Abstract
The present invention discloses construction method of extending the end foundation in original workshop. The method includes: the first constructing the foundation piles for the end corner column on the bedrock or other bearing layer meeting the design requirement and to reach the level of foundation pile top; then roughing and cleaning the surface of original corner column in the extension joint of the extending end; constructing new corner column foundation on and around the available foundation column through depositing in required building modulus position; and final depositing new column on the new corner column foundation. The present invention has no influence on original workshop structure, and has less engineering investment, short construction period and other advantages.
Description
Technical field:
The present invention relates to a kind of building engineering construction method, particularly relate to the job practices on basis, a kind of new and old buildings thing junction surface.
Technical background:
Original old industrial production factory, the scale of production department only can satisfy the needs of production capacity at that time; Along with the development of producing, because the improvement of production technology, the raising of production capacity or the renewal of production equipment etc., original production department scale can not satisfy the existing needs of producing.Thereby, must carry out reorganization and expansion to original factory building.When extension was pile foundation, way in the past was: insert a non-standard segment (often being 2500mm or 3000mm) in original, enlarging junction, the later post distance of non-bid section still is standard module (being generally 6000mm).Can reduce the influence of the enlargement of the factory buildings like this to original factory building, but a series of nonstandard components such as footing beam, crane girder, roof panel have been increased in non-standard segment, this way not only can not be avoided the influence to original structure fully, and has prolonged the duration of a project, has increased construction investment.
Summary of the invention:
The objective of the invention is to: a kind of new existing one-storied factory continuation end foundation construction method is provided, and this method does not influence former mill construction, can save construction investment, shortens the duration of a project.
The present invention is achieved in that at first, the foundation pile (1) on construction enlarging end corner post basis, make foundation pile (1) place basement rock or the bearing stratum that meets design requirement on, the end face of foundation pile (1) reaches design elevation; Secondly, will extend the end shrinkage joint locate the surperficial hacking of original corner column foundation (2), clean with water clean; Then, construction enlarging new corner column foundation (4) makes new corner column foundation (4) place foundation pile under construction (1) to go up and parcel original corner column foundation (2), builds by the position that meets construction module; At last, on new corner column foundation (4), build or install new corner post (3).
During cast, the position of shrinkage joint axis is 500mm apart from the center of original corner column foundation (2), and the center of the new corner post (3) of distance is 600mm.
In general, original old factory building all has 10 years even longer service life, its patten foundation settlement, distortion all tend towards stability, bearing capacity of soil, density all are improved largely between ground and basis, thereby coordinate substantially with the foundation deformation on original factory building corner post basis on the corner post basis in the stake of enlarging end group, can not occur because of the uneven damage of foundation settlement, and avoid the making of nonstandard component and the influence of original factory building to structure.
The invention has the beneficial effects as follows: do not influence former mill construction, have the saving construction investment, shorten advantages such as duration of a project.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment:
Embodiments of the invention: a certain existing one-storied factory is extended, and this single-storey factory building is built by building standard modulus construction, i.e. 6000mm standard column distance, and end span and place, shrinkage joint are 5500mm, do not consider that the enlarging of factory building prolongs.
Existing one-storied factory continuation end foundation construction method is as follows: at first, the foundation pile 1 on construction enlarging end corner post basis, make foundation pile 1 place basement rock or the bearing stratum that meets design requirement on, the end face of foundation pile 1 reaches design elevation, as shown in Figure 1; Secondly, with the surperficial hacking of place, enlarging end shrinkage joint original corner column foundation 2, clean with water clean; Then, enlarging new corner column foundation 4, make new corner column foundation 4 place on the foundation pile under construction 1 and parcel original corner column foundation 2, build by the position that meets construction module, the position that makes the shrinkage joint axis is 500mm apart from the center of original corner column foundation 2, the center of the new corner post 3 of distance is 600mm, as shown in Figure 2; At last, on new corner column foundation 4, build or install new corner post 3.
Claims (2)
1. existing one-storied factory continuation end foundation construction method is characterized in that: at first, the foundation pile (1) on construction enlarging end corner post basis, make foundation pile (1) place basement rock or the bearing stratum that meets design requirement on, the end face of foundation pile (1) reaches design elevation; Secondly, will extend the end shrinkage joint locate the surperficial hacking of original corner column foundation (2), clean with water clean; Then, construction enlarging new corner column foundation (4) makes new corner column foundation (4) place foundation pile under construction (1) to go up and parcel original corner column foundation (2), builds by the position that meets construction module; At last, on new corner column foundation (4), build or install new corner post (3).
2. existing one-storied factory continuation end foundation construction method according to claim 1 is characterized in that: the position of shrinkage joint axis is 500mm apart from the center of original corner column foundation (2), and the center of the new corner post (3) of distance is 600mm.
