Counterweight each parts of formula steel pipe pile foundation of the present invention are all prefabricated components, namely ensure that construction quality, accelerate construction speed simultaneously, meet the requirement of whole process mechanized construction. On basic stress, concrete weight set effectively increases single pile basis and the contact surface of the soil body, adds soil lateral pressure, thus significantly increases the antidumping performance on basis. Steel pipe pile foundation top adopts reverse flange to be connected with top steel pipe bar, it is not necessary to wall screw, ensure that the smooth installation of precast concrete block. Steel pipe piling body can be considered basis arrangement of reinforcement, bear basis the overwhelming majority moment of flexure, exterior pre-cast concrete blocks can not arrangement of reinforcement or few arrangement of reinforcement, simultaneously design on also do not limit by component steel ratio, element bearing capacity relatively reinforced concrete foundation can improve more than 30%.
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the steel pipe piling body construction schematic diagram of the present embodiment;
Fig. 2 is the counterweight formula steel pipe pile foundation structural representation of the present embodiment.
Embodiment
As shown in Figure 1-2, a kind of transmitting line is from the counterweight formula steel pipe pile foundation of vertical rod, comprise steel pipe piling body 1, and it is set on steel pipe piling body 1 some precast concrete blocks 2, the bottom of described steel pipe piling body 1 is provided with a steel plate 3, described steel plate 3 is for carrying each precast concrete block 2, precast concrete block 2 on steel pipe piling body 1 is connected in series and forms weight set, the top of weight set is arranged with precast concrete cushion cap 5, the top of steel pipe piling body 1 is provided with flange 6, described flange 6 is positioned at inside steel pipe piling body 1, and flange 6 is provided with the bolt 4 installing steel pole pipe. Each precast concrete block 2 of described weight set is cylindrical, and size size uniformity causes, being provided with in the middle of precast concrete block 2 for the through hole that steel pipe piling body 1 passes, the steel plate 3 bottom described steel pipe piling body 1 is also circular, and its diameter is more than or equal to the external diameter of precast concrete block 2. Described precast concrete cushion cap 5 is square, and its length of side is greater than the diameter of precast concrete block.
