and the extremely difficult situation of manual pore-forming is adopted in the stake hole, and the structure of general anchored pile board wall is improved.Concrete is changes the fixed section of pile body into the circle stake by side's stake, adopts mechanical hole building; Top rib post adopts T type post; Middle part part adopts the coupling beam structure, and the soil body partly is delivered to the circle stake to the active force of rib post;

The utility model increases by two edges of a wing in the both sides of square rib post, and the rib post behind the increase edge of a wing is T type structure.T type post had both helped the overlap joint of breast boards, increased width of subgrade effectively, also can give full play to " soil arching effect " of rib post simultaneously, reduced the active force of the soil body to breast boards, thereby arrived the purpose of the arrangement of reinforcement that reduces breast boards.

The utility model adopts different inclination angles to be anchored in the geotechnical body anchor cable, has increased the spacing of anchorage cable anchoring section, can reduce the probability that " group's anchor effect " takes place anchor cable effectively.

Specifically, this prestressed anchor cable pile sliding wall along river road shoulder comprises circle stake, coupling beam, T type post, breast boards, anchor cable and anchor pier;

From top to bottom, circle stake, coupling beam are connected successively with T type post;

Be placed with breast boards in per two T type post inboards;

On T type post, be respectively arranged with three anchor piers in upper, middle and lower from top to bottom;

The three anchorage cable anchoring sections in upper, middle and lower anchor in the rock-soil layer, and anchor cable carries out stretch-draw, locking to anchor cable after passing preformed hole on the T type post on corresponding anchor pier;

The inclination angle of three anchor cables in upper, middle and lower is designed to 15 °, 18 °, 21 ° respectively.

The utility model has following advantage and good effect compared with prior art:

1, the utility model improves general anchored pile slab-wall structure, thereby make it to be suitable for a retaining of high-fill roadbed along the river, both sides at the square rib post increase by two edges of a wing, rib post behind the increase edge of a wing is T type structure, T type post had both helped the overlap joint of breast boards, increased width of subgrade effectively, can give full play to " soil arching effect " of rib post simultaneously again, reduce the active force of the soil body, thereby arrive the purpose of the arrangement of reinforcement that reduces breast boards breast boards;

2, anchor cable adopts different inclination angles to be anchored in the geotechnical body, has increased the spacing of anchorage cable anchoring section, can reduce the probability that " group's anchor effect " takes place anchor cable effectively.

In a word, the utility model is rational in infrastructure, implements easily, and is best in quality, is applicable to the prestressed anchor cable pile sliding wall along river road shoulder construction.
