Method for heightening and reinforcing gravity retaining wall
The invention belongs to the field of geotechnical engineering design and construction, and particularly relates to a heightening and reinforcing method for a gravity type retaining wall, which comprises the following steps: S1, arranging vertical steel pipe piles: excavating and leveling a wall toe top elevation section with elevation lower than that of the gravity type retaining wall on a site, arranging two rows of vertical drill holes, a row of vertical drill holes close to the gravity type retaining wall penetrate through a wall toe of the gravity type retaining wall, vertical steel pipes are placed in the two rows of vertical drill holes, and grouting is conducted in the vertical steel pipes; s2, inclined steel pipe piles are arranged, specifically, a row of inclined drill holes are formed from the position between the two rows of vertical drill holes to the position below the wall toe of the gravity type retaining wall, inclined steel pipes are put down in the inclined drill holes, and grouting is conducted in the inclined steel pipes; s3, a crown beam is poured on the tops of the two rows of vertical steel pipe piles and the top of the row of inclined steel pipe piles; and S4, a soil retaining plate is poured below the top beam and on the sides of the two rows of vertical steel pipe piles. The heightening and reinforcing method is easy and convenient to construct and low in engineering cost, and the overall stability of the gravity retaining wall is improved.
本申请属于岩土工程设计与施工领域，尤其涉及一种重力式挡土墙的加高加固方法，包括以下步骤：S1.设置竖向钢管桩：在场地开挖整平标高低于重力式挡土墙的墙趾顶部标高段，布置两排竖向钻孔，靠近重力式挡土墙的一排竖向钻孔穿过重力式挡土墙的墙趾，在两排竖向钻孔内下放竖向钢管并在竖向钢管内注浆；S2.设置斜向钢管桩：从两排竖向钻孔之间向重力式挡土墙的墙趾下方布置一排斜向钻孔并在斜向钻孔内下放斜向钢管，在斜向钢管内注浆；S3.在两排竖向钢管桩和一排斜向钢管桩的顶部浇筑一道冠梁；S4.在冠梁的下方和两排竖向钢管桩的侧方浇筑一挡土板。该加高加固方法施工简便、工程造价低，提高重力式挡土墙的整体稳定性。
