Abstract
The present invention relates to a building construction method, particularly to a construction method that a deep foundation pit engineering pile is used for replacing a wall protective pile. The present invention comprises the following steps: constructing a deep foundation pit engineering pile in a conventional method; replacing a wall protective pile by an outer ring engineering pile, and simultaneously, eliminating an overhanging bracket at the overhanging part of a floor base plate lifting the overhanging bracket in an equal height mark position of a first floor plate at the ground, etc.; lifting the upper end of the outer ring engineering pile to enable a capping beam position of the outer ring engineering pile to carry the bracket under the overhanging bracket. Compared with the existing method, the method of the present invention saves the wall protective piles and a great amount of earth, and has obvious economic benefits.
Description
The invention belongs to a kind of foundation structure of building and job practices thereof.
To establish at present a lagging pile that encloses the temporary lining effect in the Foundation Pit Construction in the foundation ditch outer ring.Because of the building overhanging 2000mm of the body base plate bracket of encorbelmenting, generally between lagging pile and outer ring engineering piles, possess corresponding spacing.The supporting and protection structure of this kind job practices is occupied significant proportion in the Foundation Design cost.For example the foundation ditch area of plane is 100 * 70M
2, just need 340 of lagging piles, dark 8 meters of foundation ditch, then the earth volume between external and lagging pile approximately is 5440M in the building
3Therefore, if can cancel lagging pile, saving the earth volume between body of wall and lagging pile, is an important economy measure of foundation construction.
The objective of the invention is to propose a kind of lagging pile that utilizes the permanent structure engineering piles to replace temporary lining, save the foundation structure of building and the job practices of the earthwork simultaneously, to reach the purpose that reduces the basic engineering construction cost.
The content of foundation structure of building of the present invention is: it only comprises deep foundation ditch outer ring engineering piles, and the sponson of the building bottom of the building plate bracket position of encorbelmenting is positioned at first floor absolute altitude place, face of land place, and the cap position, upper end of above-mentioned outer ring engineering piles just is positioned at below the above-mentioned bracket of encorbelmenting so that support this bracket.The concrete construction sequence of its foundation structure of building is that outmost turns engineering piles stake top mark height is fixed on negative one deck underfloor, and reserve the space, cross section of cap, digging the first step earthwork to outer ring engineering piles again pushes up, beat engineering piles steel bar concrete cap, and then dig the earthwork of second step to the foundation ditch hypodermis, when the building body construction is extremely born one deck floor place, on cap, beat the bracket of encorbelmenting.
Its concrete construction sequence can be that outmost turns engineering piles stake top mark height is fixed on negative one deck underfloor, and reserve the space, cross section of cap, digging the first step earthwork to outer ring engineering piles again pushes up, beat engineering piles steel bar concrete cap, and then dig the earthwork of second step to the foundation ditch hypodermis, when the building body construction is extremely born one deck floor place, on cap, beat the bracket of encorbelmenting.The cap cross section is with 2000 * 400mm
2Be advisable.
The present invention changes the former bracket position of encorbelmenting of being located at bottom of the building plate place and is located at the negative one deck place of building body, simultaneously with outer ring engineering piles stake jacking height, utilizes this outer ring engineering piles to replace lagging pile, thereby reaches the purpose of invention.
Embodiments of the invention are as shown in drawings:
Fig. 1 is a prior art foundation structure of building schematic diagram.
Fig. 2 is a foundation structure of building schematic diagram of the present invention.
Number in the figure is represented:
1 engineering piles, 2 outer rings lengthenings engineering piles, 3 brackets of encorbelmenting, 4 lagging piles, 5 caps.
Accompanying drawing is specified foundation structure of building of the present invention and job practices thereof in conjunction with the embodiments:
The prior art foundation structure of building as shown in Figure 1, the overhanging about 2000 * 400mm in body base plate place, building
2The bracket 3 of encorbelmenting, there is a circle lagging pile 4 at about 500mm place outside it, needs during construction lagging pile inner ring pit earthwork is all got only to end skin.The inventive method rises to negative one deck floor place with bracket 3 positions.The outmost turns engineering piles is a lengthening engineering piles 2, and its cap 5 supports high-order bracket 3, and engineering piles 2 plays lagging pile simultaneously in construction, replaced lagging pile 4 of the prior art.Being provided with of engineering piles 1 is constant.Comparison diagram 1 and Fig. 2 foundation structure of building of the present invention as can be seen and job practices thereof have compared with prior art been saved lagging pile and a large amount of earthwork, have tangible economic benefit.
Claims (3)
1, a kind of foundation structure of building, it is characterized in that it only comprises deep foundation ditch outer ring engineering piles, and the sponson of the building bottom of the building plate bracket position of encorbelmenting is positioned at first floor absolute altitude place, face of land place, and the cap position, upper end of above-mentioned outer ring engineering piles just is positioned at below the above-mentioned bracket of encorbelmenting so that support this bracket.
2, the job practices of the described foundation structure of building of a kind of claim 1, it is characterized in that concrete construction sequence is that outmost turns engineering piles stake top mark height is fixed on negative one deck underfloor, and reserve the space, cross section of cap, digging the first step earthwork to outer ring engineering piles again pushes up, beat engineering piles steel bar concrete cap, and then dig the earthwork of second step to the foundation ditch hypodermis, when the building body construction is extremely born one deck floor place, on cap, beat the bracket of encorbelmenting.
3, foundation structure of building job practices according to claim 2 is characterized in that the cap cross section is 2000 * 400mm
