Pouring forming construction process for large sewage pool supporting arm ribbed beam type wall body

Abstract

The invention relates to the technical field of building construction, in particular to a pouring forming construction process for a large sewage pool supporting arm ribbed beam type wall body. The gradient of the inner side of the inner side face of the wall body formed through pouring is 3.6%, ribbed beams are arranged on the outer side of the wall body, a plurality of triangular supporting armwalls are arranged on the outer side of the wall body, and the interval between every two adjacent triangular supporting arm walls is uniform. When the wall body is constructed, an inner side formwork, an outer side formwork and a foundation formwork need to be adopted. The inner side formwork comprises an inner wall surface formwork, an inner triangular truss, an inner side pull rod and an innerformwork back edge. The outer side formwork comprises an outer wall surface formwork, an outer triangular truss, an outer formwork back edge, a supporting arm formwork, a supporting arm back edge, a ribbed beam formwork, an outer side pull rod, an outer side connecting rod, an outer side wall plug formwork and a supporting arm cover plate. The pouring forming construction process aims to solve theproblems of existing engineering reinforced concrete wastewater pool pouring, the construction time of an engineering wastewater pool is shortened, the whole construction period is shortened and theleakage problem caused by construction joints is avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a pouring and forming construction process for a large-scale sewage pool with a rib-beam wall body. Background technique [0002] The present reinforced concrete wastewater pool is divided into two-step construction, the cushion layer is poured earlier, and the pool wall is made, installed, formworked and poured after leaving the construction joints. As a result, the wastewater pool takes too long in the entire pre-drilling construction period. At the same time, after the wastewater pool is delivered for use, it often fails to meet the design strength requirements due to insufficient maintenance periods. [0003] "Petroleum Engineering Construction" No. 05, 1990 disclosed a continuous pouring of a reinforced concrete pool, which adopts the method of continuous pouring of grout in layers, and completes all pouring of concrete from the bottom of the pool to the wall o...

AI Technical Summary

Problems solved by technology

The technology still has the following problems in practical application: the operation section is short, the vertical layering is more, the construction section of the step shape is many, the construction time of the stubble is not easy to control, the construction joints are easy to appear, and the impermeability of the pool is affected; the method In the middle "the first layer starts from the bottom of the pool, pour the inner and outer bottoms of the construction section to the design elevation and vibrate until the slurry no longer flows, and pour the second layer (that is, the wall of the pool)", the vibration time of the first layer is too long , it is easy to cause concrete segregation, cement and stone separation, sand to sink to the bottom and cement to be fully vibrated to the top, resulting in uneven and compact concrete structure, affecting structural strength and durability; steel formwork is used and no iron parts are allowed to penetrate the pool wall , the supporting steel bars in the formwork have no place to take root, it is difficult to fix, and the formwork is easy to skew

[0007] (2) This scheme is not suitable for the pouring of large sewage pools, which will make the entire construction period too long, and cannot guarantee the strength of large sewage pools;

[0008] (3) During the pouring process, the embedded parts of the steel plate will be displaced and difficult to adjust, resulting in the need for rework in the later stage, which is time-consuming and laborious, and the quality cannot be guaranteed;

[0009] (4) The wall body obtained by this pouring is complex and tall. The traditional formwork support and reinforcement are slow, labor-intensive, time-consuming, costly, and easy to expand the formwork, which will cause safety accidents and quality accidents.
