Problems solved by technology
[0003] Although the existing static penetration testing platform is easy to transport, at the construction site, due to the limitation of the unleveled ground, the anchoring process of the support device of the static penetration testing platform on the ground often has inconsistent anchoring angles on both sides. Either it is difficult to anchor, or it is difficult to remove after anchoring, which increases the preparation period before static penetration testing and reduces work efficiency

Embodiment Construction
[0021] see figure 1 and figure 2 , shows the static penetration testing platform support device for engineering survey claimed in the present invention, which is mainly composed of two support beams 1 and two fixed rods 2 bridged and fixed between the two. In this embodiment, the support device The improvement is mainly concentrated on the fixed rod 2, the fixed rod 2 adopts a segmented structure, and the specific structure is as follows:
[0022] The fixed rod 2 is mainly composed of two rod bodies 3 and a ball hinge box 4 fixed therebetween. The rod body 3 is detachably fixed on the support beam 1 by means of bolt connection, and the ball hinge box 4 is fixedly bridged between the two rod bodies 3 by welding. Preferably, the connection between the ball hinge box 4 and the rod body 3 can also be a detachable connection, such as flange connection, coupling connection and the like.
[0023] The structure of the rod body 3 is the same as that of the fixed rod of the common s...

The invention relates to a static sounding platform support device for engineering investigation. Thestatic sounding platform support device comprises a fixing rod. An anchoring perforation hole for allowinga fixing anchor rod to penetrateis formed in the fixing rod, an annular caulking groove havingan inferior arc-shaped cross section and coaxial with the anchoring perforation holeis formed in the holewall of the anchoring perforation hole, a complementary annular ball seat is mounted in the annular caulking groove in a relatively rotatable mode,the inner ring wall surface of the annular ball seat is exposed from the inner side of the hole wall of the anchoring perforation hole, and a hemispherical annular boss or a spiral boss whichcan be in line contact with the fixing anchor rod is arranged on the inner ring wall surfaceof the annular ball seat in a convex mode. A spherical hinge structure is mounted in the anchoring perforation holeto ensure that the spherical hinge structure canbe formed by the fixing anchor rod and the fixing rod after the fixing anchoring rod passes through the anchoring perforationso as to adapt to the anchoring angle under different terrain conditions, the fixing anchor rod can be conveniently inserted into the ground under different ground surface conditions, and thus the effect of rapid anchoring can be achieved.
Description
technical field [0001] The invention relates to the field of foundation soil in-situ testing, in particular to a static penetration testing platform support device for engineering survey. Background technique [0002] The static penetrating sounding platform is suitable for in-situ testing of civil engineering, municipal, highway and engineering foundation soil in areas of general cohesive soil, soft soil, loess and dense sandy soil. It is used to find out the change of stratum in vertical and horizontal directions, carry out mechanical stratification, determine the bearing capacity of natural foundation and estimate the bearing capacity of single pile, judge the possibility of sand liquefaction, determine the undrained shear strength of soft soil, provide soft soil Calculation index of soil foundation bearing capacity and slope stability. Existing static penetration testing platforms, such as the foldable static penetration testing platform disclosed in the prior patent 20...
