The invention relates to the technical field of foundation pit construction, in particular to earthwork foundation pit tamping equipment which comprises a jolt ramming disc, an inserting sleeve is fixedly connected to the middle of the upper surface of the jolt ramming disc, a drill rod used for being installed in an excavator breaking hammer is inserted into the inserting sleeve, and two limiting pins are symmetrically installed on the outer surface of the lower end of the drill rod; two vertically-arranged long round openings are symmetrically formed in the outer surface of the inserting sleeve, a base plate is fixedly connected to the lower end of the jolt ramming disc, a plurality of vertical holes are evenly formed in the upper surface of the base plate, blind holes with the same number as the vertical holes are evenly formed in the upper surface of the base plate, and the blind holes communicate with the vertical holes through strip-shaped grooves. A circular groove is formed in the upper portion of the base, a disc is arranged in the circular groove, a plurality of column rods used for blocking the vertical holes are evenly installed on the lower surface of the disc, and the disc is connected with the vibration compaction disc through a connecting piece, and the vibration compaction disc has the following beneficial effect that negative pressure resistance formed between the vibration compaction disc and earthwork with large humidity in a foundation pit is reduced.
本发明涉及基坑施工技术领域，具体的说是一种土石方基坑填实设备，包括振实盘，所述振实盘上表面中部位置连接固定有插接套，所述插接套内安插有用于安装在挖机破碎锤内的钎杆，所述钎杆下端外表面对称安装有两个限位销，所述插接套外表面对称开设有两个竖向布置的长圆口，所述振实盘下端连接固定有底盘，所述底盘上表面均匀开设有多个竖孔，所述底盘上表面均匀开设有与竖孔数量相同的盲孔，所述盲孔与竖孔之间通过条形槽相连通，所述圆槽内设有圆盘，所述圆盘下表面均匀安装有多个用于封堵竖孔的柱杆，所述圆盘通过连接件与振实盘相连接，本发明具有如下有益效果：减小振实盘与基坑内湿度较大的土石方之间形成负压阻力。
