Construction device for short-distance overpass building

Abstract

The invention discloses a construction device for a short-distance overpass building. The construction device comprises a foundation plane, an electric control equipment box, an air compressor, a cement pump, a fixed column, a formed hole, a perforated pipe, a mud discharge pipe, a pressure gauge, a mud discharge port, a pressure detection head, a cement slurry discharge port, a filling reinforcing cavity, a slurry box, a slurry outlet, a main air pipeline, a suck-back water pipeline, bolt connecting holes, a mud discharge valve, a pressure sensor circuit pipe, a hole-cutting water pipeline, ahigh-pressure slurry pipeline, a standby pipeline and a suck-back air pipeline. The construction device has the beneficial effects that the pile body quality is good, cement slurry is directly adopted for spraying, the pile body quality is good after spraying is completed, the influence on the surrounding environment is small, ultra-deep construction is guaranteed, the MJS construction method regulates and controls the in-ground pressure through the in-ground pressure monitoring and forced slurry discharging means, disturbance of construction to the surrounding environment can be greatly reduced, and the ultra-deep construction effect is ensured.

Description

technical field [0001] The invention relates to a short-distance upward-spanning building construction method, in particular to a short-distance upward-spanning building construction device, which belongs to the technical field of building construction. Background technique [0002] The MJS construction technology was first used in Japan. The purpose of early development was to use it in the horizontal direction. In order to solve the problems of slurry discharge and environmental impact in the rotary spraying construction, after long-term development and application, it can be applied to inclined and vertical construction. [0003] The traditional MJS construction technology cannot realize the forced slurry discharge in the hole and the real-time monitoring of the internal pressure, and it is impossible to control the internal pressure by adjusting the slurry discharge volume, so as to achieve reasonable control of the deep mud discharge and internal pressure.
