Problems solved by technology

[0003] However, if it is necessary to carry out basement foundation exterior wall construction in a restricted area, using the above existing methods, there is not enough space for personnel to operate and carry out the external formwork support of the wall, and if it is forced to carry out as large as possible Excavation of deep pits will have a serious impact on surrounding building structures

Embodiment Construction

[0022] 1. Construction steps:

[0023] 1. Draw the outer line of the basement foundation outer wall on the construction ground, and carry out the construction of enclosure piles immediately outside the outer line. In the construction process, a dense enclosure pile construction method can be used, and the distance between adjacent enclosure piles is equal to the diameter of the enclosure pile.

[0024] 2. Carry out foundation pit excavation on the elevation of the surrounding pile group composed of each surrounding piles, and then make an integral crown beam with concrete on the upper end of the surrounding pile group to connect the surrounding pile group as a whole to improve its strength .

[0025] 3. Carry out surface leveling treatment on the facade of the retaining pile group, the method is: after removing the dust, dirt, alkali film and other attachments on the side of the supporting pile, use cement mortar mixed with 10% cement quality 107 glue to mix well Carry out shotcret...

Abstract

The invention relates to the technical field of building construction, in particular to an integrated construction method for a board wall formwork and a support formwork in a restricted area. A support pile is used as a shear wall outer mold, basement foundation outer wall steel bars are bound after waterproof treatment of the vertical faces of a fender post group, and then pull screws are connected between an inner side formwork and waterproof bolts; and then a basement foundation outer wall is subjected to concrete pouring. Operation is simple and rapid, the construction time of a formwork reinforcing system and construction engineering time are shortened, diversification of reinforcing of building formworks is promoted, efficiency is improved, the construction period is shortened, and the quality and performance of buildings are ensured.

Description

Technical field [0001] The invention relates to the technical field of building construction, in particular to the construction technical method of the outer wall of the basement foundation. Background technique [0002] In the construction of the basement foundation external wall, the existing construction method is: first excavate a designed deep pit inside and outside the precast external wall, tie the steel bars at the position of the wall where the precast is needed, and place the precast wall Formwork is supported on both sides of the thickness of the body, and then concrete pouring and maintenance of the wall are carried out, and finally the formwork on both sides of the wall is removed. [0003] However, if the basement foundation external wall construction is required in a restricted area, the above existing methods are adopted, but there is not enough space for personnel to operate the external formwork support of the wall, and if it is reluctant to carry out as large as ...
