Detailed description of the invention
Below with reference to drawings and Examples, technical solution of the present invention is further described:
Shown in accompanying drawing 1 ~ 10, the implementation step of the method for the supporting of slope protection pile inter-pile soil described in technical solution of the present invention is:
Step one, employing common process carry out the construction of slope protection pile 4, the horizontal section of slope protection pile 4 is cylinder, rectangle or square, when 1 colligation of slope protection pile reinforcing cage, first preset in reinforcing cage 1 side (side slope longitudinally) the packed column block 2 being easy to that the later stage rejects, using the flexible material such as polyphenyl plate, extruded sheet shaping, not easily should be there is moderate finite deformation by the concrete compression that the later stage pours in packed column block 2 itself, and firm with reinforcing cage 1 colligation, prevent from locating misalignment, the later stage picks cutter difficulty.Binding material can be steel wire, also can for having the ordinary lines, rope etc. of some strength.The top of packed column block 2 can to the top of reinforcing cage 1, when having hat beam, can to hat beam lower limb, and packed column block 2 lower end should lower than lower than design toe more than absolute altitude 200mm; For in temporary work time, the width of packed column block 2 is generally 50mm ~ 100mm, in permanent work time, according to the difference of stake diameter, spacing etc., the width of packed column block 2 is generally 100mm ~ 500mm; After the boring of pile foundation completes, the reinforcing cage entering to make under in hole, then concreting (when adopt to insert reinforcing cage after drilling & grouting piling concrete time, the two is out of order), the space that relative flexibility material occupies, concrete can not enter, and this also facilitates the rejecting in later stage.Reinforcing cage 1 with packed column block 2 fluid concrete after the shaping slope protection pile 4 of maintenance in stake holes 3, the earthwork step excavation of side slope or foundation ditch can be carried out, now, the concrete of filling block 2 and part attachment can be removed by substep simultaneously, thus a groove 5 is formed on the opposite flank of two adjacent slope protection pile 4, groove 5 is parallel with reinforcing cage 1 center line 10, and the degree of depth of this groove 5 exceedes the position of the reinforcement stirrup 6 of reinforcing cage 1 inner ring and reaches 80mm ~ 300mm.
