Abstract
The invention discloses a support pillar construction and erection method. The method comprises the following steps of: (a) preparing a support structure which comprises a support pillar; respectively welding a top end plate and a bottom end plate at the top end and the bottom end of the support pillar; welding an upper stiffening plate on the support pillar positioned on the lower side of the top end plate; and welding a lower stiffening plate and a water-stop ring on the support pillar positioned on the upper side of the bottom end plate in turn; (b) pushing the pillar foot of the support pillar to the position at the top of an engineering pile; and righting and straightening the support pillar; and (c) connecting the bottom end plate of the support pillar with the engineering pile in a welding way so that the engineering pile extends into an anchor rod of a plummer to connect the support pillar in a welding way; and inserting a steel wedge is inserted between the top end plate of the support pillar and the bottom of a horizontal support beam back to back. The method has the advantages of convenient operation, low cost, high strength and high applicability; and crackles appearing at an included angle of the support beam of a triangular support system at the corner of a foundation pit can be avoided effectively.
Description
Technical field
The present invention relates to a kind of construction and installation method, relate in particular to a kind of support pillar construction and erection method.
Background technology
When building foundation pit is constructed, for guaranteeing construction safety, prevent that the landslide accident from taking place, must take supporting measure to the building foundation pit of excavation.The building foundation pit supporting design and construction should be taken all factors into consideration engineering geology and hydrogeological conditions, foundation ditch type, the excavation of foundation pit pick degree of depth, falls drainage condition, surrounding enviroment are to the requirement of foundation pit side-wall displacement, factors such as all side loads of foundation ditch, construction seasons, supporting and protection structure useful life are accomplished appropriate design, well construction, economic security.
In recent years, the rapid rise of highrise building had promoted the development of deep foundation pit support technology.Various places are accumulating abundant design and construction experience aspect deep pit digging and the support technology, new technology, new construction, new technology continue to bring out.But present urban architecture spacing is very little, and the foundation ditch edge that has brings very big difficulty far from only tens meters even several meters of existed buildings to basic engineering construction, brings very big threat to surrounding environment, has also correspondingly increased construction period and operating expenses.Foundation ditch corner gusseted system brace summer is prone to crack phenomenon in pattern foundation pit supporting structure, still finds no the method that effectively addresses this problem at present.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of easy to operate, cost is low, intensity is high, applicability is strong, can effectively solve a kind of support pillar construction and erection method that crackle appears in foundation ditch corner gusseted system brace summer angle.
A kind of support pillar construction and erection method of the present invention, it may further comprise the steps:
(a) preparation braced structures, described braced structures comprises support column, top, bottom at described support column are welded top end plate, bottom end plate respectively, on the support column that is positioned at described top end plate downside, weld stiffener, stiffener and seal ring under welding successively on the support column that is positioned at described bottom end plate upside;
(b) suspension column of support column is shifted onto engineering piles tip position and support column set upright alignment;
(c) described support column bottom end plate and engineering piles are welded to connect, and dowel and support column that engineering piles stretches in the cushion cap are welded to connect; Between at the bottom of support column top end plate and the horizontal shore, insert the gad back of the body tightly at last.
Adopt the beneficial effect of the inventive method to be: easy to operate, cost is low, intensity is high, applicability is strong, can effectively solve foundation ditch corner gusseted system brace summer angle and crackle occur.
Description of drawings
Fig. 1 is the structural representation of the braced structures that adopts of the present invention;
Fig. 2 (a) and (b), (c), (d), (e) adopt the present invention's braced structures shown in Figure 1 to carry out the process schematic diagram of the method for construction and installation.
The specific embodiment
Below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described further:
A kind of support pillar construction and erection method of the present invention, it may further comprise the steps: (a) prepare braced structures as shown in Figure 1, described braced structures comprises support column 1, weld top end plate 2-1, bottom end plate 2-2 respectively in top, the bottom of described support column, on the support column that is positioned at described top end plate downside, weld stiffener 3-1, stiffener 3-2 and seal ring 7 under welding successively on the support column that is positioned at described bottom end plate upside; (b) suspension column of support column is shifted onto engineering piles 4 tip positions and support column set upright alignment; (c) described support column bottom end plate and engineering piles 4 are welded to connect, and the dowel 6 that engineering piles stretches in the cushion cap 5 is welded to connect with support column; Insert the gad back of the body tightly at support column top end plate and horizontal shore at last at 8 the end.Described support column 1 can be steel pipe.
Shown in Fig. 2 (a)-(e), described step (b) can comprise step: (1) is set up tripod 9 and tripod is placed on a side of horizontal shore to be supported, and carries out the colligation of post suspension centre and safe stay cord 12 is fixing on support column; (2) with jack 10 described support column is slowly sling by the post suspension centre; (3) shift the suspension column of support column onto the engineering piles tip position; (4) all directions safety stay cord on the support column is fixed, and added bridging 11 support column shoveing jail; (5) opposite side that tripod is moved to described horizontal shore carries out described step (c) then so that support column is set upright alignment.Safe stay cord in the described step (4) can be tied up on around the engineering piles.
(a) preparation braced structures, described braced structures comprises support column 1, weld top end plate 2-1, bottom end plate 2-2 respectively in top, the bottom of described support column, on the support column that is positioned at described top end plate downside, weld stiffener 3-1, stiffener 3-2 and seal ring 7 under welding successively on the support column that is positioned at described bottom end plate upside; (b) set up tripod and tripod is placed on a side of horizontal shore to be supported, on support column, carry out the colligation of post suspension centre and safe stay cord is fixed; (c) with jack described support column is slowly sling by the post suspension centre; (d) shift the suspension column of support column onto the engineering piles tip position; (e) all directions safety stay cord on the support column is fixed, and added bridging support column shoveing jail; (f) tripod is moved to the opposite side of described horizontal shore so that support column is set upright alignment; (g) described support column bottom end plate and engineering piles 4 are welded to connect, and the dowel 6 that engineering piles stretches in the cushion cap 5 is welded to connect with support column; Insert the gad back of the body tightly at support column top end plate and horizontal shore at last at 8 the end.
Adopt this method effectively to solve the problem that crackle appears in foundation ditch corner gusseted system horizontal shore angle after tested, set in advance this Horizontal Branch dagger, can guarantee that the crack does not appear in brace summer.
