Novel grouting method for grouting corrugated pipe
The invention provides a novel grouting method for grouting corrugated pipes. The novel grouting method comprises the steps that grouting holes and a plurality of grouting corrugated pipes are reserved before construction of a bent cap; the plate-type reinforcing steel bar protection structure is arranged in the grouting hole, and the plate-type reinforcing steel bar protection structure is rotated in the direction perpendicular to the main reinforcements in the grouting hole so that the metal grooves in the plate-type reinforcing steel bar protection structure can be connected with the corresponding main reinforcements in the grouting hole in a clamped mode; before the bent cap and the pier column are positioned and assembled, the mortar leveling layer at the bottom of the sealed bent cap, and the grouting hole and the grouting corrugated pipe are communicated through the mortar leveling layer; the bent cap and the pier column are positioned and spliced; and after it is confirmed that the mortar leveling layer is sealed, the plate-type steel bar protection structure is taken out, grouting is conducted on the grouting holes, and slurry is diffused into the grouting corrugated pipes from the mortar leveling layer through the grouting holes and fills the grouting corrugated pipes from bottom to top. According to the method, grouting corrugated pipes are synchronously grouted from bottom to top according to the communicating vessel principle, the grouting efficiency is improved, and the connection strength and integrity of grouting corrugated pipe connection are improved.
本申请提供一种灌浆波纹管新型灌浆方法，其包括在盖梁施工前预留灌浆孔和多个灌浆波纹管；将板式钢筋保护结构置于灌浆孔内，沿垂直于灌浆孔中主筋方向转动板式钢筋保护结构，以使板式钢筋保护结构上的金属凹槽与灌浆孔中相对应的主筋相卡接；在盖梁和墩柱定位拼装前，密封盖梁底部的砂浆调平层，灌浆孔和灌浆波纹管通过砂浆调平层相连通；将盖梁与墩柱定位拼接；确认砂浆调平层密封后，将板式钢筋保护结构取出并向灌浆孔中注浆，浆料通过灌浆孔再由砂浆调平层扩散至各个灌浆波纹管中，并由下至上填满灌浆波纹管。该方法利用连通器原理自下而上同步向各灌浆波纹管注浆，提高注浆效率，提高灌浆波纹管连接的连接强度和整体性。
