Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building structure equipment, in particular to a building anti-floating and pressure relief structure. Background Art
[0002] In addition to normal waterproofing, the biggest safety hazard of underground buildings is uneven floating. For example, in high-water areas near rivers and lakes, or in areas with normal water levels that have experienced short-term heavy rainfall, the water level rises rapidly.
[0003] Under similar working conditions, if the construction quality of anti-floating anchor rods and anti-floating piles is not ideal, or the pile head connection parts are aged over time, or the original anti-floating design value is low, there will be hidden dangers of uneven floating of underground structures. In recent years, there have been many reports of wall cracks, beam and column cracks and even shearing caused by uneven floating of basements. The damage caused by this is generally treated by post-processing methods such as structural reinforcement, which has high processing costs and bad social impact. Even if the degree of floating is small, the uneven floating reaction force may cause cracks in the structural concrete, greatly increasing the risk of water seepage. Utility Model Content
[0004] The purpose of the utility model is to provide a building anti-floating and pressure relief structure, in which a pressure relief device is arranged to take countermeasures in advance, thereby increasing the active defense against potential floating risks in the basement and ensuring the safety of the structure, which is of great significance to the normal use of the basement.

[0008] Furthermore, a steel bar hole is provided in the side wall corresponding to the base column, the steel bar hole extends along the axis of the base column, and the position of the side wall of the base column corresponding to the steel bar hole has an arc-shaped arch.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] like Figure 1-3 As shown: a building anti-floating and pressure relief structure, including a drainage ditch 1 opened in the ground layer, and the ground may be a surface cement floor, or it may be a ground structure such as a basement or a parking garage. A plurality of seepage pipes 2 are arranged along the length direction of the drainage ditch 1. The drainage ditch is a trough body with a long strip structure, and a water collection well is opened at the gathering point to discharge the collected water in time through a water pump. The seepage pipe 2 is composed of a plurality of base columns 3 arranged along the length direction. The base columns are cast with cement, and a ring-shaped steel mesh is added inside. The base column 3 is a pipe body structure with a circular inner groove inside. The base column 3 has a wide-mouth structure on the two sides of the pipe opening corresponding to the base column 3, which expands from the center to the outside. Adjacent base columns 3 are aligned and connected through the wide-mouth structure;
[0019] A water seepage groove 31 is provided on the wide side of the base column 3 along the radial direction of the tube body. The water seepage groove 31 extends from the outer wall to the inner wall of the base column 3 , and the cross section of the water seepage groove 31 is semicircular.
[0020] The seepage pipe is made up of multiple base columns installed together to form a column structure, which is equivalent to a pull-out pile. During construction, a vertical shaft is first excavated, and then the base columns are installed in sequence to form a seepage pipe. The upper opening side of the seepage pipe corresponds to the drainage ditch, and the base column docking position has a seepage ditch. After the base columns are aligned, the seepage ditch on the pipe mouth side is used to infiltrate and store water. The soil is enriched with water, which enters the seepage pipe along the seepage ditch through infiltration, thereby achieving the purpose of pressure relief.
[0021] like Figure 4 As shown: a steel bar hole 32 is opened on the corresponding side wall of the base column 3, and the steel bar hole 32 extends along the axis of the base column 3. The position of the side wall of the base column 3 corresponding to the steel bar hole 32 has an arc-shaped arch, and a steel bar 4 is inserted into the steel bar hole 32. After the base columns are spliced together to form a complete seepage pipe, the corresponding steel bar holes are aligned and steel bars are inserted. At the same time, cement mortar is poured into the steel bar holes to fix and seal the steel bars and the steel bar holes. In this way, multiple base columns can be an integral structure, and the structural function is equivalent to a pull-out pile. At the same time, the wide-mouth structure corresponding to the base column forms a damping, which helps to improve the pull-out effect.
[0022] A base 3 is cast at the bottom of the seepage pipe 2, and the end of the steel bar 4 is bent and embedded in the base 41, and the steel bar 4 is vertically fixed to the base 41. After the vertical shaft is opened, the base is cast at the bottom first, and the steel bar is fixed first, so as to facilitate the installation of the positioning base column, and at the same time improve the adhesion of the seepage pipe and the anti-pulling effect. The base column 3 has an annular groove 33 on the wide side corresponding to the wide mouth, and the annular groove 33 is located on the inner wall of the base column 3. The base column 3 has a reinforcing block 34 at the position corresponding to the steel bar hole 32. It is used to separate the steel bar hole from the inner and outer sides of the base column to prevent water from soaking the steel bar and causing corrosion.
[0023] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
