The invention relates to an anchoring and shotcreting support construction method in foundation pit construction. The anchoring and shotcreting support construction method in foundation pit construction adopts a following anchoring and shotcreting support structure in foundation pit construction. The anchoring and shotcreting support structure in foundation pit construction comprises upper supporting plates, inserting rods, inclined supporting rods, supporting mechanisms and laminated plates. The anchoring and shotcreting support construction method in foundation pit construction by adopting the anchoring and shotcreting support structure in foundation pit construction comprises the following steps that S1, a working face is excavated; S2, mortar spraying is conducted on bottom-layer concrete; S3, soil nails are placed; S4, the upper supporting plates are positioned; S5, supporting plates are placed; S6, an anchor net is laid; and S7, mortar spraying is conducted on a surface layer. Through the anchoring and shotcreting support construction method, the problems existing during existing anchoring and shotcreting support construction that the locking effect of the soil nails throughconnecting rods is poor, consequently, integrality of the soil nails is poor, the supporting effect of the anchoring and shotcreting support structure on the side wall of a foundation pit is affected,anchor net laying operation is tedious, and the anchor net is prone to folding or bending can be solved.
本发明涉及一种基坑施工中锚喷支护施工方法，该基坑施工中锚喷支护施工方法采用如下基坑施工中锚喷支护结构，该基坑施工中锚喷支护结构包括上撑板、插杆、斜支杆、支撑机构和叠合板；采用上述基坑施工中锚喷支护结构对基坑施工中锚喷支护的施工方法，包括以下步骤：S1、工作面开挖；S2、底层混凝土喷浆；S3、土钉安放；S4、上撑板定位；S5、支撑板放置；S6、锚网铺设；S7、面层喷浆。本发明可以解决现有锚喷支护在施工时存在的：连接杆对土钉的锁定效果较差，导致土钉的整体性差，从而影响锚喷支护结构对基坑侧壁的支护效果；锚网铺放操作繁琐，且锚网容易存在褶皱或者弯曲的现象等问题。
