Abstract
The utility model provides a prefabricated bulkhead for hand excavated pile. One prefabricated bulkhead for hand excavated pile is composed of a plurality of arched plates. The utility model is characterized in that the arc surface of each arched plate is provided with a small hole, the both sides are provided with convex connecting columns, the column surface is provided with a groove, and a hollow pile with holes is arranged in the arched plate. The utility model can enhance or decrease the friction force according to the different geological conditions. The prefabricated bulkhead for hand excavated pile can rapidly diminish and discharge water to guarantee the construction progress and the construction quality. The utility model can carry out the serial construction in the stratum with poor environment condition and complicated condition, such as soft soil, shoal, lake, river, and marsh. The problem that the hand excavated pile can not carry out the downward excavation in the stratum with thicker or thick sludge, running sand, and full water can be fundamentally solved.
Description
The utility model relates to a kind of prefabricated bulkhead, the prefabricated bulkhead that especially a kind of new method hand excavated pile is used.
The normal hand excavated pile that adopts in the construction work foundation construction when borehole, is the hole of avoiding the hole wall landslide from top to bottom to dig out certain altitude earlier, again along hole wall formwork erection concrete perfusion as retaining wall.But this method can only be used in the place that geological condition is better, hole depth is little.In complicated geology, place that hole depth is big, in especially thicker mud, the water saturation flowing sand layer, be easy to generate stream mud, quicksand and can't dig down.Near but also the safety of building jeopardizing because of sinking of ground all around near the borehole and position, hole easily.Chinese patent discloses the light prefabricated retaining wall of a kind of hole digging pile for No. 94226917.9, it is made up of 2-8 piece arcuation cement pre-fabricated panel, a piece is assembled into retaining wall with it during construction, but its unreasonable structure, use single, limitation more can not be used for the big dark pile driving construction of mud, quicksand and hole depth and side pressure.So although existing hand excavated pile has lot of advantages, owing to have above-mentioned these weak points, so limited its further promotion and application.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of many types of formula and can precipitation is provided, and also can improve the positive frictional force of stake or reduce the new method hand excavated pile prefabricated bulkhead of the negative skin friction of pile of stake according to geological condition.
Scheme of the present utility model is: it is made of the polylith arc, it is characterized in that the cambered surface of each arc plate is provided with aperture, and both sides are provided with the joint pin of projection, and cylinder is provided with groove, as mud jacking and sealing.The joint pin of wherein said projection is the joint pin to outer lug, perhaps inwardly protruded joint pin; Groove on the cylinder is at least one, and is located on the cylinder of the outside or on the inboard cylinder, also is provided with the hole on the cylinder, is used for being connected with its piece arc; Cambered surface is vertical cambered surface, becomes cylinder barrel after the assembling, when the geology structure is weak soil or quicksand, be coated with lubriation material at the cylinder barrel external surface, to reduce the negative skin friction of pile, makes the not downslide displacement with the consolidation settlement of weak soil or quicksand on every side of retaining wall, guarantees workmanship; Outer down oblique cambered surface in addition cambered surface can be becomes up-small and down-big drum after the assembling, when the geology structure is hardpan, and mud jacking behind top placing of concrete that can be retaining wall outside or the pile, in case raising frictional force, the assurance construction quality; Hole on the cambered surface is a hole pattern, so that as the quick precipitation of precipitation well time spent energy, is about to the outer water of retaining wall and filters in the back inflow retaining wall by aperture, with its extraction, improve construction quality, guarantee construction speed, mix glass fabric and loaded filter, then effect is more obvious.
A scheme more of the present utility model is: it is made of the polylith arc, the cambered surface that it is characterized in that each arc plate is provided with aperture, both sides are provided with the joint pin of projection, and cylinder is provided with groove, in arc, be provided with hollow pile with holes, this hollow pile is prefabricated component or on-the-spot pouring part, can draining precipitation, can keep off native antiskid again.
The utility model compared with prior art has following advantage and effect: owing to be provided with the joint pin of projection on retaining wall, be mainly used in the top power post of jack, and be convenient to install execute in, can carry out sealing and mud jacking by the hole that two cylinder grooves form, thereby can be according to different geologic structures, improve or reduce frictional force, guarantee construction speed and construction quality; In addition owing to be provided with precipitation draining hole pattern on retaining wall, the quick precipitation draining of decapacitation guarantees outside construction speed, the construction quality, can construction continuously in the stratum of geological conditions such as weak soil, shoal, lake, river, marsh and construction environment difference.Fundamentally solve the difficult problem that hand excavated pile can't dig down in stratum such as thicker or very thick mud, water saturation flowing sand and shallow water, marsh and environment, be the novel construction method of hand excavated pile.

The specific embodiment that provides below in conjunction with accompanying drawing is described further the utility model, is not limited only to this but hold within the utility model.
Among Fig. 1,1 is hole pattern, is located on the arc of retaining wall, and 2 is joint pin, be located at the both sides of arc, and inwardly protruding, 3 is groove, be located at the lateral surface of post, be used for mud jacking, 4 is groove, be located at the lateral surface of post, be used for hermetic seal, 5 is screw, be located on the lateral column, be used for being connected with its piece arc, 6 is sealed tube, be located at the end face of arc, 7 is arc, is vertical arc.
Among Fig. 2,2 is joint pin, to outer lug, and is located at the both sides of arc, and 8 is the arc wooden partition, is inclination arc outer down in last, and all the other are identical with Fig. 1.
Among Fig. 5,9 is hollow pile, and 10 is aperture, is located on the pile lining.
