Problems solved by technology

[0004] In the existing grounding foundation, the grounding device is installed in the hole-digging pile, but the existing project needs to pour a large amount of concrete and install a large number of steel bars while ensuring the stability of the grounding foundation. Large amount, the existing grounding resistance is high, the lightning protection effect is average, and it cannot withstand the lightning strike of ultra-high voltage

Embodiment 2

[0027]Embodiment 2 A kind of installation equipment for lateral tree root digging piles, including a positioning seat b1 and a piling device b2, the positioning seat b1 is in the shape of a ring, and the positioning seat b1 is provided with an installation angle parallel to the tree root pile a2 The positioning groove b3, the piling device b2 includes a mounting seat b4, a guide cylinder b5, an impact member b6, and a first driving device b7 that drives the impact member b6 to move up and down in the guide cylinder b5, and the installation seat b4 is fixed on the ground Above, the guide cylinder b5 is installed on the installation seat b4 and extends into the ground pile foundation a1, and the outer wall of the guide cylinder b5 is provided with several sets of piling units, and several sets of piling units are equally spaced along the axial direction of the guide cylinder b5 , the piling unit includes a piling head b8 aligned with the tree root pile, the piling head b8 is slid...

specific Embodiment approach

[0031] As an improved specific implementation, the first mounting plate b11 and the second mounting plate b12 are provided with an annular mounting groove b17, and the adjustment seat b10 includes several disc-shaped positioning flaps b18, the The installation groove b17 is used to clamp the positioning flap b18, and the installation groove b17 restricts the up and down movement of the positioning flap b18, so as to prevent the reaction force of the impact member b6 on the guide cylinder b5 from causing the guide cylinder b5 to move in reverse. The preferred positioning flap b18 and piling head b8 Set at intervals in the horizontal direction.

[0032] As an improved specific implementation, the end of the impact part b6 and the piling head b8 that conflict with each other is tapered. When the piling head b8 and the conical surface of the impact part b6 contact each other, when the piling head b8 goes down, the impact part b6 pushes The piling head b8 performs piling on the roo...

Abstract

The invention relates to a lateral tree root hole digging pile and installation equipment thereof. A plurality of tree root piles are driven into a ground pile foundation along a hole wall to form alateral tree root hole digging pile composite grounding foundation, and the tree root piles and the ground pile foundation are poured into an integral foundation. The lateral tree root piles can actively bear vertical and horizontal loads, the buried depth and pore size of an intermediate concrete foundation are effectively reduced, the stress state is improved, the engineering quantity is reduced,and meanwhile, the earthwork quantity of a foundation pit and the influence on the surrounding environment are reduced; economy and environmental protection are achieved, wiring terminals are arrangedat the ends, extending into a cement shell, of the tree root piles, and grounding terminals are arranged on the parts, exposing out of the ground, of the tree root foundation; the grounding terminalsare used for connecting grounding downleads, a grounding net which enables the grounding terminals to be connected with the tree root pile terminals is arranged on the tree root foundation, the treeroot piles serve as grounding electrodes, and effective grounding resistance of a whole tower is reduced to 5 omega by combining the multiple grounding electrodes in parallel to form a unified grounding module; and meanwhile, the concrete characteristics improve the corrosion resistance and structural strength of the grounding electrodes, and the maintenance cost of a grounding device is reduced.

Description

technical field [0001] The invention relates to the field of experimental equipment, and more particularly to a lateral tree root digging pile and installation equipment thereof. Background technique [0002] Ordinary manual hole-digging piles are one of the commonly used foundation types for transmission line towers in mountainous and hilly areas. This type of foundation belongs to the undisturbed soil foundation. It does not use large excavation, but uses concrete retaining wall support, and then manually excavates to the designed buried depth. Finally, the soil model is used to form the foundation geometric size model, and the reinforcement cage is lowered and concrete is poured to form the foundation. . [0003] In power systems, connecting some part of electrical equipment to the earth is called grounding. The grounding in the power system can be divided into working grounding, lightning protection grounding and protective grounding according to different grounding pu...
