Abstract

The invention discloses a deep foundation pit concrete pumping system, which comprises a concrete pump, a high-pressure pump pipe and a supporting frame. The supporting frame is arranged on the side wall of a deep foundation pit and is in rigidity connection with transverse supporting steel pipes, and the transverse supporting steel pipes are in rigidity connection with oblique steel pipes. The upper end of the supporting frame is fixedly connected with one end of each transverse fixing rod, the other end of each transverse fixing rod extends to the ground outside the deep foundation pit and is fixedly connected with upper supporting steel pipes, and the lower end of the supporting frame are fixedly connected with lower supporting steel pipes. Steel wire ropes are connected between the supporting frame and the upper supporting steel pipes and are in multi-point connection with the supporting frame, and upper ends of the steel wire ropes are fixed to the upper supporting steel pipes. The supporting frame is connected with the deep foundation pit by combination of rigidity connection and flexible connection, firmness in connection between the supporting frame and the deep foundationpit is guaranteed, and the supporting frame is still high in stability and rigidity when the concrete pump generates vibrating load, so that construction safety is guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to foundation pits with different depths and underground concrete pumping systems and construction methods. Background technique [0002] At present, there are more and more concrete projects in deep foundation pits, especially in the pumping of concrete in deep foundation pits, often because the concrete pumping will generate vibration loads, the frame connectors are loose, the supporting frame body is high, and the frame body cannot Connected with slope protection piles and steel waist beams, the supporting frame cannot form a flexible connection system, which can easily cause the overall frame to be unstable and the pump pipe to be blocked, leaving a large safety hazard. Contents of the invention [0003] The purpose of the present invention is to provide a deep foundation pit concrete pumping system and its construction method to solve the problem that the concrete pumping...
