Embodiment
[0019] further as figure 1 , figure 2 and image 3 As shown, when the alloy drill bit 12 is drilled in the drilling and pouring construction, the drill bit is equipped with an expanding head drilling tool (the expanding head drilling tool is not marked in the figure), (the diameter of the pile can be 80cm, or 1m, depending on the diameter of the pile cap at the construction site The depth of the expansion head drilling tool is generally 60cm. After the expansion head part enters the soil layer of 60cm, it can automatically break away from the drill pipe, and the expansion head drilling tool stays at the position of the 60cm deep soil layer, so that the drill pipe continues to drill to the designed pile length position, lift the concrete, lift the drill pipe to the top 60cm position, and then lift it up with the drill tool of the expansion head, and make the 1m diameter of the drill tool of the expansion head be filled with concrete together to make it reach the concrete of t...

Abstract
The invention belongs to the technical field of building construction foundation drilling tool application, and particularly discloses a novel long spiral drilling hole cast-in-situ pile top and cap integrated construction device which comprises an automatic walking vehicle, a power distribution operation room, three door head pulleys, a main rotating and winnowing machine, a support, a rock supporting rod, a horizontal head sliding member, a power transmission box, a drilling rod, a drilling rod blade, a drilling sleeve and an alloy drill bit. The power distribution operation room, the door head pulleys, the main rotating and winnowing machine and the support are arranged on the automatic walking vehicle, two ends of the rack supporting rod are connected with the support respectively, the horizontal head sliding member is arranged on the support, the power transmission box is connected with the horizontal head sliding member, the drilling rod is connected with the power transmission box, the drilling rod blade is arranged on the drilling rod, the drilling sleeve is arranged at the end of the drilling rod, a spiral connecting groove is formed inside the drilling sleeve, one end of the drilling sleeve is movably connected with the support, and the alloy drill bit is arranged at the end of the drilling rod. The problems that existing long spiral drilling machines are low in efficiency and instable in integral structure and prestress cannot reach production construction requirements are solved, the novel long spiral drilling hole cast-in-situ pipe top and cap integrated construction device is reasonable in design, meets construction standards and requirements, can integrally form pile body and pile cap concrete quickly in a high-quality manner, raw materials are saved, and production cost is lowered.
Description
technical field [0001] The invention belongs to the technical field of application of building construction foundation drilling tools, and in particular relates to a novel integrated construction device for top and cap of long helical drilled cast-in-situ piles, which can quickly and high-quality make the concrete of the pile body and the pile cap integrally formed. Background technique [0002] Long auger drilling rig, which includes two parts of hydraulic walking pile frame and drilling system. The pile frame adopts a hydraulic walking chassis with a high degree of automation. It can walk and turn 360 degrees by itself. It is equipped with four hydraulic outriggers and a walking cylinder to assist walking and turning while increasing the stability of the whole machine during construction. The whole machine can be transferred . The column is a foldable box-type column with flange connection. The column is made of two high-thickness panels and is bent by a large bending mac...
