Construction method for filling intercommunication ramps with foam light soil
The invention discloses a construction method for filling an intercommunication ramp by using foam light soil. The construction method comprises the following steps: (1) preparing cement paste; 2) preparing foam; (3) preparing foam light soil; (4) preparing a pouring area site; (5) casting foam light soil in situ, using the bottommost layer as the first layer for pouring, and arranging pouring areas every 10-15 m in the longitudinal direction of the roadbed; after slope excavation is completed, performing sequential construction from the bottom layer to the upper layer in a layered mode during filling, the single-layer pouring thickness is controlled to be 60 cm, the top layer pouring thickness is controlled to be 0.3-1.0 m according to the designed elevation, and when pouring is conducted towards the upper layer, performing 90 cm construction; filling the edge covering lime soil layer by layer from bottom to top according to the ultra-width of 1 m, the compaction degree meets the design requirement, and after the edge covering lime soil is filled to the top elevation, performing slope brushing on the edge covering lime soil; performing roadbed lime soil filling after the strength of the foam light soil meets the requirement, performing filling layer by layer, the compaction degree meets the design requirement, and adjusting transverse and longitudinal slopes of a roadbed; and 6), performing maintenance, according to the method, the load of the roadbed base can be obviously reduced, post-construction settlement of the roadbed is eliminated, and the diseases such as bumping at the bridgehead are solved.
本发明公开了一种利用泡沫轻质土填筑互通匝道的施工方法，包括：1）水泥浆制备；2）泡沫制备；3）泡沫轻质土制备；4）浇筑区场地准备；5）现浇泡沫轻质土，以最底层作为浇筑的第1层，沿路基纵向每隔10~15m设置一个浇筑区；边坡开挖完成后，填筑时从底层往上分层依次施工，单层浇筑厚度以60cm控制，顶层根据设计高程浇筑厚度控制在0.3~1.0m，往上层浇筑时横向收90cm；包边灰土按超宽1米，从下往上逐层填筑，压实度满足设计要求，填筑到顶标高后，再对包边灰土进行刷坡；路床灰土填筑应在泡沫轻质土强度满足要求后进行，逐层填筑，压实度满足设计要求，并调整路基横纵坡；6）养护。本发明可显著减轻路基基底荷载，消除路基工后沉降，解决桥头跳车等病害。
