Abstract
The utility model relates to a prefabricated short pile of reinforced concrete, belonging to the building component. The upper end of a column pile body whose cross section is square has hooks, and the bottom is a four-edged cone pile tip. When used for the construction of compound pile foundation, the prefabricated short pile which can be tightly combined with soil foundations has high bearing capacity and low cost, suitable for the construction of building foundations in such complicated geological conditions as underground water, etc.
Description
Building unit is specifically related to a kind of reinforced concrete prefabricated stub.
The construction work foundation construction, the foundation pile that piling is used is the most common with precast reinforced concrete piles, generally is the flat long stake in square-section; What adopt with the tube-sinking cast-in-situ pile of prefabricated pile crown is conical precast reinforced concrete piles head, can not combine closely with the ground of carrying during construction, composite pile foundation technology (number of patent application 95110893.X) for adapting to various complicated geological environment constructions needs its corresponding reinforced concrete prefabricated stub.
The purpose of this utility model is a kind of reinforced concrete prefabricated stub that can combine closely with ground on every side that is designed for composite pile foundation.
A kind of reinforced concrete prefabricated stub of the utility model design is characterized in that the cross section is that suspension ring are arranged at the top of foursquare cylindricality pile body, and the bottom is the stake point of tetrapyamid shape, and tapering is 30 °-60 °.
Use the concrete prefabricated stub of the utility model design to carry out the composite pile foundation construction, earlier with traditional luoyang spade stake machine shoveling pore-forming, then the precast reinforced concrete piles drop shot is put in the hand-hole at the bottom of the hole, dose again through selecting the building waste or the rubble of break process, dash with the hammer ram at the bigger sharp end of the power of splitting and to ram, make and fill thing and combine more closely with soil layer around it, the reinforced concrete prefabricated stub at the sharp end is convenient to stretch into soil layer, form integral body, improved the bearing capacity of foundation pile.
The schematic diagram of a kind of reinforced concrete prefabricated stub that accompanying drawing designs for the utility model.
A kind of reinforced concrete prefabricated stub shown in the figure, pile body [1] are that the cross section is foursquare long column body, and hook [2] is arranged at its top, and the bottom is the stake point [3] of rectangular pyramid shape, and tapering is 45 °, and promptly the four sides all is an equilateral triangle.
The Prefabricated short pile of reinforced concrete that the utility model proposes, more mixed than general reinforcing bar Solidifying native prefabricated pile will be lacked, and point is easier enters in the soil layer in the stake of rectangular pyramid shape, by splitting The hammer ram of the garden cone point that power is bigger after adding building waste, rushes rammer, with ground The base layer is in conjunction with tight, and single pile bearing can reach 150KN-300KN. Use this practicality new The composite pile foundation of the Prefabricated short pile of reinforced concrete of type design can solve the Luoyang Spade punching Meet the difficult problem of water pile difficulty at the bottom of the priming concrete pile hole, also can overcome general prefabricated pile cost height Waste big shortcoming, the bearing capacity height, cost is low, is suitable for the stratum of complex geological condition Construction is its outstanding advantage.
