Abstract
The utility model discloses a hand excavated pile which is composed of a lifting device arranged on the ground, an excavating device arranged under the ground, and a protective wall. The utility model is characterized in that the excavating device is composed of an edge foot, a jack arranged on the edge foot, a protective drum arranged outside the jack, a safety shield arranged in the jack, and a flap arranged at the lower part of the edge foot. The problem that the hand excavated pile can not carry out the downward excavation in the stratum with thick or thicker sludge, running sand, full water, etc. can be fundamentally solved. The utility model can carry out the continuous operation, the construction progress is raised, and the construction quality is good without noise and pollution. The hand excavated pile is suitable to construct in the strata with complicated geological conditions, such as shoal, a lake, a river, marsh, etc. The utility model is a novel hand excavated device.
Description
The utility model relates to a kind of hole digging pile, especially a kind of new method hand excavated pile that can intercept water and drift sand and work continuously.
The normal hand excavated pile that adopts in engineering foundation construction, when borehole, for avoiding the hole wall landslide, the hole of from top to bottom digging out certain altitude earlier, again along hole wall formwork erection concrete perfusion as retaining wall.But this method can only be used in, and geological condition is better, underground water reaches the little place of hole depth less.In complicated geology, place that hole depth is big, in especially thicker mud, the water saturation flowing sand layer, then gush mud, gush sand or landslide can't be dug down because of generation.Near but also the safety of building jeopardizing because of sinking of ground all around near the borehole and position, hole easily.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 providing a kind of can work continuously in bad grounds such as weak soil, thicker mud, water saturation flowing sand, constantly the novel artificial hole digging pile that digs down.
Scheme of the present utility model is: it is characterized in that excavating gear by the sword pin by being located at ground lifting appliance and being located at underground excavating gear and prefabricated bulkhead constitutes, and places protection tube, safety guard and jack on the sword pin to constitute.Wherein the sword pin is made of at least two cylinder bodies, and each cylinder body lower end is by the face of inwall to the outer wall inclination, forms an inverted cone, and cylinder body inwall is provided with boss, and boss bottom to beveled end is provided with groove, is used for being connected with other member; Protection tube is made of at least two circular arc plates, and the periphery of each plate is provided with a plurality of fixing holes, is used for plate is connected into cylindrical drum, can't construct to prevent mud, sand etc. around the hole from entering in the hole; Safety guard is made of round platform, and the top of round platform is provided with carries native hole and steel wire guard, hurts sb.'s feelings with the weight that prevents to fall above; Jack is the Jackstay type hydraulic jack, and the one end places on the sword pin, and the other end withstands retaining wall or retaining wall support.
Another program of the present utility model is: it is characterized in that excavating gear by the sword pin, the flap valve formation that places protection tube, safety guard, the jack on the sword pin and be located at the sword underfooting.Wherein flap valve is that the arc lobe of taper seat constitutes by at least two its tops for bottom, the face of cylinder, and the upper end of each arc lobe is provided with tenon, is used for being connected with the groove of sword underfooting portion.When running into bad grounds such as weak soil, mud or water saturation flowing sand, flap valve is closed up sealing, jacking is opened the excavation pore-forming during to better stratum again, efficiently solves the difficult problem that can't construct in water, mud etc.
The utlity model has following advantage and effect: fundamentally solved 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 can work continuously, greatly improved construction speed, and construction quality is good, noiselessness, pollution-free, be suitable for constructing in the environment of complex formation such as shoal, lake, river, marsh and condition difference, real is a kind of novel manually digging hole device.
