Abstract

The invention relates to the technical field of building construction, in particular to a karst cave backfilling and squeezing hammer and a squeezing device. The karst cave backfilling and squeezing hammer is characterized by comprising a squeezing hammer body (1), wherein the squeezing hammer body (1) is conical; a plurality of grooves (9) and a plurality of pressure release holes (6) are formed in the squeezing hammer body (1); the grooves (9) are formed in the upper surface of the squeezing hammer body (1) in a crossing manner; the pressure release holes (6) penetrate through the squeezing hammer body (1) and are uniformly distributed along the circumference of the squeezing hammer body (1). The karst cave backfilling and squeezing hammer provided by the invention can horizontally squeeze backfilling soil when the backfilling soil for a karst cave is stamped, so that the construction efficiency is greatly improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a karst cave backfill extrusion hammer and an extrusion device. Background technique [0002] In the prior art, after the karst cave is backfilled with the punched piles in the karst cave area of ​​the construction project, the backfilled soil is directly punched with the hammer of the original punched pile to carry out the backfilling construction of the karst cave. The specific form is as follows: when a karst cave is encountered during the construction of the punched pile, the hammer is raised. Arrange excavators to backfill plastic clay and granite blocks with a diameter of 10 to 20 cm to 0.5 to 0.8 meters above the cave surface, and then lower the punching piles and punch them with hammers. After the plastic clay and the diameter granite stones are stamped and backfilled, the above operations are continued until the cave backfilling is completed. [0003] Thi...
