Embodiment Construction

[0017] A construction technique for large-diameter brick-concrete upside-down wells,

[0018] a. Choose the location of the working pit

[0019] The following factors should be fully considered:

[0020] ① Facilitate the construction of pipeline docking work surface and well chamber;

[0021] ②It is convenient for foundation pit excavation and earthwork transportation;

[0022] ③ It is easy to take protection and safe construction measures for above-ground and underground buildings and various pipe networks;

[0023] ④Convenient transportation;

[0024] b. Excavation of working pit

[0025] ① According to the positioning line, excavate the soil evenly and symmetrically along the lower part of the well wall, and the depth of each excavation shall not exceed 500 mm. After the surrounding circle is built, the middle part of the earth shall be excavated, and the construction shall be carried out symmetrically downward in this order. The masonry of the upper part is control...

Abstract

Construction process for a large-aperture brick and concrete reverse hanging well includes a, selecting the position of a working pit; b, excavating the working pit: firstly, uniformly and symmetrically excavating earth along the lower portion of the periphery of a well wall according to positioning lines, secondly, quickly building a well body of a dug portion of the well wall by the aid of MIO bricks and MU7.5 mortar, thirdly, adopting a reinforced concrete structure with the size of 400mmX400mm as a ring beam, fourthly, simultaneously setting a water collecting pit with the size of 500mmX600mm, fifthly, setting a concrete rear backrest according to the trend of pipelines after an established elevator is achieved, and sixthly, discharging the earth and draining water; c, draining water of the foundation pit; and d, manufacturing a working well. The strength of concrete is C20. A reverse construction method is adopted for the brick elliptical reverse hanging well according to the condition of the earth and distribution of a pipe network. Compared with the prior art, the construction method for the large-aperture brick and concrete reverse hanging well is complete, can guarantee construction quality and provides a novel standard for acceptance inspection.

Description

technical field [0001] The invention relates to a hanging well construction technology, in particular to a large-diameter brick-concrete upside-down well construction technology. Background technique [0002] The hanging well construction in the prior art is all manual excavation and bricklaying, there is no unified planning, the construction quality cannot be guaranteed, and it is difficult to check and accept. There is no complete set of construction techniques for large-diameter brick-concrete upside-down wells in the prior art. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a large-diameter brick-concrete upside-down well construction process that can ensure construction quality in view of the deficiencies of the prior art. [0004] The technical problem to be solved in the present invention is achieved through the following technical solutions, a construction technique for a large-diameter brick-concrete u...
