Concrete pouring method for deep foundation pit

Abstract

The invention provides a concrete pouring method for a deep foundation pit. The concrete pouring method for the deep foundation pit is used for concrete pouring equipment, and the concrete pouring equipment comprises a conveying pipe. The concrete pouring method for the deep foundation pit comprises the following steps: installing a reinforcing die plate in a channel to be grouted, and dividing pouring areas according to the channel to be grouted and the reinforcing die plate; installing a plurality of conveying pipes at intervals in each pouring area in the circumferential direction of the reinforcing die plate; controlling the plurality of conveying pipes to sequentially pour concrete to form concrete layers; and pouring the concrete layers one by one until a grouting of the channel to be grouted is reached. According to the concrete pouring method for the deep foundation pit, the pouring areas are divided by installing the plurality of conveying pipes at intervals in each pouring area in the circumferential direction of the reinforcing die plate; and each area is equipped with one conveying pipe, overall and comprehensive pouring working is carried out on the pouring areas by virtue of the conveying pipes, and the use needs of different pouring spaces are met in the case of ensuring a pouring effect, so that continuous and cyclic concrete pouring working the circumferentialdirection of the reinforcing die plate is realized, and then the concrete pouring quality can be ensured.

Description

technical field [0001] The invention relates to the technical field of concrete pouring, in particular to a concrete pouring method for a deep foundation pit. Background technique [0002] In related technologies, there are mainly two ways of pouring concrete: [0003] 1. Concrete pouring is carried out by pumping concrete directly to the area to be poured. This pouring method is difficult for the arm of the pump truck to expand to the pouring position due to space constraints. On the other hand, the traditional vertical conveying method of high-drop concrete is likely to cause aggregate separation and concrete Waste, thereby reducing the effect of concrete pouring; [0004] 2. Use hoisting equipment to transport concrete to the area to be poured (such as a deep foundation pit). Due to the small space in the area to be poured, it is easy to cause inconvenient movement of the hoisting equipment, resulting in low efficiency in the process of conveying concrete.
