     In the field of buildings, a conventional building is built by a solid combination of a foundation and house columns. This kind of building structure is suitable for areas where the earth&#39;s crust is relatively stable, so that the building can stand firmly on the ground. However, if this kind of building structure is built in an area with frequent crustal motion, it will swing due to inertial crustal motion and eventually be shaken down or broken. Therefore, it is necessary to design a civil engineering anti-seismic structure.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings  1 - 4 . 
     Referring to  FIG. 1  and  FIG. 2 , a civil engineering anti-seismic structure according to a first embodiment of the present disclosure includes a base  1 , a fixing structure  2  fixedly welded at a bottom center  10   a  of the base  1 , a through-hole  6  formed on a top center  10   b  of the base  1 , a sliding groove  7  arranged on corresponding inner walls  1   b  at two sides of the base  1 , a sliding block  10  slidably connected inside the sliding groove  7  and symmetrically installed on both sides of a sliding plate  8 , a top block  3  fixedly welded at a top center  8   a  of the sliding plate  8 , a fixing groove  4  formed on a top center  3   a  of the top block  3 , a shock-absorbing damping pad  9  fixedly adhered to a bottom inner wall  1   a  of the base  1 , a first limiting plate  13  fixedly welded around the top  8   b  of the sliding plate  8 , a second limiting plate  12  fixedly welded around a top inner wall  1   c  of the base  1  around the through-hole  6 . A damping structure  11  is equidistantly welded and fixed between the first limiting plate  13  and the second limiting plate  12 . After the base  1  is fixed below the ground by the fixing structure  2 , bottom ends of house columns are inserted and fixed to the interior of the fixing groove  4 , and top ends of the house columns are fixed on house beams so that the house columns can directly squeeze the shock-absorbing damping pad  9 . In this way, a flexible connection between the base  1  and the house columns can be obtained to absorb shock waves and protect the building when the earthquake comes. When the sliding plate  8  is sliding downwardly, the damping structure  11  is stretched, under a counteracting force, the connection between the house columns and the house beams can be ensured more closely, thus ensuring the fixed stability effectively therebetween. Furthermore, both the sliding groove  7  and the sliding block  10  are provided to ensure the sliding plate  8  move stably.

When the damping structure  11  is stretched, the telescopic tube  19  is pulled out of the casing  16 , so that both the first supporting swing  17  and the second supporting spring  20  are stretched. Under a counterforce of the first supporting spring  17  and the second supporting spring  20 , the house column can move upwardly, so as to effectively ensure a tight connection between the house column and the house beam. 
     Referring to  FIG. 1 , based on the first embodiment of the present disclosure, a fifth embodiment of the present disclosure is provided that a scaling bar  5  is embedded in a side center of the top block  3  so as to conveniently and accurately check a downward depth of the top block  3 .

In this way, a flexible connection between the base  1  and the house columns can be obtained to absorb shock waves and protect the building when the earthquake comes. When the sliding plate  8  is sliding downwardly, the damping structure  11  is stretched, under a counterforce, the connection between the house columns and the house beams can be ensured more closely, thus ensuring the fixed stability effectively therebetween. Furthermore, both the sliding groove  7  and the sliding block  10  are provided to ensure the sliding plate  8  move stably. 
     The present disclosure can provide a flexible connection between the base and the house columns to absorb shock waves and protect the building when the earthquake comes, and have advantages of a novel structure, an ingenious conception and a convenient usage.
