Abstract
The invention discloses a method for treating foundation in a mountain area. In local oil region of a foundation ditch of a foundation in the mountain area, steel pipes are used for piping to the bedrock. Steel pipe pile block serves as a reinforced concrete bearing platform, parallels and levels to rock surface of the foundation ditch. The invention has the advantages of easy operation, greatly reducing work hours, low construction cost, good quality and the like. In the method, a construction site scaffold steel pipe is directly used for construction without needing additional purchasing; and the weight of the steel pipe per meter is only 3kg and the cost is low, thus being particularly suitable for foundation implementation of the mountain area.
Description
Technical field:
The present invention relates to a kind of mountain area Measures for Making Ground and Foundation method.
Background technology:
In the building engineering construction in mountain area, favourable one side is the building foundation can be placed on the firm rock foundation, and disadvantageously, the basement rock surface gradient is bigger owing to crouch under the mountain area, so that excavation pit, foundation trench be during to design elevation, and often rock is seen and the part is a soil by big portion on the plane, and present way is that the requirement construction is down deep-cut till seeing basement rock at the Tu Qu of foundation ditch, the soil in Jiang Tu district digs only, fills out concrete placing or the extremely basic end of rubble concrete absolute altitude from basement rock then.And local native sector width or diameter 500mm～600mm only not only can not cut the earth with machinery, and people's operation of also can't going down can only be adopted artificial " luoyang spade " to draw and dig, scratches only, and efficient is very low, and the dark more work efficiency of soil is low more, has a strong impact on programming.
Summary of the invention:
The technical problem to be solved in the present invention is: provide a kind of mountain area Measures for Making Ground and Foundation method, at the local Tu Qu of the foundation ditch basement rock of driving piles, to replace soil is drawn the traditional method of clean back concrete placing.
The local Tu Qu that the present invention is achieved in that at mountain area ground foundation ditch does the steel concrete cushion cap with the steel pipe basement rock of driving piles, steel pipe pile top, and is concordant with the rock face of foundation ditch.
The diameter of steel pipe pile is 50mm.
The end that buries of steel pipe is processed into flat-shaped, sealing.
Spacing between the steel pipe pile is 200mm.
The verticality allowable variation that steel pipe pile is inserted down is 1%.
The present invention compared with prior art has easy and simple to handlely, can significantly reduce man-hour, advantage such as construction cost is low, quality is good.It can directly adopt the building site scaffolding steel pipe to construct, need not to purchase in addition, and every meter weight of this steel pipe 3Kg, expense is cheap, is particularly suitable for the mountain area ground and implements.
The specific embodiment:
Embodiments of the invention: determine to adopt 1～3 steel pipe pile and cushion cap as calculated, direct recruitment ground scaffold steel, the pipe diameter is 50mm, and the end that buries of steel pipe is processed into flat-shaped, sealing, and the spacing between the steel pipe pile is 200mm.The personnel selection hammer impacts basement rock, and the steel concrete cushion cap is done on the steel pipe pile top, and is concordant with the rock face of foundation ditch.The verticality allowable variation of steel pipe pile is 1%, controls during hammering.
Claims (5)
