Abstract

The utility model relates to an indoor dense extruder which is composed of a pile frame, a hoisting transmission system and an impact guide pipe, and can directly and indoors carry out fast and high-quality dense extrusion and reinforcement for dilapidated house buildings, old houses added with layers and the reconstruction of engineering foundations, wherein, length of the impact guide pipe corresponds to the indoor headroom, one end of the impact guide pipe is sealed and is only provided with an open hole, a punching hole is arranged on a pile head on the other end, a punching hammer capable of moving up and down along the inner part of the pipe is arranged in the impact guide pipe, and a punching head is arranged on the punching hammer; the hoisting transmission system is provided with a clutch. The punching hammer is lifted, and the pile head is directly hammered by the dead weight of the punching hammer, so the utility model has the advantages of strong penetrating power and good perpendicularity.

Description

Indoor dense extruder

The utility model relates to a kind of building lot construction machinery, and is particularly a kind of by pile frame, the extrusion press that hoisting system and immersed tube are formed.

For the building that has built up, because the ground accident that a variety of causes causes, if the treating method that adopts demolition of buildings to rebuild certainly will cause the waste of human and material resources, financial resources.And directly carry out ground stabilization indoor, then be a kind of economy and effective way.This method can be by being carried out to hole compacted operation with immersed tube to ground by machine power indoor, producing compacted effect to ground vertical direction and horizontal direction, and in the hole pile, thereby realize high-quality, fast processing to the ground accident.Yet existing all kinds of compacted machinery but can't be used for carrying out the ground extruding of indoor ground, and reason is: one, and they all do not have the function of the office operation narrow and small in the space; Its two, be feature greater than the degree of depth of (or equaling) pore-forming all in its structure, and this does not exactly allow for indoor limited height with immersed tube length.

The purpose of this utility model provides a kind of can the processing to realize the indoor ground ground extruding that dilapidated house building, old room is added layer and alteration work at the indoor indoor extrusion press that carries out compacted operation.

The utility model is achieved in that it is by the pile frame that pulley is housed, has motor, reel, the elevator transmission system of wire rope etc. is formed with the impact conduit that has pile crown, and the length and the indoor headway of building of impacting conduit adapt, impact and to have on the pile crown of conduit one end and impact the punching that conduit cavity communicates, the other end is a blind end, only have through hole at port, can be in pipe up and down along its length block stamp is housed impacting conduit cavity, block stamp is provided with and impacts the drift that the conduit punching matches, and the wire rope of hoisting system is connected with block stamp with impact conduit blind end through hole by the pulley on the pile frame.Because block stamp is built in the restriction of impacting conduit and impacting catheter length, has effectively adapted to the requirement of office operation.When hoisting system rose to suitable height by wire rope with block stamp, block stamp will impact conduit simultaneously to be sling, and under action of gravity, impacted conduit and ground and was the nature plumbness.By control to wire rope, make the block stamp free-falling, under the acceleration of gravity effect, block stamp with constant weight then pile crown of impact conduit produces powerful impact and hammer action, make pile crown with the vertical contract underground layer of very big penetration power with speed, along with continuous contract is gone into, form circular stake hole, finally reach compacted effect.

The utility model is simple in structure, impact on the conduit without any power source, and hammering is carried out in pipe, thereby friction, noiseless, pollution-free in the operation, and easy to operate, speed of application is fast, and quality is good, compare with existing compacted machinery, its outstanding feature is that depth of pore forming is far longer than the length of immersed tube (promptly impacting conduit).

Accompanying drawing is the utility model embodiment schematic diagram

Below in conjunction with accompanying drawing the utility model is further narrated.

With reference to the accompanying drawings, in the pile frame bottom that pulley (1) is housed road wheel (2) is installed, thereby can move easily, folding fore-stock (3) can fold back (shown in dotted line) on the pile frame, it is highly reduced, so that smoothly by building the door and in the inlet chamber, its elevator transmission system has clutch (4), lifting and whereabouts in order to the control block stamp, impact conduit (5) upper end be equipped with have through hole conduit cap (6) to reach sealing process, simultaneously when difficulty in decannulation, can realize down beating, the lower end is and the conical pile crown (7) of conduit all-in-one-piece, has the punching (8) that communicates with duct cavity on the pile crown (7), by this punching, can will fall into outside the foundation soil discharge pipe of conduit, the pull of vacuum of pile crown portion in the time of also can eliminating tube pulling simultaneously, meanwhile, at block stamp (9) drift (10) that matches with punching (8) of having gone up relative set, this drift can be gone out outside the punching, guarantees the operate as normal of extrusion press effectively.

Claims

1, a kind of indoor extrusion press, by the pile frame that pulley (1) is housed, the impact conduit (5) that has the hoisting system of motor, reel, wire rope etc. and have a pile crown (7) is formed, and it is characterized in that:

(1), the length and the indoor headway of building of impact conduit (5) adapt;

(2), impact and to have on the end pile crown (7) of conduit (5) and impact the punching (8) that conduit (5) inner chamber communicates, the other end is a blind end, only has a through hole at port;

(3), being equipped with at the inner chamber that impacts conduit (5) can be along the up and down block stamp of its length direction (9) in pipe, block stamp (9) is provided with the drift (10) that matches with punching (8).

2, according to the described indoor extrusion press of claim 1, it is characterized in that having on the pile frame folding fore-stock (3).
