Combined type pile hammers for fishing hammers and hammer fishing method

Abstract

The invention relates to combined type pile hammers for fishing hammers. The combined type pile hammers for fishing the hammers comprises A-type pile hammers, B-type pile hammers and C-type pile hammers. The three types of pile hammers comprise cylindrical hammer bodies and conical pile tips. The pile tips are fixedly installed at the lower ends of the hammer bodies. According to the connection mode, parts of the two pile hammers are embedded into the other parts of the pile hammers, bolts are embedded into the bolt holes formed in advance after embedding, and then nut screwing is carried out,so that the two pile hammers are fixedly connected. During hammer fishing, the number of the A-type pile hammers is selected according to the size of the constructed pile diameter, and the three types of pile hammers are assembled to finally form the combined type pile hammers with different sizes, such as BAC, BAAC and BAAAC, and the combined type pile hammers can be used for hammer fishing construction with different pile diameters. According to the combined type pile hammers for fishing the hammers, slender and small pile hammers are combined together to form the combined type pile hammerswith a variable size, the design is novel and ingenious, the combined type pile hammers can be drilled to the position of hammer burying at one time during the hammer burying treatment, and the problems of slow speed, time consumption and low efficiency when a pile hammer with a smaller diameter is used for multiple drilling in a traditional method are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a combined pile hammer and a method for fishing the hammer. Background technique [0002] In the process of pile foundation construction, buried hammer accidents often occur due to poor mud wall protection effect in pile holes or hole wall collapse caused by karst caves, quicksand layer encountered in geological layers, stuck hammer not lifted in time, etc. The traditional buried hammer treatment method is to use a slender hammer to repeatedly impact to the buried hammer position, and then pull out the buried hammer through a hoist. This construction method has the disadvantages of low efficiency and slow construction process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combined type pile hammer and a method for picking up the hammer for the low efficiency and slow speed of the hammer picking proce...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a combined type pile hammer and a method for picking up the hammer for the low efficiency and slow speed of the hammer picking process in the above-mentioned prior art. This combined pile hammer can be used once It can effectively solve the problems of slow speed and low efficiency of traditional construction methods, and can adjust the combination of pile hammers according to the actual pile diameter.
