Abstract
The invention discloses a method for embedding a deep pile survey marker, which includes the follow steps: (1) the embedding depth of a deep pile (1) is designed; (2) marker embedment is carried out; (3) the top of the deep pile (1) is embedded into a stainless steel survey marker core (2) and the upper part of the deep pile (1) is sheathed with a steel outer sleeve (3); (4) silver sand (4) is filled between the steel outer sleeve (3) and the deep pile (1) so as to separate the steel outer sleeve (3) and the deep pile (1); (5) the top of the steel outer sleeve (3) is connected with the bottom of a protection pot (5) which is sheathed outside the stainless steel survey marker core (2); and (6) a concrete reinforcing bar is installed outside the steel outer sleeve (3), and then concrete (7) is poured; and after the concrete is well maintained, a ground part of a platform outside the concrete (7) is decorated by marble (8). The method has the advantages that: silver sand is filled between an upper platform and the deep pile so as to separate the upper platform and the deep pile to ensure that the deadweight of the upper platform is not transferred to the deep pile, namely that the deep pile is in a stable state without any load. When the upper platform is bumped by an external force, the stainless steel survey marker core is not influenced, which is of significance to construction survey with high precision in industrial factories.
Description
Technical field
The present invention relates to the exploration engineering field, a kind of specifically deep pile survey mark burying method.
Background technology
The stability of measuring the control point is the prerequisite that guarantees to measure the achievement reliability, regulation and stipulation is shallow embedding (degree of depth is about the 1m) technology and the requirement at general control point at present, for the general measure control point in area is buried underground preferably for foundation condition, basic feasible solution.
But, for coastal soft foundation and the very thick area of weak soil layer, as the Baosteel in Shanghai, the Guangdong Yu Feng steel mill in Zhuhai, the Binhai New District of Tianjin, the Shoudu Iron and Steel Co of Cao Feidian etc., these coastal area weak soil layers generally very dark (the Baosteel weak soil layer in Shanghai reach more than 400 meter dark), adopt conventional shallow embedding technology stability relatively poor if measure the control point sign, the control point sign is easy to generate horizontal movement and sinking, and the accuracy and the reliability of achievement measured in influence.
Summary of the invention
The objective of the invention is to develop a kind of deep pile survey mark burying method of measuring control point stability, guaranteeing to measure the achievement reliability that improves.
Deep pile survey mark burying method of the present invention, its step is as follows:
The depth of burying of 1. dark stake 1 should be according to the design of geological mapping data, and the bottom of dark stake 1 requires to reach 2～5m in the bearing stratum of ground, with mainly build, the Pile Foundations Design degree of depth of structure is identical;
2. dark pile constructing process can be selected following method construction according to the degree of depth and foundation soil stability:
The a hand excavated pile about diameter 1.2m, is applicable to that the degree of depth buries underground less than the sign of 20m;
B diameter 400～550mm PHC stake is squeezed into, and is applicable to that the sign of the degree of depth 20～50m is buried underground;
The c bored pile, diameter 1～1.2m adopts mud off, is applicable to that the degree of depth buries underground greater than the sign of 50m;
3. dark stake 1 top embeds stainless steel and measures mark core 2, and dark stake 1 top puts steel sleeve pipe 3;
4. adopt fine sand 4 to fill between steel sleeve pipe 3 and the dark stake 1, make the two separation;
5. the top of steel sleeve pipe 3 links to each other with the bottom of protective pot 5, and protective pot 5 is enclosed within the outside that stainless steel is measured mark core 2, stainless steel is measured mark core 2 play a protective role;
6. load onto reinforcing bar 6 in the outside of steel sleeve pipe 3, fluid concrete 7 then, and after concrete curing was good, the platform face portion outside concrete seven was decorated with marble 8.
A hinged cover is arranged above the protective pot 5.
In the industrial working construction, the generally experiment stake that will squeeze into some earlier, some stake may not can be used, and at this moment can use as dark stake control point to use, and saves and buries cost underground.
The advantage of deep pile survey mark burying method of the present invention is: adopt fine sand to fill between upper brace and the dark stake, make the two separation, the deadweight of guaranteeing upper brace can not passed in the dark stake, promptly dark stake is in complete uncharge stable state, when upper brace is collided by external force, stainless steel is measured the mark core and not influenced by it, and this point has its significance in the construction survey of industrial working high accuracy.
