Auxiliary device for filling pipe with sand

Abstract

The invention discloses an auxiliary device for filling a pipe with sand, and relates to the technical field of pipeline filling devices. The auxiliary device comprises a power assembly, movable supporting frames, a lead screw and a sand filling assembly; the movable supporting frames are fixedly installed on the side face of the power assembly; the two movable supporting frames are fixedly connected through the lead screw; the sand filling assembly is in threaded transmission fit with the lead screw; a first supporting sleeve is rotatably matched with the lead screw; and a threaded hole is inthreaded transmission fit with the lead screw. The whole device is arranged at the top of a pre-buried channel; a third motor is started to drive a stirring rod to stir gravel, a fourth motor is started to drive crushing blades to stir and crush the gravel, the gravel with the qualified diameter falls into the pre-buried channel through filtering holes, a hydraulic cylinder is started to drive pressing plates to tamp a filling layer, and a second motor is started to drive the lead screw to rotate, so that the sand filling assembly moves back and forth along the pre-buried channel; and fillingand tamping of a pre-buried pipeline are achieved.

Description

technical field [0001] The invention belongs to the technical field of pipe filling devices, in particular to an auxiliary device for filling sand into pipes. Background technique [0002] Pipeline filling is an important process of burying communication cables, water pipes, gas pipes and other easily damaged pipes underground and filling them with sand and gravel to protect the pipes from damage. For pipeline filling at the construction site, a pre-embedded channel is usually excavated on the ground, and the pre-embedded channel is leveled, and the pre-embedded pipeline is placed inside the pre-embedded channel, and sand, soil blocks, etc. are manually filled. Fill in the pre-buried channel and tamp it manually or with a tamping machine. [0003] However, the sand, clods and other fillers used to fill the pipes have not been screened by particle diameter, and are directly filled into the pre-buried channel to cover the pre-buried pipe. Due to the existence of large particl...

Problems solved by technology

[0003] However, the sand, clods and other fillers used to fill the pipes have not been screened by particle diameter, and are directly filled into the pre-buried channel to cover the pre-buried pipe. Due to the existence of large particle groups between the sand layer and the soil layer, As a result, there are gap layers with a very high density in the filling layer, which increases the difficulty of compaction in the later stage, and it is difficult to achieve the tightness of the filling layer, which greatly reduces the protection effect of the embedded pipeline; manual filling and compaction operations are time-consuming and labor-intensive And reduce the efficiency of pipe filling
