Mass concrete body surface layer anti-cracking method
The invention discloses a large-volume concrete body surface layer anti-cracking method which comprises the following steps: step 1, layering an anchor block, and starting to construct the anchor block from the lowermost layer; 2, a stiff framework is arranged at the position of the surface of the anchor block body on the layer, after a supporting steel bar net piece is installed on the stiff framework, a dense net is fixed to the supporting steel bar net piece, and an anti-cracking steel bar net piece is installed on the stiff framework; 3, synchronous pouring is conducted on the anchor block body and the anti-cracking concrete layer of the layer; and 4, the step 2 and the step 3 are cycled on the poured anchor blocks, and construction of the next layer of anchor blocks is conducted till construction of the anchor blocks is completed. According to the anchor block, the anti-cracking concrete layer is arranged on the surface of the anchor block, the stiff framework and the supporting steel bar mesh are connected with the anti-cracking steel bar mesh and the sealing mesh, so that the overall strength and overall stress of the anchor block are improved, the stress performance of the anchor block is improved, and cracking of the anchor block is reduced.
本申请公开一种大体积砼体表层抗裂方法，包括：步骤1、对锚块进行分层，从最下方的一层开始对锚块进行施工；步骤2、在该层的锚块本体表面的位置设置劲性骨架，将支撑钢筋网片安装在劲性骨架上后，再将密布网固定在支撑钢筋网片上，在劲性骨架上安装防裂钢筋网片；步骤3、对该层的锚块本体和防裂混凝土层进行同步浇筑；步骤4、在完成浇筑的锚块上循环步骤2和步骤3，进行下一层锚块的施工，直至完成锚块施工。本申请通过在锚块表面设置防裂混凝土层，并采用劲性骨架、支撑钢筋网片和防裂钢筋网片、密闭网相互连接来提升锚块整体强度，整体受力，改善了锚块的受力性能，减少锚块的开裂。
